CHAPTER 1

INTRODUCTION

1.1 PREAMBLE

The growing concern amongst industrialists that graduates of higher institutions lack adequate

practical background preparatory to employment in industries led to the formation of StudentsIndustrial Work Experience Scheme (SIWES) in 1993/1994. It is seen as an opportunity created for

300/400 level students of the university to undergo Industrial Training (IT) as part of the course

requirements outlined by the Nigerian Universities Commission (NUC) in partial fulfillment for the

award of degrees.

Amongst other things, the Work Experience/Training bridges the gap between theoretical

knowledge acquired in the university and the actual industry thereby ensuring the students acquire

industrial skills and experience in their approved course of study. It exposes students to work

methods and techniques in handling equipment and machinery not available in their institutions.

The scheme also affords the students the opportunity to carry out extensive research in preparation

for their year project.

1.3 SCOPE OF WORK

The scope of this report includes my activities as a trainee in the Nigeria Liquefied Natural Gas

company for a period of six months - June to December 2011. It gives a background of the

company, its history, organizational structure and cardinal rules. It also identifies the various

departments and sections in the Production Division and their activities. The different processes inthe liquefaction of natural gas are outlined from feedstock through the trains to the storage tanks

and ships specially designed to transport LNG to customers around the globe. Also, the different

teams in the Project section of the Engineering Department and their functions are outlined and -

using the NLNG Project Management Procedure - stages in the life of a project are chronicled.

Common problems encountered by Trainees and proffered solutions are included in this report.

Future trainees are also advised on what - and what not - to do, before and during SIWES training.

1.4 METHODOLOGY

In writing this report, proper research was made to ensure the desired output was realized. Some of

the steps taken are outlined below:

1. The standard Faculty of Engineering report writing format was followed

2. Information on the history of NLNG was gotten from the companys internal network

(Intranet).3. Site (Plant) visits were made and the Liquefaction process was viewed first hand.

4. The Project management Roadmap used by NLNG was studied and applied in compiling

this report.

5. The internet was consulted to further explain some of the processes/materials/equipments

required to run a Liquefaction plant.

1.5 NIGERIA LIQUEFIED NATURAL GAS

NLNG is an acronym for Nigeria Liquefied Natural Gas Ltd. It is a company owned by four

partners, namely: the Federal Government of Nigeria through NNPC; Shell, Elf and Agip in

descending order of share holding.

It purchases gas from gas producers; in this particular case, from gas plants located at Soku, Obite,

and Obiafu. The gas producers and plant owners at the locations are Shell, Elf, and Agip

2


3/45

respectively. The gas is then passed through pipelines to the plant for liquefaction, before shipment

abroad to customers.

The NLNG plant is located on Bonny Island, Rivers State, Nigeria. It consists of six liquefaction

units (trains) producing 22 million metric 3ones per annum (mmtpa). In addition to the gas plant

there is a gas transmission system and a Residential area where staff are accommodated.

NLNG is not actually a gas producer, but a gas purchaser. Not being a construction, processing or

production company, it operates a very simple process of gas passage through already-buried

pipelines, liquefaction through an already-built plant and transportation to customers in Europe,

America and Asia through already-acquired ships provided by Bonny Gas Transport, a subsidiary

of NLNG.

1.6 BRIEF HISTORY OF NLNGIn November 1995, a Final Investment Decision (FID) was signed by the Shareholders to build an

LNG plant in Finima, Bonny Island, Rivers State. The Base project consisting of two trains, the Gas

Transmission system and the Residential Area was awarded to TSKJ, a consortium of engineering

firms.

Construction at the Plant site commenced in February 1996 and by August 1999, Train 2 was

completed. Production of LNG commenced on September 15, 1999, before Train 1, the second train

of the Base Project came on stream on February 27, 2000.

Train 3, 4 and 5 became operational in November 2002, November 2005, and February 2006

respectively, while train 6 was completed and became operational in December 2007.

The facility, built on 2.27sq.km of land consists of the following:

Six LNG processing units (Trains)

Diversified gas supply and six main dedicated gas transmission pipelines with four

onshore pipelines

Four LNG storage tanks with a capacity of 84,200 cubic meters each

A common fractionation plant to process LPG

Three Condensate storage tanks with a capacity of 36,000 cubic meters each

Four 65,000 cubic meter LPG refrigerated tanks for Propane and Butane

Ten Generators with a total capacity of 400mw

Two LNG export jetties; one of which also exports LPG

CHAPTER 2

LITERATURE REVIEW

2.1 WHAT IS NATURAL GAS AND LNG?

Natural gas - a fossil fuel like coal and crude oil - is a combustible mixture of hydrocarbon gases.

It comes from reservoirs beneath the earths surface. Sometimes it occurs naturally and is produced

by itself (non associated gas) and sometimes it comes to the surface with crude oil (associated gas).

It is primarily made up of methane, but it can also include ethane, propane, butane, carbon and

nitrogen (Shukri T., 2004)

Liquefied natural gas (LNG) is natural gas that has passed through the liquefaction process. Non-

methane components are removed and the gas is cooled to the point that it condenses to a liquid.

This occurs at a temperature of approximately -256F (-161C) at atmospheric pressure (Shukri T.,

2004)

Below is a pie-chart showing the composition of Natural gas as compared with LNG

2.2 BRIEF HISTORY OF LNG

Natural gas liquefaction dates back to the 19th century when British chemist and physicist Michael

Faraday experimented with liquefying different types of gases, including natural gas. German

engineer Karl Von Linde built the first practical compressor refrigeration machine in Munich in

1873. The first LNG plant was built in West Virginia in 1912 and began operation in 1917. The first

commercial liquefaction plant was built in Cleveland, Ohio, in 1941. The LNG was stored in tanks

at atmospheric pressure. The liquefaction of natural gas raised the possibility of its transportation to

distant destinations. In January 1959, the world's first LNG tanker, The Methane Pioneer, a

9

10/45

converted World War II liberty freighter containing five, 7,000 barrel equivalent aluminum

prismatic tanks with balsa wood supports and insulation of plywood and urethane, carried an LNG

cargo from Lake Charles, Louisiana to Canvey Island, United Kingdom. This event demonstrated

that large quantities of liquefied natural gas could be transported safely across the ocean.

Over the next 14 months, seven additional cargoes were delivered with only minor problems.

Following the successful performance ofThe Methane Pioneer, the British Gas Council proceeded

with plans to implement a commercial project to import LNG from Venezuela to Canvey Island.

However, before the commercial agreements could be finalized, large quantities of natural gas were

discovered in Libya and in the gigantic Hassi R' Mel field in Algeria, which are only half the

distance to England as Venezuela. With the start-up of the 260 million cubic feet per day Camel

plant in 1964, the United Kingdom became the world's first LNG importer and Algeria the first

LNG exporter. Algeria has since become a major world supplier of natural gas as LNG.

After the concept was shown to work in the United Kingdom, additional liquefaction plants and

import terminals were constructed in both the Atlantic and Pacific regions. The first exports of LNG

from the U.S. to Asia occurred in 1969 when Alaskan LNG was sent to Japan. The LNG market in

both Europe and Asia continued to grow rapidly from that point on.

The figure below shows worldwide growth in LNG since 1970.

A number of approved, planned, and proposed Liquefied Natural Gas Plants are under development

(British Gas, 2012).

2.3 THE LNG VALUE CHAIN:

This is the supply chain of LNG. It consists of five interdependent stages namely; Gas production,

Liquefaction, Shipping, Re-gasification, and Pipeline delivery. The term value is used because at

each stage, investments are made to convert natural gas from an unusable state to a very important

energy source (Hubbard B., 2006).

Below is a pictorial view of the LNG value chain.

2.3.1 GAS PRODUCTION

This ranges from the prospect generation (development of ideas about where natural gas resources

might occur), to field development and drilling.

2.3.2 LIQUEFACTION

When natural gas- which is predominantly methane- enters the LNG facility, it is pretreated to

produce a feedstock suitable for liquefaction. This pretreatment process includes the removal of

water, acid gases (hydrogen sulfide & carbon dioxide), nitrogen, helium, and mercury.

When all these impurities have been removed, the gas is further conditioned to extract heavier

hydrocarbons- Liquefied Petroleum Gas (LPG) and Natural Gas Liquids (NGL). LNG is a

cryogenic (low temperature of


12/45

The liquefaction process reduces the volume of LNG by a factor of 600, which means that at

-256F, it occupies about 0.16% of the space required for the same amount of gas at room

temperature- 73F, and atmospheric pressure- 101kPa (Shukri T., 2004).

2.3.3 SHIPPING

LNG tankers are double-hulled ships specially designed to convey LNG to customers. A typical

cargo-loading cycle starts with inerting the gas tanks by burning diesel in air to replace oxygen with

CO2. This is done because oxygen supports combustion. LNG can still not be load directly into the

tank though - the CO2 which freezes at -108F will damage the pumps. Liquid LNG is brought into

the vessel and taken along the spray line to the main vaporizer, which boils off the liquid into gas.

This is then warmed up to roughly 68F in the gas heaters and blown into the tanks to displace the

"inert gas". This continues until all the CO2 is removed from the tanks. The next stage is cool-down.

LNG is sprayed into the tanks which vaporizes and starts to cool the tank. When the temperature

reduces to about -220F bulk loading can begin.

After delivering the goods, some LNG (the heel) is left in tanks for return journey as fuel and/or to

keep tanks cold for re-loading (Hubbard B., 2006).

2.3.4 REGASIFICATION TERMINAL

On arrival at the receiving terminal LNG is pumped at atmospheric pressure into double-walled

storage tanks, just like the ones used in the liquefaction plant. To return it to a gaseous state it is

pumped at higher pressure through the various re-gasification facilities components. The pressure

of the re-gasified natural gas is then regulated for end usage (Rosetta, M. J., 2005)

2.3.5 PIPELINE DELIVERY

Gas flowing from higher to lower pressure is the fundamental principle of the natural gas delivery

system. From the re-gasification facility, the gas is transferred to a "gate station." At the gate-

station, the pressure in the line is reduced from transmission levels (200psi to 1500psi) to

distribution levels (0.25psi to 3psi); then an odorant- mercapten- is added, so that consumers can

smell even small quantities of gas this helps in leak detection.

From the gate station, natural gas moves into distribution lines that range from 2 inches to more

than 24 inches in diameter. Within each distribution system, there are sections that operate at

different pressures, with regulators controlling the pressure. Generally speaking, the closer natural

gas gets to a customer, the smaller the pipe diameter is and the lower the pressure is. The end-user

includes homes, factories, power generation plants, etc.

12

2.4 THE NIGERIA LNG PROCESS

The Nigeria LNG is not (directly) involved in the exploration/production, re-gasification and

delivery of natural gas. Rather, the company liquefies natural gas and transports it alongside its

by-products (LPG and Condensate) to its customers. The gas is supplied by Shell, Elf, and Agip,

from their onshore gas fields of Soku, Obiafu and Obite, while the re-gasification and pipeline

delivery is done by the buyers in their respective locations (NLNG, 2007).

The diagram below describes the chain of events leading to the production of LNG, LPG and

Condensate.

2.5 USES OF LNG

Natural gas has many diverse uses. Of all fossil fuels it burns the cleanest - as a result of its

chemical simplicity. During 2006, LNG represented 7.4% of the total worldwide

natural gas consumption (British Petroleum, 2007).

The percentage proportion of its use in different sectors can be seen in the Pie Chart below.

IndustryNatural gas has a number of specific uses in the manufacturing industry.

InPetrochemicals, methanol, produced from natural gas, can be converted into ethylene and

propylene. Ethylene and propylene can also be produced directly from ethane, butane, and

propane separated from other natural gas compounds. In a petro-chemical plant, ethylene and

propylene are converted into materials like polyethylene, PVC plastics, resins, paints,

automotive components, packaging materials, textile fibers, etc.

Through the Haber process, natural gas provides both the energy and feedstock for the

production of ammonia which is used to produce about 90% of the worlds syntheticfertilizer.

Natural gas absorption systems are used extensively in industries to heat and cool water in an

efficient, economical, and environmentally friendly way.

15

Fig 2.5: Proportion of Natural Gas Usage


16/45

In the plastics, pharmaceutical, candy, and recycling industries, moisture filled air can damage

end products during its manufacture. To prevent this, natural gas desiccant systems are used to

dehumidify the factories.

Electricity

Due to reduced tolerances for nuclear and hydro plants, air and water pollution, noise emissions, as

well as the high cost for wind and solar energy, gas-fired power generation has become a very

important method of generating electricity. Modern gas-fired power plants are cleaner, cheaper and

more efficient than other power plants.

Residential

In residential houses, natural gas is used for space heating, water heating and cooking. Cooking

with a natural gas cooker is cheaper than cooking with a kerosene or electric cooker. It is easily

regulated, burns with a clean blue flame and does not emit toxic gases.

Commercial

Natural gas can be used to produce hydrogen which has many applications: it is a primary feedstock

for the chemical industry, a hydrogenating agent, an important commodity for oil refineries, and the

fuel source in hydrogen vehicles.

Compressed natural gas (CNG), which is basically methane compressed to about 250bar, is a

cleaner alternative to otherautomobile fuels such as gasoline (petrol) and diesel. There are about 20

million natural gas vehicles worldwide. The energy efficiency is generally equal to that of gasolineengines, but lower compared with modern diesel engines.

Other

In addition to all these, natural gas is used for metals preheating, glass melting, food processing,

waste treatment & incineration, etc (EIA, 2010).

3.2 DESIGN TEAM

A design engineer creates the initial blueprints and schematics for various structures, systems,

machines, or equipments. They may be given very direct orders or broad conceptual frameworks,and asked to create blueprints that can be translated into working structures. The process often

begins by creating hand-sketches or utilizing CAD programs. These CAD programs allow designers

to draw detailed lines, form curves, and input measurements. Other programs can put designs

through virtual simulations to test their integrity, efficiency, and effectiveness. The most famous

CAD software in use is AutoCAD, created by Autodesk Inc.

3.2.1 THE DESIGN PROCESS

For effective management, the NLNG design process is divided into three hierarchical levels

namely; Conceptual, Basic and Detailed.

Conceptual

In this phase, the problem/improvement is clearly defined and improvement plans are proposed.

General arrangement drawings on the section to be worked on are pulled out from PACER and

marked up. Evaluations on process description, safety and environmental considerations are made

and then a sketch (un-detailed) of the proposed concept is drafted.

BasicIn this phase an overview of the project is done and general design considerations are outlined.

Meteorological and site data is studied and the plot plan is clearly defined. Basis of Design is

carried out and other discipline requirements (Civil, Mechanical, Electrical, etc) are evaluated.

Design requirements, instructions, procedures, standards, specifications and codes are all used as

guidelines for design process. Design calculations are started and the equipment list is updated.

Detailed

This phase is where the final package is produced. Detailed calculations are made, design notes

containing information about the design intent and scope of work is prepared and

construction/fabrication drawings are completed.

Solving a design problem is a contingent process and the solution is subject to unforeseen

complications and changes as it develops. For example, until the Wright brothers actually built and

22


23/45

tested their early gliders, they did not know the problems and difficulties they would face

controlling a powered plane.

Generally speaking, the design process can be divided into 5 steps. The first step is the problem

definition. This definition usually contains a listing of the product or customer requirements and

especially information about product functions and features among other things. In the next step,

relevant information for the design of the product and its functional specifications is obtained. Once

the details of the design are clearly identified, the design team with inputs from other disciplines

generates multiple alternatives to achieve the goals and the requirements of the design. Considering

cost, safety, and other criteria for selection, the more promising alternatives are selected for further

analysis. Detail design and analysis step enables a complete study of the solutions and result in

identification of the final design that best fits the product requirements. Following this step, a

prototype of the design is constructed and functional tests are performed to verify and possibly

modify the design.

When solving a design problem, you may find at any point in the process that you need to go back

to a previous step. The solution you chose may prove unworkable for any number of reasons and

may require redefining the problem, collecting more information, or generating different solutions.

This continuous iterative process is represented in the following.

It is important for a design engineer to thoroughly understand the machines or structures he or she

draws. For example, if a design engineer is contracted to design an interstate petroleum pipeline, he

or she must know how each valve, flange, pump, fitting, etc functions and where each of them

should be placed. By conceptualizing the finished product, the design engineer can create reliable

plans.

23

3.2.2 PIPING DESIGN AND DRAFTING

Most of my activities in this section were centered on the design and drafting of pipes and its

components.

3.2.2.1 PIPES

Applied in a general sense, pipe is a hollow, tubular body used to transport any commodity

possessing flow characteristics such as those found in liquids, gases, vapors, liquefied solids, and

fine powders. So many materials are used in manufacturing pipes. Some of them are concrete,

glass, lead, brass, copper, plastic, aluminum, cast iron, carbon steel and steel alloys. A thorough

understanding of the pipe's intended use is essential as each material has limitations that may make

it inappropriate for a given application.

3.2.2.2 PIPE FITTINGS

Fittings are fabricated pieces of pipe that are used to make changes of direction, branch from a main

pipe, or make a reduction in line size. Because they are part of the piping system, they must match

as closely as possible in specification and rating to the pipe to which they are being attached.

Valves are also pipe fittings but they are usually discussed separately.

The most widely used fittings are outlined below

Elbow: Of all the fittings, the elbow is the one most often used. Simply put, the elbow, or ell, is

used when a pipe changes direction. There are two types of elbows:

90 elbow used to make 90 turns

45 elbow used to make 45 turns

Tee: The name of this fitting comes from its resemblance to the letter T. It is a three-way fitting

used to make perpendicular connections to a pipe. Lines that connect to the main run of pipe are

known as branches. The main run of pipe is often called the header. Two types of tees are used in

the piping industry:

Straight all three outlets are the same pipe size.

Reducing branch outlet is a smaller pipe size.

Reducers: When the piping designer wants to reduce the diameter of a straight run of pipe, a

reducing fitting must be used. The reducer is available in two styles. They are:

24


25/45

Concentric reducer maintains the same centerline at both the large and small ends of the

fitting

Eccentric reducer has offset centerlines that will maintain a flat side on the top or the

bottom of the fitting

Flange: The flange is a ring-shaped device used to join two pipes together, with a gasket in the

middle. Flanged connections are used as an alternative to welding because they can be easily

disassembled for shipping, routine inspection, maintenance, or replacement. Flanged connections

are preferred over threaded connections because threading large bore pipe is not an economical or

reliable operation.

The different types of flanges are; Weld neck, Threaded, Socket weld, Slip-on, Lap-joint, Blind andOrifice Flange.

To complete any flanged assembly, two additional items are required: bolts and gaskets. Bolts are

used to hold mating flanges, nozzles, or valves together while gaskets are used to create a leak-

proof seal between

25

26/45

3.2.2.3 VALVES

By definition, a valve is a device that controls the flow of a fluid. However, today's valves can also

control the flow rate, volume, pressure, and the direction of a fluid within a pipe. They can turn on

or off, regulate, modulate, or isolate. They can range in size from a fraction of a centimeter to as

large as 10 meters in diameter and can vary in complexity from a simple brass valve, available at

the local hardware store, to a precision-designed, highly sophisticated coolant system control valve

made of exotic metal alloy used in a nuclear reactor. Valves also can control the flow of all types of

commodities; from the thinnest gas to highly corrosive chemicals. They can handle temperatures

from the cryogenic region to molten metal exceeding 1500F, and they can contain pressures

ranging from severe vacuum to 10,000 kgm.

There are so many types of valves in use today, depending on their functions, mode of operation,

throttling/non-throttling ability, etc. The most common types are Gate, Globe, Butterfly, Check,

Angle, Control, Relief valve, etc.

3.2.2.4 PIPING ISOMETRIC

An isometric oriso is a type of three-dimensional drawing known as a pictorial. They are developed

using the three primary dimensions of an object: height, width, and depth. To include these

dimensions in a single view, an isometric must be drawn on axes that measure 30 from the

horizontal plane.

When a Design Drafting Request (DDR) is sent to a Piping Engineer, the General Arrangement

(GA) drawing of the affected section is consulted. Site visits are made and on-ground

measurements are taken. The new pipeline is then drafted using AutoCAD and all the fittings are

depicted using their standard symbols. The Materials Take off (MTO) - being a list of all the

materials, their sizes and specifications, etc., required on that iso is included in the drawing.

3.3 CONSTRUCTION TEAM

Construction engineering is a professional discipline that deals with the designing, planning,

construction and management of infrastructures such as highways, pipelines, buildings, dams,

utilities, etc. They are unique because they are a cross between civil/mechanical/electrical engineers

and construction managers. Construction engineers learn the design aspect much like the discipline

engineers and construction site management functions much like construction managers. The

construction team is in charge of supervising project construction activities.

When the design team completes the project design package it is reviewed by the PEO/5 team to

ensure that it is constructible, and is in line with standard requirements. When certified okay,

materials are ordered by Project Leader, received and inspected by PEO/5 (in conjunction with

PEQ- Inspection department). Work is further broken down to discrete packages and a more

detailed scheduling is done.

A project construction coordinator (PCC) is assigned to supervise the construction and installation

works. It is his duty to prepare work orders, issue site instructions and monitor the project to ensure

that it is being executed according to the design; and any (necessary) deviation/non-conformance is

reported to the project leader.

When construction is complete, reports are made, pre-commissioning tests are carried out, punch-

lists are developed, and commissioning is done. As-Built drawings are then marked up and

Operations/Maintenance teams are given the project manual (updates).

3.3.1 SOME CONSTRUCTION TERMS/ACTIVITIES

PTW (Permit to work) is a permit issued by the Operations department before any job is carried

out in the plant.

Non-destructive testing (NDT) is a group of analysis techniques used to evaluate the properties of

a material, component or system without causing damage to the material. It is done- especially- to

test the integrity of weld joints. Common NDT methods include ultrasonic, magnetic-particle,

liquid penetrant, remote visual inspection (RVI), etc.

A hydrostatic test is the most common method employed for testing the integrity of pipes and

vessels. The test involves running water- which is often dyed for visibility- in the pipe or vessel to

ensure it will not leak or be damaged. The test pressure is always considerably higher than the

27


28/45

operating pressure to give a margin for safety. This margin for safety is typically 166.66%. For

example if a pipe is rated to convey fluid flowing at 200bar, the pipe will be tested at 332bar.

Construction technical Query is a query raised by the construction team when there is a

(necessary) deviation from the original design/work plan. The CTQ, when raised, has to be

approved by the design engineer or the project leader before the deviation can be implemented

When there has been a change in the original design or scope without a CTQ to back it up, a Non-

Conformance Report is raised and construction activities are paused till all parties agree on the

way forward.

The Punch List summarizes the items, which have not been fully completed or still deviate from

the specified requirements. Items on the Punch List may be either Type A, (needs to be corrected

prior to project handover or start up) or Type B (needs to be corrected as soon as possible, but can

be done after project handover or start up).

3.4 PROJECT TEAM

The Project Engineer, also called Project Leader (PL) manages a project from the Develop phase to

the Close out phase. This involves planning, monitoring and controlling all aspects of a project in

order to achieve the objectives within the agreed time and budget limits.

ROLES

A project leader must;

* Understand the project objectives,

* Determine the best approach to meet the objectives,

* Address the various needs and expectations of the stakeholders

* Coordinate the project team

* Balance all competing constraints Cost, Time, Resources, Quality, etc.

For a project Leader to be effective, he must have:

Technical skills Technical competence in the subject matter;

Organizational skills Project planning, scheduling, effective communication, and;

People skills Coordinating team members and managing the expectations of stakeholders.

Also a background in Design and Construction Engineering makes for a better Project engineer.

3.5 PROJECTS

A Project is a unique temporary endeavor that has a start and close out date with the main purpose

of developing organization or business needs whilst improving on the existing facilities.

Projects are managed by Project Engineering PEO & NPX teams. The types of projects managed

include:

Plant Improvement Projects (managed by PEO)

Simple Engineering Changes (SEC)

Major Capital Projects (managed by NPX)

Sustainable Development Projects (managed by NPX)

3.6 LIFE OF A PROJECT

For proper planning and effective management, the activities involved in a project can be divided

into 5 phases. These are the Assess, Select, Develop, Execute and Close-out phases.

To understand the (NLNG) Project management procedure, this section will take us through the life

of a project, from start to finish.

3.6.1 PRE-ASSESS/ SCOUTING PHASE

Before the Assess phase, something is happening. Someone (the originator) has identified a

business opportunity, a deficiency, or a problem that requires an engineering change in the plant.

The originator puts his thoughts together, raises a PDR through PEO/4 (Project Services), and

prepares a proposal to be presented to the DRT. The DRT evaluates the proposal to ensure it is

appropriately framed and is aligned with the companys business plan. Upon approval, the

improvement request becomes a project and moves to the assess phase.

3.6.2 ASSESS PHASE

After DRT approval, the PMF reviews and challenges the technical aspect, the execution strategy

and the commercial viability of the project, and makes the decision to either progress it into the

32

ASSESS SELECT DEVELOP EXECUTECLOSE

Fig 3.5: Project Phases


33/45

Select Phase; put it on hold; or totally cancel it. The PMF also ranks the project for High, Medium

or Low implementation prioritization based on Project criticality, urgency, business opportunity

and/or resource availability.

If the Job Coordinator requires funds to execute the Select Phase Study then the PMF will refer the

PDR to the CRF unless the total project value will be less than $50,000; which is within the PMF

Delegated Financial Authority.

If, for any PDR, the PMF are convinced that the Select Phase study is unnecessary they will advise

the Originator to proceed directly to the Develop Phase.

The Assess Phase deliverables required for PMF presentation include:

a) PDR Form filled and signed off by the originator and approval parties.

b) Short Project Memo covering issues in the PDR that need additional detail like

Project Scope and Basis of Design

Project Driver

Project Execution Strategy

Resource Requirement

Business Case / Justification (License to operate or Business Opportunity)

c) Relevant drawings, sketches, photographs and inspection or study report (where applicable).

d) 50% Cost Estimate

e) Project Schedule (Level 1)

After PMF approval, the project moves to the Select phase.

3.6.3 SELECT PHASE

The objective of the Select phase is to investigate all problems, improvements, and opportunities in

respect of the project and to compare alternative solutions in realization of the project.

The Select Phase Study Report must compare the various options (both technically and

commercially), recommend the preferred option and refine the justification. For the recommended

solution, the Job Coordinator shall prepare the Preliminary Scope of Work document which is part

of the Select phase Study Report.

For the Select Phase:

The Originator develops the PDR deliverables further to meet the requirement of the Select

Phase.

33


34/45

Originator will have to carry out Conceptual design to develop the selected options for the

project with incorporation of Lessons Learned and issue a Basic Design Package (BDP).

Contracting strategy has to be firmed up.

Risk Register established and further developed.

A +/-30% CAPEX Cost Estimate is prepared by PEO/4 based on the Basic Design Package, the

Risk Register and the approved Execution and Contracting Strategy.

Originator seeks and obtains approvals from his/her Manager or Asset Holder, and submits the

Select Phase PDR Package to PEO/4.

PEO/4 reviews the PDR submission for completeness with the Select Phase Checklist,

processes and schedules it for PMF/CRF review meetings.

Originator presents the project developments proposal to the PMF with a simple presentation

slide. PMF reviews and challenges the technical aspect, the execution strategy and the

commercial viability of the project, approves/rejects the project to go the Develop Phase.

If project proposal is approved to proceed to the Develop Phase and needs preliminary funding

in the Develop Phase, it is scheduled for and presented to the CRF for review and Initial

Investment Decision (IID) budget appropriation approval. Where IID is not required, the

Develop Phase design is done In-House by design team (i.e. PEO/1 and/or PEO/2) and reviewed

internally by subject matter disciplines.

3.6.4 DEVELOP PHASE

The objective of the Develop phase is to further define the Scope of Work, prepare the detailed

design and prepare a +/-15% cost estimate for implementing the recommended solution detailed in

the Select Phase Study Report.

The Develop Phase Report deliverables include as a minimum the following:

a) Develop Phase Approval Form filled and signed off by the PL, the PLs supervisor, the

Business Owner and the relevant technical authorities and stakeholders.

b) Develop Phase Study Report covering the following standard headings:

Executive Summary

Project Justification and Estimate

Project Scope

34


35/45

Implementation Strategy

Roles and Responsibilities

Design Basis

Operational Impact/Shutdown Requirements

Project Risks

Construction, Operability, Maintainability Issues

Detailed Design, Marked-up Drawings, Sketches, Photographs, etc

Based on the deliverables tendered, the PMF endorses the proposal and directs it to the appropriate

Delegated Financial Authority for approval.

The PL develops the PDR deliverables further to meet the requirements of a Final Investment

Decision (FID) A +/-15% CAPEX Cost Estimate is prepared by PEO/4 based on the Design Package, the Risk

Register and the approved Execution and Contracting Strategy.

PL raises FID request to go to Execute Phase using the Develop Phase PDR Form

PL fills out the Develop Phase Form and obtains the relevant project and technical/discipline

approvals and submits to PEO/4.

PEO/4 reviews the PDR submission for completeness with the Develop Phase Checklist,

processes the Develop Phase PDR Package for PMF/CRF review meetings and schedules the

PMF/CRF meetings.

PL presents the project to the PMF/CRF with a simple presentation slide.

PMF reviews and challenge the technical aspect, the execution strategy and the commercial

viability of the project, approves/rejects the project to go the Execute Phase.

If project proposal is approved to proceed to the Execute Phase, it is scheduled for, and

presented to the CRF for FID budget appropriation approval.

3.6.5 EXECUTE PHASE

The objective of the Execute phase is to carryout Detailed Design, Procurement, Complete

Installation/Construction, Commissioning, and Operational hand-over of a project. Activities in this

phase are chronicled below:

35


36/45

Detailed Design/Engineering

Detailed design is done in the execute phase only for EPC projects, while it is done in the

develop phase for non-EPC projects.

The PL raises DDR to the design team to carry out the required design work. The Senior Design Engineer appoints a Project Design Coordinator (PDC) to coordinate the

design work.

The PDC ensures that the design is carried out in accordance with the Design Management

Procedure

The PDC produces Issue for Comments (IFC) design pack and presents to all stakeholders,

including technical discipline authorities and construction team, for review and comments.

The PDC updates the IFC design pack based on stakeholders review comments, and

produces Issue for Approval (IFA) for the PL.

The PL reconfirms from stakeholders that IFA design pack has included all IFC comments

and obtains all relevant stakeholders signatures.

Upon confirmation from stakeholders that the IFA design pack is accurate and complete, the

PL returns the IFA design pack to PDC to produce Approved for Construction (AFC)

package.

The PDC then issues the Approved for Construction (AFC) package to the PL.

Procurement

The Project Leader (PL) is responsible for all procurement and contracting activities required to

complete the work scope, in accordance with the CPM procedures. The PL will also order relevant

materials by raising a Materials Request (MR), in line with the MTO received from PDC, which

shall be processed by CPM until delivery to Bonny.

Upon arrival of the ordered materials the PL notifies the PCC, who will then be responsible for

inspection and acceptance/rejection of the delivered materials to be used for the construction of the

project. The PCC will notify the PL of any rejected materials for replacement and incomplete

materials for complete delivery.

Construction

The Project Leader (PL) is accountable for providing Construction Work pack to the PCC, while

the PCC ensures that it is adequate for the work scope to be carried-out.

36


37/45

The assigned PCC is responsible for the construction management; including supervision of the

installation/construction works, and commissioning, while the Project Leader retains the overall

responsibility for the project management.

For the construction part of Execute phase:

The PCC receives the Construction Work pack from the PL and reconfirms completeness.

Before the start of construction, the PCC ensures completeness of all materials i.e. received

and accepted. The PCC also ensures the replacement of all rejected materials and delivery of

incomplete materials (if any).

The PL organizes the Project Kick-off meeting, with the PCC and other relevant

stakeholders, in attendance.

The PCC supervises the project, manages all construction issues, conducts regular

construction progress meetings, and provides regular feedback to the PL.

When there are changes to scope during construction, or deviation, queries and non-

conformances, the PCC manages such in accordance with the Project

Change/Queries/Deviations and Non-Conformance procedure.

PCC manages the Commissioning activities, where relevant to the project.

PCC carries out and closes all punch list items, to ensure that a functional asset is delivered.

Upon confirmation from the Asset Holder and/or Business Owner and/or Originator, that the

construction/installation work is complete, all punch list items closed, and a functional asset

has been delivered, the PCC hands the project over to the PL for commencement of close-

out activities.

3.6.6 CLOSE OUT PHASE

Upon completion of Implementation Work-packs executed by a Contractor, the PL issues a

Certificate of Acceptance.

The PL issues a Handover Certificate to the Asset Holder

The PL must obtain Complete As-builts of the project from the PCC.

Upon settlement of all accounts the PL liaises with PEO/4 to raise and submit to Finance

Department (FNP) a Financial Closure Note.

The PL, together with CPM, reviews the contractors performance by completing the

Contractor Close-Out Form.

3.7 SOME LIVE PROJECTS I WITNESSED

09/PDR/068: Condensate Stabilization unit Debottlenecking Project: Execute phase

The scope of the Condensate Stabilization Unit Debottlenecking Project consists of all design and

engineering activities required for the modification and upgrade of the stabilization system in theLNG plant so as to accommodate increase in spiking rate of condensate coming from Soku gas

plant at the current rate of 13,000bbl/d to 60,000bbl/d. The project is currently undergoing design

and the BDEP was prepared by Design contractors, Dover Engineering ltd, under the supervision of

the PDC.

06/PDR/059: Fabricate and Install DRY RISERS on Trains 4, 5, 6:Execute Phase

Dry Risers are vertical pipes installed in a building/structure for fire fighting purposes.

The need for the design of dry risers on Trains 4, 5, & 6 came on the search for a suitable means of

spreading firewater on the different platform elevations of each train over the entire span with only

the monitors and hydrants serving as a source and distribution for the ground level and upper

heights.

Dry rising mains provide a readily available means of delivering considerable quantities of water to

extinguish or to prevent the spread of fire. Since this is the case, particular attention must be paid to

the design of the system to ensure that valves are correctly sited with adequate space to enable

efficient use of the equipment.

The typical dry riser system considered in this design basically will consist of a 150mm diameter

pipe with a quadruple inlet connection at ground level, two outlet valves on each landing platform,

and an automatic air release valve at the highest riser point.

06/PDR/101: Additional Foam Skid & Fire truck Tie-in point at Condensate tanks: Execute

Phase

As a result of a fire outbreak on one of the condensate tanks it was revealed that presently, only one

portable Foam Skid is available and is usually out of service whenever maintenance needs to be

carried out. This is unacceptable from a safety point of view. Again, a third condensate tank has

been approved for construction and when it is completed and is in operation, the fire fighting

coverage will no longer be adequate with one Foam Skid available unless another Foam Skid and a

38


39/45

Mobile Foam truck is deployed. This is because the third condensate tank is a long way from the

existing Foam Skid.

This project provides an extra Foam Skid and a Tie-In point between the existing and the new Foam

Skids to facilitate a direct hook-up to the Foam truck. This will allow for:

Effective maintenance to be carried out on the existing Foam Skid while maintaining

100% cover

Provision for a standby Foam truck to hook into the connection point and fight fire as a

back-up.

08/PDR/034: MSC Yard Fire Protection Upgrade:Execute Phase

Currently, the MSC yard does not have any fire water ring mains and the existing buildings also do

not have proper fire alarm/detection protection system.

The two existing hydrant points in the MSC yard are connected to a portable water supply line with

insufficient fire water pressure and the existing fire alarm systems are mostly stand alone manual

call points connected to local beacons and horns while buildings such as Train 4 and 5 spare

warehouse are not equipped with any fire alarm/detection system.

These existing conditions fall short of Shell/NLNG DEP for onshore installation fire protection.

Hence the project proposes to close out the identified gaps by upgrading the fire water and safety

systems at the MSC contractors yard to meet NLNG standards.

4.1 PROBLEMS ENCOUNTERED DURING SIWES

During my training I was faced with a few problems but the most challenging of them are described

below.

DISTANCE FROM HOME/ACCOMMODATION PROBLEMS

Bonny, where NLNG is located is an Island and can be assessed by only land and air, hence

accommodation is relatively expensive. Before we took the SIWES placement test, we were

informed that accommodation will not be provided us and we should make arrangements for

ourselves. We all agreed; but due to the fact that SIWES placement in a good firm is not easy to

come by, some of us were invited didnt think much about accommodation, believing that when we

get there we will find a solution.

That solution was not very easy to come by. Some trainees had to squat with those who had houses.

Others had to spend the first few days in Hotels and Guest Houses pending when they found a semi-

permanent residence. Those who did not have enough money to pay for a hotel room nor friends to

squat with were virtually homeless.

ACCEPTABILITY

Based on (probably) past experience with some SIWES trainees, some staff of the company alreadyhad pre-conceived notions on Trainees in general. They think were lazy, no-do-gooders, and/or a

nuisance. Some also thought all students from the University of Port Harcourt are cultists. Proving

otherwise to them was a challenge at first, but with time they came to understand that we were

different.

BLENDING IN

Basically, the essence of the SIWES programme is to bridge the gap between the theoretical and the

practical world. Many of the things we saw here were novel to us; but some members of staff

expected us to understand them immediately. At first we were too timid to ask questions and

sometimes they foisted tasks we couldnt understand on us. It always took extra initiative-

sometimes after several blunders- to get them done.

DEPARTMENTALIZING

40


41/45

We were not given a choice on departments or sections. We were randomly posted to different

sections of the company based on our disciplines. At first I wanted to be in the Maintenance section

of the Engineering department but I was posted to Engineering Projects section. Although I finally

got to appreciate the section, some other trainees were not so lucky. They were posted to

departments/sections that had little or no relevance to their discipline; For example, a geology

student was posted to Human resources and a Chemical engineering student was posted to External

relations.

CHEAP LABOUR

The SIWES programme is obviously for our own good. While we are being developed, it is only

right that the company benefits from us as well; but not to the extent of turning us into errand

boys/girls. Some errands we were sent were cumbersome, irrelevant to our training and sometimes

demeaning.

NO PREPARED TRAINING PLAN FOR TRAINEES

Many sections have no prepared training plan for Trainees. Obviously, anything that is unplanned

works haphazardly. This free-style method of training is not effective as so many things that could

and should be learnt are not; more effort is devoted to irrelevant activities and generally time, which

is limited, is not maximized.

4.2 RELEVANCE OF THE PROGRAMME

The SIWES programme is relevant in so many ways. Outlined below are a few of them.

It bridges the gap between theoretical knowledge acquired in the university and the

actual industry thereby ensuring the students acquire industrial skills and experience in

their approved course of study

It acquaints students with the practical skills needed to make one productive.

It prepares students for the industrial work situation which they are likely to meet after

graduation.

It exposes students to work methods and techniques in handling equipment and

machinery not available in their institutions.

It provides students with an opportunity to apply their knowledge in real work situation.

It enlists and strengthens employers involvement in the entire educational process.

41


42/45

It motivates students to study hard and do well in school so that after graduation, they

could be employed in a similar place.

CHAPTER 5

5.1 CONCLUSION

Basically, the SIWES programme was precipitated by the need for undergraduates to acquire

Industrial skills in their course of study. NLNG through its Human Resources Department has

offered that platform and I must confess that they are world class.

Working here has improved me in so many ways. I have gotten to appreciate the importance of

theoretical knowledge as a necessary background to industrial practices. I have also learnt several

new things like, Project management, Construction management, AutoCAD, Document control,

Time management, Health and Environmental safety and office/business ethics.

All this knowledge cannot be gotten in classrooms; hence the importance of the programme is huge.

5.2 IMPROVEMENTS/ADVICE TO SIWES MANAGERS

As wonderful as this programme may be, it has a few flaws. Outlined below are my suggestions for

improvement and advice to SIWES managers.

ADVERTISING

The public media, especially the internet, should be used to advertise the organizations willingness

to accept applications for the training programme. They should also interface with the institutions

SIWES unit so that the information can be cascaded to the intending trainees.

PREPARED TRAINING LADDER FOR TRAINEES

All departments and sections should have a standard training schedule for SIWES trainees. This

will ensure that the few months spent there are maximally utilized.

DEPARTMENT POSTING

I think all accepted trainees should have a choice in selecting the department or section they are

posted to. This will eliminate the challenge of undergoing training in a department that is not

relevant to your course of study.

ACCOMODATION

42


43/45

Companies (like NLNG Bonny) in offshore locations should provide accommodation for trainees.

This will really help to reduce the stress of finding suitable places of residence, especially those

who came from very far places.

LABOUR

The Training programme has been used by some companies as a means to get cheap labour. Some

trainees work harder than full employees but are paid a tiny fraction of what the employees earn.

The programme should strictly be for learning and not a means to exploit the students energy.

5.3 ADVICE TO FUTURE TRAINEES

There are so many things intending trainees should know. Outlined are a few major ones that if

adhered to, will go a long way in helping them.

Start sending applications as early as possible. Do not wait till the end of the 1st semester of

your IT year before you start looking for an employer. This will ensure that you get placement

on time so that the stipulated six months will be completed before a new school session begins

Send as many applications to as many companies as possible. This will ensure that when

invited, you get to select the most suitable firm.

Do not put all your eggs in one basket. Always have a back-up plan. For example in NLNG,

so many people were informed that they passed the recruitment test. At the end of the day

they were not invited because the maximum number of trainees the company can take at a

time is fifty.

Dont fail to attend the SIWES orientation programme organized by the school before going

on attachment

Forward the Offer Letter given to you at your place of attachment to your department and the

SIWES unit, so that an institution based supervisor can be allotted to you.

Adhere strictly to the rules and regulations of the organization where you are attached

Keep a proper record of everything you do throughout your training. This should be done in

your log-book and duly signed by your supervisor.

Protect your employers assets. This includes physical properties and confidential information

43


44/45

Keep in touch with your school and your departmental focal person, so you will be up to date

on information that might benefit you

Future trainees from your school will be accepted or rejected based on your performance. Do

well to do well.

Finally, when you get to your place of attachment, do not forget that you are ambassadors of

your various institutions. Be a Good Ambassador!
