1.4 Summary of Practical Training
For the practical training, I was fortunate to get the opportunity to work at
Germanischer Lloyd (GL) Noble Denton, a world class technical service provider for the
oil and gas industry located in Kuala Lumpur. GL Noble Denton help to design, build,
install and operate oil and gas onshore, maritime and offshore assets to ensure safety,
sustainability and superior value. I was able to get hands-on view of what it was like to
work in the oil and gas industry. My supervisors were more than willing to let me get
involved and I was able to help them out on many different fronts. In addition to collect all
relevant documents from client, scanning, photocopying and filling, I was taught how to
use Galiom which is a combined asset integrity management and risk-based inspection
and maintenance tool that can be used for any oil, gas, or petrochemical facility. I learned
how to go through and taking a relevant data from process flow diagram (PFD), piping
and instrumentation diagram (PNID), prepare minute of meeting and schedule planning
and learned the overall process in oil and gas production. I learned how to select thickness
measurement locations as well as utilize relevant information from the previous data to
create the desired output. I set up and took part in meeting and meet the clients. I even got
to take part in a project where I was assigned to select inspection test points for Balal Field
Development Project. Moreover, I also involve with Murphy RBI Development Project
2010 at Bintulu Onshore Receiving Facilities (BORF). At the end of the practical training,
I was to present what I had learned and also come up with my personal opinions of the
lessons that I learned during the practical training period. I presented my finished practical
training in the form of a Power-Point presentation on the final day of my internship and it
was received extremely well. I feel so lucky that I got this opportunity, especially at such a
turbulent time in GL. I feel that I experienced a very unique point in the engineering field
and that experience will make me well prepared for the real world that I am about to
enter into. I greatly enjoyed and thrived in the fast-paced lifestyle that comes with this
kind of job and the Kuala Lumpur environment where it was located. I really appreciate
the people who have helped me to make this happen, and I wouldnt trade this practical
training experience for anything.

2.3 Asset Integrity Management Department
Asset integrity is an asset has integrity when it performs as specified and is being
operated and maintained as specified so that the combination of the likelihood of failure
and the consequence of failure makes the risk to people, environment, assets and
company reputation arising from its failure is as low as reasonably practicable. Plant
integrity, safety, and reliability are major concerns to all plant operators and managers.
The primary objective of AIM is to maintain the asset in a fit-for-service condition while
extending its remaining life in the most reliable, safe, and cost-effective manner. AIM for
an operating facility, is focused on the operating and technical integrity:
1. Is the facility being operated within the design parameters?
2. Is the facility being maintained as required within the time frame required?
3. Is the facility being inspected as required with an effective, planned and written
inspection scheme?
In addition to regulatory and company requirements, operators of facilities and
pipelines have the following business needs:
1. Maximizing production
2. Reducing lost income due to unplanned shutdown
3. Optimizing inspection and maintenance costs.
4. Maximizing asset value.
5. Maintaining an auditable system
-
7/27/2019 Final Report Practical
14/59

2.3.1 Risk Based Inspection
RBI is an approach to AIM which seeks to optimize inspection activities based on
the likelihood and consequence of failure of components and systems. Using this
methodology, inspection frequency is highest for the highest risk systems, and the
interval between inspections if lengthened for those systems which have the lowest risk.
This common-sense approach to inspection can significantly increase a plants on-stream
availability.
The primary objective in implementing an RBI programme is to produce an
inspection strategy that clearly states:
1. Which equipment needs to be inspected?
2. The optimum interval between inspections.
3. To use the right technique to detect the defects likely to develop for that a
particular component.
In a typical RBI, study will involve:
1. Establish the qualitative or quantitative risk-ranking level of existing equipment,
and determine the respective risk acceptance level based on standard industry
practice and customer defined criteria.
2. Assess the process operating parameters of CO2 mole fraction which impact
production, mechanical integrity, and rates of corrosion or degradation.
3. Review technical specifications and materials of construction, and provide gap
analysis, recommendations, and turn-around prioritization.
-
7/27/2019 Final Report Practical
15/59

4. Assessment of risks associated with equipment degradation and corrosion rates
using industry standards, such as API-580, API-579, and API-581.
5. Determine remaining life for each component, and determine the appropriate
inspection intervals.
6. Specify the necessary inspection and maintenance tasks and intervals based on the
risk ranking.
2.3.2 Data Management Solution
Even moderate scale Asset Integrity Management programmes produce massive
quantities of data that must be effectively managed. Because the databases that result
from AIM implementations can be so large, even simple data entry tasks can involve so
many data points that they overwhelm even well staffed inspection departments.
Furthermore, most standard corrosion monitoring software packages are limited in
their ability to dynamically link data in the database to CAD drawings or field sketches.
Also standard systems typically identify visual observations as open or closed, but do not
effectively track status in terms of whether or not the remediation deadline is imminent or
overdue.
GL provides services which can address these common data management issues.
GL applies an AIM approach with a sophisticated RBI and AIM tool (GALIOM). Galiom
can be utilized as a one-off RBI equipment risk assessment software generating reports
that identify the associated risk ranking of each piece of equipment, or as a fully
integrated application.
-
7/27/2019 Final Report Practical
16/59
16
Galiom starts by establishing an asset hierarchy for the facility by breaking down
each business unit into an area, complex, location, platform, functional group, tag, piece
of equipment, feature or component and measuring or test points. The next step involves
entering the design and operating data for each equipment tag into a database for the
specific facility.
Galiom calculates risk by multiplying the consequences of failure (CoF) by the
probability of failure (PoF). CoF is assessed in four categories the consequences for
people (safety), the environment, the asset (cost of damage or downtime) and the owner's
or operator's reputation. PoF is appraised by considering factors such as the operation and
design of an asset, corrosion, the impact on third parties, seismic activity, process
stability and probability of failure modes.
Galiom uses the CoF-PoF equation to identify the resultant risk and display it on a
5x5 risk matrix. At the same time the asset hierarchy is colour-coded to display the level
of risk for each piece of equipment, enabling the operator or owner to immediately
identify the asset risk status. Risk within GALIOM is displayed on a 5 by 5 Matrix. The
red colour areas are classed as Higher Risk, unacceptable risk, which should be addressed
with some form of Mitigation Measure immediately. Risk increases from the Top Left to
the Bottom Right. Ideally the aim is to have all equipment in the Green zones however;
this is not realistic and is where an ALARP (As Low As Reasonably Practicable)
principle is used.
ALARP stands for As Low As Reasonably Practicable, and is a term often used in
safety-critical and high-integrity systems. The ALARP principle is that the residual risk
shall be as low as reasonably practicable.
ForRiskto be ALARP it must be possible to demonstrate that the cost involved in
reducing the risk further would be grossly disproportionate to the benefit gained. The
ALARP principle arises from the fact that it would be possible to spend infinite time,
effort and money attempting to reduce a risk to zero however it should not be understood
as simply a quantitative measure of benefit against detriment. It is a judgement of the

17
balance of risk and societal benefit. Risk being the multiplication of CoF and PoF can be
displayed on a 5x5 matrix in table 1 below.
Table 1: Risk Display
GALIOM also uses the same color coding in the Asset Hierarchy to display Risk.
Each piece of equipment is Risk Ranked and that ranking is rolled up to the highest level
so that at a glance the Facility Risk can be seen. Just light a Traffic Light. Asset
Hierarchy to display risk can be seen from figure 3 below:

3.2 Assignment
There are two assignments that had been given:
1. Definition of AIM, RBI, MAWP and MAWT. The details can be viewed in
Appendix I.
2. Material Selection. The details can be viewed in Appendix II.
3.3 Galiom Training
I learned about Galiom software in term of understanding asset hierarchy at first.
Functional groups, tag and test point need to be assigned. A part of that, I was taught to
insert the data into Galiom. There are some functions that need to be understood first
before we input any data that related with calculation. As an engineer, we need to
understand why the selected data had been chosen and input to Galiom. Understanding
the operating manual for the facilities is very important in order to understand the process
flow diagram or any related drawings and documents. By doing that, we analyze and can
detect any error in Galiom so the result of RBI can be accurate.

3.4 Introduction of Oil and Gas Production
Oil and gas industry is a massive industry. We need to know how oil and gas
being produced in order to know the system and the functions for all of the equipments
that are used in oil and gas industry. Wellhead, piping, separation, pump, compressor,
christmas tree are some of the main components in oil and gas production.
3.5 Meeting
AIM department has weekly meetings. The purpose conducting such meeting is to
update our tasks and to discuss any problem that need to be solved so we are on track on
our project schedule. In the meeting, one person will be the chairman and another person
will write the minutes of meeting. A sample minute of meeting can be viewed in
Appendix III.
3.5 Summary
I gained a lot of experience in this practical training. The most important aspect
that I have learned is I know what oil and gas industry is about. A lot of company are
involved and depends on each other. From the geologist that find reservoir and the
engineer that drills and build platform until the refinery to process oil, these whole
processes needs a lot of man power. The summary of my practical training in 10 weeks
can be seen from table 2 below:

CHAPTER 4
IOOC PROJECT
4.1 Introduction
After the victory of the Islamic Revolution of Iran, all partnership contracts with
aforementioned companies were abolished at the decree or the Supreme Council of the
Islamic Revolution in 1979, and a year later, the Iranian Offshore Oil Company (IOOC)
was established by combining those companies. The objective underlying establishment
of IOOC was to achieve an optimized production as well as safeguarding oil and gas
reservoirs in the Persian Gulf area along with an increase in the production rate and
prevention of oil and gas migration in the common fields, and in a word, to administer
the entire oil and gas fields in the Persian Gulf where the American and European
companies had previously carried out the oil activities.

The Balal Oil Field is the one of field in the Persian Gulf. The Balal field is a
dome structure analogous to a circle with a diameter of 2.5 km. The area of the field, at
top of Hith-Arab formation, is about 16 km2. The main reservoir of this field is Arab
formation composed of carbonate, and subdivided into 7 layers. The secondary structures
in this field are Khatiyah, Shuaiba and Khuf respectively. The average depth of reservoir
is about 6000 ft containing a light and relatively good quality crude oil with API of 44
degrees. The ultimate recoverable oil reserve is estimated to be 117 MMSTB which will
be achieved by daily water injection rate of 50000 BWPD and considering the original oil
in place of 293 million barrels, the recovery factor will be 40% for a period of 14 years
which is envisaged to be a very good recovery factor.
4.2 Project Description
Our team has to conduct AIM and RBI for Balal Offshore Oil Complex for IOOC.
The scope of work shall be done in Balals facilities specified below:
1. One wellhead platform
2. One flare platform

7. Preventive Maintenance Schedule, Visual % NDE, identifying Next Inspection
Due Date and Inspection Methodology.
4.6 Project Schedule
In order to complete all of the tasks in this project on time, scheduling all of the
tasks are necessary. This project schedule is also required by the clients to see theprogress of our work. Project schedule can be seen from figure 7 below:
-

Figure 6: Project Schedule
4.7 Thickness Measurement Locations
My scope of work is to develop the next inspection due date. In order to do that,
we need to identify thickness measurement locations (TMLs). TMLs are specific areas
along the piping circuit where inspections are to be made. The nature of the TML varies
according to its location in the piping system. For selection of TMLs, we consider the
potential for localized corrosion and service-specific corrosion. Each piping system need
to be monitored by taking thickness measurements at TMLs. Based on piping inspection
code, piping circuit with high potential consequences if failure should occur and those
subject to higher corrosion rates or localized corrosion will normally have more TMLs
and be monitored more frequently. In order to develop next inspection due date, the
interval between piping inspections shall be established and maintained using corrosion
rate, remaining life calculations, piping service classification, applicable jurisdictional

requirements, judgment of the inspector, the piping engineer, the piping engineer
supervisor, or a corrosion specialist, based on operating conditions, previous inspection
history, current inspection results, and conditions that may warrant supplemental
inspections.
The minimum thickness at each TML can be located by ultrasonic scanning or
radiography. The thinnest reading or an average of several measurements readings taken
within the area of a test point need to be recorded and used to calculate corrosion rates,
remaining life, and the next inspection date. TMLs need to be marked on inspection
drawings and on the piping system to allow repetitive measurements at the same TMLs.
This recording procedure provides data for more accurate corrosion rate determination.
We decide that more TMLs need to be selected for piping system with any of the
following characteristics:
1. Higher potential for creating a safety or environmental emergency in the event of
a leak.
2. Higher expected or experienced corrosion rates.
3. Higher potential for localized corrosion
4. More complexity in terms of fittings, branches, deadlegs, injection points, and
other similar items.
5. Higher potential for corrosion under insulation (CUI).
-
7/27/2019 Final Report Practical
30/59
30
Fewer TMLs can be selected for piping systems with any of the following three
characteristics:
1. Low potential for creating a safety or environmental emergency in the event of a
leak.
2. Relatively noncorrosive piping systems.
3. Long, straight-run piping systems.
TMLs can be eliminated for piping system with either of the following two
characteristics:
1. Extremely low potential for creating a safety or environmental emergency in the
event of a leak.
2. Noncorrosive systems, as demonstrated by history or similar service, and system
not subject to changes that could cause corrosion.
Based on design code; we can calculate MAWP and MAWT. All of the
calculation will be calculated by Galiom which is the software for asset integrity
management. The data for design pressure, design temperature, quality factor, design code
and nominal wall thickness are mandatory for any tag that we want to select TML. The
main objective for all of this process is to know the remaining life. This remaining life can
be known by knowing the remaining wall thickness, MAWT, and corrosion rate. The datacan be seen from figure 7 and mark-up drawing from figure 8 below:

CHAPTER 5
CONCLUSION
5.1 Conclusion
This internship was very fruitful to me because I learn new concepts and new
ways of working. It was interesting to see how business works, how it is vital to spare
money and to make strategic choices. Moreover, I know the importance of inspection at
facilities. I was also given opportunity to involve with projects.
Concerning the project that I was involved with, it was interesting to discover the
concepts that I was taught in my engineering school such as statics, solid of mechanics,
material engineering and component design. The work in itself was also interesting in
different point of views. Handling the PFD, PNID and isometric drawing allows me to
learn more in oil and gas field. Also, another interesting part was that I started from
scratch. Indeed, I have to mark-up drawings to find critical location for corrosion.
Moreover, I learned to use Galiom to do analysis. Even though that was
something new for me, I was able use this software and could understand the functions of
-

this software. Thanks to the staff of AIM department that were willing to teach me the
steps to understand this software.
This internship was a great experience. It was a real pleasure to work with GL.
Carrying out this internship in multi-national company allows me to experience different
culture and faced the problem of living and working entirely in a non-native language,
English. I also had the opportunity to meet interesting people in and out of the office such
as engineer, software engineer, as well as other people not connected with science.
5.2 Recommendation
I was grateful to be able to gain internship in GL. However there is one
recommendation to make the internship program more challenging and more organized.
One suggestion to make the project more organized is to plan for the whole internship
programme for the interns. The interns can be more focus towards the assignment that
had given rather than just accepting any assignment.

1. To understand about AIM, RBI, MAWT, Remaining life and MAWP
2. To be able to familiar with B31.3 and ASME VIII and can state the right equation for anycomponents especially pipe, shell, head and nozzle.
3. To understand about the plant life cycle.
Significance of Study
1. AIM is very important because it is focused on the operating and technical integrity which
means is the facilities being operated, maintained and being inspected as required.
2. The ability to understand RBI will make a huge impact to develop cost-effective inspection and
maintenance programs that provide assurance of acceptable Technical Integrity, Reliability and
Availability.
3. MAWP & MAWT are important because these data can be used to maintain a minimum integrity
level so the pipeline is operated safely and economical.

4. By knowing plant life cycle, we can manage the integrity of an oil & gas facility that needs to
consider the fundamental performance of materials in the oilfield environment in addition to
the economics of the oil industry and local operations and acceptable.
Answer
Asset Integrity Management
An asset has integrity when it performs as specified and is being operated and maintained as specified
so that the Risk to People, Environment, Assets and Company Reputation arising from its failure
is As Low As Reasonably Practicable.
Risk Based Inspection
The application of Risk Analysis principles to develop and manage inspection programs for plant
equipment.
Risk is the potential consequence based on a specific Hazard or Danger driven by its individual
probability of occurrence.
Minimum allowable wall thickness
The minimum required thickness, including mechanical, corrosion, and erosion allowances for wall
thickness.
Wall Thickness is a value that indicates the thickness of the tubing wall. It may remain unchanged as the
outside diameter and inner diameter change.

39/59
39
Remaining Life
The prediction of the occurrence of failure events for process equipment based on a clear definition of
load history, damage accumulated to date, projected operations and material properties.
Maximum Allowable Working Pressure
A maximum gauge pressure permissible by an equipment/device (at coincident temperature specified
for that pressure) and is governed by code i.e. ASME, JIS,GB, etc.
Formula
Straight Pipe according to B31.3
tm = t + c
tm = minimum required thickness, including mechanical, corrosion, and erosion
allowance
t = pressure design thickness, as calculated for internal pressure or as
determined for external pressure
-
7/27/2019 Final Report Practical
40/59

c = the sum of the mechanical allowances (thread or groove path) plus
corrosion and erosion allowances. For threaded components, the nominal
thread depth (dimension h of ASME B1.20.1, or equivalent) shall apply.
For machined surfaces or grooves where the tolerance is not specified, the
tolerance shall be assumed to be 0.5 mm in addition to the specified depth
of the cut.
Straight Pipe Under Internal Pressure
For t < D/6, the internal pressure design thickness for straight pipe shall be not less than that calculated
in these equations:
P = internal design gage pressure
-
7/27/2019 Final Report Practical

41
d = inside diameter of pipe. For pressure design calculations, the inside
diameter of the pipe is the maximum value allowable under the purchase
specification.
D = outside diameter of pipe as listed in tables of standards or specifications
or as measured.
E = quality factor from Table A-1A or A-1B (pages 231&232)
S = stress value for material from Table A-1 (pages 182)
For t D/6 or for P/SE > 0.385, calculation of pressure design thickness for straight pipe requires special
consideration of factors such as theory of failure, effects of fatigue, and thermal stress.
Y = coefficient from Table 304.1.1, valid for t < D/6 and for materials shown.
The value of Y may be interpolated for intermediate temperatures.
For t D/6,

Project Background
The Balal Field is located in the Iranian Sector of the Persian Gulf, at approximately 100 km to
the south-west (SW) of lavan island at a geographic location approximately 2619 N,
5232 E, in a water depth of approximately 66 m.
Introduction
The Balal Field is intended to drill 5 wells to produce from this interval at an initial total
production rate of 40,000 BOPD. Water injection will ultimately be required for pressure
maintenance and 5 injection are planned. The key design production rate is as follows:
Maximum crude oil production : 40,000 STBOPD
Maximum produced water rate : 33,000 BWPD
Maximum injection water rate : 50,000 BWPD Maximum total produced fluid rate : 45,000 BFPD
The development plan is based on a central complex comprising a combined Process and Living
Quarters (PLQ) platform, a single 16 slot drilling/wellhead platform (WHP) and a flare
tower, all bridge linked.
