CHAPTER ONE
1.0 INTRODUCTION
The
student industrial Work Experience Scheme (SIWES) was established by the
industrial Training Fund in (ITF) 1973 to enable students of tertiary
institution have basic technical knowledge of industrial works base on their
course of study before the completion of their program in their respective
institutions. The scheme was designed to expose students to industrial
environment and enable them develop occupational competencies so that they can
readily contribute their quota to national economic and technological
development after graduation.
The Student Industrial Work-Experience Scheme
(SIWES) is a planned and supervised training intervention based on stated and
specific learning and career objectives, and geared towards developing the
occupational competencies of the participants. It is a programme required to be
undertaken by all students of tertiary institutions in Nigeria pursuing courses
in “specialized engineering, technical, business, applied sciences and applied
arts” (ITF, 2004a).
Industrial
training fund in its policy statement No.1, published in 1973, inserted a
clause dealing with the issue of practical skills among locally trained
professionals. Section 15 of the policy statement states inter-alia, that “Great emphasis will be placed on
assisting certain products of post secondary school system to adopt or
orientate easily to their possible post graduate job environment.
The scheme exposes
students to industry based skills necessary for a smooth transition from
classroom to the world of work. It affords student of tertiary institutions the
opportunity of being familiarized exposed to the needed experience in handling
machinery and equipment which are not available in the education
institute.
1.1 Nature
and Scope of Students Industrial Work Experience Scheme (SIWES)
Practical knowledge relates to
doing. According to Ochiagha (1995) practical knowledge is learning without
which mastery of an area of knowledge may be too difficult to achieve.
Practical knowledge involves developing skills through the use of tools or
equipment to perform tasks that are related to a field of study.
No society can achieve meaningful
progress without encouraging its youth to acquire necessary practical skills.
Such skills enable them to harness available resources to meet the needs of
society. It was against this background that SIWES, otherwise referred to as
Industrial Training (IT), was introduced in Nigerian tertiary institutions.
SIWES is a skill development
program designed to prepare students of universities,
polytechnics/monotechnics, and colleges of education for transition from the
college environment to work (Akerejola 2008). Oyedele (1990) states that work
experience are an educational program in which students participate in work
activities while attending school. This work experience program gives students
the opportunity to be part of an actual work situation outside the classroom.
SIWES is a cooperative industrial internship program that involves institutions
of higher learning, industries, and the federal government of Nigeria,
Industrial Training Fund (ITF), Nigerian Universities Commission (NUC) and
NBTE/NCCE in Nigeria. Students that participate in this work experience program
include those studying library science, engineering, vocational, technological,
and related courses in institutions of higher learning. SIWES forms part of the
approved minimum academic standards in these institutions. SIWES is a core
academic requirement carrying four credit units. This requirement must be met
by all students in library and information science before graduation. It is
also compulsory at National Diploma (ND) level and is scheduled in the NBTE
curriculum. The training program is undertaken in the third year of a four-year
degree program.
Eze (1998) points out that
government has recognized the importance of SIWES through the establishment of
the Industrial Training Fund (ITF). The ITF was established in 1971 and was
charged with human resources development and training. Following the
establishment of ITF, SIWES commenced in 1974 with the aim of making education
more relevant and to bridge the yawning gap between the theory and practice of
engineering, technology, and science-related disciplines in tertiary
institutions in Nigeria. The specific objectives of SIWES were
summarized by the federal government in its Gazette of April, 1978 as
follows:
- To provide an avenue for students in
institutions of higher learning to acquire industrial skills and
experiences in their course of study
- To provide students with an opportunity to
apply their knowledge in real work and actual practice.
- To make the transition from school to the
world of work easier and to enhance students contacts for later job
placement.
It is obvious that the reasons
that led to the inception of the program some decades ago are today even more
relevant due to rapid technological development, especially as it concerns
Petroleum Engineering.
1.3 THE NEED FOR INDUSTRIAL TRAINING
Theoretical knowledge
alone would not usually prepare an educated person for the world of work. The
worker or productive individual must not only be knowledgeable but must also be
versatile in the application of skills to perform defined jobs or work.
The reality of the foregoing fact can be illustrated by using a simple analogy. While it is possible for someone to learn and imbibe all the available information on driving a car in the classroom, it is unlikely that the individual would, based on this knowledge alone, be able to drive a car at the first opportunity. On the other hand, someone else without the theoretical information on how to drive a car, on being told and shown what to do, followed by hands-on practice and supervision by an instructor, would at the end of the day be able to drive a car successfully. Of course, someone who has been exposed to both the theoretical underpinnings of driving a car and the hands-on experience of doing so would and should be a better driver! (Mafe, 2009).
The reality of the foregoing fact can be illustrated by using a simple analogy. While it is possible for someone to learn and imbibe all the available information on driving a car in the classroom, it is unlikely that the individual would, based on this knowledge alone, be able to drive a car at the first opportunity. On the other hand, someone else without the theoretical information on how to drive a car, on being told and shown what to do, followed by hands-on practice and supervision by an instructor, would at the end of the day be able to drive a car successfully. Of course, someone who has been exposed to both the theoretical underpinnings of driving a car and the hands-on experience of doing so would and should be a better driver! (Mafe, 2009).
Consequently, there are two basic forms of learning - education and training – both of which are indispensable to the productive world of work and the functioning of society today. In the illustration given above, the first individual had abundant education on how to drive a car; the second individual had received adequate training on how to drive a car; the third individual had the advantage of being able to combine theoretical knowledge with practical skills to become a better driver.
1.4 BENEFITS
OF INDUSTRIAL TRAINING FOR THE STUDENTS AND STAFFS
The major benefits accruing
to students who participate conscientiously in industrial training are the
skills and competencies they acquire. These relevant production skills (RPSs)
remain a part of the recipients of industrial training as life-long assets
which cannot be taken away from them. This is because the knowledge and skills
acquired through training are internalised and become relevant when required to
perform jobs or functions (Mafe, 2009).
Several other benefits can accrue to students
who participate in industrial training. These include the following:
• Opportunity for students to blend theoretical knowledge acquired in the classroom with practical hands-on application of knowledge required to perform work in industry.
• Exposure of students to the environment in which they will eventually work, thereby enabling them to see how their future professions are organised in practice.
• Minimization of the bewilderment experienced by students, particularly those from a non-technological background, pursuing courses in science, engineering and technology with regard to different equipment, processes, tools etc. available in industry.
• Opportunity for students to blend theoretical knowledge acquired in the classroom with practical hands-on application of knowledge required to perform work in industry.
• Exposure of students to the environment in which they will eventually work, thereby enabling them to see how their future professions are organised in practice.
• Minimization of the bewilderment experienced by students, particularly those from a non-technological background, pursuing courses in science, engineering and technology with regard to different equipment, processes, tools etc. available in industry.
• Enabling SET students appreciate work methods and gain experience in handling equipment and machinery which may not be available in their institutions.
• Preparing students to contribute to the productivity of their employers and national development immediately after graduation.
• Provision of an enabling environment where students can develop and enhance personal attributes such as critical thinking, creativity, initiative, resourcefulness, leadership, time management, presentation skills and interpersonal skills, amongst others.
• Preparing students for employment and making the transition from school to the world of work easier after graduation.
• Enhancing students’ contacts with potential employers while on training.
• Enabling students bridge the gap between the knowledge acquired in institutions and the relevant production skills (RPSs) required in work organizations.
• Making SET students appreciate the role of their professions as the creators of change and wealth and indispensable contributors to growing the economy and national development.
CHAPTERN TWO
2.0 INTRODUCTION
This chapter covers my
experience and what I learnt during my Industrial Training period in areas such
as Health Safety and Environment (HSE) .Its main focus is on the proper use of
personal protective equipment (PPE)
2.1 HEALTH, SAFETY AND ENVIRONMENT
Health, safety and Environment (HSE) departments also called
SHE or HSE departments, are entities commonly found within
companies that consider environmental protection, occupational health and
safety at work as important as providing quality products, and which therefore
have managers and departments responsible for these issues. EHS management has
two general objectives: prevention of incidents or accidents that might result
from abnormal operating conditions on the one hand and reduction of adverse
effects that result from normal operating conditions on the other hand.
For example, fire, explosion and release of harmful
substances into the environment or the work area must be prevented. Also action
must be taken to reduce a company’s environmental impact under normal operating
conditions (like reducing the company’s carbon footprint) and to prevent
workers from developing work related diseases. Regulatory requirements play an
important role in both approaches and consequently, EHS managers must identify
and understand relevant EHS regulations, the implications of which must be
communicated to top management (the board of directors) so the company can
implement suitable measures.
2.2 HAZARDS
A hazard is a situation that poses a level of threat
to life, health, property, or environment. Most hazards are dormant or
potential, with only a theoretical risk of harm; however, once a hazard becomes "active",
it can create an emergency situation. A hazardous situation
that has come to pass is called an incident. Hazard and possibility
interact together to create risk.
2.3 MODES OF A HAZARD
Hazards are sometimes classified into three modes;
- Dormant—the situation presents a
potential hazard, but no people, property, or environment is currently
affected. For instance, a hillside may be unstable, with the potential for
a landslide,
but there is nothing below or on the hillside that could be affected.
- Armed—People, property, or
environment is in potential harm's way.
- Active—a harmful incident
involving the hazard has actually occurred. Often this is referred to not
as an "active hazard" but as an accident, emergency,
incident, or disaster.
2.4 TYPES OF HAZARD
Hazards are generally labeled as one of five types:
Ø Physical hazards are
conditions or situations that can cause the body physical harm or intense
stress. Physical hazards can be both natural and human made elements.
Ø Chemical hazards are
substances that can cause harm or damage to the body, property or the
environment. Chemical hazards can be both natural and human made origin.
Ø Biological hazards are
biological agents that can cause harm to the human body. These some biological
agents can be viruses, parasites, bacteria, food, fungi, and foreign toxins.
2.5 CLASSIFICATION OF HAZARDS
By its nature, a hazard involves something that
could potentially be harmful to a person's life, health, property, or the
environment. One key concept in identifying a hazard is the presence of stored
energy that, when released, can cause damage. Stored energy can occur in many
forms: chemical, mechanical, thermal, radioactive, electrical, etc. Another
class of hazard does not involve release of stored energy; rather it involves
the presence of hazardous situations. Examples include confined or limited
egress spaces, oxygen-depleted atmospheres, awkward positions, repetitive
motions, low-hanging or protruding objects, etc.
There are several methods of classifying hazard,
but most systems use some variation on the factors of "likelihood" of
the hazard turning into an incident and the "seriousness" of the
incident if it were to occur.
A common method is to score both likelihood and
seriousness on a numerical scale (with the most likely and most serious scoring
highest) and multiplying one by the other to produce a comparative score.
2.6 PRIORITIZATION OF HAZARDS
Hazards can be identified and prioritized using the SMUG model. The SMUG
model provides a means for prioritizing hazards based on the risk they present
during an emergency. The SMUG model stands for Seriousness, Manageability,
Urgency, and Growth.
2.7 ACCIDENTS
An accident or a mishap is an incidental and
unplanned event or circumstance, often with lack of intention or necessity. It usually implies a generally
negative outcome which might have been avoided or prevented had circumstances leading up to the accident been
recognized, and acted upon, prior to its occurrence. Injury prevention refers to activities designed to
foresee and avoid accidents.
Accidents of particularly common types (crashing of automobiles, events causing fire, etc.) are
investigated to identify how to avoid them in the future. This is sometimes
called root
cause analysis, but
does not generally apply to accidents that cannot be deterministically predicted. A root cause of an uncommon and purely random accident may never be identified, and thus future similar
accidents remain "accidental."
2.8 TYPES OF ACCIDENTS
Physical and non-physical
Ø Physical
examples of accidents include unintended collisions or falls, being injured by
touching something sharp, hot, or electrical, or ingesting poison.
Ø Non-physical
examples are unintentionally revealing a secret or otherwise saying something incorrectly, forgetting an
appointment, etc.
2.9 SAFETY EQUIPMENT
A critical part of welding safely is having,
and knowing how to use, the correct safety equipment for the job. Here are some
typical items that are required for welding safely.
§ Welding shield (hood). This is
the mask which is worn to protect the person welding from the bright flash of
the arc, and from sparks being thrown during welding. Standard arc welding
lenses are tinted very darkly, since exposure to the arc flash can cause flash
burns to the retina of the eye.
§ Welding gloves. These are special, insulated
leather gloves that reach above the wrists, and protect the hands and lower
arms of the welder. They also provide limited protection from accidental shock
if the person welding comes into contact with the electrode accidentally.
§ Welding leathers. This is an apron like leather
jacket that covers the shoulders and chest of the welder, used for overhead
work where sparks might ignite the welder's clothing, or cause burns.
§ Work boots. The person welding should weara
boot to prevent sparks and hot slag from burning his feet. These boots should
have insulating soles made from a material which does not melt or burn easily.
2.10 Tool Box Meeting
This is a daily routine
activity in the company .It usually start by 7:45 am in the morning and can
last for 15 minutes.This is when the activity for the day will be discussed and
then appropriate guidelines and working procedure discussed. After the Tool Box
meeting, work commences by 8 am for the
day.
CHAPTER THREE
PIPELINE
LEAK DETECTION
PIPELINE
HYDRO TEST
Hydrostatic
(Hydro) Testing is a process where components, such as piping or pressure vessels are tested for strength and leaks by
filling the equipment with pressurized liquid. For pipelines, hydro tests are conducted while the
pipeline is out of service. All oil and/or natural gas is typically vented off,
and the line is mechanically cleaned prior to testing.
Hydrostatic testing works by completely
filling the component with liquid (usually, but not always, water), until a
specific pressure is reached. The hydro test pressure often exceeds the
designed working pressure of the equipment, sometimes by over 150%, depending
on the exact regulations and code requirements, as applicable. The pressure is
then held for a specific amount of time to inspect visually for leaks. The
visual inspection can be enhanced by applying either tracer or fluorescent dyes
to the liquid, as required or needed.
Hydrostatic testing is often required as a
final proof test after repairs are completed and equipment is returned to
service. While it can tell you whether or not leaks are present, a hydrostatic
test does not necessarily ensure the integrity of the component beyond the time
period of the actual test. On-going equipment integrity is best managed by an
effective, integrated fixed
equipment mechanical integrity (FEMI) program.
There are two additional methods of
hydrostatic testing: water jacket testing and the direct expansion method.
These are more often used for cylinders or vessels.
- With water jacket testing, the vessel to be examined is
filled with water, after which it is placed in a sealed container which is
itself filled with water and connected to a calibrated gas tube. It is at
this point that the vessel is pressurized for a period of time before
being subsequently depressurized. Pressurizing the vessel forces water out
of the test jacket and into the tube. Operators can then determine how
much the vessel expanded. This method does cause some slight, yet
permanent stretching to the vessel.
- With
the direct
expansion method, the
vessel being examined is completely filled with water. Then additional
water is pumped in until it reaches the test pressure. The amount and
weight of the water forced into the vessel, along with the amount not
expelled from the vessel upon the release of the pressure allows the
inspector to determine how much the vessel expanded.
Hydrostatic testing can be used to examine
many different types of equipment, including pipelines, fire extinguishers, storage tanks, and gas cylinders. It is particularly
useful for pipelines in situations where the use of inline inspection tools are not feasible.
Prior to conducting a hydrostatic test, one
should consider the specific gravity and chemistry of the hydro test fluid both
in terms of loads and corrosivity (e.g., chloride content of water), and how
this may impact the equipment. For example, some equipment foundations and
piping supports may not be designed to handle the loads. When hydrostatic loads
are unacceptable, alternative test methods should be considered such as
pneumatic testing or other gas leak testing. When using gasses (e.g., air or
nitrogen), special caution should be paid to safety as gas pressurization
results in significantly higher amounts of stored energy in the test subjects,
which can result in catastrophic failures. It is best to use a customized
procedure, created by competent personnel, for this type of testing.
CHAPTER FOUR
4.1 EQUIPMENT USED IN PIPELINE LEAK DETECTION
Hydrostatic testing of systems or components is most times referred to
as “H” pressure tests. These tests of piping systems should be at a pressure of
135 percent above the maximum system design pressure, but in no case less than
50 psi. The line drawing in fig 1 shows a simple hydrostatic test setup and
associated equipment.

Fig 1
Hydrostatic testing of piing systems or components
should be conducted in an area that can bbnnbnnnnnnnnnnnbe secured from all
distractions.
The area should also provide the operator
protection in event of component failure. When hydrostatic testing the piping
system,set the equipment in an area that can be secured from all unwanted
distractions.
The equipment required for hydrostatic testing
includes a pump, two pressure gauges, two relief valves, a cutoff valve, blank
flanges, gaskets and clamps.
PUMPS: There is no specific requirements for the type of pump to be used for
hydrostatic testing. The pump must be large enough to deliver the required
pressure and water volume to the piping
system being tested. Pneumatic pumps are the most common type of pump used for
hydrostatic testing .
Fig 2 and 3 show different pumps that can be
used during hydrostatic testing.

Fig 2

Fig 3
PRESSURE
GAUGES:When performing
hydrostatic tests, use two independent
pressure gauges. These two gauges
will indicate actual hydrostatic test pressure. One of the two pressure will be
the master gauge and the other will be the backup gauge. The master test gauge
readings are used as the true hydrostatic test pressure throughout the test.
·
Master Gauge: Master gauges are used to indicate the actual hydrostatic test
pressures. The scale range of the master test gauge are usually greater than
the maximum test pressure but should not
be more than 200 percent of the maximum test pressure. Master test gauges shall
have a valid caliberation label according to standard.
·
Backup Gauge: A backup gauge is used to check and certify the accuracy of te master
test gauge. Just like the master gauge, the backup gauge is also in line to the
actual test pressure, but should not exceed 200 percent of the maximum test
pressure. Backup test gauges shall also have a valid caliberation according to
standard.
·
Relief Valves: Relief valves provide for over pressure protection of the system or
component, equipment and also the safety of the personnel.
The fig 4 below shows a hydrostatic gauge for measuring pressure during
leak detection using hydrostatic testing method.

4.2 NON-DESTRUCTIVE
TESTING OF OIL AND GAS PIPELINES
Non-destructive testing (NDT) is common testing techniques in
engineering used in the oil and gas industry the properties of a material,
component or system without damaging it. This can also be called
Non-destructive inspection (NDI). This is because NFDT does not permanently
destroy the material being tested, hence it saves both time and money in the
cause of engineering testing.
Popular NDT methods used in the oil and gas industry includes;
Ø Ultrasonic magnetic –particle testing,
Ø Remote
Visual Inspection (RVI)
Ø Eddy-current testing
Ø Low coherence interferometry
NDT can be applied in the following field of engineering;
Ø Petroleum engineering
Ø Forensic engineering
Ø Mechanical engineering
Ø Electrical engineering
Ø Civil engineering
Ø Medicine such as in;
·
Medical
imaging
·
Echocardiography
·
Medical
ultrasonography
·
Digital
radiography
Ø Systems engineering and
Ø Aeronautical engineering.
4.3 Engineering applications of NDT in the oil
and gas industry
NDT is used in so many oil and gas settings that covers a wide range of
industrial activities, with new NDT methods being developed at an advanced speed.
NDT methods are usually applied in industries where a failure of a component
would cause a lot of hazard or economic loss, such as in transportation
equipment, pressure vessels, building structures, piping systems and in
hoisting equipment.
4.4 Pipeline weld testing
In pipeline engineering, welds are used commonly to join two or more
metals parts together. This is because these connections may encounter loads
and fatigue during the material lifetime. What this implies is that there is a
chance that they may fail if not created to proper specifications. For example
, the base metal must reach a certain
temperature during welding process, must cool at specific rate, and must be
welded with compatible materials or the joint may not be strong enough to hold
the parts together, or cracks may form in the weld causing it to fail. The
welding defects such as lack of fusion of the weld to the base metal, cracks or
porosity inside the weld, and variations
in weld density could cause the pipeline to break.
To avoid this breakage, these welds may be tested may be tested using
Non-destructive techniques such as industrial radiography, x-rays, ultrasonic
testing or by magnetic particle inspections.
In a proper weld, these tests would indicate a lack of cracks in the
radiograph, show clear passage of sound through the weld and back or indicate a
clear surface without penetrants captured in cracks.
4.5 Levels of certification
Most pipeline
Radiographic personnel certification schemes above specify three
"levels" of qualification and/or certification, usually designated as
Level 1, Level 2 and Level 3.
The roles and responsibilities of personnel in
each level are generally as follows (there are slight differences or variations
between different codes and standards.
Ø Level
1
are technicians qualified to perform only specific calibrations and tests under
close supervision and direction by higher level personnel. They can only report
test results. Normally they work following specific work instructions for
testing procedures and rejection criteria
Ø Level
2
are engineers or experienced technicians who are able to set up and calibrate
testing equipment, conduct the inspection according to codes and standards
(instead of following work instructions) and compile work instructions for
Level 1 technicians. They are also authorized to report, interpret, evaluate
and document testing results. They can also supervise and train Level 1
technicians. In addition to testing methods, they must be familiar with
applicable codes and standards and have some knowledge of the manufacture and
service of tested products.
Ø Level
3
are usually specialized engineers or very experienced technicians. They can
establish Radiographic techniques and procedures and interpret codes and
standards. They also direct the laboratories and have central role in personnel
certification. They are expected to have wider knowledge covering materials,
fabrication and product technology.
4.6 OIL AND
GAS PIPELINE RADIOGRAPHIC TESTING
Pipeline
radiography is the use of ionizing radiation to
view pipelines in a way that cannot be seen otherwise. radiography's purpose is
strictly viewing. Industrial radiography has grown out of engineering, and is a
major element of nondestructive testing. It is a method of inspecting materials
for hidden flaws by using the ability of short X-rays and gamma rays to
penetrate various materials. One of the major ways to inspect materials for
flaws is to utilize X-ray computed tomography.
In
Radiography Testing the test-part is placed between the radiation source and
film (or detector). The material density and thickness differences of
the test-part will attenuate (i.e. reduce) the penetrating radiation
through interaction processes involving scattering and/or absorption. The differences
in absorption are then recorded on film(s) or through an electronic means. In
industrial radiography there are several imaging methods available, techniques
to display the final image, i.e. Film Radiography, Real Time Radiography (RTR),
Computed Tomography (CT), Digital Radiography (DR), and Computed Radiography
(CR).
There
are two different radioactive sources available for industrial use; X-ray
and Gamma-ray. These radiation sources use higher energy level, i.e. shorter
wavelength, versions of the electromagnetic waves. Because of the radioactivity
involved in radiography testing, it is of paramount importance to ensure
that the Local Rules is strictly adhered during operation.

Applicability
Radiographic testing is used extensively
on castings and weldments. Radiography is well suited to the testing of
semiconductor devices for cracks, broken wires, unsoldered connections, foreign
material and misplaced components. Sensitivity of radiography to various types
of flaws depends on many factors, including type of material, type of flaw and
product form. Both ferrous alloys can be radio graphed, as can non-metallic
materials and composites.
Limitations
Compared to other NDT methods,
radiography is expensive. Relatively large capital costs and apace allocations
are required for a radiographic laboratory. Field testing of thick sections is
a time consuming process. High activity sources require heavy shielding for
protection of personnel. Tight cracks in thick sections usually cannot be
detected at all, even when properly oriented. Minute discontinuities such as
inclusions in wrought material, flakes, micro- porosity and micro-fissures
cannot be detected unless they are sufficiently segregated to yield a
detectable gross effect. Laminations are impossible to detect with radiography,
because of their unfavorable orientation. Laminations do not yield differences
in absorption that enable laminated areas to be distinguished from limitation
free areas.
It is well known that large doses of
X-rays or gamma rays can damage skin and blood cells, can produce blindness and
sterility, and in massive doses can cause severe disability or death.
Protection of personnel not only those engaged in radiographic work but also
those in the vicinity or radiographic testing is of major importance. Safety
requirements impose both economic and operational constraints on the use of
radiography for testing.
4.7 Employees’ Training, qualifications and
certifications for radiographic testing
Successful and careful application of Radiography depends heavily on
personnel training, experience and integrity. Personnel involved in
Radiographic testing and interpretation of results should be certified and in
most oil and gas industries, certification is usually enforced by law or by the
applied standards usually according to international Standard Organizations
(ISO).
The terms usually associated with this includes;
·
Certification: Procedure used by the certification body to confirm that the
qualification requirements for radiography has been fulfilled, leading to the
issuing of certificates.
·
Qualification:Demonstration of
physical attributes, knowledge, skill, training and experience required to
properly perform radiographic tasks
·
Training
Radiographic
testing training is provided for people working in many oil and gas industries.
It is generally necessary that the candidate successfully completes a
theoretical and practical training program, as well as have performed several
hundred hours of practical application of this particular method they wish to
be trained in. At this point, they may pass a certification examination. While
online training has become more popular, many certifying bodies will require
additional practical training.
4.8 Certification schemes
There are two approaches in personnel certification;
1.
Employer Based Certification: Under
this concept the employer compiles their own Written Practice. The
written practice defines the responsibilities of each level of certification,
as implemented by the company, and describes the training, experience and
examination requirements for each level of certification. In industrial sectors
the written practices are usually based on recommended practice.
2. Personal
Central Certification: The concept of central certification
is that a Radiographic test operator can obtain certification from a central
certification authority that is recognized by most employers, third parties
and/or government authorities.
INTRODUCTION TO LIFTING SYSTEM
These are various means or system by which lifting
operations are usually
carriedout especially during fitting of the pipes
orduring loading for transportation of the pipes, etc.
The lifting system is very essential in the oil and
gas pipeline welding industries as most of the materials used are usually very
heavy, hence cannot easily be carried by humans. Likewise the lifting system
has a critical and important general use in the oil and gas industries.
TYPES OF LIFTING EQUIPMENT AND DEVICES
1. Cranes;

The crane system is of various types, they include;
Ø Rough-terrain crane; this
type of cranes uses very strong and massive tires and can be used to work in
places that are rough due to the fact that it can withstand the harsh
environment.
Ø The crawler; this kind of crane works on a
steel track or terrain.
Ø The stationed crane; this
kind of cranes are usually non-mobile, that is it is immoveable.
2. The chain blocks; this is a lifting device for
carrying heavy loads efficiently.it comes in various forms based on the
capacities, such as 1.5tons,5tons,10tons,etc
CHAPTER
FIVE
5.1 Conclusion
SIWES plays a
significant role in human resource development in Nigeria. Petroleum
Engineering developments have put more pressure on the SIWES program to help
students develop new skills. Students should be aware of what the present
society holds for them and adapt accordingly. This can only be facilitated by
Petroleum Engineering lecturers and practitioners, with adequate provision
of required facilities. This emphasizes
the need to expose trainees to industrial facilities. All depends on the
competence of the educators and practitioners in industrial skills. This is a
challenge to all stake holders in petroleum engineering human resources
development.
5.2
Recommendations
I
strongly recommend the following;
1.
The ITF should ensure that the backlog in payment of student allowances is
cleared urgently to remove the negative image being created for SIWES.
2. There is a need for closer monitoring of the SIWES function and activities in tertiary institutions by the Supervising agencies (NUC, NBTE and NCCE) to ensure that the scheme is properly implemented.
3. The supervising agencies in collaboration with institution, should evolve minimum standards in respect of SIWES and develop, monitor and review job specifications to guide the training of students for all SIWES-approved programmes.
4. The cooperation of employers in providing places for industrial attachment of students can be enhanced by more stringent penalties for defaulters.
