Introduction & The Company

1. Introduction

As an Engineering student in Prince Mohammad bin Fahd University at the

Electrical Engineering Department, I am required to do summer training at a

company in the Kingdom of Saudi Arabia or abroad. The summer training

program is an eleven weeks training. I have taken my summer training in Saudi

Aramco Company working for Consulting Services Department/Electrical

Engineering Division from Jun 16 to Sept 5, 2012

In this period of training tried to gain field experience in the areas related to

the electrical engineering. Also, I tried to look for new technologies and tools

available in area of electrical engineering. I applied theoretical engineering skills

into real world engineering problems. In Addition, I learned how to deal with

engineering project and technical problem solving. I got familiar with

organizational skills, work ethics, teamwork skills, and time management in a

field environment.

2. The Company

Aramco was established in 1933. It was the Arabian American Oil Company

until 1988 it was owned by the government and became Saudi Arabian Oil

Company. Aramco kept growing to be the most valuable company in the world. It

manages over 100 oil and gas fields and produces 3.4 billion barrels annually.

Consulting Services Department (CSD) focuses on safety, research and

technology, standards optimization, capital programs support, and operation

support and Improvement. CSD consists of four divisions; Materials Engineering

and Corrosion Control Division, Mechanical Engineering Division, Rotating

Equipment and Civil Engineering Division and Electrical Systems Division (ESD).

ESD consists of three units, Electrical Equipment Unit (EEU), Power Systems

Unit (PSU), Direct-Current Systems and Cathodic Protection Systems Unit

(DCSU). ESD provides consultation in these four fields.

Introduction & The Company

Page 8 of 43


Activities & Responsibilities

The objective of my summer training with CSD is to familiarize me with

industrial application of electrical engineer in the area of power system design,

analysis, and equipment. They planed me a program that include safety

orientation, site visits, and getting introductory sessions on different major of

electrical equipments and power systems. My Supervisor is Salh ali assigned me

a mentor. My mentor is Odah Al Shahrani, who is an engineer (II), is working

with power systems and substation equipment group. Odah introduced me to the

department and the electrical systems division and gave me orientation on the

safety at office and plants.

My plan with ESD included working with the eight specialties that the division

have. The specialties are Cables and lighting, substation equipment, motors and

generators, cathodic protection, UPS and DC systems, power system, design and

studies, and substation automation.

3. Activities and responsibilities

3.1 Al-Oalyan Workshop Visit

I went with Mr. Hussian from Electrical Equipment Unit, motors and

generators group, to inspect a submersible pump from Khursaniyah Gas Plant.

The pump was tripped due to a ground fault immediately after starting it. The

pump was inspected and found that the motor side was having sort of “burn” or

heat exposed to the majority of the winding. Signs of carbon and discoloration

were observed on the winding, aside from the stator but not the rotor.

Fig.1 (Pictures Motor and the burn on the winding)

Page 9 of 43



Khursaniyah Gas Plant found that:

1. No Failure of the seal – Mechanical or cable Seal – found

2. Bearing was found moving freely

3. Greasing was in good condition

4. Lubricant oil was found clean

5. Signs of carbons found around the winding of the motors

6. 2/3 windings were found in a bad condition - carbonized and insulation

damage

7. The shaft was intact

8. Discoloration was found on the stator segments along with the damaged

windings

9. The failure occurred on the motor from the pump side only

At the workshop we saw the motor and we inspected it to see what could

cause the ground fault. The burn can be seen clearly on the winding there was a

sensor but we were not sure of it, is it for temperature or for the flow. After the

inspection, we discussed the possibilities of causing the problem.

Note:

For motor’s data sheet, you can find it in Appendix A

3.2 WESCOSA Visit:

As a part of our summer training program with CSD, we had a site visit to

WESCOSA in Dammam in July 26, 2012. The purpose of this visit is to be familiar

with electrical equipments, transformers and switchgears, and the process of

manufacturing them. During this visit we got a quick overview about WESCOSA.

We had a presentation about WESCOSA transformers that meet the

requirements of Aramco. It follows SAES-P-121 and 16-SAMSS-536,531,534,533

in Aramco standards. They produce three types of transformers, Pole-Mounted,

Power Transformers and Pad-Mounted Three-Phase Distribution Transformers.

Page 10 of 43



First, the Pad Mounted Distribution Transformer is three phase, oil filled, and

serves underground distribution loads. Pad Mounted Transformers are available

in two constructions live front construction, or dead front construction. The

ratings of the transformer are From 45 – 1500 kVA. The high voltage taps are ±2-

2.5% from normal.

Fig.2a (Pad Mounted Transformer)

Second, the Pole Mounted Distribution Substation Transformer is designed

for continues operation and It cooled itself for tropical climates. Pole Mounted

Transformers are suitable for indoor and outdoor installation. The ratings of the

transformer are From 50 – 1500 kVA and the high voltage taps are ±2-2.5% from

normal.

Fig.2b (Pole Mounted Transformer)

Third, the Power Substation Transformers is used to provide electrical

services for distribution system. In power transformer, both primary and

secondary cables enter the transformer cable boxes from below. There are

different designs to meet both IEC and ANSI standards. The ratings of the

transformer are from 500 – 34500 kVA and the high voltage taps are ±2-2.5%

from normal

Page 11 of 43



Fig.2c (Power Transformer)

Process of transformer manufacturing:

The process of transformer manufacturing is done by several steps:

1. Winding

They wind three phase winding , one by one

The inner winding is the secondary, while the outer is the primary

At the secondary, after certain winding turns, they extract a voltage

tap

2. Shell Core

They mostly use steel core

They are made of laminated steel to reduce Eddy current losses in the

core

Then they set them inside the winding side by side

3. Bushings

They weld three bushings, each to the transformer tank , each

bushing is connected with a phase winding

4. Closing

They place the windings inside the tank

Each type of transformer has different tank shape

Also, they inject a nitrogen gas to protect the transformer from arc

flash

After that, they inject the oil into the transformer from an oil reservoir

Page 12 of 43



5. Testing

They do a test for both high voltage transformers and medium voltage

transformers

They have two testing areas for each type

Some of the testing they do are :

o They test the open circuit and short circuit to measure the

losses in the core and the winding

o They do a high voltage test to inspect the insulation between

the winding turns

Switchgear manufacturing process:

In the factory of switchgear, we have started with how they do the cover box

and where they cut, band and insulate the cupper plates. Also, we have seen how

they connect the circuit breakers as well as the wiring. Finally, they explained to

us how the test of switchgears is done. In addition we saw different types of

switchgears with respect to voltage, which are low, medium and high voltage

switchgears. At the end of our visit we have seen the control panels. These

control panels are used in low voltage applications as the panels used at homes.

Fig.2d (Switchgear & Control Panel)

Note:

WESCOSA prevents taken pictures in inside the factory. However, I took some

picture from the outside; you can find it in Appendix A

Also, you can find the report of the visit in Appendix B

Page 13 of 43



3.3 Motors:

During my summer training program with CSD, I took courses on motors

with Mr. Al-Ali. Also, I worked with the motors and I had an overview of their

function, types, and motors that Aramco uses. The main function of motors is to

convert electrical energy to mechanical and produce torque.

The operation of motors is based on three main principles. First, when the

electric current passes through a conductor, magnetic field is produced around

it. So, if the wire is wound around iron rod, the magnetic field will strengthened

and the rod will be magnetized. And, the magnetic field becomes stronger as the

turns of coil increases. Second, the direction of the current flow through coils

determines the location of the poles on the electromagnetic. Third, like poles,

such as two north poles repel each other. Unlike poles attract each other. So, if a

bar magnet is suspended between the ends of a horseshoe magnet, the bar

magnet will rotate until its north pole is opposite the horseshoe magnet's South

Pole.

Fig.3a (Magnetic Theory)

There are two types of motor, DC motors and AC motors. DC motors are used

where high torque and controlled speed over a wide range are needed. It

requires high level of maintenance. AC motors are usually used in industrial

applications.

There are three types of DC motors classified according to the type of

winding; Series-wound, Shunt-wound, and Compound-wound motor. In Series-

wound motor armature and field coils are connected in series. In Shunt-Wound

armature and field coils are connected in parallel. The Compound-wound motor

incorporates both Series-wound and Shunt-wound windings.

Page 14 of 43



The main two parts in typical DC motors are stator and rotor. Where stator is

the stationary part and rotor is the rotating portion of a DC motor. The stator

consists of the frame, filed winding, brush rigging, and brushes and end bells,

where the rotor is consists of the armature, commutator, and blower.

Fig.3b (Components of DC motor)

There are three type of three-phase AC motors; Squirrel-Cage Induction

Motor, Wound-Rotor Inductor Motor, and Synchronous Motor. Squirrel-cage

induction motor is the common of all AC motors and has the sample

construction.

The major components of squirrel-cage motor are; the stator, rotor, field coils,

and fan.

Fig.3c (Components of AC Squirrel-Cage Induction Motor)

Page 15 of 43



Fig.3d (Squirrel-Cage Rotor)

Fig.3e (Three-Phase Motor Winding)

The other type of AC motor is synchronous motor and it operates at constant

speed. The major components for Synchronous motor are; Stator, Laminated

Salient Pole, Solid Salient Pole Rotor, and Cylindrical Rotor. Synchronous motor

has different starting method. A three-phase current is supplied to stator

winding to produce magnetic field and direct current is supplied to rotor

winding to produce magnetic field with fixed polarities at each end.

3.4 Wasit Project Review:

I joined Mr. Abdulmohsun form PSU in reviewing the Wasit Cogeneration &

Steam Generation project on ETAP. Wasit Cogeneration & Steam Generation

consists of six generators. Four Combustion Gas Turbine Generators (CGTG),

each rated 148.954MW at 16.5kV. And, two Steam Turbine Generators (STG),

each rated 75MW at 13.8kV. The purpose of the electrical system studies is to

verify the design of the electrical system:

Main Equipment (generators, transformers, switchgear) sizes, ratings and

main parameters

Starting of largest motors

The review includes three parts load flow studies, short circuit studies, and

motor starting studies. For the load flow analysis we did three cases maximum

system voltage, normal system voltage, and minimum systems voltage. In all

cases we shall check the voltage level. For low voltage, the level shall be between

95-105% and for high voltage the level shall be between 97-105%

For the maximum case, it shall be feeding form two sides, all motor

disconnected, and the bus-tie breaker is open. For the normal case, it shall be

feeding from two sides, all loads are running, and the bus-tie breaker is normally

open. For the minimum case, it shall be feeding from one side, the bus-tie

breaker is close, and all loads are running.

For the short circuit analysis we shall assume the pre-fault to 102%. It shall

be feeding from one side and the bus-tie breaker is close. We shall fault all buses.

For the motor starting analysis, the minimum voltage level for the motor

terminal shall be not less than 85%. If utilization equipment modeled as lumped

Page 17 of 43



load at distribution bus, minimum voltage shall be not below 90%. We shall

check the largest motor in the system at starting.

There was a problem with the transformer voltage level and Mr. Konash

sends to them an email about it.

Major Tasks or Projects

4. Major tasks or projects

1.1 Meeting with Facilities Planning Department (FPD)

I joined a meeting with Mr. Abdulmohsun from Power System Unit (PSU) and

FPD. It was regarding a voltage drop caused by starting a large motor in Tanajeeb

The FPD brought three suggestions they want to discuss and review on ETAP:

1. Adjustable Frequency Drive (AFD)

2. Transfer the loads, which are affected by starting the motor, to another

bus

3. Static Var Compensator (SVC)

The Adjustable Frequency Drive (AFD) was the last choice that may use

because the cost of AFD is very high. Transfer the loads to another bus will not do

much change for the motor to start. But, it will improve the operation of the loads

as the motor start. Static Var Compensator (SVC) will improve the operation so

the motor can start by providing VAR reactive power. However, using the SVC

with loads are connected to the same bus of motor will be a problem to the

operation level of loads as the motor start (it will be less than 90%, NOT OK!).

However, the decision has not been taken yet.

1.2 Repairing Motor in Melssa Workshop:

I went to Melssa workshop with Mr. Al-Ali to inspect a motor. Then I attended

meeting in Melssa workshop to evaluate maintenance that the motor need. The

meeting was between Melssa, CSD, and MSSD. CSD motor specialist support is

required finding and evaluating the looseness of the Stator supports, Rotor pole

plat looseness, and Bearing housing tight on the bearing.

We have discussed during the meeting:

- The looseness of the Stator supports.

For the fingerplates, we need to apply the epoxy to fix the fingerplates. A

good indication, we have noticed in the fingerplates is that they are not

Page 21 of 43

The load should be more than 90% to justify the standard

The Motor should be more than 75% to start



broken so there should not be a major concern with fixing these

fingerplates with epoxy.

- Rotor pole plat looseness -which needs farther inspection as recommended

by CSD and MSSD QA to determine if need to install a new rotor kit.

The contractor should inspect the poles by removing the cover in order

to verify the cause of looseness and also the thickness of the cover should

be measured to verify if it meeting the original design thickness

- Bearing housing tight on the bearing – two options repair plan either to

machine

The ID or adding shim between the bearings spilt surface. If both options

do not work the bearing housing will be replaced with new one

The repair costs for the 2 options of repair the stator & rotor for subject motor

21000 hp sub-orders# 10749446 is as follow:

Conclusion

2. Conclusion

In this period of training I had a good chance to get field experience in the

areas related to Electrical Engineering. I opened my mind to new technologies

and tools available in industry. I had a chance to use my theoretical engineering

skills gained in academia into real engineering problems. Also, getting involved

in engineering project and technical problem solving helped me to use critical

thinking and teamwork strategies. Visiting factories and workshops helped me to

be familiar with the electrical equipments and the process of manufacturing.

Also, I had the chance to work with specialties and engineers and benefit from

their experiences.
