CE 1.2.5 My responsibilities throughout the project
I conducted micro simulations, process modeling as well as integration into development
of the electronics devices as well as products. I supervised as well as inspected the installation of
the floating suction and manual level indicator, water drain pipe and valve, improvement, testing
as well as operations of the electronics systems.I had helped in the development of the project’s
electrical components. This had been able to help the project to complete within the requirements
of the project. I had also helped in the designing of the electrical components for the project
which helped in the determination of the working process of the project.I developed the

maintenance of the power plant while the construction work was taken place. I also developed
the operating standards for both electrical as well as electronics systems with the equipment’s. I
investigated all the electronics failures as further it would become a big issue into the
construction work.
CE 1.3 Distinctive Activity
CE 1.3.1 Comprehending the theory of the project
I had conducted the construction work into design of a LFO farm tank into the Harriyah
power plant. I had involved into construction of tank 401 as well as tank 301. There was
installation of floating suction assemblies for used into horizontal/vertical, above/below of the
ground storage tanks where there is little contamination. As the fuel near the top is less contain
of water, therefore the floating suctions are being designed to float nearly the top of surface of
liquid. I had analysed that it provides with contamination free liquids. The main motive behind
design of floating suctions is for long as well as trouble free life. I had observed that it helps to
increase efficiency and reduce the maintenance of the filter separators. I had also installed a
manual level indicator of at least 0.75’’ size of pipe includes of isolation valves. It is mainly used
for lowering resistivity switching. I had also installed of valve which is the main part of the
construction work of farm tank. I had set the valves and sealed it for functioning at particular
start to discharge pressure based on the regulations of the power plant.
CE 1.3.2 Engineering knowledge and skills applied in the project
I have knowledge and skills to conduct of fabrication of the electronics equipment’s,
structural as well as pressure vessels. I had applied the skills of electrical engineering for the
designing of the components for the project which would help in the completion of the task

easily. The circuits and the systems required for the project had been studied and then used for
the project so that there can be minimum amount of risk related to the working process of the
parts. I have installed the floating suction and manual level indicator, water drain pipe as well as
valve. I have conducted of multidiscipline construction as well as commissioning of the LFO
farm tank. I have conducted of piling work with the hydraulic rotary rig. I have knowledge to
determine as well as calculate the surface area of the tank to determine the size of the valve and
total number of valve.
CE 1.3.3 Accomplishment and task performed
I had installed the valves into the storage tank helps to start to discharge the pressure.
Those values are started to open based on the pressure. When there is rise into the pressure, then
it continues to open in order to relieve the pressures. I had observed that when there is excess of
pressure into the container, then the valve will become to reseat. I was aware in the situation
when the valve discharges as well as pressures subside, then it will not reseat as per the design. I
had verified the local codes as pressure rating is required as some of the states required of high
highest working pressure vessel. The vapour safety valves are required to size in order to meet
with the project requirements as well as design criteria of the farm tank. I had calculated the
discharge rate for the pervaded sized tank based on the surface area of the provided tank design.
Based on the surface area of the farm tank, there is requirement of flow rating for safety relief
and it determines the sizing of the valve. Along with this I had also helped in the designing of
various circuits and equipment’s for the project which were installed alongside the required
components. I had also determined the total numbers of valves required for the construction. I
had taken the following parameters for the construction of the LFO farm tank 401 and tank 301
as follows:

a. Tank Filling Valve – 10”, 150# RF, Manual Gate Valve with Limit Switch
b. Tank Transfer Skid Valve – 8”, 150# RF, Manual Gate Valve with Limit Switch
c. Load/ Unload Skid Valve – 10”, 150# RF, Manual Gate Valve with Limit Switch
d. Tank Transfer Skid Valve – 10”, 150# RF, Manual Gate Valve with Limit Switch
e. Tank Valve – 18”, 150# RF, Manual Gate Valve with Limit Switch
f. Tank Valve – 18”, 150# RF, Manual Gate Valve without Limit Switch
g. Tank Spare Valve – 18”, 150# RF, Manual Gate Valve without Limit Switch – Bolted with
Blind Flange.
The technical specification of the project is that it is based on design and size of water
drain system for LFO tank. The system is suitable for draining of the water collected at roof
sump throughout the shell nozzle near the bottom of tank. At designing of the water drain
system, the roof is at low leg height difference between the outlet of sump drain of the roof and it
is discharged at the outlet to be considered as 1.5m. The water drain system consists of
equipments which are tested for operations into petroleum storage tanks.
CE 1.3.4 Identified issues and their solutions
1.3.4.1 Issues
I had faced inspection issues of the existing aboveground of the farm tank. Inspection,
repair as well as maintenance of the tank are not properly done due to not properly following the
rules and regulations of the construction work. In order to produce better working of the

equipment’s I had proceeded to test out the components. The testing process helped in finding a
lot of fault in the equipment’s.
1.3.4.2 Solutions
Strict rules as well as regulations related to the construction work should be followed so
that the design, installation and other processes should be done properly. Size of the value and
calculation works should be done accurately to overcome with any types of design issues in the
future. The faults found in the equipment’s were studied and then solution to each of them were
developed. The solution helped in the reusability of the products in the completion of the project.
CE 1.3.5 Plan to produce creative and innovative work
Installation of valve into the storage tank is an innovative as well as creative work to
determine the pressure into the tank. Proper determination of size and amount of valve is also a
significant importance of the project plan. In order to reduce the amount of risk, I had studied the
equipment’s before using them in the project. This helped in the elimination of faulty
equipment’s.
CE 1.3.6 Collaborative work
With help of the team members, I had prepared the calibration report so that we can able
finish the project on time. After preparation of the report, I had sent it to the supervisor for their
feedback so that on time I had to make possible changes.
