Today I only attend meeting with Mr. Hafiz at MMHE meeting room.
QA/QC Issues:
1. Quality walkabout (monthly) is
on Wednesday 04/03/2015.
Reminder: To ensure
closure of temporary openings (penetrations/MCT) to protect the installed insulation
from excessive moisture.
2.
ABSB need to submit installation procedure and testing method for Plumbing
works Press fit copper & PVC - under final review. Still have comments and
ABSB to resubmit by 09/04/2015.
3.
ABSB to follow-up with Procurement to expedite the VO / Contract Amendment.
Especially for items with pending PO. (Lab Furniture, Bolt Tensioning
Equipment)
Engineering Issues:
1.
2 years spares list – ABSB propose by 05/03/2015. Submitted on 26/03/2015. TMJV
commented and ABSB need to resubmit by 09/04/2015.
2.
Enquiry on Safety equipment locker sent to ABSB on 03/04/2015. ABSB need to
submit proposal by 10/04/2015.
After lunch hour, I write hydro test report for Ball Valve.
Hydro pressure test procedure as the following.
Hydrostatic Seat Test Process
1.
Water for hydro – testing shall be clean, treated fresh water of objectionable
minerals, salt and inorganic materials.
2. Ensure all the vent points are
fully opened to atmosphere, prior to start water filling.
3.
Start filling water from the lowest point in the line using small diameter
branch connection and let the water overflow from the highest points.
4.
Stop the water at this stage and check all the flanges, valves and connected
accessories for any leakage while keeping the vents open. Hydrostatic test
maximum pressure shall be 20 Bar for the Ball Valve.
5.
After the water filling process is completed, pressuring will take place for
the start of hydro test. Open the first valve and close the second valve to
test the seat valve.
6. Start pumps the pressure from 0
bars to 8 bars.
7.
Next, when the pressure reaches 8 bars, hold it until 3 minutes for leak
inspection. Pressure maintain after 3 minutes holding, it’s proved that there
is no leakage at the seat valve.
Hydrostatic Shell Test Process
1.
After done the seat test and confirmed that no leakage at the seat valve, we
continue increase the pressure from 8 bars to 20 bars. Before pumps the
pressure to the valve, open the lock for the second valve to test the shell
valve.
2.
Start pumps from 8 bars to 20 bars and holding it until 3 minutes for the leak
inspection. If the pressure maintain after 3 minutes holding, it’s proved that
there is no leakage at the shell valve.
3.
When successful complete the test, de-pressurize and completely drain the
system and satisfaction from TMJV and Company representative.

Today I update weekly progress report and write Hydro pressure
test Report for Globe Valve.
Picture 1 shows weekly progress report.
Hydro pressure test Report for Globe Valve as the following.
Hydrostatic Shell Test Process
1.
Water for hydro – testing shall be clean, treated fresh water of objectionable
minerals, salt and inorganic materials.
2. Ensure all the vent
points are fully opened to atmosphere, prior to start water filling.

there is no leakage at the shell valve.
7.
After successful complete the test, de-pressurize and completely drain the
system and satisfaction from TMJV and Company representative.

Calculate the force for underlayment second test and write
summary hot water report for piping system. I calculate force for underlayment
second test using Newton Second Law. By using formula F=mA, I calculate the force
that can test piece received and make sure the test piece did not crack when
received the high force. Based on specification of PETRONAS give to us, the
minimum of force that underlayment can received is 25.5 N/mm2. So, I convert
from N to kg, I get 2.60kg/mm2. This shows that the underlayment will received
2.60kg/mm2 at the maximum point.
(9 April 2015 : Thursday)
Today I check the calculation of force for underlayment second
test. After lunch hour I write summary hot water report for piping system.
(10 April 2015: Friday)
Today I go to the workshop land C with Mr. Hafiz to see the work
progress at workshop land C.
Picture 2 shows they cut steel using 2 types of machine which is
Laser cutting machine and cutting machine.
Picture 3 shows workers do the welding process at workshop land
C.
Picture 4 shows lifting process using moveable crane. Operator
controls the movement of moveable crane using remote control.
