Week 8 - 24th-29th May 2010

After 2 months in MMHE, experiences and technical skills here are difficult to obtain elsewhere. This week started off with a little bit slower but managed to pick up towards the end. I was focusing myself on drawing and single line diagram. Mainly on 6.6kV switchgear panel. Module 7 will soon go through weighing and therefore cables below it needed to be clear. Progress on helideck was good. Almost everything was prepared to be tested. A big change since I last visited. Found 2 more types of lighting, indication and flood light. Fourth day of the week, I participated in testing of Potable Water Pump and Wash Water Pump. Uncoupled test run or solo-run test was carried out to see motor's original performance. Temp., rotation, vibration, rpm, starting & running amp, winding resistance & isolation and Megger test were performed on each motor. SSP-5510 and SSP-5530 went through a Current Injection Test (CIT). It checked the tripping time of the circuit breaker with it's percentage load. Usually 75%, 100%, 200% and 300% more than it's normal maximum value are injected using Current Injector.

Week 7 - 17th-22nd May 2010

Toolbox meeting for T&C and PMT will be separated from this week onwards. I get to learn types of starters in module 6 and how to differentiate it. Mr. Kamal took the effort to explained more detail about DOL starter by referring to single line diagram. There were "Torque Check" through out this whole week. I involved myself in placing GENSET to know the preparations and procedures. Voltage Stabilizer had some voltage drop in the output. Tried to find the fault with technicians. From there I again exposed to new items, True Clamp Meter where current inside a cable can be measure easily. Supervisor finally allowed me to perform Ducter Test. Meanwhile I learned how to use Torque Check equipment from other technicians. Followed Mr. Shahrizal to find fault for RCU panel after receiving report from technicians. Went around with Mr. Suhaimi to check lighting status as preparations to offer testing to client.

Week 6 - 10th-15th May 2010

In week 6, I went through the "Electrical Checksheet Overview" for Petronas Carigali Sdn Bhd. We can find system number, system description, equipment description, construction inspection sheet (CS) and functional test sheet (FS). CS and FS are so important for Testing & Commissioning as a prove of work completion and also verified by client. Visited MSF as there is a problem with the air compressor. Water are dripping in the panel during rain. Had discussion to solve while waiting for vendors to come. I was introduced to Uninterrupted Power Supply (UPS) and explained of its function.

Week 5 - 3rd-8th May 2010

Fifth week was rather busy but it was a fruitful week. Finally I was able to get my feet step on the helideck. Parameter light can only be found on helideck and saw the process of glanding the cable. Visited "CCR Room" or Plant Monitoring & Control Room (PMCS). Able to see vendor doing changes on drawer position indication for starters and what's inside the soft starter panel of 5510 & 5530. Get an overview of LOTO system on DB-7862. Did a short report on "Vibrotip Data Collector" requested by Mr. Azhari. So lucky invited to attend confined space meeting at PMT office. From there we get to learn the requirement to work in confined space. Given task to do "Reticulation Report" by supervisor. I also witnessed "Megger Test" on MCC-7810, space heater for DB-7862. After a month, I get to performed a "Control Test" for MCC-7850 using Digital Multimeter under supervision of technician, Mr. Azami. Another Saturday yet another housekeeping day.

Week 4 - 26th-30th April 2010

Week 4 was getting more challenging. It started off with Mr. Shahrizal visiting MSF and switchgear room. Did researched on types of circuit breakers and it's usage. Visited MSF again to see the defect of air compressor and technicians are working on it. At the same time Mr. Azhari briefed me on the flow of air compressor and dryer. Being exposed to "RCCB Digital Tester" while offering testing to client. It's used to check continuity test as well as tripping time test. Learned little bit skill of glanding cable. Had opportunity to witnessed "Torque Check" on busbar followed by "Ducter Test" to check the resistance between joint to joint of busbar. Readings below 10 micro Ohm are consider good.
