Subsea Pipeline and Treanching

Today's lesson is about subsea pipeline and also treanching. It was explained by one of the Marine Executive, En. Fazli and also based on the assignment by trainee supervisor, En. Fahidin Ismail.

The day started off with the trainee participation in the Weekly Operation Meeting (WOM) chaired by the Trainee Supervisor, En. Fahidin himself. All the issues in regarding the operation of the company was discussed in the WOM divided by the department in the company which was Safety Department, Marine Department, Engineering Department and also the Administration Department. At the end of the meeting, En Fahidin arranged a meeting with the trainee and also the apprentice for a short briefing. En Fahidin told us that he was the first one to apply the writing of Minutes of Meeting concurrently with the progress of the meeting. He said that with this method, the time taken to prepare the Minutes of Meeting (MoM) can be reduced and the MoM may be distributed among the employees for their attention and also their immediate action. He expected us to be able to write the MoM in the coming meeting.

Later, I was assigned by En Fahidin to research through the Internet for supplier for the concrete collar used to weigh down the subsea pipeline. It was known that the concrete collar strap was required by Petronas for their project. I managed to find some suppliers who were able to supply collar strap that may work for subsea operation. The strap is required to fixed the concrete to the pipeline for area that have a strong water current. This is to ensure that the pipeline always be under the seabed for safety purpose.

Later in the day we were introduced by the process of treanching. Treanching was made using the treancher which will be placed and moved along the pipeline. The treancher consist of a pump that will shoot high velocity of water that will be able to penetrate the seabed to acquire the desired depth for the pipeline installation under the seabed. Treancher will be controlled by a computer and will be monitored by a skilled operator located on the work utility barge. The treanching process will end once the whole length of the pipeline has been submerged under the seabed and after the diver has checked the safety of the pipeline under the water.

I was also being educated with the project terms that might be useful in my future career. The terms and acronyms that I have learned for the day was

1) TCOT - Terengganu Crude Oil Terminal
2) MCOT - Miri Crude Oil Terminal
3) BCOT - Bintulu Crude Oil Terminal
4) LCOT - Labuan Crude Oil Terminal
5) SOGT - Sabah Oil Gas Terminal

It has been a great day in Ombak Marine Group. I have learned more every day while doing my industrial training in Ombak Marine Group other than obtaining the working experience and exposure. Hope to learn more about the Oil and Gas industry in the day after.
