Finally after being towed for almost 2 days our work barge finally reach the location. The location is somewhere in the middle of Persian Gulf, specifically within Qatar water.
First thing that we need to do is setting the barge into the working position. The barge deck will be very busy with rigger working around to hook the dead man anchor to the crane, transfer it to the towing boat deck . Next to prepare is the marking buoy and the protection buoy. The riggers have to board the towing boat to install the protection buoy.
The different between the two buoys, marking buoy is the one that serve as the reference point where the anchor being landed on the seabed. The protection buoy on the other hand is installed as to ensure the anchor wire cable wouldn't touch sub sea structure such as pipe line. This is to avoid any damage to the pipe line.
HSE must ensure the guys working near the water, wear work vest all the time. Pneumatic tools for tightening the bolt shall be latched or secured firmly to the barge or rigid structure. Handling the job also must be based on buddy system due to the tools is heavy and also involve vibration with the limited working space. HSE as always, must ensure PTW in place and monitor closely POB (Personnel On Board) movement. As being discussed earlier in Part 1, H2S Escape set also must be available for the crew and provided to them in case they are assigned to work on the towing boat.
Finally when the barge is on position, then the work shall commence. Meanwhile the Marine Team lead by the Captain/Master will continuously monitor the weather and sea condition to ensure barge remain in the position.
Our team will wait for the Pipe Riser and the Riser Clamp delivered by supply boat or material/dumb barge. Sometime we at field had to do some modification to those clamps or risers due to on field measurement sometime is not tally as per in the drawing. How we could know this? Yes, the diver on board will dive and check the measurement, clamp angle and riser length prior fixing them on the jacket/sub sea part of the platform.
The clamp/riser installation will occupied all available crew on deck, the rigger, crane operator and the diver control room. Good communication is very essential to ensure safety and quality of the job.
HSE need to monitor all the operation process, review the JHA, ensure PTW in place and interrupt immediately if any unsafe act/condition spotted. Yes, everybody has the authority to stop job and definitely HSE has the ultimate say on this. The issue will be highlighted to Barge Foreman who is the deck work leader and barge master if the issue is related to Marine. The barge superintendent and Company Site Representative also must be in loop on such matter.
After all the objective is to ensure everyone back to their family safely after the safe job execution.
