PTT Public Company Limited planned to do maintenance works on their flare system on the Gas Separation Plant in Map Ta Phut, located in Thailand. CR Asia was the main contractor for this project. They requested Conbit’s expertise to assist with lowering the riser pipes of GSP5 & GSP6 so that these would be accessible for maintenance.
Besides supervision, Conbit was also responsible for the procurement of lifting equipment.
One flare stack can be lowered in a retractable flare while the others remain in operation. This enables maintenance activities to be performed at ground level without drastically decreasing the flare capacity.
Because of the weight and size of the retractable flare risers, an experienced crew is required to perform this lifting service. Also, local circumstances and the flare condition can require adjustments throughout the project. Conbit has experienced many unforeseen circumstances in their projects and therefore can adapt to changing situations.
The project was executed safely and on time. It was a great team effort with CR Asia.
