Flare Tip Replacement - Anoa AGX

Shutdown maintenance work

During the Anoa Gas Exploration (AGX) platform shutdown, the flare tip needed to be replaced.

The Anoa Gas Exploration (AGX) platform, operated by Premier Oil, is located about 1,100 km north of Jakarta, Indonesia.

Premier Oil assigned Kotaminyak with the task of replacing the existing flare tip. It includes the production, delivery, and installation of the new flare tip.

Kotaminyak contracted Conbit for the replacement services, including the required engineering. They also asked Conbit to replace the actual flare tip with a new one supplied by Kotaminyak.

Watch how we prepare and execute

Temporary lifting solution used by Conbit to do the flare tip replacement

Lifting equipment

The pieces of equipment used for this heavy lifting challenge were an aluminum lifting boom, a gantry, rigging equipment, and a lifting winch located on the cellar deck. The winch was used to lift the old and new flare tip to and from the supply vessel.

In this project, the rope-access crew went up to the flare stack, lifting the light rigging equipment. Once this light rigging was at the flare stack, they lifted the modular lifting equipment to the flare stack.

Preparation

Before the engineering starts working on the final lifting plan, a project manager travels to the asset to perform a site visit. The primary goal of flare tip replacement is to ensure a safe operation and minimize shutdown time. Conbit’s flare-tip handling services are well prepared and adapted specifically to each project.

The mechanical handling systems are tested and certified before the shutdown. In this case, the team tested the system first at Conbit’s warehouse. Then, they conducted the load test in Indonesia.

This approach ensured that the time lost during the exchange process and the overall shutdown time were kept to an absolute minimum.

Team effort

This project is an excellent blueprint of Conbit’s strengths in designing smart lifting solutions, deploying an experienced execution team, and effectively managing all the necessary activities. Above all, this project was successful due to the great teamwork between the various parties involved, with Kotaminyak as the main contractor and Premier Oil as the end customer.
