Flare Tip Replacement - West Kingfish, Australia

Project approach

Conbit explained the handling method used for many flare tip replacements worldwide. It is a more favorable method due to its cost-effectiveness and flexibility. 

After reviewing the available information, Conbit was confident of using a mechanical handling method to replace the flare tip. The flare tip access platform had sufficient strong points to carry loads of the lifting system and the flare tip. However, they had a client visit to guarantee and convince all stakeholders. Then, Conbit initiated the structural engineering phase.

The power of preparation

Conbit prepared for the maneuver with a thorough structural engineering plan. They ensured all operators were well-trained and had expertise in flare-tip operations. Conbit monitored the sea state and the wind speed. The flare tip access platform had sufficient strong points to carry loads of the lifting system and the flare tip. 

To assure all stakeholders involved, the factory acceptance test (FAT) took place during the structural engineering phase at the Conbit warehouse, with the client’s presence. Conbit utilized the base frame and lift boom to perform the mechanical handling in removing a pre-existing flare tip and replacing a new one weighing 442kg and measuring 3.747mm x 819mm. They used a supply vessel to move the existing and new flare tip to and from the platform. 

Conbit completed the entire project within four days. 

Challenges

Conbit was required to mobilize the lifting equipment concisely, testing the logistics team’s ability. With expert planning and shipping of lifting equipment, they successfully negotiated this challenge. Conbit monitored the weather prior to and during operations. They were anticipating terrible weather that could limit access to the platform and disrupt the overall operation. Conbit had to adjust the staffing schedule to ensure that the team would complete the work before the weather worsened. They dismantled the lifting equipment after the bad weather had passed, three days later.
