Conbit partnered with CR3 to deliver the full scope of engineering, project preparation, and offshore execution for flare tip replacements on the Arthit platform, operated by PTTEP. In addition to replacing the flare tips, Conbit supported various maintenance activities on the flare tip platform, ensuring a seamless and well-coordinated operation from start to finish.
The project posed a unique logistical and engineering challenge: replacing three individual flare tips located at different positions across the deck. Two of these flare tips consisted of two separate components—a flare tip and a transition piece—adding further complexity to the handling and installation process.
To execute the replacements and associated maintenance tasks, the team completed ten individual lifts. Given the wide distribution of the flare tip locations, Conbit designed a custom gantry system with a 9.6-meter span. This wide reach allowed efficient access to each flare tip location without the need for repositioning.
Additional complexity came from the increased height of the flare tips due to their two-section design. To manage this, the gantry system was engineered to provide a vertical reach of 9.7 meters. Lifting operations were carried out using a combination of a main winch and a service winch, with the gantry system constructed using Conbit’s LRE1 and two LRE2 modules.
Thanks to the longstanding collaboration between Conbit and CR3, the project was executed smoothly, even in the face of a minor weather delay. The team successfully completed the work on schedule, demonstrating the strength of strategic engineering and offshore coordination.
