InterMoor has completed design, fabrication and installation of two suction piles for the Thunder Hawk development in the Gulf of Mexico.
The two 16 ft. diameter-by-95 ft. long suction piles, each weighing 159 tons, were designed for 550 kip holdback capacity using a "Devil's Claw" chain ratcheting mechanism. They were fabricated and function tested at InterMoor’s Amelia, La., facility to meet API RP 2SK standards.
"A benefit of this project was advancing our A-frameless technology, which will be applicable for future suction piles and SEPLAs on vessels that do not have an A-frame," said Tom Bauer, project manager.
InterMoor also designed, tested and used a new PS-24 Vent Cap system instead of traditional butterfly valves, which reduced costs, shortened delivery time and ultimately proved to be highly successful.
