InterMoor to Design, Fabricate, Install Delta House FPS

InterMoor won a contract for design, fabrication and installation of 12 suction pile anchors, pre-set installation of 12 chain / polyester / chain mooring lines and hook-up of the LLOG Delta House production semi-submersible. The work will be conducted in the Mississippi Canyon 254 block of the U.S. Gulf of Mexico.

The project will involve suction pile design, fabrication and installation, followed by pre-set mooring installation and pre-set mooring hook-up of the FPS. The 12 piles will be 85 feet long and 16 feet in diameter weighing approximately 150 metric tonnes each. They are designed to be used as permanent anchors for the project. Installation activities are planned for mid-2014.

Delta House will be moored in 4,500 feet of water and is LLOG’s second Exmar-designed Opti deep-draft, semi-submersible production system in the region. 

Tom Fulton, InterMoor’s president, states, “Our approach to the award process involved paying close attention to the client’s needs – which included comprehensive engineering, design, fabrication and installation procedures and plans – and preparing a detailed proposal that broke out each phase of the work scope. This project will add to InterMoor’s already strong track record for permanent moorings which includes some of the largest deepwater mooring projects around the world, including Kikeh, Shell Auger, ATP Mirage and the Williams Gulfstar FPS.”
