Caley develops deepwater lowering system for Gorgon project
EAST KILBRIDE -- Handling systems specialist, Caley Ocean Systems has been awarded a contract by Subsea 7 to design, manufacture and supply a deepwater lowering system (DLS).
The DLS will initially be deployed by Subsea 7 on the Chevron-operated Gorgon project, located off the northwest coast of Western Australia, to lower subsea structures weighing up to 950Te in water depths in excess of 1,300m.
The DLS comprises two double drum traction and storage winches and fully redundant controls, all mounted on an integrated grillage structure for rapid mobilisation onto the pipelay and heavy lift vessel Sapura 3000. The system will connect to a deepwater lowering beam (DLB) and connector. Each set of winches has its own dedicated hydraulic power unit for optimum control.
The range of equipment to be handled by the DLS in the Gorgon and Jansz-Io fields will include subsea structures and foundations and heavy lift spools.
