Hyjack platform with compensated dynamic response |
摘要 |
An offshore platform structure is disclosed for temporarily using a jack-up rig for well operations in deepwater applications in which a jacket base supports a surface tower and a subsea rig support interface adapted to accept the jack-up rig for well operations. The bottom founded jacket base is designed for dynamic response with the mass of the jack-up engaged and at least one ballastable rig support buoyancy tank connected to the rig support interface whereby the weight of the jack-up rig is substantially offset by buoyant forces supplied by the rig support buoyancy tank when the jack-up rig is deployed on the jacket base and the mass of the jack-up rig is substantially replaced in the offshore platform structure by ballast in the rig support buoyancy tank when the jack-up rig is removed.
