Mooring disconnect arrangement

摘要

A mooring disconnect arrangement (10) for a floating offshore structure (16) and a mooring buoy (18). At least one high pressure water jet (12) is positioned to direct water between the floating offshore structure and the mooring buoy. The floating offshore structure and mooring buoy are also provided with specially shaped complementary surfaces (22, 24) to assist in disconnection and separation. One or more mechanical restraining devices (20) may be used to retain the floating offshore structure and mooring buoy connected together during normal drilling or production operations.
