FIELD: transport.
SUBSTANCE: invention relates to device for detachment of moored floating offshore structures from buoy mooring when they are exposed to acts of nature. Device for mooring detachment for floating offshore structure and buoy mooring contains at least one high-pressure water jet propeller, supplemental low-profile contact surfaces on floating offshore structure and buoy mooring, detachable mechanical restraints. High-pressure water jet propeller is located on floating offshore structure and is facing buoy mooring to direct water between offshore structure and buoy mooring during detachment operation. Detachable mechanical restraints engages floating offshore structure and buoy mooring together during normal drilling and production operations.
EFFECT: quick detachment and quick increase of distance between mooring and floating offshore structure.
