MOORING SYSTEM WITH SEPARATED ANCHOR LINES AND/OR MARINE RISER SYSTEM Russian patent published in 2014 - IPC B63B21/50 B63B22/02 

FIELD: transport.

SUBSTANCE: invention relates to shipbuilding and concerns vessels for hydrocarbon production. Vessel contains hull with tower, cavity in the tower and mooring buoy removably fixed in the cavity. Note that the buoy contains floating body and is load-carrying element for a number of marine risers extending to underwater well for hydrocarbon production and for a number of anchor lines connected with sea bed. When the buoy is attached to the cavity the buoy is fixed to lifting element connected with hoist on vessel to lift the buoy. Each anchor line and/or marine riser is connected by its top end with locking member, and the locking member is attached to pulling member. During lifting, each anchor line and/or marine riser is movable relative to floating body along the length of anchor lines and/or marine risers. After floating body has been connected with cavity the locking member engages with contact member on floating body thus supporting anchor line and/or marine riser hanging from floating body. Pulling member can be attached to mooring buoy by means of resilient device working in compression.

EFFECT: better operational performance of mooring system.
