FIELD: transport.
SUBSTANCE: invention relates to underwater hydrocarbons production, particularly, to detachable mooring anchor turntable system and method of attachment of mooring buoy to turntable. Vessel 14 comprises hull 3, shaft 2 extending for hull top 40 to bottom 41, turntable 1 arranged to turn in said shaft on turntable support 4, 5 and manifold bearing structure 31. Said manifold bearing structure accommodates one or more pipelines. Said structure can be turned on turntable by manifold support 32. Turntable 1 comprises chamber 42 to receive mooring buoy 11 with one or several risers 12. Said risers can displace vertically the actuators 33 nearby manifold support 32 for vertical displacement of manifold bearing structure 31 relative to turntable 1 between turning position whereat structure 31 may turn relative to turntable and locked position whereat structure 32 is locked.
EFFECT: fast and reliable attachment/detachment of mooring anchor turntable system in bad weather.
