FIELD: drilling jobs; designing of buoys for loading/unloading fluid media, mainly oil. SUBSTANCE: buoy includes outer buoyancy member mounted for introducing it in intake cavity of ship and securing it in this cavity and central member mounted for rotation in outer member and designed for coming to anchor on sea bottom; it is adapted to passage of medium between transfer pipe which is connected during operation with lower end of central member and piping system on board the ship. Central member has housing projecting downward; housing has peripheral part adjoining adjacent end of outer buoyancy member and corresponding to shape of outer periphery; besides that, housing has lower part narrowing downward from outer peripheral part. EFFECT: enhanced reliability. 11 cl, 6 dwg
