FIELD: devices for single-point mooring of ships and loading and unloading fluid medium. SUBSTANCE: for single-point mooring of ships, use is made of fixed structure secured on sea bottom, ship's mooring chain and flexible pipe line for transportation of fluid medium to or from moored ship. Compensation for translational motion of ship and her turns is effected due to turn of interconnected members. Axes of rotation of these members intersect at point lying on axis of symmetry of one of members which is supported by fixed structure second on sea bottom. Ship's mooring chain and flexible pipe line for transportation of liquid medium to or from are rotatably connected to other member. System used for realization of this method includes toroidal device, fork and swivel bush. EFFECT: reduction of action of loads on moored ship, flexible pipe line and mooring chain. 5 cl, 4 dwg
