FIELD: water transport; technology of mooring tankers. SUBSTANCE: turret is mounted in front of vertical central axis of ship in well on support unit for relative rotation of turret in case of misalignment of longitudinal central axis of ship and direction of forces generated by surrounding medium. Ship is made fast to sea bottom by means of many mooring lines between turret and bottom. Each mooring line is made fast to turret. Many hoists are lowered from turret to sea bottom for receiving oil or gas from operating wells in sea bottom. Float buoy is rigidly secured to each mooring line in position when this mooring line is located between turret and sea bottom forming chain line by section of mooring line between turret and this buoy. Mooring line is constantly kept away from hoists by means of chain line of section of each mooring line. In securing the buoy to its mooring line, angle is formed at point of attachment of mooring line to turret between its vertical axis and line passing through this point and float buoy. This angle exceeds angle between line passing through this point which is parallel to sea surfaces and line passing through this point and buoy. Buoy possesses buoyancy sufficient for submergence of buoy to depth of from 35 to 150 m. According to another version, displacement of buoy is equal to at least 20 metric tons and buoy is submerged to depth of at least 35 m and deeper. Mooring system includes well for positioning the turret inside it. EFFECT: possibility of mooring the ship in high seas. 12 cl, 4 dwg
