FIELD: transport.SUBSTANCE: mooring device for vessel (1) comprises drilling well (2), turret (3) arranged in drilling well to run in top main bearing (4) and bottom extra bearing (5), and mooring lines (6) secured to lower part of said turret. Turret lower area comprises several box-like torsion elements (7) spaced apart in circle, each extending, in fact, vertically between top end secured to said turret and bottom free end. Bending resistance of torsion elements in circular direction is greater than that in radial direction. Mooring lines are secured to torsion elements nearby bottom free ends while bottom extra bearing is composed by bearing elements (8) directed outward and secured to torsion elements and bearing rings (9) directed inward and secured to drilling well. At horizontal load acting on torsion element from appropriate mooring line, its bearing element does not contact with bearing ring.EFFECT: simplified design, better working properties.10 cl, 2 dwg |
