THRUSTER ASSISTED DIRECT RISERUMBILICAL CABLE DIRECT CONNECTION TYPE SPHERICAL TURRET MOORING SYSTEM

摘要

[0001] The present invention relates to a spherical turret mooring device for a riser / hum cable direct connection employing a thruster, comprising: a plurality of risers vertically penetrating a fore and aft of a marine structure and directly connected to a line riser port; A spherical turret housing fixed to a fore and aft end of the resilient structure; A spherical turret built into the turret housing; A riser spreader provided in the spherical turret and fixed to the spherical turret housing, the plurality of risers passing through; And a tunnel thruster installed below the stern portion draft of the marine structure to control the marine structure to reciprocate only within 180 degrees. [5] The thruster-applied riser / Provide a mooring device. According to the present invention, there is provided a spherical turret system that rotates only 90 degrees to the left and right of the allowable torsion angle of the riser directly connected to the line, thereby providing a riser / hum cable direct connection type spherical turret mooring device And the operation and maintenance cost is also low, so that it is possible to obtain an effect that it can be generalized.
