The present invention relates to a riser-umbilical cable direct connection type spherical turret mooring device wherein a thruster is applied. The present invention provides the riser-umbilical cable direct connection type spherical turret mooring device wherein the thruster is applied characterized by including: multiple risers vertically penetrating through a stem of a marine structure and directly connected to a riser porch on a shipboard; a spherical turret embedded in a turret housing; a riser spreader formed inside the spherical turret, fixated to the spherical turret housing, and through which the multiple riser penetrate; and the tunnel thruster installed in the lower side of a draft of the stem of the marine structure and controlling the marine structure to reciprocate within 180 degrees. According to the present invention, the riser-umbilical cable direct connection type spherical turret mooring device wherein the thruster is applied having a small and simple structure and system at low cost is obtained by having the spherical turret system rotating within 90 degrees in left and right sides which are an allowable deflection angle of the riser directly connected to the shipboard. Accordingly, expenses for the operation and maintenance are cheap, thus an effect of commonly using the riser-umbilical cable direct connection type spherical turret mooring device wherein the thruster is applied is obtained. |
