Thruster system of wind power installation vessel

The utility model relates to a thruster system of a wind power installation vessel, especially relates to a thruster of a wind power installation vessel capable of satisfying the DP2 level dynamic positioning standard. The thruster system of the wind power installation vessel belongs to the thruster field of controlling the steering torque of the heading. The thruster system is characterized in that the thruster system is constituted by a main thruster group and a bow part lateral thruster group; the main thruster group is vertical to a central line of the ship, and is disposed on a bottom part of a stern, and the bow part lateral thruster group is disposed on the bow part along the central line of the ship. The utility model is advantageous in that the thruster system of the wind power installation vessel can satisfy the requirements of the DP2 level standard of high redundancy, large thrust, and high cruising speed; the economical speed index of the ship cannot be influenced, when one of the thrusters breaks down; the working efficiency can be improved by 5%, and the cruising speed of ship can be improved by one knot to two knots, and therefore the conveying time of the wind power generator unit can be saved, the conveying costs can be reduced, the fast-positioning and the stable and reliable hoisting of the wind power generator unit can be realized.
