The offshore wind power operation and maintenance mother ship comprises ballast tanks located below a bottom plate in the ship, the ballast tanks comprise a seawater ballast tank and a heavy ballast tank, the heavy ballast tank is distributed at the position away from the central axis of the ship, and the seawater ballast tank is distributed at the position close to the central axis of the ship. It can be seen that the method has the beneficial effects that the gravity center height of the ship with the fixed ballast added is lower than that of the ship without the fixed ballast added, the transverse free liquid level inertia moment of the ship is reduced, the initial stability of the ship is improved, and then the integrity stability and the cabin breaking stability of the ship are improved; and the fixed ballast tank reduces the water inflow of regional damage, so that the subdivision index of ship cabin damage stability is improved, and the safety of ship cabin damage is improved. In addition, the inertia radius of the ship in the length direction of the ship is increased, the rolling period of the ship is increased, the rolling period of the ship is farther away from the wave period of the target sea area, the shaking degree of the ship is reduced, and the seakeeping performance of the ship is improved.
本发明公开一种海上风电运维母船,包括位于船舶内底板下方的压载舱,压载舱包括海水压载舱和重压载舱,所述重压载舱分布在远离船舶中轴线的位置,海水压载舱分布在靠近船舶中轴线的位置。可以看出本发明的有益效果在于:增加固定压载的船舶重心高度低于未增加固定压载的船舶重心高度,且减少了船舶的横向自由液面惯性矩,提高了船舶初稳性高,进而提高船舶的完整稳性与破舱稳性,且固定压载舱降低了区域破损的进水量,从而提高了船舶破舱稳性的分舱指数,增大了船舶破舱的安全性。此外,增大船舶的绕船长方向的惯性半径,使船舶的横摇周期增大,使船舶的横摇周期更加远离目的海域的波浪周期,减少船舶的摇晃程度,提高了船舶的耐波性。
