The invention provides a load adjusting method for a hoisting working condition of a wind power installation vessel. The load adjusting method comprises the following steps: calculating a load adjusting value; first total pressure on each pile leg is obtained through calculation; according to the difference value between the first total pressures on the four pile legs, a load adjustment value Wt is obtained through calculation; the load adjustment value Wt meets the following conditions: after the first pile leg group actively bears the load adjustment value and the weight borne by the second pile leg group is reduced by the load adjustment value, the second total pressure after the pile legs corresponding to the pile-winding crane are adjusted is close to the second total pressure of the other three pile legs, and the two pile legs distributed diagonally form one pile leg group; the pile winding crane is arranged on one pile leg of the second pile leg group; load adjustment operation; pre-ballasting operation is conducted through diagonal pre-ballasting, and after the pre-ballasting operation is completed, the ship body is lifted to the preset operation height; and the second pile leg group is kept still, so that the first pile leg group actively bears the load adjustment value Wt, and the weight borne by the second pile leg group is reduced by the load adjustment value Wt.

    本发明提供了一种风电安装船的吊装工况的载荷调整方法,包括以下步骤:载荷调整值的计算;计算得到各桩腿上的第一总压力;依据四个桩腿上的第一总压力之间的差值,计算得到载荷调整值Wt;载荷调整值Wt满足下述条件:第一桩腿组主动承担载荷调整值,第二桩腿组所承担的重量减少载荷调整值后,绕桩吊对应的桩腿调整后的第二总压力与其余三个桩腿的第二总压力接近,呈对角分布的两桩腿构成一桩腿组,绕桩吊设置于第二桩腿组的其中一桩腿上;载荷调整操作;通过对角预压进行预压载操作,完成预压载操作后,提升船体至预定作业高度;保持第二桩腿组不动,使第一桩腿组再主动承担载荷调整值Wt,第二桩腿组所承担的重量减少载荷调整值Wt。
