The invention discloses an underwater gravity anchor relay type lowering method and lowering system. The lowering method comprises the steps that S10, a barge loaded with a gravity anchor is driven to a first temporary working area to be temporarily anchored and fixed; s20, the floating crane is driven to the side of the barge to be temporarily anchored and fixed; s30, the floating crane is used for lowering the gravity anchor to the seabed surface; s40, connecting an (i + 1) th steel wire rope to the ith steel wire rope; the initial value of i is 1; s50, the lifting hook is lifted to enable the gravity anchor to be separated from the seabed surface; s60, whether the total length of all the steel wire ropes is larger than the water depth of the target working area or not is judged; if yes, the floating crane is driven to the target working area for lowering the gravity anchor; if not, driving the floating crane carrying the gravity anchor to the (i + 1) th temporary working area, and lowering the gravity anchor to the seabed surface; and i is made to be equal to j + 1, the step S40 to the step S60 are repeated, and j is the number of times of the step S60. The lowering method can solve the problem that the steel wire rope goes deep into the water surface and cannot be removed in the lowering process of the underwater gravity anchor.

    本申请公开一种水下重力锚接力式下放方法及下放系统,下放方法包括:步骤S10:将装载有重力锚的驳船行驶至第1个临时工作区域进行临时抛锚固定;步骤S20:将浮吊行驶至驳船旁进行临时抛锚固定;步骤S30:使用浮吊下放重力锚至海床面;步骤S40:在第i根钢丝绳上接第(i+1)根钢丝绳;i初始值为1;步骤S50:提升吊钩使重力锚脱离海床面;步骤S60:判断所有钢丝绳的总长度是否大于目标工作区域的水深;若是,将浮吊行驶至目标工作区域进行重力锚的下放;若否,将携带重力锚的浮吊行驶至第(i+1)个临时工作区域,并下放重力锚至海床面;使i=j+1,重复步骤S40至步骤S60,j为进行步骤S60的次数。该下放方法能解决水下重力锚下放过程中钢丝绳深入水面无法解除的问题。
