The invention discloses an anchoring method of a mother ship anchor-free machine, which belongs to the field of ocean engineering, and comprises the following steps: (S1) a pre-throwing position of ananchor is determined according to a preset position of engineering mother ship mooring; (2) the anchor chain groups are respectively connected with an engineering mother ship, and pre-anchored respectively; (S3) the floating crane ship hoists and lifts the middle section of the anchor chain set; (S4) the auxiliary tugboat is pushed in the direction away from the engineering mother ship, the anchor end of the anchor chain set is dragged through the towing anchor cable, and the anchor end is lifted to be away from the target anchor position; and (S5) the cable winding machine keeps the towing anchor cable stressed and tensioned, after the towing anchor cable reaches a preset position, the cable winding machine is completely loosened, the anchor chain set is thrown to the seabed, the liftinghook of the floating crane ship is loosened, and the anchor end of the anchor chain set is pulled back to the target anchor position under the action of the restoring force of the catenary. Accordingto the anchor dropping method of the mother ship anchor-free machine, the small-tonnage floating crane ship and the auxiliary tug are adopted to replace a high-horsepower tug for anchor dropping operation, the cost is saved, and the technical requirement of an anchoring system is met.
本发明公开了一种母船无锚机的抛锚方法,属于海洋工程领域,包括如下步骤:(S1)根据工程母船系泊的预设位置,确定锚的预抛位置;(S2)将锚链组分别与工程母船相连接,然后分别预抛锚;(S3)浮吊船对锚链组的中段进行起吊提升;(S4)辅助拖轮朝远离工程母船的方向推进,通过拖锚缆牵引锚链组的锚端,提升锚端并远离目标锚位;(S5)卷缆机保持拖锚缆受力张紧,到达预定位置后,卷缆机完全放松,使锚链组抛至海床上,松开浮吊船的吊钩,锚链组的锚端在悬链线回复力作用下拉回至目标锚位。本发明公开的母船无锚机的抛锚方法,采用小吨位的浮吊船加辅助拖轮替代大马力拖轮进行抛锚作业,既节省成本,又达到锚泊系统的技术要求。
