The invention provides an offshore dragging system and method for a floating fan foundation. The floating fan foundation comprises three stand columns distributed in a regular triangle shape, heaving plates located at the bottoms of the stand columns and a herringbone deck used for being connected with the tops of the three stand columns. The offshore dragging system comprises a main tugboat, a main towing cable, an auxiliary tugboat and an auxiliary towing cable; the main towing cable is a Y-shaped cable and is used for connecting the main tugboat with one heaving plate in the floating fan foundation or connecting the main tugboat with two stand columns in the floating fan foundation; when the main towing cable is used for connecting the main tugboat with the two stand columns in the floating type draught fan foundation, the auxiliary towing cable connects the rest stand columns in the floating type draught fan foundation with the auxiliary tugboat; when the main towing cable is used for connecting the main tugboat and a heaving plate in the floating fan foundation, the auxiliary tugboat is in an idle state; according to the state of the floating type draught fan foundation, the connecting mode of the main tugboat and whether the auxiliary tugboat is arranged or not are flexibly selected, and therefore the wet dragging efficiency and the wet dragging safety of the floating type draught fan foundation are guaranteed.
本发明提供一种浮式风机基础的海上拖拽系统及海上拖拽方法,浮式风机基础包括呈正三角形分布的三个立柱、位于各个立柱底部的垂荡板及用于连接三个立柱顶部的人字形甲板;海上拖拽系统包括主拖船、主拖缆、副拖船和副拖缆;主拖缆为Y型缆,用于连接主拖船与浮式风机基础中的一个垂荡板或用于连接主拖船与浮式风机基础中的两个立柱;当主拖缆用于连接主拖船与浮式风机基础中的两个立柱时,副拖缆将浮式风机基础中的剩余立柱与副拖船连接在一起;当主拖缆用于连接主拖船与浮式风机基础中的垂荡板时,副拖船处于闲置状态;本申请根据浮式风机基础的状态,灵活选择主拖船的连接方式及是否配备副拖船,以保证浮式风机基础的湿拖效率和湿拖安全性。
