The invention belongs to the technical field of offshore wind power foundations, and discloses an offshore wind power multi-cylinder jacket foundation construction method and a workboat. The workboat is provided with a middle groove along the central axis of the workboat; the middle groove extends to the stern from the position, close to the bow, of the middle of a boat body and is communicated with seawater; a plurality of multi-cylinder jacket foundations are assembled in the middle groove and are connected with the workboat through connecting pieces with adjustable lengths; and the multi-cylinder jacket foundations are transported as an integral structure and can be directly installed and recycled by the workboat. The space of the workboat for placing the multi-barrel jacket foundations is saved, the gravity center height of the workboat can be adjusted through the air storage amount of the multi-barrel jacket foundations, and the applicability and stability in the transportation process are improved; the problems of infirm connection and structure friction damage caused by steel wire rope binding in a traditional pure dragging process are also avoided; and the offshore operation efficiency can be improved through installation or recovery, the offshore operation cost is reduced, and relatively good economic benefits are achieved.

    本发明属于海上风电基础技术领域,公开了一种海上风电多筒导管架基础施工方法及施工船,施工船沿其中轴线设置有中间槽,中间槽由船体中部靠近船首位置延伸至船尾,并且与海水相连通;将多个多筒导管架基础装配在中间槽中,与施工船通过能够调节长度的连接件连接,作为整体结构进行运输,并能够直接由施工船进行安装和回收。本发明节省了施工船放置多筒导管架基础的空间,可以通过多筒导管架基础存气量调节施工船的重心高度,增加运输过程中的适用性及稳定性;也避免了传统干拖过程中由于钢丝绳绑扎导致的连接不牢固和结构摩擦损伤的问题;安装或回收能够提高了海上作业效率,降低了海上作业成本,具有较好的经济效益。
