The invention relates to the field of offshore wind power construction, in particular to an offshore wind power single pile foundation construction method and a special ship. According to the method, after accurate positioning is conducted through a piling positioning system, construction of a fixed guide platform is conducted firstly; and platform construction is completed, the special ship crane completes hoisting and overturning of the steel pile, the steel pile is fed into a guide platform hoop, after the perpendicularity is adjusted, the steel pile begins to enter the mud by self weight, and self-weight entering into the mud is completed. The special ship crane lifts a hydraulic hammer to the top of the pile, hammering pile sinking is started, and the perpendicularity is measured and guaranteed in the process until pile sinking is finished; and the special ship demolishing the guide platform, hoisting an accessory structure, and moving the ship to the next machine position after construction is completed.
本发明涉及海上风电施工领域,特别涉及到一种海上风电单桩基础施工方法及专用船。该方法根据打桩定位系统精确定位后,先进行固定导向平台的施工;平台施工完成,专用船吊完成起吊、翻转钢桩,并将钢桩喂入导向平台抱箍,调整好垂直度后,钢桩开始自重入泥,自重入泥完成。专用船吊机起吊液压锤至桩顶,开始锤击沉桩,过程中测量保证垂直度,直至沉桩结束;沉桩到位,专用船拆除导向平台,吊装附属结构,施工完成移船前往下一个机位。
