The invention discloses a crane ship. The crane ship comprises a ship body, a crane and two auxiliary ship bodies; the crane is arranged at one end of the ship body; the auxiliary ship bodies are arranged at one end of the ship body provided with the crane; and the two auxiliary ship bodies are symmetrically distributed on the two sides of the center line of the ship body, and a pile sinking positioning frame is suitable for being placed between the two auxiliary ship bodies. Through arrangement in this way, during offshore operation, the crane ship can completely meet storage of the pile sinking positioning frame, so that the pile sinking positioning frame does not need to be placed to special ships such as a self-elevating platform and a flat barge, and the operation cost is reduced; andtherefore, a single crane ship can be used for carrying out 10 m-level offshore wind turbine single pile sinking operation, so that operation is more efficient, and the cost and the safety risk are more controllable.
本发明公开了一种起重船,该起重船包括:船体;吊机,设置在所述船体的一端;若干辅助船体,设置在装有所述吊机的船体一端;两个辅助船体,设置在装有所述吊机的船体一端;两个所述辅助船体对称分布在所述船体的中心线两侧,两个所述辅助船体之间适于放置沉桩定位架。如此设置,在海上作业时,该起重船能够完全满足沉桩定位架的存放,从而不需要置于自升式平台、平板驳船等专用船舶,减少作业成本。进而可以单个起重船进行10m级海上风机单桩沉桩作业,使得作业更高效、成本和安全风险更可控。
