Meanwhile, the single pile 3 can be directly turned over after being lifted, and the operation efficiency is improved. A tool storage area 116 and a facility storage area 117 are respectively arranged on two sides of the crane 2, the tool storage area 116 is used for storing tools such as a hydraulic hammer, a vibration hammer and a sling, and the facility storage area 117 is used for storing facilities such as an inner/outer platform, a ship, a ladder and the like. In this way, the area of the deck 11 can be fully utilized.

As shown in fig. 3, when the marine work material is the steel pile 4, the steel pile 4 is placed along the center line direction of the hull 1, and the center of gravity of the steel pile 4 is located in the light load work area 113 or the heavy load work area 112. A tool storage area 116 and a facility storage area 117 are respectively arranged on two sides of the crane 2, the tool storage area 116 is used for storing tools such as a hydraulic hammer, a vibration hammer and a sling, and the facility storage area 117 is used for storing a pile sinking positioning frame. So set up for can directly put on deck 11 and do not receive 2 davit rest condition's of loop wheel machine influence with 4 cooperation operations's of piling bar pile locating rack, can improve the daily maintenance efficiency of pile sinking location equipment simultaneously. And by adopting the placing mode, 12-18 steel piles 4 can be piled on the deck 11, thereby improving the offshore operation efficiency.

As shown in fig. 4 and 5, when the offshore operation material is the jacket 5, the jacket 5 stopped on the transport ship in the extrastring operation area 115 can be directly rotated 180 ° to be refuted to the crane ship stacking area by using the 360 ° full-swing performance, and the jacket 5 is uniformly placed on the deck 11 along the center line direction of the hull 1. Meanwhile, the jacket 5 can be directly installed, and the operation is simple and efficient. Meanwhile, the jacket can be used as a three-in-one ship for transporting, stockpiling and installing the jacket 5, and the applicability of the crane ship is improved.

Of course, the present embodiment is only to illustrate the type of the offshore operation material, and is not limited thereto, and a person skilled in the art may divide the operation area of the deck 11 differently according to different offshore operation materials according to actual situations, so as to ensure the stability of the crane ship during operation. Thus, the arrangement of the deck 11 is more flexible, and the requirements of offshore operation in various basic forms can be met.

Optionally, in some embodiments of the present invention, the size of the crane base 21 is 16M-20M, and the radius of the blind area 111 of the crane 2 is 15M-20M.

A coverable working area 114 is further defined on deck 11, and an extrachord working area 115 is further defined in the offshore area outside the crane ship. The skilled person can divide the working area that can cover the working area 114 and the extrachord working area 115 according to actual conditions, and can ensure the normal operation of the crane 2 and the stability of the crane ship.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments.
