[Problems to be solved by the invention]

 As described in the prior art, the suction main pipe and the suction branch pipe not only penetrate the bulkhead stool and the central stool, which are the strength members of the hull, but also perform welding and piping work in the limited space inside the stool. It caused problems such as reduced hull strength and cracks from welds, as well as process delays due to mixed operations. In addition, hydraulic actuators and hydraulic conduits were immersed in the cargo, and lacked safety aspects such as corrosion and difficulty in maintenance.

The present invention has been made in view of such inadequacy of the prior art, and has as its object to provide a suction main pipe and a hydraulic actuator in a longitudinally extending central stool. By installing a suction valve, the suction main pipe does not penetrate the partition wall tool, reducing the hull strength and eliminating the dangers such as cracks from the welded parts. The process will be clarified, work will not be mixed, and work efficiency will be improved. In addition, corrosion of hydraulic actuators and hydraulic conduits will be eliminated, maintenance will be easier, and safety will be improved.
