[0003] There is a warehouse on the deck of the ship. For a ship whose side wall of the warehouse is the outer plate of the ship, in order to allow the staff to pass between the warehouse and the supply ship conveniently, the door of the warehouse can be set at the same time as In this case, it is impossible to design a permanent fixed stairway outside the cargo warehouse door to connect the cargo warehouse and the supply ship, and a detachable stairway is used. On the one hand, the stairway does not use It will take up a large warehouse space. On the other hand, the stairway needs to be installed and disassembled every time it is used, which is time-consuming and laborious.
