The mooring arrangement of the inland ships often has the special considerations due to their operation environment conditions. The design of the mooring arrangement of the inland ship should be carried out and completed according to the requirements of the rules, matching limitations and design methods. The methods and key points for the design of the mooring arrangement of the inland ship are finally discussed based on the mooring arrangement of the Three Gorges ship-lift ro-ro ship.

Hoistable deck, as a particular equipment for Ro-Ro ships, is suitable for Ro-Ro ships that need to switch loading conditions between cars and trucks. The ships equipped with the hoistable decks can easily switch the situation of the loading deck according to the loading requirement to improve the efficiency of transportation.However, the fixed connection between the traditional pressure mist pipeline and the fire main pipe that is set at the bottom of the hoistable deck will obstruct the lifting of the deck. Some pipelines need to be removed and reconnected after the adjustment of the deck position, which is extremely disadvantageous in terms of safety and convenience. The tightness of the pipeline cannot be guaranteed after each disassembly and assembly, as well as a large number of pipelines demands to be disassembled and assembled whenever the hoistable deck is altered. A side pressure water mist spray system is proposed to solve the fire protection problem of the pressure water mist system on the hoistable decks.
