The fire protection problem in the area above the open deck is becoming increasingly prominent as container ships become large-scale. The equipment and system layout of a 19 000TEU container ship are analyzed to provide a refitting scheme for the top-side firefighting. The feasibility of the scheme is then verified through three-dimensional modeling and fluid simulation calculation. It is proved to improve the fire control capability of the ship.

Fuel oil system is one of the most important systems to maintain the operation of ships. It is responsible for the functions of fuel purification and fuel transfer, which plays a vital role in the safety and stability of ship operation. As the main power source of the medium transmission in the fuel oil system, the operation condition of the fuel transfer pump will also directly affect the overall operation of the ship. It carries out the fault analysis and treatment for the abnormal event of the fuel transfer pump on the ship combined with the on-site fault characteristics, AFT Fathom calculation results and disassembly inspection. It can provide reference for the troubleshooting of the marine fuel transfer pump.
