However, in the construction of high-end passenger and vehicle ferries, due to the large number of equipment in the engine room and pump room and the narrow layout space, the passenger and vehicle ferries have eliminated the seawater main pipe and replaced it with a pipe of DN600 or above to save space. The filters in the ship standard CBT497 are large and bulky, and are far from meeting the design requirements of special locations. In addition, the pump room problem is more prominent during the construction process, and the narrow passage makes it impossible to install the filter.
