[0002] As we all know, ro-pax ferries are passenger ships, and therefore have stringent fire protection regulations. Centralized dust collection systems are a key component of the luxury of ro-pax and cruise ships, and they are large in scale. While air conditioning terminals are typically installed on the ship's ceilings, central dust collection systems require terminal connections to be installed in rooms, corridors, windows, and other locations. Fire protection requirements for these terminal connections are also a key focus of ship design and construction. Many compartments on ro-pax ships must meet B15 fire protection requirements (withstanding 15 minutes of flame impact and high temperatures in a fire test), so the connection between the terminal of the ro-pax dust collection system and the bulkhead must also meet B15 fire protection requirements.
