A marine LNG filling station is a service facility established in inland river or coastal areas for filling LNG fuel ships. According to the filling type, it can be specifically divided into three categories:
① Filling LNG fuel ships berthed at the port from a truck.
② Filling LNG fuel ships berthed at the port from an LNG filling station established on a pontoon using low-temperature pipelines from a fixed onshore storage station.
③ A mobile filling station refers to a filling station established on a powered vessel, featuring mobile filling service.
The fixed marine LNG filling station has quick connections and uses high-flow dispensers to ensure fast filling; it adopts hose connections with import breakaway devices to ensure safe filling; and optimizes the control system to achieve automation of the filling operation process.
