All LNG bunkering stations are required to be fitted with a fixed dry chemical powder system. The Dry Chemical Powder system delivered by RAFT holds a DNV_GL type approval according to IMO Res.391(95).
Inside the bunkering station, eight spiral nozzles are installed to cover all possible leak points. To avoid clogging and to ensure an even distribution of powder, the nozzles are symmetrically distributed. Upon system release, the powder tank is pressurized with nitrogen.
The system is suitable for B and C class fires. The dry chemical powder extinguishes the fire by suffocation and chemical intervention in the combustion process.
