LNGPac Fuel Gas Supply System

Wärtsilä LNGPac ist das weltweit meistinstallierte LNG-Kraftstoffsystem mit geschätzt 40% Marktanteil. LNG als Schiffskraftstoff (anstelle von HFO/MGO) wird durch den IMO 2020 Schwefelgrenzwert und EU ETS vorangetrieben. Der IMO IGF Code (International Code of Safety for Ships using Gases or other Low-flashpoint Fuels) regelt die Sicherheitsanforderungen. LNGPac umfasst den kompletten Kraftstoffpfad vom LNG-Tank über Verdampfer und Gasregeleinheit bis zum Motor.
