First LNG-Powered Tugboat Sets Sails

M/T Borgøy, the world’s first tug to be fuelled by the much more environmentally friendly liquefied natural gas (LNG), designed by Norwegian Buksèr og Berging in-house team with the assistance of Marine Design AS in Norway, further developed by Sanmar’s modern shipyard in Istanbul, completed her sea trials successfully this month and started her maiden voyage to Norway on January 14.

The engines, propulsion package and LNG system were delivered by Rolls Royce. Usage of LNG in this tugboat eliminates sulphur emissions, bring particulate matter emissions down close to zero and reduce the discharge of CO2 and NOx by 26 percent and 80-90 percent respectively. She will be operated by Buksèr og Berging in Statoil (STO)’s Kaarstoe Gas Terminal.
