CNG Powered Reverse Stern Drive Tug
On Friday, Damen Shipyards of the Netherlands, German engine manufacturer MTU Friedrichshafen (a subsidiary of Rolls-Royce Power Systems) and Denmark’s SVITZER have partnered to produce a CNG powered reverse stern drive (RSD) tug by 2016. The new RSD CNG tug combines high power with lower fuel costs and a substantial reduction in emissions. The new 16-cylinder pure gas engine being developed by MTU is based on its workboat Series 4000 M63 diesel engine. The 2,000 kW engine will feature a multipoint gas injection system and will meet IMO Tier 3 emission legislation without the need of additional exhaust gas after treatment.
