Terntank’s chemical tanker employed with Winterthur Gas & Diesel’s (WinGD) low-pressure X-DF gas admission technology has successfully finished its sea trials, marking the move of the first dual-fuel two-stroke engine employing X-DF from technical concept to commercial operation.
The 15,000 DWT tanker features a Wärtsilä RT-flex50DF engine that uses the X-DF technology installed as the main engine to drive a single propeller in Terntank’s Ternsund.
The sea trials, which were undertaken from May 22-28, saw the Wärtsilä engine run continuously for several days in gas mode with a series of automated changeovers from diesel mode to gas mode and back. The engine was also run at a range of load points in gas and diesel mode to exploit the sea margin of the Ternsund following a new hull that has not been impacted by fouling.
All aspects of the trials have successfully passed according to AVIC Dingheng Shipbuilding.
The engine and the X-DF technology enable the ship’s compliance with nitrogen oxides (NOx) ECAs to Tier III limits in gas operation without the need for additional exhaust gas after treatment.
The solution is the result of the “Into the Future – Baltic SO2ultion” project that aims to drive cooperation between Terntank, Wärtsilä, WinGD, fuel & bio products supplier North European Oil Trade (NEOT) and energy & environmental consultant Wega Enviro. This European Union co-funded product promotes more environmentally friendly ways of shipping in the Baltic and encourages more efficient shipping.
The chemical tanker is due for delivery at the end of June.
