Terntank's dual-fuel-powered chemical tanker (ship-type shipyard) "Ternsund" successfully passed the sea trial not long ago, marking the entry of Wärtsilä (ship hangar)'s dual-fuel two-stroke engine (product library supply) The market has completed the final step.
     According to the construction of the shipyard Zhonghang Dingheng (Location Review News) shipbuilding, the "Ternsund" oil tanker is 15,000 dwt, with a total length of 147 meters, a width of 22 meters and a design speed of 14.5 knots. It is the first of a series of four sister ships. The ship is equipped with a 5-cylinder 500 mm cylinder Wärtsilä RT-flex 50DF with a maximum power of 5,850 kW / 102 rpm. During the sea trial, the aircraft was operated in gas mode for several days, during which time it was switched to diesel mode several times. Both modes were operated at high load and all tests were successfully completed.
     This engine is the first dual-fuel X-DF series machine for commercial applications. It is developed by low-pressure gas injection and is developed by Winterthur Gas and Diesel (purchasing supply). It was moved by Yuchai in October 2015. Ship hangar location) The company delivered to the shipyard.
