The world's first X-DF powered 15,000DWT Chemical Tanker “Ternsund”.

23 June 2016

The first dual-fuel two-stroke engine employing the low-pressure X-DF gas admission technology developed by Winterthur Gas & Diesel (WinGD) has passed the final milestone in its evolution from a technical concept to commercial operation as a marine main engine. The 5RT-flex50DF engine employing X-DF technology is installed as the main engine driving a single propeller in the Ternsund, a low emissions 15,000 DWT chemical tanker.

Rated with a maximum power of 5850 kW at 102 rpm, the 5RT-flex50DF engine was run continuously for several days in its gas mode and a series of automated fuel changeovers from diesel mode to gas mode and back were executed. (Video copyright: AVIC SHIP)
