WinGD X52 passes type approval test
The latest model in Winterthur Gas & Diesel’s (WinGD) ultra-long stroke engine series, the X52, has passed type approval and factory acceptance tests at licensee Hudong Heavy Machinery’s factory in China.
The five-cylinder model of the 520mm-bore engine which passed testing was certified for Tier II NOx compliance. It will be installed on a 38,000dwt bulk carrier under construction at the Guangzhou Wenchong Shipyard (GWS) in Guangzhou. A further 13 engines on order, all six-cylinder versions to be built in Korea, include models certified for Tier II and Tier III compliance.
WinGD noted that the X52 boasts reduced fuel consumption due to a longer stroke configuration, while the relatively light structure is designed reduce maintenance costs. The engine designer’s X-prefix engines also offer dual rating: with a minimum of modifications to engine and turbocharger, operators can employ a fuel-saving slow steaming mode.
Alexander Brückl, senior project manager new engines, WinGD, explained that while a long stroke improves fuel efficiency, there are other design considerations. “Our designers were very aware that an engine’s stroke dimension has a direct effect on engine height which, in turn, has a considerable influence on engine room size and the effective payload of a vessel. We chose a larger bore diameter, and the bore-to-stroke ratio is proving to be very popular,” he said.
Of the thirteen 6X52 engines on order, six - rated 7,180kW at 86.9rpm and employing high-pressure SCR to achieve Tier III compliance - will power a series of six 49,000dwt product tankers; two Tier II compliant engines rated 7,180kW at 86.9rpm will be installed in two 50,000dwt product tankers; and five 6X52s, rated 8,200kW at 80rpm and using low-pressure SCR for Tier III compliance, will power a series of five 60,000dwt open-hatch general cargo vessels.
