Type approval for Wartsila dual-fuel two stroke

The TAT of the Wartsila brand engine took place at the works of WinGD’s Chinese licensee Yachai Mairne Power Co Ltd. (YCMP) in early December 2015.

“The successful TAT is proof that WinGD low-pressure X-DF Technology is not only commercially competitive, but also fulfils all the safety standards required,” said Marcel Ott, general manager of dual-fuel technology at WinGD’s Swiss headquarters.

He added: “At the same time, the adoption of the RT-flex50DF engine for the Baltic SO2lution shows that the technology is already acknowledged as a very environmentally friendly propulsion option.”

The approval was witnessed by representatives from major Classification Societies, such as ABS, BV, CCS and DNV-GL.

With the TAT successfully completed, the WinGD low-pressure dual-fuel technology is now fully ready for commercial use in marine propulsion applications.

This particular YCMP-built 5RT-flex50DF engine will be delivered in January 2016 to the shipyard building four 15,000 DWT tankers ordered by Tarntank Rederi A/S, based in Skagen, Denmark.

The tankers will operate mostly in northern European waters designated as Sulphur Emission Control Areas (SECAs).
