Type Approval Test Milestone For Two Stroke Duel Fuel Engine

The first dual-fuel two-stroke engine, equipped with a low-pressure gas admission system, has successfully completed its Type Approval Test (TAT).

The TAT was carried out on a 5 cylinder 500mm bore Wärtsilä engine (the RT-flex50DF) and features WinGD’s dual-fuel technology, which is referred to as X-DF.

Mr. Marcel Ott, General Manager Dual-fuel Technology at WinGD’s headquarters in Winterthur, Switzerland, commented:“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.”  

The Wärtsilä engine reduces sulphur oxides (SOx) and particulate matter emission levels very close to 0%. NOx emissions are reduced to at least 85% below the levels demanded by the International Maritime Organization (IMO) Tier III requirements, and CO2 emissions are 25% lower compared to engines running on diesel fuel.

The two-stroke engine will be delivered to the shipyard this month in preparation for installation on a 15,000 DWT tanker ordered by Terntank Rederi A/S, and is the first of four.  The tankers will operate largely in northern European sulphur Emission Control Areas (ECAs).

This engine is also a central element in the ‘Into the Future – Baltic SO2ution’ project, an EU-supported Joint Industry Project (JIP) that aims to improve the environmental compatibility of energy transportation in the Baltic Sea.
