Yanmar dual-fuel engines for shipboard generators

Engines can run on LNG or diesel
Yanmar has received an order for dual-fuel 6EY22ALDF engines which will be used to power generators on board a liquefied natural gas (LNG)-fueled large coal carrier.
The company said emission regulations in the marine sector are becoming ever more stringent, with LNG vessels being adopted globally as a means of reducing environmental impact. As this trend has progressed in recent years, dual-fuel engines have attracted ever more attention. Their ability to run on both diesel and environmentally friendly LNG allows them to satisfy International Maritime Organization (IMO) Tier 3 regulations whilst also reducing greenhouse gas (GHG) emissions, Yanmar said.

The coal carrier will be operated by Mitsui O.S.K. Lines and be built by Namura Shipbuilding Co.
The 73 L 6EY22ALDF engine is rated 800 kW and has a bore and stroke of 220 X 320 mm.
