The World’s First Methanol-Powered ships are moving towards zero-emissions

The first methanol-powered ships have already passed the 10,000 operating hours. The two eco-friendly tankers (50 000 DWT), the Mari Jone and Mari Boyle, work on the clean-burning alternative fuel.

The vessels have been in operation during three years. They were the first of seven methanol-powered ships, passed about 50,000 cumulative operating hours on methanol.

The ME-LGI engines are two-stroke dual fuel engines and can run not only on methanol, but also marine diesel oil, gas oil or fuel oil.

The shipping has faced very strict emissions requirements, and methanol is considered to be a standards-compliant clean-burning alternative fuel.

Marinvest reported, two ships, the Mari Jone and Mari Boyle, have consumed 28 287 MT of methanol, eliminating about 990 000 kg of sulphur oxide emissions.

“When introducing methanol as a two-stroke marine fuel, we encountered the usual teething problems, including addressing the liner lubrication because of methanol’s potentially corrosive behavior,” stated a Sales & Promotion Manager at MAN Energy Solutions René Sejer Laursen. “However, the service experience gathered after 50,000 hours of cumulative operation has ironed all such problems out and the ME-LGI engines are now running smoothly with no maintenance issues. In fact, they are even showing an improvement in fuel efficiency.”
