Marinvest dual-fuel pair clock up 10,000 hours operating on methanol

The <i>Mari Jone</i>, powered by MAN B&W ME-LGI dual-fuel engine and running on methanol, was launched in 2016. The Mari Jone, powered by a MAN B&W ME-LGI dual-fuel engine and running on methanol, was launched in 2016.

Marinvest, the Swedish ship-management company, stated that two of its vessels, Mari Jone and Mari Boyle, have each passed 10,000 operating hours operating on methanol.

Marinvest added that its fleet had recorded over 50,000 hours of cumulative experience operating on methanol.

The vessels are managed on timecharters for Waterfront Shipping and operate globally, providing an uninterrupted flow of methanol between storage terminals and customer plants. The Mari Jone and Mari Boyle were delivered in 2016, and were among the first ME-LGI vessels operating on methanol to enter service.

Bjarne Foldager – Senior Vice President, Head of Two-Stroke Business at MAN Energy Solutions – said: “The successful passing of this significant milestone is testament to the ME-LGI’s strong concept, and indeed the strength of our dual-fuel portfolio as a whole. With well over 250 sales within MAN Energy Solutions’ entire portfolio of low-speed, dual-fuel engines – all running on clean fuels such as methanol, LPG or LNG – this new achievement stands testament to our leadership within a critical market segment.”

René Sejer Laursen – Sales & Promotion Manager, MAN Energy Solutions – said: “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 behaviour. 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.”
