As the industry shifts towards alternative fuels in response to environmental regulations and sustainability goals, the safety risks associated with these fuels cannot be overlooked, says the International Association of Classification Societies (IACS). Crankcase explosions, a critical hazard in engine operation, becomes even more concerning in the context of gas and low flashpoint fuels. IACS has therefore published the latest edition of Unified Requirement (UR) M10, which introduces…

Vessel owners are making new fuel choices, but increasingly, they have options to help reduce the risk of doing so.The latest engine developments aim to make it easier for owners to avoid the chicken-and-egg fuel price and availability risks of new fuels.As Roger Holm, President of Wärtsilä Marine and Executive Vice President at Wärtsilä Corporation recently pointed out, the challenge is that owners won’t commit to a fuel today that is expensive, only produced in small quantities and may be usurped by another fuel that scales faster and more affordably.

Ships trials reportedly confirmed that CM Technologies’ new scuffing sensor can detect early onset cylinder wear in marine diesel engines. Trials onboard a number of large containerships and a two-stroke engine Baltic ferry showed it was possible to measure the friction in the cylinder when the engine is running.CMT noted a trend in cylinder liner scuffing following the widespread use of 0-0.50% low sulphur fuel (LSF). These fuels together with insufficient or over lubrication…

On October 1, 2024, NYK began operation of a test engine facility in Chiba Prefecture to evaluate the safety of new fuels.The introduction of new marine fuels used to necessitate testing and analysis at external engine facilities, in addition to trial operations, all of which would require about two years to complete. Shortening this period and reducing the cost of testing have been key to meeting the increasing demand for new fuels, such as biofuels, and satisfying the environmental regulatory measures of various countries.

The Maersk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) has released a new report: Tackling methane slip in shipping.Past research at the MMMCZCS has demonstrated that current regulations that include methane, such as CO2-equivalent fuel standards (e.g., FuelEU Maritime), will have a limited effect on reducing onboard methane emissions in the short- to mid-term. Furthermore, the default methane slip value concept does not provide a direct incentive to engine makers…
