Class society Lloyd’s Register has announced Approval in Principle (AiP) for a hybrid nuclear ready power concept, developed with Australian ship design group, Seatransport, which would enable Micro Modular Reactors (MMRs) to be combined with conventional diesel-electric systems for 73-metre and 90-metre amphibious stern landing vessel (SLV) designs. The AiP is the culmination of a number of years of collaboration between LR and Seatransport, and the companies say they have now demonstrated how licensable MMRs can be safely integrated with proven diesel-electric systems to deliver long-range vessels with significantly reduced fuel dependence and emissions. A recently launched conventionally powered 73-metre […]

Mitsubishi Shipbuilding has supplied an ammonia fuel supply system (AFSS) and an ammonia gas abatement system (AGAS) for an ammonia-fuelled marine engine manufactured by Japan Engine Corporation (J-ENG). The systems are the first such units produced by Mitsubishi Shipbuilding and were designed for 7UEC50LSJA-HPSCR, the first ammonia-fuelled marine engine model manufactured by J-ENG. The AFSS will ensure the safe and stable supply of ammonia fuel to the engine, while the AGAS will process surplus ammonia generated during fuel switching. Both systems can be operated remotely with automated control to enhance efficiency and safety, Mitsubishi said in a statement on 24 […]

P&I Club NorthStandard, working with bunker supplier World Fuel and fuel testing agency VPS, has published a discussion document which looks at biofuel uptake, potential issues and loss prevention measures There is increasing uptake of fuel blends with a ‘bio’ component of 5%-10%. Last year, FuelEU Maritime regulations required ships to cut GHG intensity by 2%, with 6% mandated by 2030. However, NorthStandard highlights that with reductions to 14.5% required by 2035 and up to 80% by 2050, higher bio components will be needed. A 30%-40% bio component also aligns with the International Maritime Organization’s target for ships to cut […]
