Confusion over new fuels will not be helped by the fact that each one has a good and bad version. The science on grey ammonia, grey methanol, and palm oil biofuel show that these are probably worse for the planet, if adopted, than unfettered continuation of fossil fuel consumption. Conversely, green methanol, green ammonia and biofuel made using genuine wastes and residual products could create a substantial dent in production and consumption of fossil fuels. For this reason, clarity on which fuels shipping lines intend eventually to use is vital.Höegh Autoliners is set on ammonia…

MAN Energy Solutions will deliver the world's most powerful two-stroke methanol engine in June 2025. The engine, an MAN B&W 12G95ME-C10.5-LGIM (-Liquid Gas Injection Methanol) type rated at 82,440 kW @ 80rpm, is currently being built by Chinese licensee, CSSC-MES Diesel Co., Ltd. (CMD).The engine is the first of 12 bound for a series of 12 × 24,000 teu container vessels currently under construction: seven at Nantong COSCO KHI Ship Engineering Co., Ltd. (NACKS) for shipowner, Orient Overseas Container Line Ltd. (OOCL); and five at Dalian COSCO KHI Ship Engineering Co., Ltd.

If the dynamic positioning (DP) system went down on an offshore supply vessel, it could result in a collision. On a dive support vessel, it could result in injury or death for a diver. On a drilling rig, it could result in a blowout with loss of life, pollution and fire.Built-in redundancy is key to avoiding failures, and this in turn determines the thruster, electrical and engine configurations that are designed to enable DP systems.“There is no single, universal solution,” says Lauri Tiainen, Director Thrusters and Propulsion Control Systems, Wärtsilä Marine.

Cummins received Approval in Principle (AIP) from DNV for its methanol-ready QSK60 IMO II and IMO III engines, available in power ratings from 2000 to 2700 hp (1491 - 2013 kW).

In the ever-evolving quest for cleaner, more efficient energy sources in maritime vessel operations, nuclear power has re-emerged as a topic of serious discussion, as shipowners eye the International Maritime Organization push to ‘net zero’ on or around 2050. Admittedly, there is no ‘silver bullet’ solution for the entirety of maritime premised on the wide variety of routes and ship types, but nuclear holds promise in several large-ship, oceangoing sectors. Phil Lewis, Director of Research at Intelatus…

The maritime industry’s elusive quest to achieve so-called ‘zero’ emissions continues. Where it ends is not a one-size-fits-all discussion.The year-end maritime industry discussions tend to move away from global influence and back drift to national and domestic debates. As this happens, a positioning of a relatively small group of American owners and operators prepare for the upcoming business year and markets. The propulsion debate continues to be future fuels based upon sustainability and climate change.
