Fuel flexibility may be a key driver for recent developments in gensets, but the perennial goals of lowering CapEx and OpEx remain.Fuel flexibility is one of the pillars of decarbonization that is being embraced by genset OEMs. Fuel efficiency, a second pillar, goes hand in hand with that because new fuels will be more expensive, but these concerns come in addition to the on-going drive to reduce CapEx and OpEx for shipowners.MAN Energy Solutions introduced its auxiliary MAN 35/44DF CD engine in June 2023. It is designed to be future-proof and will be ready for methanol operation by 2026.

The quest to build a series of five National Security Multi-Mission Vessels (NSMVs), which will serve as training ships for five U.S. maritime academies, has drawn a broad cadre of suppliers. The powerplant was a main focus, helping to evolve the schools from steam power plants to a modern propulsion package.NSMVs being built for the maritime academies is widely lauded as a ‘win’ for U.S. shipbuilding, an example of commercial shipbuilding practices applied to a government shipbuilding project.

There are vessels on order today—including crew transfer vessels (CTV) being built in the U.S. (American Offshore Services at Blount Boats and for WINDEA CTV at St. Johns Ship Building and Gulf Craft, for example)—that are described as “hybrid-ready”. Of course, a vessel is either hybrid or it isn’t. So what does hybrid-ready mean?When asked about the hybrid-ready CTVs that Blount Boats is building, the shipyard’s president Marcia Blount told Marine News that the vessels’ Volvo Penta IPS propulsion system “is readily upgradeable to hybrid at any time in the future.

A well-built, modern vessel can be expected to outlive her original engines. The challenge for those representing the owners, is to choose new engines that match or exceed the capabilities of the original power. Consideration will be given to replicas of the original engines. However, availability and suitability may limit this.These were some of the considerations confronting the Thai Marine Department when they decided to put their 41.85 by 3.9-meter oil response vessel back into service.

There's an “electrification of the seas” happening for navies around the world.Whether it's to achieve greater military capabilities, operational economics and efficiencies or to be better stewards of the environment.There's a trend moving from direct mechanical drives towards more flexible electrical propulsion systems. Ships can still have the same propellers and engines, but they now have a much more flexible power system architecture that benefits design, operations and sustainment.“With an electric propulsion system, we can connect to the same gas turbine or diesel.
