Under a Memorandum of Understanding signed on the latest SMM occasion, MAN Energy Solutions and ABB are to collaborate to develop of a next-generation Dual-Fuel, Electric+ (DFE+) propulsion idea for LNG carriers.
The DFE+ idea options the just-launched MAN 49/60DF engine and ABB’s Dynamic AC (DAC) know-how. It goals to ship the operational flexibility shipowners want to chop LNG carriers’ carbon footprints in addition to gas payments for liquefied pure fuel carriers.
The scope of the collaboration covers a joint idea examine between the companions, sharing technical knowledge, and discussing interfaces and system integration. MAN Energy Solutions and ABB intend to collectively promote the idea to prospects.
Dual-fuel engines have constantly provided shipowners a excessive effectivity path to cleaner gas alternate options whereas additionally retaining the pliability to change to traditional fuels as required. MAN’s newest 49/60DF four-stroke engine can run on LNG, diesel, biofuel blends and artificial pure fuel to supply gas flexibility on the trail to decarbonization.
OPTIMIZED FUEL CONSUMPTION
In ABB’s Dynamic AC idea, {the electrical} system combines the deserves of typical AC with the variable frequency which might regulate generator load to engine speeds, optimizing whole gas consumption constantly. Installing an vitality storage resolution within the energy plant may even add to improved gas effectivity.
“Progressive regulations on emissions have called for continuous innovation in marine propulsion,” stated Rune Lysebo, world head of gross sales at ABB Marine & Ports. “To be truly future-proof, ships that are being built today need to be able to rely on flexibility in energy sourcing. The new power and propulsion system will be optimized for efficiency and compliance, and have the flexibility needed to achieve best performance.”
REDUCED METHANE SLIP
“Customers demand efficient and flexible propulsion concepts so they can react quickly to changing market conditions through the best use of their assets,” stated Elvis Ettenhofer, head of marine four-stroke – area Asia Pacifica at MAN Energy Solutions. “This cooperation with ABB will deliver the technology necessary to provide a new propulsion concept. In turn, this will help our customers to reduce their CO2 footprint and fuel costs, and will provide the flexibility, for example, in operation for different trades or retrofits from an LNG carrier to floating storage units or floating storage regasification units. This concept can reduce methane slip and fuel costs compared to conventional diesel electric propulsion systems. ABB’s DAC and global presence are an ideal match for our new four-stroke engine.”
The new propulsion resolution for LNG carriers may even be appropriate forFSUs (Floating Storage Units) and FSRUs (Floating Storage and Regasification Units).
A mixed dual-fuel electrical energy and propulsion system may very well be put in with an vitality storage resolution to reinforce load administration, or come coupled with ABB’s Azipodelectric propulsion.
MAN and ABB may even discover integrating gas cells because the know-how matures.
