Danfoss Editron provides power to electric vessel

Danfoss Editron has been chosen by Sea Forrest Power Solutions Pte to provide the drivetrain system for Singapore’s first plug-in parallel hybrid-electric fast launch vessel.

The design, development, construction and delivery of the vessel involved aluminium boat builder Penguin International, who built and owns the vessel, battery manufacturer Durapower Technology and marine class Bureau Veritas.

The vessel will support Singapore’s push for greater adoption of hybrid-electric propulsion systems in its maritime industry and the scope of the project included the design, integration, testing and certification of the vessel’s hybrid-electric systems and technology.

The 15m vessel will be used to transport personnel to an integrated oil and petrochemicals refinery, with a capacity of 12 passengers and two crew members. When operating in hybrid mode, the vessel will be able to travel non-stop for 24 hours between 5-20 knots. It will also be capable of operating in fully-electric mode at 7 knots for approximately 20-25 minutes. Depending on the method of operation, the vessel is expected to save between 10-20% in emissions compared to a similar traditional diesel vessel, or the equivalent of 81-163 tonnes annually.

Danfoss Editron’s hybrid-electric drivetrain system comprises two motors, four inverters and an inductor. SFP has developed the vessel’s power management system and Human Machine Interface, which is integrated with and controls Danfoss Editron’s power drive train, the hybrid gearbox, and Durapower Technology’s energy storage system.

Barry Yung, Danfoss Editron’s sales director in Asia, said: “Our marine system is the most compact product on the market, a critical asset in a small vessel where space and weight are very limited. Our technology also guarantees the highest efficiency, adding value to hybrid operation when shore charging is not possible. These primary technical advantages, along with our strong industry track-record and global presence, are why SFP selected our products for this project.”

George Lee, CEO of SFP, said: “In our course to deliver both environmentally sustainable and decarbonising solutions to the marine and offshore sector, we have been relentlessly searching for marine-certified, highly energy efficient electrification equipment for years. Today, our integration of the highly efficient power drivetrain from Danfoss Editron offers a supreme decentralised DC power management system, a benchmark for future marine vessels in Singapore featuring hybrid or electric propulsions.”

Vincent Lim, Chief Executive Officer of BH Global, added: “It was a great honour to work with Danfoss Editron and all the project partners on this project. This collaboration is a significant milestone towards achieving our goal of delivering environmentally-friendly and commercially-viable electrification solutions for the local maritime industry. It will also enable us to make a positive contribution to Singapore’s push towards reducing carbon emissions in its local maritime operations.”
