Danfoss Mobile Electrification delivers market leading efficiency for new Damen Shipyards vessel
Our client Danfoss Mobile Electrification, formerly Visedo, has successfully designed and delivered two Danfoss permanent magnet electric motors (EM-PMI) with synchronous reluctance-assisted technology for Veth Propulsion, based in Papendrecht, The Netherlands. Both the liquid cooled Danfoss EM-PMI Motors with synchronous reluctance-assisted permanent magnet technology have been combined with Veth’s technology to create the first Veth Integrated L-drive, for Damen Shipyards’ Volt Processor, a fish farm service vessel.
The new electric motor – the most compact on the market today – is half the size of conventional induction models. This lighter motor and its improved overall efficiency has helped reduce both fuel and running costs, which significantly shortens the payback period. The Danfoss Permanent Magnet (PM) Motor improves the efficiency especially when the vessel is running at average speed – so not at maximum power but rather at part load – which is typically the working speed of most vessels.
Martin van der Jagt, General Sales Manager at Veth Propulsion said:
“The new vessel we have delivered to Damen Shipyards is the best on the market and the Danfoss motors we added into the Integrated L-drive are a key part of this. The successful sea trial in April 2018 of the new fish farm service vessel confirmed that the technology we have delivered is the best around, and this is evidenced by the five percent efficiency improvement. The diesel-electric configuration provides an efficient, flexible power supply for the 750 kW propulsion installation and for driving the deck equipment when moored within a salmon farm.”
Aside from the smaller size, the other important advantages of the Veth Integrated L-drive are the hydro-dynamical design and efficiency. The liquid-cooled Danfoss PM Motor is more efficient and quieter than air-cooled asynchronous motors. The Danfoss EM-PMI motor has been designed to improve the whole operational duty cycle of the vessel; this means the exact power can be provided for both long and short movements, and different speeds and payloads. The focus on providing very smooth torque means the motor operates with extremely low vibrations and noise.
Kimmo Rauma, Vice President at Danfoss Mobile Electrification said:
“Danfoss’ close working relationship with Veth Propulsion enabled the successful delivery of the Danfoss EM-PMI Motors. The addition of this technology to create the Veth Integrated L-drive has enabled the delivery of a lighter vessel that is a significant five percent more efficient for Damen Shipyards; and the saving also enables a very short payback time.
We look forward to continuing our close working relationship with Veth, and the successful delivery of three further projects in total this year. We are also working to supply our proven Danfoss EM-PMI Motors to the wider marine market so that more vessels can benefit from the same improved efficiencies and fuel savings.”
Danfoss Mobile Electrification specializes in hybrid and electric powertrain systems for off-highway and marine markets. A business division of Danfoss, it develops and manufactures high-performance power systems for heavy-duty vehicles, machines and marine vessels, based on its unique synchronous reluctance assisted permanent magnet (SPRM) technology. Danfoss Mobile Electrification powertrains deliver market-leading efficiency and are suitable for hybrid and electric applications within the power range of 30kW to 2,000kW.
Based in Lappeenranta, Finland, Danfoss Mobile Electrification has assembled an award-winning team to work on the technologies that will enable the world of tomorrow to do more with less.
Editron is the new name for the complete electric drivetrain system developed by the company. It is controlled by powerful software that optimizes each individual component of the electric or hybrid drivetrain, leading to far more intelligent management of power distribution in order to deliver maximum efficiencies for the end user.
