NSD 85 CFd ferry: hybrid architecture designed for full electrification upgrade path
Construction has officially commenced on a new passenger-car ferry of the NSD 85 CFd type, developed under the design supervision of Remontowa Marine Design & Consulting. The vessel represents a transitional yet future-proof approach to short-sea shipping decarbonisation.
In brief
Remontowa Marine Design & Consulting has begun construction of an NSD 85 CFd passenger and car ferry with a length of 83.5 metres and a beam of 17.25 metres. The NSD 85 CFd ferry will carry 253 people, 85 passenger cars and 6 trucks, with a service speed of 12 knots and a deadweight of 650 tonnes. Propulsion consists of two azimuth thrusters with permanent magnet electric motors and four generating sets running on 100% biodiesel. The design provides for expanding the battery system to up to about 15 times its capacity, which will enable fully electric operation.
Hybrid propulsion concept
The propulsion system is based on two azimuth thrusters driven by permanent magnet electric motors. Electrical energy is supplied by four generator sets operating on 100% biodiesel.
This configuration allows for flexible load management and ensures that generating units operate within optimal efficiency ranges, resulting in reduced fuel consumption and improved overall energy performance.
Battery system as peak-load support
A dedicated onboard energy storage system has been integrated to handle peak power demand. By smoothing load fluctuations, the batteries enable the gensets to maintain stable and efficient operation.
Importantly, the design already incorporates a scalable architecture, allowing for a future upgrade of the battery capacity by a factor of approximately 15. This would enable full electric operation under suitable operational profiles.
Designed for future energy transition
Rather than being a static hybrid solution, the NSD 85 CFd has been conceived as an adaptable platform. The vessel is structurally and electrically prepared for progressive electrification, aligning with long-term regulatory and environmental trends in European ferry transport.
Principal particulars
The ferry measures 83.5 metres in length and 17.25 metres in beam, accommodating up to 253 passengers and crew, 85 passenger vehicles and 6 trucks. Service speed is 12 knots, with a deadweight of 650 tonnes.
