DNV-GL passenger ferry NB series

aluminumhybrid

Overview
Norwegian operator Boreal has contracted Sefine Shipyard to build five sister hybrid double-ended ferries (NB46 / NB50 series) for inner-fjord commuter routes. Each vessel is a fully aluminium, 35.00 m double-ended ferry designed by Multi Maritime with a 1017 kWh battery system integrated by WESTCON P&A. These ferries increase passenger capacity compared with the existing vessels serving the Oslofjord islands.

Operational context and suitability

• Intended for short inner-fjord commuter and island services where double-ended operation reduces turnaround and berthing time
• Hybrid system enables battery-electric operation for parts of the route to reduce fuel consumption and local emissions
• Aluminium hulls support weight reduction and efficient draft for sheltered coastal waters
• Suitable for operators seeking increased passenger capacity compared with previous Oslofjord vessels
