Capable of transporting up to 299 passengers and 20 bicycles at speeds of up to 28 knots, the new vessel has been designed for safe, comfortable, and highly reliable commercial rapid transit ferry services. The passenger experience has been enhanced via the inclusion of a range of seating options – including tables and USB ports for those that need to work on their commute, fold-up luggage compartments and floor-to-ceiling windows.
The vessel’s drivetrain includes four Danfoss EM-PMI540-T4000 electric motors, Hamilton HTX42 water jets, and state-of-the-art hybrid electric systems. Incat Crowther has utilised cutting-edge digital shipbuilding technology in designing the support systems for the electric propulsion system.
This includes liquid cooling systems featuring pumps and heat exchangers for e-motors, converters, inverters and switchboards, and chillers for batteries. The design also features electrical equipment and cable route arrangement to minimise electromagnetic interference, the selection and integration of fire suppression systems, and battery room ventilation systems. Weight control for such expansive systems has been critical, with each item weighed and tracked throughout construction.
The vessel’s drivetrain features the ability to employ a pair of range-extending generators that can be used in conjunction with the battery bank. This technology supports electrification and the reduction of emissions whilst delivering on timetable and range requirements. The new vessels are also future-proofed and can be refitted to operate on hydrogen fuel for increased range in the future.
The new vessel will contribute to Auckland Transport’s mission to modernise and decarbonise the city’s ferry fleet. The vessel is expected to reduce carbon emissions by 750,000kg per year.
