The Austal shipyard in Vietnam has ordered four 16V175D-MM engines, delivering 2,720 kW at 1,800 rpm for waterjet propulsion, in connection with the building of a high-speed catamaran ferry for customer Degage Group.
The 66m, 574-passenger ferry is scheduled for delivery in the first half of 2023 and will operate as the Apetahi Express between Pape’ete (Tahiti) and Vaitape (Bora Bora) in French Polynesia. The new ferry will have a contracted top speed of 35.8 knots and a range of 360 naut miles.
Tuanua Degage, President, Degage Group, said “These will be the first MAN engines in our fleet. We are very much looking forward to working with MAN Energy Solutions, and in particular the MAN PrimeServ New Zealand team, to ensure the highest levels of engine reliability and economy on this very demanding route.”
Ben Andres, Head of High-Speed Sales, MAN Energy Solutions, said: “This is an important milestone for the MAN 175D as it wins the favour of yet another, high-speed ferry application, this time with the Degage Group, an acknowledged leader in commercial maritime transportation and tourism. The 175D has a number of advantages that make it eminently suitable for such a technically demanding application, including its long times-between-overhaul, and its best-in-class fuel consumption.”
MAN PrimeServ, MAN Energy Solutions’ after-sales division, reports that it has already established service operations in the region in Auckland, where its local hub services 175D engines in operation by the New Zealand Navy. The same hub is located conveniently for maintenance and service support of the newbuilding ferry in Tahiti.
Claimed benefits of the MAN 175D engine for highspeed ferry propulsion include:
- very long TBOs for demanding ferry operation with continuous high average load,
- most competitive fuel consumption in the 2720 kW power range, and
- lowest operating costs in class.
The MAN 175D comes in three variants of 12, 16 and 20 cylinders, with power output ranging from 1,500kW to 4,400kW and is optimised for propelling ferries, offshore supply vessels, tug boats and other working vessels. Other market areas, such as superyachts and naval marine are served by additional, specialist model versions. It is said to be an extremely eco-friendly engine, designed from the outset with compliance to the latest, as well as future, exhaust gas emission requirements and utilises a very compact and flexible SCR system, which enables vessel designers to optimise space on board to the maximum.
