MAN DF propulsion for LNG RoPax newbuild
The vessel will feature a complete MAN propulsion package, besides the engines, including propellers, a fuel gas supply system (FGSS), as well as HyProp ECO – MAN’s innovative, fuel-saving, hybrid propulsion system.
The newbuilding is scheduled for delivery in 2022, when it is expected to enter service within TT-Line’s route network in the Baltic Sea. Operating on LNG, the new vessels – based on TT-Line’s ‘Green Ship’ design, developed in collaboration with Copenhagen-based designer, OSK-Shiptech – will have 50% fewer emissions than TT-Line’s previous generation of vessels.
The vessel’s propulsion plant features 2 x 8L51/60DF and 2 x 6L51/60DF MAN engines offering a total output of 29,400 kW. Drive is to MAN Alpha twin-screw controllable pitch propellers.
The package includes Aspin Kemp & Associates (AKA) drives, electric generators and motors for the power take-off (PTO) and bow thrusters. In respect to the last point, five different operational modes for the shaft alternator (PTO) will enable a fuel-saving power generation in combination with a smart and flexible supply of the bow thrusters.
Lex Nijsen, Head of Four-Stroke Marine Sales – MAN Energy Solutions, said: “Running on LNG, our propulsion package will enable this vessel to operate on such low emissions that it will become the most environmentally friendly RoPax ferry in the Baltic. Our business, to a great extent, is based on offering systems such as this that help our customers to increase the efficiency of their plants and reduce emissions, while leading the way to a carbon-neutral future.”
MAN Energy Solutions will provide the scope of supply in association with AKA, in which it has a 40% stake.
Nijsen added: “This order is the very first MAN dual-fuel, diesel-mechanical propulsion system for a ferry application, which reflects our strategic direction of developing sustainable technologies and solutions – as shown by the contribution of AKA and MAN Cryo. It also fulfills our desire to increasingly become a supplier of complete solutions.”
Upon construction, the newbuilding will have the capacity for 800 passengers and over 200 articulated lorries. While designing the vessel, a particular emphasis was put on flexibility and fast, in-port turnaround-times. TT-Line currently has six ferries operating on various routes in the Baltic Sea.
