China’s Jinling Shipyard has ordered four MAN 51/60DF engines for a 230 m RoPax it is building for German ferry operator TT-Line under a contract that contains an option for a second vessel.
With a capacity for 800 passengers and 200 trucks, the ship will be LNG fueled and will have a complete MAN propulsion package that, in addition to the engines will include propellers, a fuel-gas-supply system (FGSS), and HyProp ECO – MAN’s innovative, fuel-saving, hybrid propulsion system.
The newbuilding is based on TT-Line’s “Green Ship” design, developed in collaboration with Copenhagen-based designer, OSK-Shiptech, and is scheduled for delivery in 2022, when it will enter service on TT-Line’s route network in the Baltic Sea. Operating on LNG, the new vessels will have 50% fewer emissions than TT-Line’s previous generation of vessels.
“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,” said Lex Nijsen, Head of Four-Stroke Marine Sales – MAN Energy Solutions. “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.”
The MAN Energy Solutions will provide its scope of supply for the vessel in association with Aspin Kemp & Associates (AKA), in which it has a 40% stake. AKA specializes in power supply, energy management and drive systems for marine and industrial applications.
Similarly, MAN Energy Solutions’ fuel-gas specialist – MAN Cryo – will supply the new vessel’s fuel-gas-supply system. MAN Cryo offers systems for the storage, distribution and handling of liquefied gases and was fully integrated into the company in 2015.
“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,” said Nijsen. “It also fulfills our desire to increasingly become a supplier of complete solutions.”
MAN Energy Solutions’ scope of supply covers:
- 2 × 8L51/60DF + 2 × 6L51/60DF MAN engines offering a total power of 29,400 kW
- MAN Alpha twin-screw CPP propellers
- 2 × twin-in, single-out gearboxes
- MAN Cryo FGSS featuring 2 × 500 sq. m vacuum insulated Type-C tanks
- AKA’s advanced HyProp ECO system
- AKA drives, electric generators and motors for the PTO and bow thrusters.
HyProp ECO is a system solution that combines a diesel engine with a frequency-converter-driven shaft-alternator/motor and features multiple operational modes. The system combines the advantages of a bi-directional operating frequency converter for the shaft machine with a high-efficiency CP propeller plant. HyProp ECO is also open for shore connection and the integration of energy-storage devices/batteries.
