MAN PROPULSION PACKAGE FOR BALTIC LNG-FUELLED RO-PAX NEWBUILD

Monday, May 20, 2019 

The Jinling Shipyard in China has ordered four MAN 51/60DF engines in connection with a ro-pax vessel contract for TT-Line, the German ferry operator.

The order is for one shipset, with an option for a second. The vessel will feature a complete MAN propulsion package, besides the engines, including propellers, a fuel-gas-supply system (FGSS), and HyProp ECO – MAN’s innovative, fuel-saving, hybrid propulsion system. HyProp ECO combines a diesel engine with a frequency-converter-driven shaft-alternator/motor and features multiple operational modes.

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, whereupon it is expected to enter service within 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.

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 Aspin Kemp & Associates (AKA), in which it has a 40% stake. AKA specialises 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.

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.

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
  • An MAN Cryo FGSS featuring 2 × 500-m2 vacuum insulated Type-C tanks
  • AKA’s advanced HyProp ECO system
  • AKA drives, electric generators and motors for the PTO and bow thrusters.

In respect to the last point, five different operational modes for the shaft alternator (PTO) will enable fuel-saving power generation in combination with a smart and flexible supply for the bow thrusters.
