Jinling Shipyard in China orders 4 × MAN 51/60DF engines for Baltic RoPax newbuilding
The Jinling Shipyard in China has ordered 4 × MAN 51/60DF engines in connection with the building of 1 + 1 × 230-metre-long RoPax vessels for TT-Line, the German ferry operator. 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.
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.
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-m3 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 a fuel-saving power generation in combination with a smart and flexible supply of the bow thrusters.
About HyProp ECO
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.
The new TT-Line order is part of the ‘Maritime Energy Transition’, an umbrella term that covers all MAN Energy Solutions activities in regard to supporting a climate-neutral shipping industry.
The term stems from the German expression ‘Energiewende’ and encapsulates MAN Energy Solutions’ call to action to reduce emissions and, among other initiatives, establish natural gases as the fuels of choice in global shipping.
Launched in 2016 after COP 21, the initiative has since found broad support within the shipping industry and politics.
Based in Travemünde, Germany, TT-Line is the market leader in direct transport between Germany, Poland and Sweden, and carries nearly 900,000 passengers, 180,000 cars and more than 400,000 freight units annually. Typically, the company’s ferries transport up to 6,500 passengers daily.
