Aspin Kemp and Associates Inc. (AKA) and MAN Energy Solutions (MAN) are working together on the delivery of the propulsion package for 1+1 230-meter-long RoPax vessel for TT-Line, a German ferry operator

The vessel is to be built at Jiangsu Jingling shipyard in China. The MAN/AKA power and propulsion package includes eight MAN 51/60DF dual fuel engines, propellers and gearboxes, a fuel-gas supply system and HyProp ECO – a hybrid propulsion system. The newbuild TT-Line ferry will have the capacity for 800 passengers and over 200 articulated trucks. 

The newbuild 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 vessel will have 50% fewer emissions than TT-Line’s previous generation of vessels.

AKA’s main scope of supply includes the propulsion AC switchboards, distribution transformers, electric bowthruster motors and PTO shaft generators, bow thruster frequency converters, drive control and power management systems. Five different modes of operation for the shaft alternator will be provided which enable fuel-saving power generation in combination with a smart and flexible supply of the bow thrusters during challenging maneuvering situations.

In 2017, AKA and MAN formalized its partnership through MAN’s acquisition of 40% of the innovative power and propulsion system supplier AKA.
