Scandlines is one of Europe's largest ferry companies, a result of the merger between the largest, national ferry lines in Denmark and Germany. Business is based on the transport of both passengers and cargo on international routes within Danish, German and Swedish waters, as well as further afield to the Baltic states and Finland.

Scandlines operates 17 ferries on eight routes between eleven harbours in the Baltic Sea.

Last year, the shipping company transported more than 17.3 million passengers, four million cars, one million lorries, 84,000 goods wagons, and 68,000 buses.

"We started to look at propeller retrofit solutions as a direct consequence of high fuel prices," Rasmus Nielsen, Scandlines' Project Engineer said. "On board the 'Sassnitz', we have replaced the propeller blades with a modern, optimised design. Our tests document that this has realised an increased efficiency of no less than percent. Originally, MAN Diesel had eight to ten percent as a target."

Mr Nielsen explained that the ships are required to reverse a lot in harbour and so it was necessary for Scandlines to attain the optimal propeller blade design.

In order to optimise the process, MAN Diesel's propeller design department analysed 'Sassnitz's' operating profile. MAN Diesel PrimeServ participated in the installation of the new propeller blades on the 'Sassnitz', which is powered by four MAN L40/54 engines.
