Rolls-Royce to deliver propulsion for new Danish passenger ferry
Danish ferry operator Mols-Linien has ordered a new passenger ferry from the Rauma Marine Constructions yard in Rauma, Finland.
Rolls-Royce will provide the main propellers and propulsion control system to the new ship, which is planned to operate between mainland Denmark and the island of Bornholm, also known as the sunshine island of the Baltic Sea.
Rolls-Royce will deliver two units of a Promas system which integrates the controllable pitch propeller, a propeller hub cap, a rudder with bulb and a twisted leading edge into one hydrodynamically optimized unit. Gearboxes, steering gears, two tunnel thrusters in the bow and a control system are also part of the delivery.
Included in the order are cavitation tests at the Rolls-Royce Hydrodynamic Research Centre (HRC) in Kristinehamn, Sweden. At this advanced facility, the performance of the combined propeller and rudder system (Promas) will be controlled and tested prior to manufacturing. The HRC includes a large cavitation tunnel where a model of the ship’s hull, with the ordered propulsion set up, will perform in different operating conditions. Model testing can lead to important and cost-saving adjustments in a product or ship design.
The Rolls-Royce Hydrodynamic Research Centre is one of the world’s leading marine research facilities, specialising in the development of marine propulsion systems including the design and testing of propellers and water jets.
The new passenger ferry for Mols-Linien will have a capacity of 600 people and two decks totalling 1,500 lane metres for transportation of cars and trailers. It is planned to enter operation in September 2018.
