MAN Engines Powering RoRo Vessels

Posted on March 8, 2011

DFSD, the Danish shipping company, has signed a contract for the construction of two identical RoRo vessels, each of which will be powered by two MAN B&W 8S40ME-B9 engines.

The vessels will employ a twin-screw propeller system using the Alpha Mk. 5 designs – type VBS1350FF-ODS. The FF-type propeller incorporates a full feathering pitch position and employs the Alphatronic 2000 as its propulsion control system. The propulsion package also uses shaft-line tunnel gears for the PTO drive. DFDS also selected 3 x MAN Holeby 16/24 generator sets for each vessel.

The ships’ design is tailored towards operation on DFDS’ commercial network, but will also meet the parameters from the Danish-German ARK military project for the deployment of military material. The propulsion plant is designed for operation in several modes, such as cruising, maneuvering and economy for military convoy sailing, with an electrical system that can handle fixed and floating frequencies, DFDS said.

The vessels will be built at the P+S Werften shipyard in northern Germany, and are expected to enter service on one of DFDS’s North Sea routes with an ordinary service speed of 18.6 to 18.7 knots and a contractual speed of 20.5 knots. When deployed for military service and convoy sailing, the speed will be reduced to about 12 knots.
