Italian Visemar's new RoRo (construction at Cantiere Navale Visentini yard, near Venice) will be powered by twin MAN engines.

The vessel will be powered by a complete MAN propulsion package featuring 2 × 9L32/44CR medium-speed engines., which each develop 5,040 kW at 750 rpm and are complemented by 2 × Renk RSV 900C gearboxes and 2 × Alpha CPP propellers. The engines fulfill IMO Tier II regulations and will be built at MAN Diesel & Turbo’s Augsburg works in Germany from where they are scheduled for delivery in August 2013.

The newbuilding is scheduled to follow in April 2014 and, having already been granted a ‘green passport’ and green star certification, will be one of the most efficient and environmentally friendly vessels in its class.


Visemar wanted a ship that delivered the best efficiency and fuel consumption in its class, and accordingly decided upon an entire MAN Diesel & Turbo package. Sokrates Tolgos – MAN Diesel & Turbo – Head of Cruise & Ferry Sales said: “This MAN propulsion system with common-rail engines gives the customer a perfectly synchronised, high-efficiency solution. The engines’ common-rail fuel injection, with its high flexibility, is central to their meeting Tier II exhaust-gas requirements at the lowest possible fuel-consumption, especially in part load.



Tolgos continued: “Another important benefit is the engines’ unmatched performance in terms of minimum smoke emissions, even with lower-quality fuels like HFO. We are very pleased that Cantieri Navali Visentini and shipowner Visemar, two long-standing customers of MAN Diesel & Turbo, expressed their confidence in our company by asking us not only to supply the engines but, additionally this time, the complete propulsion package including MAN Alpha CP propellers.

"

Propulsion package

MAN Diesel & Turbo optimised the propulsion system in close cooperation with the Cantieri Navali Visentini shipyard and NAOS, the Italian RoPax/RoRo ship-design specialist. The MAN Alpha CP propellers stem from the new HUB Mark 5 series,
which – courtesy of a project-specific special propeller-blade design – deliver a very high propulsive efficiency, leading to substantial fuel-oil savings for the complete propulsion plant. Similarly, the Renk gearboxes work with very low friction, incurring fewer losses and a higher efficiency.
