Wärtsilä supplies propulsion package for ro-ro duo

Wärtsilä will supply the vessels with its latest propeller design, WCP G-hub, which is optimised for high power density. The propellers will be designed using the Watrsila’s Optidesign method, which uses advanced computational fluid dynamics (CFD) technology to optimise the interaction between the propeller and hull in order to reach the highest possible performance.

The scope of supply also includes the propeller shaft line system including propulsion controls, as well as a stern tube package with seals and bearings, intermediate shaft line bearings, and accessories. The Wärtsilä shaft generator system is not only able to generate power to the mains from the main engine, but is also able to function as a motor should the main engine be inoperable for any reason, thus enabling the ship to return to port.

“Wärtsilä is well established in the field of shaft generators with more than 470 systems as case references. The efficiency of our latest technology ensures both reliability and a short return on investment. We have a good relationship with the Uljanik yard and are happy to be working with them on this project,” said Peter Rogers, director, power conversion, Wärtsilä Marine Solutions.

“We very much appreciate Wärtsilä’s technological strength in controllable pitch propeller and shaft generator solutions. We also enjoy strong support from the company, not only with outstanding products of the highest quality, but also with their readiness to listen to and understand our needs,” added Bojan Blagonic, project leader, Uljanik.

When delivered, the 211m long ships will operate on routes in the North Sea. They will have 5,500 metres of lane space for vehicles. The orders with Wärtsilä were booked in December 2016 and February 2017, and equipment is scheduled for delivery to the yard commencing in December. CLdN Ro-Ro has an option for an additional two vessels.
