Wärtsilä has been contracted to provide its controllable pitch propellers and Power Take Off / Power Take Home (PTO / PTH) shaft generator systems for two new RoRo vessels, which are set to be owned by Luxembourg-based operator CLdN Ro-Ro.
The vessels are currently being built at Uljanik shipyard in Croatia, under a deal that includes an option for two additional vessels.
Wärtsilä will provide its new WCP G-hub design, which has been optimised for high power density, as part of the new commitment.
The agreement also includes Wärtsilä’s propeller shaft line system that features propulsion controls, as well as a stern tube package with seals and bearings, intermediate shaft line bearings, and various accessories.
The propellers will be designed via the OPTIDESIGN method, which uses Wärtsilä’s advanced CFD technology to optimise the interaction between the propeller and hull in order to achieve the highest possible performance.
Wärtsilä’s shaft generator system is capable of powering the main engine, and can function as a motor in the event of the main engine becoming inoperable.
Delivery of the equipment is scheduled to be completed by December.
Wärtsilä marine solutions power conversion director Peter Rogers said: “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.”
The 211m-long CLdN Ro-Ro vessels will be deployed on routes in the North Sea upon delivery, and will be specially designed to contain 5500m of lane space for vehicle storage.
