Ro/Ro duo to have Wartsila propellers and shaft generatorsWritten by Nick Blenkey
MAY 25, 2017 — Wärtsilä is to supply controllable pitch propellers and Power Take Off / Power Take Home (PTO/PTH) shaft generator systems for two new Ro/Ro vessels being built by Croatian shipbuilder Uljanik shipyard for Luxembourg based operator, CLdN Ro-Ro SA. There is an option for an additional two vessels. The orders with Wärtsilä were booked in December 2016 and February 2017.
Wärtsilä will supply the vessels with its latest design, WCP G-hub, which is optimized for high power density. The Wärtsilä 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 propellers will be designed using the OPTIDESIGN method. This uses Wärtsilä’s advanced CFD technology to optimize the interaction between the propeller and hull in order to reach the highest possible performance.
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 shipyard and are happy to be working with them on this project,” says 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,” says Mr Bojan Blagonić, Project Leader, Uljanik.
When delivered, the 211 m long ships will operate on routes in the North Sea. They will have 5,500 m of lane space for vehicles.
The Wärtsilä equipment is scheduled for delivery to the shipyard commencing in December 2017.
