First order for Wärtsilä RT-flex35 engines comes from China

The Wärtsilä licensee, Yichang Marine Diesel Engine Co. (YMD), manufacturing low-speed marine engines in China, has signed a contract with Ningbo Donghai Shipping Co. Ltd to deliver five 6-cylinder Wärtsilä RT-flex35 common rail diesel engines with a power output of 5,220kW for a series of five chemical tankers. Delivery of the first engine is scheduled for August 2011.

“Among low-speed engines with smaller bores, the biggest advantages of Wärtsilä RT-flex35 are its low fuel consumption and its compliance with environmental regulations, both of which fully meet our customer’s expectations. Operational flexibility and the improved fuel efficiency offered by the RT-flex35 engine were important considerations when YMD decided to offer this engine type,” says Andrew Stump, sales director, two-stroke engines, Wärtsilä in China. “Wärtsilä will continue to provide support during the project implementation process to ensure the highest levels of quality and on-time delivery,” Stump continues.

The 17,000 dwt chemical tankers will be built by the Ningbo Shipyard Group in the province of Fujian, China. The ship owner is Ningbo Donghai Shipping Co. who will operate the ships in international trade between the Far East, the Middle East and Europe.

Wärtsilä started the product development project for Wärtsilä RT-flex35 engines three years ago as a cooperation project with Mitsubishi Heavy Industries Ltd in Japan and YMD in China. The new engine is designed to provide optimal power and speed combinations for a number of ship types, including handy size bulk carriers, product tankers, general cargo ships, reefer ships, feeder container ships and small LPG carriers. The engine is available in five to eight cylinder configurations and covers a power range of 3,475-6,960kW at 142-167 rpm.
