Wärtsilä and Diesel United Ltd in Japan have signed a ten-year renewal of their co-operation agreement for the sale, manufacturing and servicing of Wärtsilä low speed marine engines.

Continuation of licence agreements has not been affected by the Chinese majority ownership of the Wartsila two-stroke business, as evidenced by the renewal of this important licence. Diesel United has been a Wärtsilä low-speed engine licensee since October 1948; in fact the renewal document was signed on the 66th anniversary of the original agreement. This has been Diesel United's sole licence for low-speed two-stroke diesel engines since then.

The licence grants Diesel United the right to use Wärtsilä's low-speed technology for manufacturing, sale and servicing of engines in the Japanese market and some export countries, also defines and regulates intellectual property rights, and the delivery and feedback of technical information and support. Besides building engines, Diesel United has, over the years, contributed to the development of Wärtsilä low-speed engines and built the first examples of new engine types. Recently Diesel United has been closely involved with two-stroke low-pressure dual-fuel engine technology. This successful co-operation has led to a recent agreement for installation of 6-cylinder Wärtsilä X72DF dual fuel test and demonstration engine at the Diesel United Aioi works, which is scheduled to become operational in the first quarter of 2015.

The first vessel equipped by Diesel United with a Sulzer engine was the 1950-delivered Kyoei Maru powered by a 6TD36 trunk-piston two-stroke engine, and since then more than 2,900 engines have been built under licence, totalling more than 38 million bhp.

"Wärtsilä and Diesel United have a long common history in introducing new technologies to the Japanese and international shipbuilding industry. The extension of our licence co-operation agreement for a period of ten years will enable us to strengthen our presence in the important Japanese shipbuilding market and to make sure that our customers will also in the years to come be able to benefit from the availability of competitive, high quality fuel efficient and environmentally friendly main propulsion engines for large merchant vessels built by Diesel United" said Martin Wernli, vice president, two-stroke, Wärtsilä Ship Power.
