Posted on August 26, 2005

The first two of the latest Sulzer RT-flex50 common-rail marine engine type developed by Wärtsilä Corporation, have successfully completed official shop tests and class type approval tests at Wärtsilä's licensee Diesel United Ltd in Japan. Two six-cylinder engines were involved in the tests at Diesel United's works in Aioi, Japan, each with a contracted maximum continuous power of 9720 kW at 124 r/min.

The first engine completed its official shop tests in July and the second engine completed its official shop test in August. In the presence of representatives from the principal classification societies, it also successfully passed the type approval tests for Sulzer RT-flex50 engines and for the WECS-9520 electronic control system that is now incorporated in Sulzer RT-flex engines.

The first 6-cylinder Sulzer RT-flex50 engine is for export to Korea for a 37 000 tdw product tanker under construction at Hyundai Mipo Dockyard Co Ltd. The second 6-cylinder RT-flex50 engine will be delivered to Shanghai Edward Shipbuilding Co Ltd in the People's Republic of China for installation in a 19 625 tdw cargo vessel.
