Wärtsilä to Power New DE Tanker

Wärtsilä Corporation received a contract to supply main diesel generating sets for a 19,500 dwt product/chemical tanker being built at Shanghai Edward Shipbuilding in the People's Republic of China. Delivery of the ship is scheduled in August 2005. Ordered by Sweden’s Rederi AB Donsötank, the newbuilding is a double-acting tanker (DAT) which is optimized for efficient ice-breaking when going astern and for efficient sailing in open water when going ahead. Propulsion is by a single electrically-driven azimuthing propeller drive.

Wärtsilä's Engines Tested

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. With five to eight cylinders, the Sulzer RT-flex50 low-speed marine diesel engine covers a power range of 5800 to 13,280 kW at 99 to 124 rpm. It is thus ideally suited to the propulsion of bulk carriers in the Handymax to Panamax size range, product tankers and feeder container vessels. The Sulzer RT-flex50 is based on the Sulzer RTA50 engine jointly developed by Wärtsilä and Mitsubishi Heavy Industries Ltd in Japan.
