First Wärtsilä Sulzer RT-flex50 engines ordered by Greek shipowner

Wärtsilä Corporation, Press release 5 April 2004 at 12:00 UTC+2

Wärtsilä has sold its first low-speed Sulzer RT-flex50 engines to the Greek shipowner Enterprises Shipping & Trading. The four engines ordered will be installed in four bulk carriers being built at the Fujian Mawei Shipbuilding Ltd shipyard in China. The engines will be manufactured under licence by Diesel United Ltd of Aioi. The vessels are scheduled for delivery in 2006 and 2007.

The Sulzer RT-flex50, developed by Wärtsilä, is based on the Sulzer RTA50 engine, the product of a joint development project between Wärtsilä and Mitsubishi Heavy Industries Ltd. The Sulzer RT-flex50 engine incorporates an electronically controlled common rail system for fuel injection which gives flexibility in engine operation, lower emission levels, and lower fuel consumption at low operating loads compared with conventional low-speed engines. An especially important feature of the engine for Enterprises Group is its smokeless operation.
