Wärtsilä Corporation has received the second order for Sulzer RT-flex diesel engines. These apply common-rail fuel injection with full electronic control to Sulzer RTA-series low-speed marine diesel engines for greater flexibility in the way the engines operate to deliver benefits such as lower exhaust emissions, or lower fuel consumption at part load. Two seven-cylinder Sulzer RT-flex60C engines have been ordered to propel two 13,200 tdw container-reefer ships, scheduled for delivery in 2003.
Each 7RT-flex60C engine will have a maximum continuous output of 16,520 kW (22,470 bhp) at 114 rev/min. These engines will be built at Wärtsilä’s Trieste factory in Italy. They are highly-sophisticated 21.3-knot refrigerated cargo ships designated Flexcon 21 that are able to carry various cargoes. The Flexcon 21 design originates from Schiffko in Hamburg.
The first Sulzer RT-flex production engine is currently being erected in the Ulsan works of the Wärtsilä licensee Hyundai Heavy Industries. It is a 6RT-flex58T-B engine for installation in a Handymax bulk carrier due for delivery in July 2001.
