Wärtsilä Corporation has received the second order for Sulzer RT-flex diesel engines, which are powerplants that apply common-rail fuel injection with full electronic control to Sulzer RTA-series low-speed marine diesel engines. The units are reported 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 dwt containerized reefer ships contracted at Estaleiros Navais de Viana do Castelo in Portugal. Each 7RT-flex60C engine will have a maximum continuous output of 16,520 kW (22,470 bhp) at 114 rpm. The engines will be built at Wärtsilä's Trieste, Itlay facility. The ships have been contracted by the Agricultural Export Co.
