Propulsion Annual Most Powerful Common- Rail Engine Passes Test The first 12-cylinder Sulzer RT- flex96C low-speed marine engine devel- oped by Wartsila Corporation has suc- cessfully completed its official shop test. With a maximum continuous power out- put of 68,640 kW (93,360 bhp) at 102 rpm, it is reported to be the most power- ful engine so far to employ common-rail technology. The engine is one of four ordered in 2003 for the propulsion of four 7,700 TEU Post-Panamax container liners contracted by Blue Star Reederei, a subsidiary of P&O Nedlloyd BV, with the Japanese shipbuilding group IHI Marine United Inc. After the initial adjustments and run- ning-in, the engine has been subjected to an extensive series of tests. Optimization of the Sulzer RT-fiex sys- tem with this size of engine was com- pleted with an eight-cylinder Sulzer RT- flex96C during March/April at another licensee HSD Engine Co. Ltd. in Korea. Further tests, however, have been made Circle 310 on Reader Service Card Never use anything but GENUINE Harbormaster Parts!

The improved quality of combustion achieved in RT-flex engines which allows such low, stable speeds, together with smokeless operation across the speed range, has proved in service to leave RT-fiex engines very clean with consequent benefits for maintenance. To date, confirmed orders have been placed for a total of 110 RT-flex engines aggregating 4,633 MW (6.30 million bhp). In addition to the 64 Sulzer RT- flex96C engines, the engines in service and on order include seven Sulzer RT- flex84T-D engines for VLCCs, two Sulzer RT-flex68T-B engines for Aframax tankers, 17 Sulzer RT-tlex60C engines and 15 Sulzer RT-flex58T-B engines for various ship types, and five Sulzer RT-flex50 engines for bulk carri- ers. The Sulzer RT-flex96C is adapted from the well-established Sulzer RTA96C engine, the most powerful Sulzer low-speed marine engine type. This is a popular prime mover for the world's largest types of container liners. There are 226 Sulzer RTA96C and RT- flex96C engines in service or on order with an aggregate power output of 13,130 MW (17.86 million bhp).
