The first 12-cylinder Sulzer RT-flex96C low-speed marine engine developed by Wärtsilä Corporation has reportedly successfully completed its official shop test. With a maximum continuous power output of 68,640 kW (93,360 bhp) at 102 rpm, it is the most powerful engine so far to employ common-rail technology. The engine is one of four ordered in 2003 for the propulsion of four 7700 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.
