Wärtsilä has announced the successful testing of a special version of its RT-flex50 two-stroke slow speed series. Designated the D version, it has the turbocharger relocated on the driving end side of the engine. The new RT-flex50D series is much more compact by locating the turbocharger directly above the fly wheel at the driving end of the engine. In ships with narrow stern sections the engine choice was limited and often required specifying an engine of smaller bore and higher rotational speed. The Wärtsilä RT-flex50D is offered in five to eight cylinders configurations in the power range of 6,100 to 13,960 kW with a speed band of 99 to 124 rpm. Typical applications for the new D series would be in small bulker and product tankers, handymax and panamax bulk carriers, container and feeder container vessels, and feeder ships. [More]
