Wartsila upgrades RT-flex50 engines

Wartsila upgrades RT-flex50 engines

Seoul: Leading engine manufacturer Wartsila has introduced a new, '-D' version of its RT-flex50 low-speed marine engine. The newer version boasts a 5.1% increase in power rating to 1745 kW/cylinder at the same running speed of 124 rpm and lower brake specific fuel consumptions (BSFC) when compared with the existing '-B' version.

In a statement, the company said, "For a typical bulk carrier with a six-cylinder RT-flex50 engine this can translate into annual savings of $76,000 when operating for 6000 running hours a year with heavy fuel oil costing $300 per tonne. Even greater savings are possible if the engine is derated to a lower running speed (rpm) to gain the benefits of a better propulsion efficiency."

The RT-flex50 engines are aimed at the propulsion of a variety  of ship types - including bulk carriers from handymax to panamax  sizes, product tankers, multipurpose cargo carriers and feeder container  vessels.  [03/10/07]
