MAY 27, 2016 —A  90 m offshore patrol vessel (OPV) to be built at Mahidol Adulyadej naval dockyard in Sattahip,Thailand, will be powered by two MAN 16V28/33D STC engines.

The vessel is an improved River-class design and is locally called OPV No. 2, the order follows that of OPV No. 1, the HTMS Krabi, ordered in 2009, a similar vessel that also featured twin 16V28/33D engines.

Olivier Condemine, Senior Sales Manager – Naval & Governmental – MAN Diesel & Turbo said: "Sequential turbocharging improves the already proven performance and fuel-efficiency of the 28/33D engine, especially at intermediate and low-load operations – known as silent running – which is very important for this kind of vessel."

The 28/33D STC range is offered in 12-, 16-, and 20-cylinder configurations covering power requirements from 5,000 up to 10,000 kW per unit. The 28/33D STC engine is the most powerful engine in its class.
