The Royal Thai Navy has ordered a new 90-m offshore patrol vessel (OPV) to be constructed at Mahidol Adulyadej naval dockyard in Sattahip. 

The newbuilding, an improved River-class design, will be powered by two MAN 16V28/33D STC engines. Locally called OPV No. 2, the order follows that of OPV No. 1, the HTMS Krabi ordered in 2009, a similar vessel that featured two 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.”

With the advent of fuel transition, digitalization, AI and autonomy, innovation in vessel design and operation proceeds at unprecedented speed.
