Locally called OPV No. 2, the order follows that of OPV No. 1, the ‘HTMS Krabi’ that was ordered in 2009, a similar vessel that featured 2 × 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.”
