The Royal Thai Navy (RTN) has chosen to power its second modified River-class offshore patrol vessel (OPV) with two MAN 16V28/33D sequential turbocharging (STC) diesel engines.

The 90 m vessel, which will be a more heavily armed version of the first OPV, will be constructed by Thailand’s state-owned naval shipbuilder Bangkok Dock with technical guidance from BAE Systems.

According to a statement released by MAN on the project, the 16V28/33D STC engine is fuel-efficient and particularly suited for vessels like the modified River-class OPV, especially at intermediate- and low-load operations. A variant of the engine is in service with the Royal Netherlands Navy’s Holland-class OPVs.

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.” Source
