The Royal Thai Navy will build a new offshore patrol vessel (OPV) that will be powered by 2 × MAN 16V28/33D STC engines. The 90-m newbuilding will be constructed at Mahidol Adulyadej naval dockyard in Sattahip. The vessel is an improved River-class design.
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.
The range offers 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 and proven in service. It features:
a high power-to-weight ratio
best-in-class SFOC
low maintenance costs due to long service intervals and on-board maintenance
a robust design for high availability
continuous low-load operation capability
high torque for fast acceleration
compliance with IMO Tier II and EPA Tier 2 (Tier III with SCR).
