MAN 28/33D STC Engine Adds Thai Reference
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.
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.”
28/33D STC range
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).
