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.”
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
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).
