It delivers from 882 to 1,215 kW (1200–1,650 hp) depending on the duty class, and is designed specifically for marine use by Moteurs Baudouin, the French manufacturer that has served the marine sector since 1918.
Available ratings by duty class (ISO 3046/1 standard): - P1: 882 kW / 1,200 hp at 1,800 rpm (approx. 207 l/h) - P2: 972 kW / 1,320 hp at 1,800 rpm (approx. 232 l/h) - P2: 1,032 kW / 1,400 hp at 2,100 rpm (approx. 250 l/h) - P2: 1,104 kW / 1,500 hp at 2,200 rpm (approx. 275 l/h) - P3: 1,215 kW / 1,650 hp at 2,300 rpm (approx. 311 l/h)
Key advantages highlighted by the manufacturer: excellent fuel consumption; IMO III / EPA Tier 4 (with SCR) and all major certifications; outstanding performance in heavy-duty applications.
With the Baudouin SCR after-treatment system it meets IMO III and EPA Tier 4. The SCR is compact and modular (1 m³ catalyst that rotates 360°), can be mounted over the engine, over the gearbox or stand-alone, and cuts average fuel consumption by up to 5% and noise by up to 25 dB.
