Baudouin 12M33.2 Severe-Duty V12 Marine Propulsion Engine

Description

Displacing 39.2 liters from a 60-degree V12 block, this powerplant sustains high bollard pull through continuous ocean towing operations. The Baudouin 12M33.2 Marine Propulsion Engine produces 1,300 BHP continuous output at a low 1,800 RPM. The dry engine mass of 8,598 lbs requires heavy overhead gantry rigging during shipyard hull installations.

Monolithic cast iron forms the narrow 60-degree V12 engine crankcase and individual four-valve cylinder heads. Replaceable wet sleeve cast iron liners seat inside deep-skirt cylinder blocks to withstand severe cylinder pressures. The isolated-ground 24V electrical architecture includes a 9.0 kW starter and 90A marine alternator. Dry engine weight measures 8,598 lbs, requiring engine room space measuring 99.4in length, 58.3in width, and 62.8in height mating to an SAE 0 flywheel housing.

Key Features of Baudouin 12M33.2

Ocean tug operators buy Baudouin 12M33.2 engines to secure long maintenance intervals during heavy barge towing contracts. Strategic equipment pricing provides dredge operators and cargo barge fleets with a heavy continuous-duty diesel engine meeting EPA Marine Tier 3 emission standards.

• Large 39.2-liter displacement generates 3,793 ft-lbs continuous torque at 1,800 RPM.
• High-Pressure Common Rail fuel system coordinates with electronic management to reduce soot.
• Twin turbochargers force air through water-cooled intercoolers to maintain high air density.
• Deep 38.3-gallon oil pan extends oil drain intervals during unbroken transatlantic voyages.
• Tubular freshwater heat exchanger isolates marine raw water from internal cylinder jackets.
• Individual cylinder heads allow single-cylinder overhauls without removing adjacent assemblies.
• SAE 0 housing connects to heavy Masson Marine, ZF, or Twin Disc reduction transmissions.

Bollard Pull Dynamometer Load Testing

Dynamometer test cell data confirms 1,300 BHP continuous output at 1,800 RPM with fuel consumption measuring 0.338 lbs per horsepower hour. Crankshaft journal runout checks out at 0.0004in TIR across all induction-hardened journals. Twin turbocharger boost pressure stabilizes at 36 PSI under maximum continuous towing resistance. Closed circuit coolant temperatures remain steady at 178°F under continuous full-load water brake absorption. Engine room sound meters record 97 dB at 3ft distance during maximum torque output of 3,793 ft-lbs.

Vessel Usability Severe Duty Maintenance

Side crankcase inspection openings unbolt with standard shop sockets, allowing fast connecting rod bearing clearances checks between voyages. Do not buy this 8,598 lbs severe-duty engine for shallow-draft planing hulls or weight-sensitive high-speed catamarans.

• Drain and refill the 38.3-gallon oil pan with fresh marine lube oil every 500 hours.
• Replace spin-on common rail fuel filter canisters and check fuel pressure every 250 hours.
• Inspect heat exchanger tube bundles for mineral scale accumulation every 12 months.
