Baudouin 12M26.3 High-Power V12 Marine Diesel Engine

Description

High-speed passenger vessels rely on the Baudouin 12M26.3 High-Power V12 Marine Diesel Engine for dependable offshore transit. Engineered as a high speed commercial ferry engine, this powerplant is EPA Tier 3 commercial certified for USCG passenger craft and fast crew boats. Yard riggers must support heavy dry weight during installation. Turbocharger intercooler piping leaves minimal overhead sole clearance.

High-strength cast iron cylinder heads and wet sleeve liners give this Baudouin common rail V12 diesel the rigid backbone needed for planing hulls. High-pressure common rail injection meters fuel cleanly, cutting transom soot during rapid throttle acceleration. A 24V isolated ground system protects aluminum hull plates against galvanic attack. Dry bobtail weight lands at 3,215 kg (7,088 lbs) without reverse gear.

Key Features of Baudouin 12M26.3

Requesting a verified Baudouin 12M26.3 repower quote helps naval architects evaluate engine bed centers and down-angle shaft couplings. Electronic helm displays simplify dual-station commercial bridge rigging.

• Square 150 x 150 mm (5.91 x 5.91 in) bore geometry establishes a 31.8 liter common rail diesel architecture.
• Continuous P1 duty provides 1,200 BHP (883 kW) at 1,800 RPM for commercial routes.
• Intermittent P3 and P4 ratings deliver up to 1,650 BHP (1,214 kW) at 2,300 RPM.
• Turbochargers feed water-cooled charge air intercoolers to ensure dense intake air charges.
• Acts as a fast offshore crew boat engine built for rapid oilfield crew transport.
• Standard SAE 0 housing and SAE 18 flywheel connect to a ZF or Twin Disc transmission.
• Individual four-valve cylinder heads and wet sleeve liners simplify top-end commercial overhauls.

Thermodynamic Efficiency & Fuel Combustion Dynamics

Electronic common rail injection delivers rapid boost pressure as the turbochargers spool past 1,200 RPM, preventing heavy smoke puffs during hole-shot acceleration. Operating this 1600 hp marine diesel at full intermittent sprint consumes approximately 82.4 GPH (312 LPH). Water-cooled intercoolers hold wet exhaust gas temperatures below 1,022°F (550°C) to safeguard internal exhaust components. Ambient engine room temperatures above 122°F (50°C) trigger electronic fueling derates. Provide clean intake airflow. High injection pressures eliminate low-idle slobber across extended harbor holding.

Engine Room Ergonomics & Corrosion Prevention Logistics

Fast ferry engine compartments leave zero room for maintenance errors. Checking engine oil requires 400 mm (15.7 in) clearance above the valve covers. Crankcase breathers demand clean drain lines to keep the bilge free of oily mist. Dual spin-on primary fuel filters need clean drip trays during underway servicing. Sacrificial zinc anodes on cupronickel heat exchanger end caps demand monthly inspection to halt galvanic pitting. Salt crust will seize dry bolts.

• Service cupronickel heat exchanger tube bundles during yearly haul-outs.
• Evacuate the 115-liter oil sump using low-mounted manual drain lines.
• Keep marine gear shaft coupling alignment within 0.05 mm across mounts.
