Baudouin marine engines behind engine-room enquiries
Moteurs Baudouin began in Marseille in 1918, moved to Cassis in 2008 and has belonged to the Chinese engine maker Weichai Power since 2009. Its marine diesels work on fishing vessels, tugs, workboats and ferries, both on the propeller and in generating sets. The codes read in a fixed order: the cylinder count first, then the series, then the generation after a point, so the same series can appear in several generations on the same quay.
M26.2 · M26.3
A Baudouin commercial engine built in six, eight and twelve cylinders. The M26.3 is the later common-rail generation, so injection items for an M26.2 and an M26.3 are never assumed to match. Engines such as the 6M26.3 and the 12M26.3 serve as propulsion engines and generator engines, and the use goes into the enquiry.
6M33.2 · 6M33.3 · 12M33.2 · 16M33.3
The larger commercial series, in generations .2 and .3 and in six, twelve and sixteen cylinders, used on tugs and pushboats among others. Cylinder heads, liners, pistons, bearings and injection parts are matched to the complete code and serial.
12M55
The largest Baudouin commercial engine, built for sea-going tugs, deep-sea trawlers, dredgers and ferries. Enquiries are quoted line by line against the code, the serial and the parts catalogue the ship holds.
6F21
The first engine of the F series, introduced after the M33. Filters, cooler elements and gasket sets are quoted against its code and serial like the larger engines.
DP · DNP
Earlier Baudouin series still met on older fishing vessels. The type is copied from the plate exactly, and photographs of the plate, the engine and the removed part are the next evidence when a plate has worn.
Baudouin engine components that reach an RFQ
The list follows a marine diesel from the combustion space to the cooling side and the add-on units. Each line can carry the part number from the parts catalogue or from an earlier order next to the description.
- Cylinder heads, inlet and exhaust valves, valve seats and guides
- Cylinder liners, liner seal rings, pistons and piston rings
- Connecting rod and main bearings and thrust washers
- Injectors, injection pump parts and high-pressure pipes; common-rail items on the .3 engines
- Fuel, lube oil and air filter elements
- Sea water and fresh water pump parts and impellers
- Heat exchanger and charge-air cooler elements, anodes and gaskets
- Turbocharger gasket sets and turbocharger units, quoted from the turbocharger plate
- Thermostats, hoses and drive belts
- Top overhaul and complete engine gasket sets, O-rings and seal kits
What to read off a Baudouin engine before ordering
Two things are read from the engine plate first: the full engine code and the serial number. A square-on photograph of the plate settles most of the points below; the rest come from the ship's own records.
- Full engine code exactly as printed, for example 6M26.3 or 12M33.2, with the figure after the point
- Engine serial number from the same plate
- Use on board: propulsion engine or generator engine with its own alternator plate
- Part numbers from the parts catalogue, an earlier invoice or the old part itself
- Gearbox make and type for a propulsion engine, ordered separately
- For an older DP or DNP engine: photographs of the plate, the engine and the removed part
Supply route review for Baudouin marine engines
Baudouin series have run through several generations under the same name, so two engines of one series are not assumed to share parts. The code and serial are settled first, and the supply route is then chosen line by line.
The generation decides
An M26.2 and an M26.3 share a series name but not their injection system. Part numbers are checked against the full code with its generation and against the serial, not against the series name alone.
Propulsion and generator engines apart
The same series is built for the propeller and for generating sets, set up for different duty. The alternator of a generating set is a separate line, quoted from its own plate.
Original reference or accepted equivalent
Parts a surveyor will inspect are quoted on the original reference. Filters, gaskets, anodes and impellers that carry their own makers' markings can also go on an equivalent-source path for the ship's own spares, within the buyer's list of accepted sources.
Older engines without a clear plate
For a DP or DNP engine whose plate has worn, photographs of the engine, the removed part and any cast or stamped numbers are matched against earlier order lines. If an item was revised after the engine was built, the reply says so and the ship decides.
Baudouin marine engine parts — questions from the engine room
What does the figure after the point in a Baudouin code mean?
It marks the generation of the series. A 6M26.2 and a 6M26.3 are both six-cylinder M26 engines, but the .3 is the later common-rail generation, so many parts differ. Copy the whole code from the plate.
Which data from the plate is needed for a Baudouin engine parts enquiry?
The full engine code, such as 6M26.3 or 12M33.2, and the serial number. Add whether the engine drives the propeller or a generator and any part numbers from the parts catalogue or earlier orders.
Can Vessel Core quote parts for an older DP or DNP engine?
Often, yes. Photographs of the plate, the whole engine and the removed part, plus an earlier invoice for the same engine if the ship has one, are usually enough to start. Each line is confirmed before it is quoted.
Does Vessel Core overhaul Baudouin engines?
No. Vessel Core identifies and supplies spare parts only. The work on board or in the yard stays with the crew or the workshop the owner chooses; the enquiry lists the parts that work needs.
Is Vessel Core connected to Baudouin?
No, and there is no agreement of any kind. Vessel Core holds no distribution, representation or partnership agreement with Baudouin, and quoting a component against one of its designations implies no approval by the maker and no claim of interchangeability.
Send the engine plate and the list of items.
Give the full engine code, the serial number, the items needed and the port. Engine parts, generator items and gearbox lines are quoted separately, so the ship can decide what to renew now and what to keep as a spare.
