Shipyard Facilities

The shipyard is located in the core of the port of Marseille, France in the ship repair area.

Chantier Naval de Marseille is located in Marseille eastern harbour with one of the Mediterranean’s largest heavy industrial facilities

CNdM operates large, modern and well-equipped workshops situated in front of the two dry docks, No. 8 and 9. Each of these workshops is involved in a single activity (mechanical work, steelwork, pipe work, lifting, logistics, electrical work and general store), and is properly equipped with significant overhead cranes and advanced machinery.

CNdM operates dry docks No. 8 and 9 in Marseille Port, capable of receiving the largest vessels, and 450 linear meters of completely equipped berths. CNdM has dry dock No. 10 (the largest in the Mediterranean) with a 465x85 mt capacity.

Marseille has many interesting tourist attractions, museums and famous city landmarks. Located on France's Mediterranean coast, is the country's largest port and one of its oldest cities.

The Port is a port-of-call for many Mediterranean cruises and the train station is the departure point for rail service to cities in France. High-speed TGV trains travel between Paris and Marseille in just three hours, the airport, located in Marignane France, is a major airline hub for flights to African and European destinations.

The shipyard’s in-house workshops allow Chantier Naval de Marseille to act as general contractor in all activities.

Mechanical Workshop

In the mechanical workshop the yard has 3,300 sq. meters properly equipped with overhead cranes up to 50 tons and all necessary tools machines such as: lathes (including a 13 mt long sliding bed lathe, a vertical lathe with 3 mt diameter capacity), grinding machines, milling machines, slotting machines, drills, saws, cutting machines, descaling machines, boring machines (including a large horizontal boring machine), press, cleaning station, set pressure station, test station, and an injection bench. The mechanical workshop is perfectly suited to cover the whole range of marine applications, from delicate diesel injection works to heavy gear machining such as rudders, tail shafts, thrusters, and propellers.

Pipe and Steel Workshop

In the steel and pipes workshop, CNdM has 3,300 sq. meters properly equipped with overhead cranes up to 50 tons and all necessary machines to cut, shape, weld and fabricate any steel or pipe you may need. The tools include a plasma cutting set, a guillotine shear, a punch, several chain saws, a nibbler, band saws, press, hand folding machines, bending machines, column drills, lathes and threading machines.


CNdM provides dedicated storage areas, covered and secured, up to 4,000 sq. meters, to stock owners and suppliers of spare parts and equipment; these areas are especially convenient in cases involving conversion and refurbishment of passenger vessels.

Dry Docks and Berths

Advanced facilities capable of handling any kind of vessel

CNdM operates dry docks No. 8 and 9 in Marseille Port, capable of receiving the largest vessels, and 450 linear meters of completely equipped berths. CNdM has dry dock No. 10 (the largest in the Mediterranean) with a 465x85 mt capacity.

The drydocks, directly managed by the shipyard, are covered by cranes up to 50 tons (150 tons at dock No. 10).
The drydocks are run on a 24h/7/365 basis and can be mobilized at short notice.

Forme 10

The dry-dock No.10 is one of the world largest facilities. It can accomodate the new generation of mega ships up to 465 mt.

Graving dock No. 10 of Marseille Port was opened in 1975 to accommodate the new generation of ULCCs and successfully operated for a decade as the largest of its type in the Mediterranean and the third-largest in the world.

The oil crisis, curtailing the movement of giant oil tankers, and emerging competition from Asian ship repair, caused activity to slow down gradually in the 1980s. Since the beginning of the 21st century, the dock has been used only as a floating berth.

Ongoing development of the Mediterranean cruise business, as well as the increasingly larger size of container ships, have given new impetus to this giant drydock. Thus, the Port of Marseille decided to overhaul the facilities and commissioned an operator for this unique infrastructure.

On June 2012, Société d’Exploitation de la Forme 10, a subsidiary company of Chantier Naval de Marseille, signed a long-term concession with the Port of Marseille as the exclusive operator of Forme 10.

Work aimed at revamping the giant dock got under way in mid-2013 with the construction of a new floating concrete gate (with an opening width of 85 mt), overhaul of the pumping system and repair of the lifting facilities (including a 150 tons capacity crane on rails). All networks (seawater, power, sewage, cutting gas…) are being carefully redesigned in order to provide the best possible service to the new type of vessels targeted for accommodation.

Form 10 has been officially inaugurated at the presence of  the President of the Region Provence Alpes et Côte d’Azur and the Mayor of Marseille on 4 December 2017.
