What Chantier Naval de Marseille does

Chantier Naval de Marseille (CNdM) is a French ship repair, conversion, and refitting yard operating three dry docks (No. 8, No. 9, and No. 10) at the Grand Port Maritime de Marseille under a 172,000 sqm site with 32,800 sqm of covered area. Dry Dock No. 10, operational since 2017, is the largest dry dock in the Mediterranean at 465m x 85m and is one of the few facilities worldwide that can accommodate next-generation mega cruise ships. Founded in April 2010 by sister company San Giorgio del Porto, CNdM is a wholly-owned subsidiary of the Italian Genova Industrie Navali Group (GIN Group).

The yard delivers four core service lines: ship repair and maintenance, specialized services (propulsion work including tail shaft/rudder removal and complete thruster/azipod overhaul), fully customized refitting and conversion, and painting/surface treatment using robotic hydro-blasting at up to 3,000 bar. CNdM holds GTT certification for LNG membrane repairs (membrane tank testing, cryogenic piping, valve/pump overhauls), ISO 9001:2015 and ISO 14001:2015 certifications, and obtained Green Marine Europe certification in 2024. It is supported by 11,000 sqm of equipped workshops, 20,600 sqm of covered storage/heavy steel fabrication, and 450 linear metres of equipped berths plus Pier 190 (450m x 10.50m depth).

Revenue is generated through project-based, quote-driven professional services contracts with enterprise maritime operators, with no publicly listed pricing. CNdM serves cruise lines (Norwegian Cruise Line, AIDA, Carnival, MSC, Costa, Celebrity, Oceania, TUI, Ritz-Carlton), offshore energy (Saipem), LNG/Floating Storage (OLT Offshore LNG Toscana), commercial vessels, and government/navy clients (US Navy). The go-to-market is enterprise field sales complemented by a network of country-specific commercial agents across Europe, North Africa, and Asia, and active participation in major maritime exhibitions (Euromaritime, EURONAVAL, SMM Hamburg, Gastech, Seatrade Cruise Global). Within the GIN Group, CNdM and SGdP position themselves as a one-stop Mediterranean repair, conversion and refitting pole with combined 8 dry docks and over 2 km of repair quays.
