Corporate profile

Expertise, reliability and Maxi Dry-Docks.

CNdM was founded in April 2010 by San Giorgio del Porto to operate dry-docks No. 8 and 9 of GPMM - Grand Port Maritime de Marseille (Marseille Port Authority) and from 2016 dry-dock No. 10, the biggest graving dock in the Mediterranean sea. Despite its relatively young age, the yard draws on a long and venerable legacy.

Indeed, with over 175 years of services and craftsmanship, Marseille has positioned itself as an expert venue for ship repair, maintenance and conversion. Over the past century, the architecture of companies and facilities has changed considerably as the environment adjusts to the market. CNdM, employs 110 people including naval architects and mechanical engineers, skilled workers and specialized technicians.

The yard, alongside its sister company SGdP - San Giorgio del Porto - operates eight dry-docks and over 2 km of equipped repair quays, is capable of handling the largest vessels and is perfectly positioned to support the needs of the

maritime, offshore and renewable energy sectors, providing specialized service and assistance 24/7/365.

The yard is located in the eastern section of the Port of Marseille, the largest in France, in the center of a large traffic zone extending from Genoa to Barcelona. The harbor benefits from direct access to the western Mediterranean Sea with no tideor lock restrictions, which means vessels up to 11.70m can enter CNdM docks with no time constraints.

The area enjoys a favorable climate for ship repair activities, with an average of less than 60 days of rain per year. Directly connected to highway, the yard is close to the downtown area (6 km from the Marseille Saint-Charles Central Railway Station), and to the airport of Marseille Provence (20 km). International connections are easy, saving owners and operators time and money.
