Chantiers de l'Atlantique, based in Saint-Nazaire, France, is a globally renowned shipyard with a rich history in shipbuilding. Specializing in the design, construction, integration, testing, and turnkey delivery of highly complex ships and maritime structures, the company is a key player in cruise ship construction (some of the world's largest), naval vessels (aircraft carriers, LHDs), and increasingly, offshore renewable energy solutions like electrical offshore substations and foundations for wind turbines. They are known for their innovation, engineering excellence, and capacity to deliver large-scale, technologically advanced projects.
The Saint-Nazaire site serves as the primary hub for all shipbuilding activities, including design, engineering, pre-fabrication, assembly, outfitting, sea trials, and corporate management. It also houses significant R&D facilities.
One of Europe's largest shipyards, featuring extensive dry docks (including the Joubert Lock, one of the world's largest), massive gantry cranes (e.g., 1,400-tonne crane), advanced panel lines, block assembly halls, and a dedicated logistics platform.
The work culture is characterized by a strong engineering focus, project-based teamwork, high safety standards, and a commitment to innovation and quality. It's a demanding environment due to the scale and complexity of projects, fostering collaboration among diverse technical specializations.
The Saint-Nazaire shipyard is historically significant for France's maritime and industrial heritage, a major employer in the region, and a critical asset for European shipbuilding, particularly for large cruise ships and complex naval platforms.
While its primary shipbuilding and manufacturing operations are centralized in Saint-Nazaire and Montoir-de-Bretagne, Chantiers de l'Atlantique maintains a global presence through its delivered vessels operating worldwide. The company supports these assets through international after-sales services, maintenance, repair, and modernization programs. Its sales and project teams engage with clients globally, and its supply chain is international. The offshore energy division also installs structures in various international waters.
