Chantiers de l’Atlantique and NOV-BLM have combined their skills in the design of naval vessels and complex lifting systems to jointly develop, for over 5 years, systems for launching and recovering drones in severe environmental conditions. The first system was tested in real conditions up to sea 5 in the spring of 2022.
Chantiers de l’Atlantique is a shipyard unique in Europe for its ability to design and build custom vessels up to 400m long. Its engineering is co-located on the same site.
Founded in 1841, NOV-BLM is today the French subsidiary of the multinational NOV, a world leader in marine and offshore equipment.
‘Chantiers de l’Atlantique: designs and builds recent large ships for the French Navy (PHA, BRF…) and cruise ships for the world’s leading shipowners (MSC, RCCL,…). It also integrates innovative equipment for its customers (RAM system for BRF, Magic Carpet, etc.).

Chantiers de l’Atlantique is recognized for its expertise in building large, high-value-added vessels, particularly cruise ships and large military vessels.
Seeking to move beyond marine fuel oil, the shipyard has developed extensive experience in LNG-powered vessels and is also turning to hydrogen as a carbon-free energy source.
SolidSail, developed by Chantiers de l’Atlantique, is a sail propulsion solution featuring a slender, rigid wing.
The massive 1,050 m² rigid test sail rotates 360 degrees on its axis and tilts 70 degrees to pass under bridges.
It has a total height of approximately 73 meters and consists of 10 panels (eight large and two small) that fold onto one another. These panels are made of composite materials: fiberglass/epoxy for the membrane and carbon/epoxy for the frame.
In addition to this mainsail, a 450 m² jib is currently under development.
Les Chantiers de l’Atlantique sont reconnus pour leur expérience dans la construction de grands navires à haute valeur ajoutée, en particulier les navires de croisière et les grands bâtiments militaires

The new LNG-powered MSC World Europa will be equipped with a 150-kW SOFC fuel cell prototype.
The fifth ship in the Edge series for Celebrity Cruises will be powered by methanol, with two of its five engines being tri-fuel, capable of running on MGO (marine gas oil), HFO (heavy fuel oil), and methanol.
Three 1,500 m² SolidSails will be installed on the Orient Express Silenseas, a 220-meter cruise ship.
Two 1,100 m² SolidSails will be installed on the NEOLINE cargo ship.
As part of the retrofit of the “Pont-Aven” ferry operated by Brittany Ferries, the company turned to the engineering offices at Chantiers de l’Atlantique to digitally simulate various bow bulb shapes, but without conclusive results. They therefore jointly turned their attention to modifying the stern and observed much more promising results. Ultimately, the ship’s hull was redesigned to reduce fuel consumption. It was extended by approximately 3 meters at the stern to reduce hydrodynamic drag.
