DCNS in 2015
BARRACUDA, THE ESSENCE OF INDUSTRIAL EXCELLENCE
Powerful, fast and stealthy, the Barracuda features all the latest DCNS group technologies
To produce this kind of submarine, DCNS has brought together the talents of many staff members at four main sites: Cherbourg, Nantes-Indret, AngoulêmeRuelle and Toulon. These sites are working in close collaboration with several hundred subcontracting SMEs, as well as Areva TA, prime contractor for the on-board nuclear boiler. Altogether, a Barracuda involves assembling one million parts and represents 12 million working hours. A challenge made all the more complex in that DCNS is engaged simultaneously in the contruction of four such vessels. The Suffren, first in the series, is in the final stages of integration at Cherbourg, followed by the Duguay-Trouin, Tourville and De Grasse, the first elements of which are currently being produced. Between now and 2029, six Barracuda will have been delivered to the French Navy.
To coordinate and synchronise this major multisite project, DCNS maintains close contact with the teams, in particular via regular monthly meetings involving all programme component managers. At each site, engineers, technicians and managers, organised around collaborative platforms, build lean manufacturing systems together to maintain ongoing procedural improvement. This covers eliminating waste, just-in-time management and real-time status display of work in progress. Driven by this collective energy, the Suffren reached several important milestones in 2015. All the major modules – the navigation operation command post cradle, engine module, armament handling module and auxiliary cradles – have now been completed, tested and incorporated into the hull sections. At Cherbourg, the teams will then bring together and seal the two final sections which, once assembled with the other sections by the summer of 2016, will give the submarine its definitive form. This decisive operation calls for the Group’s most experienced welders. Before carrying out these operations, those concerned are immersed in a virtual reality cube where they can visualise and practice the various operations. “Made in DCNS” quality leaves nothing to chance.
VIA THE BARRACUDA, DCNS engineers make future technological breakthroughs become reality.
