The life cycle assessment took into account a submarine’s life from cradle to grave (shipbuilding in a yard, active duty, shipbreaking after withdrawal from active duty). The analysis quantified the environmental impact on three families (damage on human health, damage on ecosystems, natural resources depletion). That first analysis revealed the systems to be improved, from propulsion system to limit diesel-oil consumption and the exhausts of SOx and NOx to be reduced, the electrical energy storage to increase the capacity, and lower the indiscretion ratio, the onboard systems to reduce the electrical consumption, the treatment of sewage and bilge waters, as well as solid waste, the acute choice of materials to be less impacting on the environment. Based on this analysis, the design team challenged new architectures and technologies with high technological readiness levels. It means the study was lead with technologies existing at the stage at least of prototype, to guarantee the realistic approach and avoid science-fiction. Based on these issues, DCNS engineers, as testified by its ISO14001, have identified some interesting mature solutions, fitted for future submarines or potential retrofits, have gained knowledge to perform an integrated environment friendly approach in the design for submarines, confirmed that design with high environmental constraints resulted in more efficient submarines on the operational point of view.enCopyright status unknownConference paper2021-10-18591634Fusil, E.
