quantified comparisons between different technologies, all through the life cycle of the ship. Based on SimaPro software, this tool gathers the materials and processes specific to the civil and military naval sector, used in the construction phase and during the use of the vessel.


5.3 ECOSHIP (DCNS) In its sustainable


development project, DCNS has


developed an environmental policy to control and reduce the environmental impact of its activities and products. The Ecoship [8] project demonstrates that it is possible to design a military ship with the overall environmental impact throughout its life cycle reduced by 50 % using existing technologies and with an additional cost amortized over 5 years without changing its operational performance. To achieve this, STX has chosen to build the hull in aluminum (lighter), multihull, with straighter stems and a silicone-based antifouling for optimal hydrodynamics.


To reduce power consumption, the engineers have taken the technique of double-flow ventilation which reduces energy costs.


To optimize the performance, Ecoship has a hybrid thermal-electric propulsion system with the possibility of installing a kite for a fuel economy of 6 to 7 %.


Through this project, DCNS has shown that very


significant progress can be made now and that the sharp reduction in consumption can lead to increased autonomy and performance.


5.4 SOLAR ODYSSEY


Solar Odyssey is a solar electric trimaran which aims to circumnavigate the world on solar energy and thus to demonstrate the power of renewable energy. To realize this


prototype, elements from two very ambitious


programs have been applied, one technological and the other from sports.


As a matter of fact, the floats are from the first version of the hydrofoil and the central hull is from an experiment on Alain Gautier's 60-foot trimaran .


Solar Odyssey uses the electricity produced from about 110 m² of solar cells in mono-crystalline doped silicon, encapsulated in composite panels.

6. ECONAV: WITNESS OF THE PROGRESS OF GREEN NAVIGATION.


More and more marine players are interested in green navigation. Whether through research programme or already on the market, projects along the lines of sustainable navigation multiply. It is now necessary to


©2012: The Royal Institution of Naval Architects 3.


To do this, with the support of a working group, EcoNav created a green navigation specification based on socio- economic and environmental techniques and developed an initial assessment grid for equipped vessels based on the principle of life cycle analysis. This certification system


will allow manufacturers engaged in


environmental approach to see their efforts rewarded and so stand out from their competitors. For boaters this will include environmental certification, greater clarity on their purchases and benefits in services or prices from the various ports and insurance partners.


The completion of this certification system is planned for late 2012.
