Brest (France - EU) - 16/12/2010 - 3B Tips - Paintings silicone were applied on the fairing of the frigates' Aconite 'and' Surcouf . These things prevent dirt from attaching to the hull and allow a gain of fuel consumption.
early March, the frigate Aconite came into periodic unavailability for maintenance and repair (IPER) for three months. This technique led off by DCNS falls within the normal life cycle of the building. At the request of the Navy, the Aconite has indeed become the first French naval vessel to benefit " a cleaning by ultra-high pressure associated with an application of silicone protector .
A painting of the Japanese Nippon Paint to silicone "antifouling" that prevents dirt was placed on the hull of the vessel, improves water slides on the ship and decreasing fuel consumption.
This painting allows simplified maintenance of the hull. The service fleet support of Navy, initiated this project will have five years to verify that this painting "Green" is well adapted to the gray ships as vessels for civilians who are already using it. A second frigate Surcouf (second building Class Lafayette, who have been to concede the title of "stealth frigates " share the emphasis on reducing their radar signature and acoustic) also benefited from this painting.
If both tests are successful, the Navy could generalize its use to all of its ships after a follow-up of two buildings and resistance analysis of paintings.
This type of silicone paint was used for the first time, by yards STX Saint Nazaire to the hull of the cruise ship MSC Poesia in 2008. Although complex to ask, because this material requires specific weather conditions, the environmental aspect was not the only convincing argument to MSC to adopt this painting very expensive (50 euros per liter). An important point was also reduced from March to February fairings per decade and the immobilization time to repaint the hull.
Since 2008, all antifouling paints containing organotin compounds are banned by the International Maritime Organization (IMO). Instead of organotin compounds, paints now contain compounds organometallics such as zinc and copper oxide according to the REACH directive. This painting is part of the eco-design tool (see Section 16.3.2010) CONVENAV * set point in DCNS with the participation des Arts et Metiers ParisTech, SITA, Ifremer and Veritas.
Tomorrow Friday, we'll give more details on Marine Biodiversity Day on Dec. 15 held in Brest, the capital of biodiversity by DCNS and the Navy.
