| Résumé : |
Unlike many industrial strucures, ships often contain a variety of multi-layer coating systems on a single vessel, and even on the exterior hull itself, often including a complex sequence of anticorrosive layers followed by antifouling layers. This article focuses on the recoating of ship's exterior hull that resulted in catastrophic failure before the ship was ever returned to service. |
