The structural integrity of vessels is a vital aspect of international importance for the risk it implies, if it is compromised. In this regard it should be noted that one of the major contributing factor of incidents at sea is the inability of marine structures to withstand corrosion phenomena caused by the marine environment, in combination with mechanical fatigue phenomena.
An innovative technology, widely used in the aeronautical sector for repair and reinforce aluminium structures, has been studied. Thus, the technology transfer has been accomplished by studying the effectiveness of patching damaged steel structures with prefabricated composites. Special emphasis was placed on the dissimilar composite- steel adhesive joint strength and performance over time. PARCHE project aims at fully developed this new solution for marine applications. Thus a broad range of composite laminates, surface treatments and adhesives had to be study so to maximize the strength of the solution under the different load scenarios possible. The performance of the solution was validated against long- term durability tests, and the system was monitored in order to check its structural integrity. Finally, the optimum combination was scaled-up by finite element analysis (FEM), and validated on large scale demonstrators in which several artificial defects were performed.
