The MORE project will focus on harmonizing small- and large-scale multi-degradation rigs, to create a fast track for validation of materials, starting from, but not limited to, metallic materials and metal coatings typically suffering tribocorrosion and multi-degradation (passive metals), to enable the industrial uptake of these methods and improve the systems’ reliability and lifetime. MORE will demonstrate a multi-degradation validation pathway for materials and subcomponents to be used as a case study in the offshore renewable energy sector. While innovative offshore renewable energy device technologies are gaining popularity, operating them in harsh marine environment is a complex and challenging process that jeopardizes the deployment of these very important technologies for the future generations.
