Applying the concepts of Digital Twin and virtual simulations, the CWA describes a set of protocols for modernising, diagnosing, inspecting, repairing, disassembling, upgrading, refurbishing, remanufacturing, recycling and reassembly and testing of Large Industrial Equipment. The CWA will provide a formal Protocols Specifications Document (PSD), specifying for each protocol unambiguously steps, processes, deployment requirements and conditions, etc. The development of a CWA, based on the consensus of the parties, is the most suitable tool to provide policymakers and all interested stakeholders with a guide, a reference document which, although not binding, will act as a catalyst for further documents, proposals and future European projects. This workshop is created under the currently ongoing LEVEL-UP project (Grant Agreement # 869991) which is carried out in the framework of Horizon 2020.
