To facilitate the development of the wave energy converter (WEC) industry, a considerable effort needs to be conducted to establish appropriate international guidelines that can reduce uncertainties, standardise e.g. design or manufacturing approaches, and streamline the accreditation process up to commercial arrays. The marine energy industry is still at its infancy, and no dedicated standards have been developed to date. Recently, a number of high-level documents that have approached WEC

Moreover, more mature industries such as the maritime, oil and gas and offshore wind sectors present similarities to some aspects of the marine renewable energy sector, in aspects such as e.g. design of marine structures. A range of key documentation from such industries has therefore been used to date to support the development of WEC devices. As part of the MegaRoller project, one of the key objectives is to monitor the development of technical specifications, guidelines and standards relevant to the WEC industry, and in particular to the MegaRoller technology. Such monitoring aims to guide the design, implementation and integration of the Power Take-Off (PTO) and thereby facilitating its commercialisation. In a preliminary step, this report reviews existing standards and their applicability, and documents an analysis related to the existing documentation. The objective is to identify any salient gaps and to ensure the appropriate applicability of relevant design codes during the project. Overall, the review evidenced two essential differences between WECs and other, more mature offshore applications: 1. Being (in general) unmanned structures, the safety factors of WECs associated with a specific failure could potentially be lower than the ones currently recommended in the standards, as the consequence of failure may be considered less critical when compared to equivalent failure in a manned stru [...]
