The aim of this document is to present the activity carried out by the four industrial partners who validated the DTOcean+ suite against five wave energy validation scenarios.

This document collects the main guidelines, standards and procedures applicable to the implementation of the tools and modules in the DTOcean+ suite.

Technology readiness levels are a widely used metric of technology maturity and risk for marine renewable energy devices. To-date, a large number of device concepts have been proposed which have reached the early validation stages of development. Only a handful of mature designs have attained pre-commercial development status following prototype sea trials. In order to navigate through the aptly named “valley of death” towards commercial realisation, it is necessary for new technologies to be de-risked in terms of component durability and reliability. In this paper the scope of the reliability assessment module of the DTOcean design tool is outlined including aspects of tool integration, data provision and how prediction uncertainties are accounted for

This report outlines the proposed architecture and main functions of the DTOcean mooring and foundation design module and its interaction with other elements and modules of the tool

The function and type of mooring and/or foundation system are determined by a number of factors including: cost, site characteristics, expected environmental loading and environmental or legislative constraints. The design of the device and its mode of operation will also influence the decision-making process. It is the role of DTOcean to produce a decision-making tool which has the capability to assess a range of technologies for the design and selection of mooring and foundation systems for marine renewable energy device arrays. In this report, criteria are introduced which can be used to appraise technologies and approaches relevant to MRE devices

In response to the issues identified by the sector and the questions raised by citizens concerning the environmental integration of marine renewable energies in France, the COME3T approach aims to provide elements of expertise, synthesis and recommendations based on a national network of experts. 6 experts contributed to this bulletin on dangerous waves and their characteristics: tsunamis, rogue waves and impact waves. The study of worst-case scenarios corresponding to the most unfavourable conditions possible allowed the experts involved to establish that no environmental issues were identified in response to the question: can fixed-foundation offshore wind farms generate dangerous waves?

The use of an ecological niche model has made it possible to characterize on the one hand the effects of climate change on the native species of the Gulf of Lio, such as displacements of favorable habitats or the reduction of the surface of the habitat. favor of native species. On the other hand, the potential displacement of the favorable habitat of some subtropical species in the Gulf of Lion could be expected. They would then become non-indigenous species (NIS)
