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. In this bulletin, 6 experts contributed to defining the different phenomena that could facilitate the spread of non-indigenous species following the development of offshore wind farms. Several recommendations have been issued to limit the impact on marine ecosystems of the relay effect, ballast water release and the storage of offshore infrastructure in ports.

The objective of Task 4.3 was to carry out the testing of the Stage Gate design tool in order to verify that it meets all the previously defined requirements (in WP2 and T4.1). This report documents the outcome of T4.3 “Verification of the Stage Gate design tool.”

Spatial study and sensitivity of network indices to wind farm closure and climate disruption using an Ecospace model

This document is the third annual report on dissemination and communication activities regarding DTOceanPlus project.

This paper presents a first framework for OSPAR Regional Sea Convention food web indicators based on ENA. These are presented here focusing on their applicability and what is needed for implementation, illustrating their potential use by case studies.

The objective of the DTOceanPlus project was to develop a software suite of open source advanced tools for the selection, development and deployment of ocean energy systems. DTOceanPlus project made it to develop and demonstrate an open source sotftware suite of second generation design tools for ocean energy technologies including sub-systems, energy capture devices and arrays. These tools support the entire technology innovation process, from concept, through development, to deployment. More broadly, the project also provided an industry standard for communicating technology descriptions throughout the sector. To complement the numerical work, an extensive market analysis of the ocean energy sector is publicly available.

The objectives of the AESTUS project were: • To develop and finalise the tools and procedures necessary to create relevant databases. • To analyse these databases to acquire new knowledge on turbulent phenomena within high intensity flows that can be used by engineering companies for their design studies.

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?
