Marine renewable energy systems involve single or arrays of devices that are secured to the seafloor via foundations and/or anchors. These MRE devices will transmit long-term cyclic loads to the seafloor sediment or rock, which may affect seafloor material properties and hence the overall physical performance of the MRE system. The response of seafloor sediments or rock formations is uncertain for the novel MRE systems and especially large arrays of 10s to >1000s of devices. This report summarizes critical inputs and tools for the design and analysis of foundations, anchors, and the response of the seafloor materials

This report consists of a comprehensive description of the logistic functions and associated logistical model forming the installation module developed within the frame of the global DTOcean tool. The overriding goal is to disclose the structure and content of the installation module

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

The objective of the CARAVELE project was to improve the characterisation of extreme winds by combining atmospheric models with satellite and in-situ observations.

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

The objective of the ABIOP project was to develop biofouling characterisation and quantification methods to make the design and maintenance of ORE systems more reliable. ABIOP has identified the research needs that will enable better identification and management of the risks relating to the ORE components most sensitive to biofouling. Initial in situ measurements were also carried out to characterise biocolonisation in the Atlantic and Mediterranean from an engineering and environmental point of view. The necessary additional studies are being carried out within the framework of the ABIOP+ project.

Measurement of the diameter of the biocolonised moorings and the composition of the biofouling at T+12 months of immersion.

Database of images collected at ABIOP monitoring sites (UTLN = Mola buoy offshore Banyuls, SEMREV = special marks east and north, UN = biocolmar buoy) + report on biofouling characterisation (rapport_taxo_ABIOP_provisoire)

The main objective of this atlas is to summarise the knowledge acquired on biofouling, and more generally on communities of living organisms on hard substrates, available today in mainland France and the French overseas territories, in order to anticipate the issues that this phenomenon will pose in an ORE context. The atlas is based on the most exhaustive bibliographical analysis possible, including A-level scientific articles, reports (training courses, monitoring, studies), and works presenting the results of studies conducted in French waters
