This deliverable is a review of existing approaches and methodologies for the analysis of ocean energy arrays with a clear focus on the results and conclusions provided by previous experiences. The key outcome is the definition of quantifiable and qualitative metrics for economic viability, reliability and environmental impact which have been adopted in the global set of tools developed within the project DTOcean

The objective of the BENTHOSCOPE project was to diagnose the state and evolution of benthic communities in a rocky marine habitat by listening to the sounds they produce, similar to the stethoscope in the medical field.

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

This deliverable consists of two parts. The first one is a comprehensive review of all the electrical infrastructure technologies between the converter and the point of connection to the onshore electrical grid. The second one is a set of operating regimes of the ocean energy conversion arrays

This report is a comprehensive description of the environmental impacts related to operations and maintenance. All marine operations related to inspection, maintenance and repair lead to environmental impacts due to vessel traffic, noise emissions, handling of mooring lines, anchors and cables, etc.

This report describes the methodology used to define the “validation scenarios”, accounting for the different potential use cases. Given the large number of permutations of tools, use cases, and the set of minimum validation requirements, the number of validation scenarios has been reduced to a number that can be run during the life of the DTOceanPlus project but that are sufficient to fully demonstrate the functionality of the DTOceanPlus suite of tools. The selection process, based on a successive approximation approach, has led to the cases that the potential users in the DTOceanPlus consortium have considered as the most relevant for the sector. In Section 4 of the document, the selected validation scenarios is described; the definition of these scenarios has been completed during the project to ensure that the most updated information is used.

This deliverable consists of two parts, first a legal guide to environmental assessment for floating wind farm projects, then in a second part, a study on the legal framework for the spatial planning of floating wind farms: The place of environmental assessment

Deliverable D4.2 “Stage Gate Tools – alpha version” of the DTOceanPlus project includes the details of the Stage Gate Design Tool, and it represents the result of the work developed during task T4.2 of the project. This tool is an application of a stage gate process which is used in research and industry to provide structure to the technology development process. This approach supports the R&D pathway towards producing reliable and cost-effective ocean energy sub-systems, devices and arrays.

The present document summarises both the functionalities, supporting theory, as well as the more technical aspects of the code implemented for this module. This module will provide the user with a set of metrics and assessments, such as the levelized cost of energy and internal rate of return, relevant to the techno-economic and financial assessments of wave and tidal renewable energy projects at different stages of development. A set of complementary metrics have been included, representing the costs of the systems against a set of benchmark values.
