This deliverable is the second report on dissemination and communication activities, i.e. the end of the project review. It presents all of the activities which have taken place within DTOcean project

Project website is one of the main communication and dissemination tools. Web presence is therefore a central element of the DTOcean project and activities

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.

During the ABIOP project launch meeting, the consortium agreed to add a task to the project aimed at identifying the challenges of biocolonisation in an ORE context. This additional work is indeed necessary because it allows the organisation, updating and presentation of the reflections undertaken by biofouling experts from various industrial and research entities and federated by FEM, for several years on this topic.

This document briefly presents the methodology used to build the Ecosim and Ecospace models representing the extended Seine Bay ecosystem as well as the main results.

This paper presents the assessment of potential impacts of changes in species distribution by climate change on the extended Seine Bay ecosystem.

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.

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

The objective of the COME3T project were: • To provide elements of expertise, synthesis and recommendations on the identification of environmental priority issues for the ORE through the establishment of a lead neutral experts committee. • To install a French and unique network of experts that can be consulted by all ORE stakeholders.

Variability in the predicted cost of energy of an ocean energy converter array is more substantial than for other forms of energy generation, due to the combined stochastic action of weather conditions and failures. If the variability is great enough, then this may influence future financial decisions. This paper provides the unique contribution of quantifying variability in the predicted cost of energy and introduces a framework for investigating reduction of variability through investment in components.
