This article studies the feasibility of combining a spar-type offshore wind turbine - inspired by Hywind - and a wave energy converter - inspired by Wavestar - by performing numerical simulations in operational conditions

This report presents the project repository for DTOcean is hosted by Joint Research Centre within the SETIS website to ensure long-term exploitation of the tools developed during the project and related documents

This document extensively reviews the key offshore logistics operations driving the development of an array of wave or tidal energy devices. A large amount of information with relevance for the development of the DTOcean lifecycle logistics module was compiled in a systematic approach.

This deliverable presents the results from the assessment of existing array level operation, maintenance and control methods and tools. Potential sources of knowledge for this are the onshore and offshore wind industry and the offshore oil and gas industry. Offshore wind farms face very similar challenges with respect to foundations, submersed electrical systems, personnel and vessel access to array devices, transport of materials, etc. The offshore oil and gas industry has worked with floating or bottom fixed concrete and steel structures for several decades. Main experiences analysed here are related to corrosion problems and long-term stability of mooring systems. Control and operational strategy aspects were also assessed

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

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

The objectives of the DTOcean project were: • To accelerate the industrial development of knowledge related to wave and tidal energy production. • To provide design tools for the deployment of the first generation of ocean energy systems.

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

This report presents the uncertainties and environmental impact dependencies on array changes. This document includes content about wave and tidal uncertainties as well as environmental issues related to array design

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
