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

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

In order to make an informed decision on which tools to use for hydrodynamic analysis of array layouts of ocean energy converters, an assessment of capabilities of available tools has been carried out and is presented in this report both for wave energy converter arrays and tidal energy converter arrays

In this paper, the applicability of offshore mooring/foundation technologies for marine renewable energy device arrays are assessed

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 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 provides an introduction to the architecture of the installation module within the DTOcean global tool

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.

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

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