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 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 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 report presents the evaluation according to costs estimation of different maintenance strategies

With the DTOcean software at an important stage in its development, the first of two training workshops foreseen by the project was organised on 5 May 2015, in Glasgow, alongside the All-Energy conference. The workshop was organised with the following goals in mind: validate decisions taken to date with industry stakeholders; generate feedback which will further align the tool with industry needs; and promote the DTOcean tool and enhance its eventual uptake as a result

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 deliverable includes the proposed logistic model architecture in terms of flow charts, including data flows within the model and with other DTOcean modules and external databases and tools.

This deliverable presents the 1st report on dissemination and communication activities. It is a did term review

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

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
