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

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.

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

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 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 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 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 details the algorithms for implementation of the effects of array changes on device cost
