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

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

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

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

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 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

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
