This document serves as the technical manual of the alpha version of the reliability, availability, maintainability and survivability module, including all the data requirements, main functions, interfaces and all the pertinent technical details.

This report describes the compilation of required data inputs for the various validation scenarios. Each scenario is characterised through a set of project data, inherent to the technology as well as meteocean conditions and other location related data. Further engagement with the validation leaders is ensuring that the data is adequately formatted for the purposes of running the DTOcean+ tools.

Ocean energy is a relevant source of clean renewable energy, and as it is still facing challenges related to its above grid-parity costs, tariffs intended to support in a structured and coherent way are of great relevance and potential impact. The logistics and marine operations required for installing and maintaining these systems are major cost drivers of marine renewable energy projects. Planning the logistics of marine energy projects is a highly complex and intertwined process, and to date, limited advances have been made in the development of decision support tools suitable for ocean energy farm design. The present paper describes the methodology of a novel, opensource, logistic and marine operation planning tool, integrated within DTOceanPlus suite of design tools, and responsible for producing logistic solutions comprised of optimal selections of vessels, port terminals, equipment, as well as operation plans, for ocean energy projects. Infrastructure selection logistic functions were developed to select vessels, ports, and equipment for specific projects. A statistical weather window model was developed to estimate operation delays due to weather. A vessel charter rate modeling approach, based on an in-house vessel database and industry experience, is described in detail. The overall operation assumptions and underlying operating principles of the statistical weather window model, maritime infrastructure selection algorithms, and cost modeling strategies are presented. Tests performed for a case study based a theoretical floating wave energy converter produced results in good agreement with reality.

The Structured Innovation (SI) design tool comprises innovation methodologies that can enhance concept creation and selection in ocean energy systems, enabling a structured approach to address complex ocean energy engineering challenges where design options are numerous. Thus, it can facilitate efficient evolution from concept to commercialisation. The tool is one of a kind beyond the current state-of-the-art, that will enable the transfer and adaptation of the QFD/TRIZ and FMEA methodologies to the ocean energy sector.

Deliverable D4.2 “Stage Gate Tools – alpha version” of the DTOceanPlus project includes the details of the Stage Gate Design Tool, and it represents the result of the work developed during task T4.2 of the project. This tool is an application of a stage gate process which is used in research and industry to provide structure to the technology development process. This approach supports the R&D pathway towards producing reliable and cost-effective ocean energy sub-systems, devices and arrays.

This deliverable is a report documenting the outcome of the work carried out to deliver an overview of the outcomes of the verification tasks since the feedback from the users’ experience will be useful to improve the performance of the tools beyond the project end. The results of the validation scenarios, based on the feedback produced by the partners, will generate useful recommendations for the stakeholders willing to improve global performance of ocean energy arrays, single devices or critical components and subsystems. The work developed throughout the validation tasks will benefit from DTOcean+ tools to perform several activities, articulated in the respective reference validation scenarios, both for wave and tidal energy.

This report collects the outcome of the work carried out to fully describing the data used for a generic ocean energy system design in a structured manner. This has been done by means of the definition of a digital representation for the elements of the whole system at different levels of aggregation (array, devices, sub-systems, and components) and accounting for different levels of complexity of the project. The ambition of the present framework is to standardise the data formats describing an ocean energy design so that it can be used as a common interchange language among different sector actors

This report is the outcome of a feasibility and cost-benefit analysis. The aim of this task was to conduct an economic feasibility and cost-benefit analysis, to assess the technologies and funding frameworks to support attractive business cases for both public and private funders.

This document is an update of the first version of the data management plan. This version describes in more detail the practical data management procedures implemented by the DTOceanPlus project.

Deliverable D5.2 “Site Characterisation – alpha version” of the DTOceanPlus project include the details of the Deployment Tool module: “Site Characterisation” (SC), and it represents the result of the work developed during the task 5.3 of the project. This document summarises both the functionalities as well as the more technical aspects of the code implemented for this module.
