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.

This document serves as the technical manual of the alpha version of the system performance and energy yield module, including all the data requirements, main functions, interfaces and all the pertinent technical details.

The DTOceanPlus project has develop an open-source integrated suite of 2nd generation design tools for ocean energy technologies. The tools support the entire technology innovation and advancement process from concept, through development, to deployment, and is applicable at a range of levels: sub-system, device, and array. As one of the first tasks in the project, researchers at The University of Edinburgh conducted a consultation exercise, with the support of DTOceanPlus partners. This consultation addressed potential users and other key stakeholders for the DTOceanPlus tools, to identify and clarify their needs and requirements. A webinar was held initially, to introduce both the DTOceanPlus tools and the consultation. In addition to an online questionnaire, a series of individual interviews were held to obtain more nuanced input from key stakeholders. Opinions from over 70 industry professionals from a wide range of backgrounds were collated and analysed as part of the consultation. This includes representation of the four stakeholder categories identified: - Public funders, commercial investors, and insurance providers, - Innovators and developers, - Project developers, utilities, and supply chain, and - Policy makers, regulators, and standardisation bodies. Of the overall software characteristics considered, usability followed by flexibility & expandability then modularity were seen as most important. The proposed tools will need to deal with varying degrees of complexity, both at different stages in the project lifecycle and also for different user requirements. Several responses stressed the importance of linkages between the tools, and with external software. Nearly all respondents (>85%) indicated that they were likely or very likely to use DTOceanPlus at some stage in the project lifecycle. The results from the consultation exercise are presented in this report.

This report describes the methodology used to define the “validation scenarios”, accounting for the different potential use cases. Given the large number of permutations of tools, use cases, and the set of minimum validation requirements, the number of validation scenarios has been reduced to a number that can be run during the life of the DTOceanPlus project but that are sufficient to fully demonstrate the functionality of the DTOceanPlus suite of tools. The selection process, based on a successive approximation approach, has led to the cases that the potential users in the DTOceanPlus consortium have considered as the most relevant for the sector. In Section 4 of the document, the selected validation scenarios is described; the definition of these scenarios has been completed during the project to ensure that the most updated information is used.

A coherent set of requirements have been developed for the DTOceanPlus suite of design tools based on analysis of gaps between the current state-of-the-art tools, learning from the DTOcean project, and the stakeholder expectations identified in the user consultation exercise. The requirements in this document are split into general requirements for the overall suite of tools, and specific requirements (functional, operational, user, interfacing, and data) for each of the design tools that is developed as part of this, which are split by work package and task. They act as user specifications for the tool development work packages, and focus the development effort to best meet the needs of the ocean energy industry. Subsequent tasks of the DTOceanPlus project develop these requirements into more detailed technical requirements and software specifications, prior to software coding and integration, then testing and validation.

A coherent set of functional and technical requirements have been developed for the DTOceanPlus suite of design tools based on analysis of gaps between the current state-of-the-art tools, learning from the original DTOcean project, and the stakeholder expectations identified in the user consultation survey. The technical requirements in this document are translated from the general requirements for the overall suite of tools, and specific requirements (functional, operational, user, interfacing, and data) for the Structured Innovation design tool that has been developed as part of this project. These requirements relate to detailed technical requirements of the technology and environment, for the development, maintenance, support and execution of the software specifications to best meet the needs of the ocean energy industry.

A coherent set of requirements have been developed for the DTOceanPlus suite of design tools based on analysis of gaps between tools in mature industries and those in the ocean energy industry, learning from the original DTOcean project, and the stakeholder expectations identified in the user consultation exercise. The technical requirements in this document are translated from the general requirements for the overall suite of tools, and specific requirements (functional, operational, user, interfacing, and data) for the Stage Gate design tool that will be developed as part of this project.

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.

The Structured Innovation (SI) design tool forms part of the DTOceanPlus suite of second-generation open source design tools for ocean energy. The SI tool comprises innovation methodologies which can enhance concept creation and selection in ocean energy systems (including sub-systems, energy capture devices and arrays), enabling a structured approach to address complex ocean energy engineering challenges where design options are numerous, and thus it can facilitate efficient evolution from concept to commercialisation.

This document collects the main guidelines, standards and procedures applicable to the implementation of the tools and modules in the DTOcean+ suite.
