The aim of this document is to present the activity carried out by the four industrial partners who validated the DTOcean+ suite against five wave energy validation scenarios.

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

This report is the outcome of a task dedicated to specific sector standards for business management models for the ocean energy sector. The aim of this task was to define alternative business models for the sector by developing a greater understanding of these models and recommending development routes to industrial roll-out to improving the market opportunity.

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 document includes the details of the logistics and marine operations module of the deployment design tools. This module is responsible for designing and planning the project lifecycle phases of an ocean energy project. Reflecting the most recent experiences and best practices of the offshore wind sector, this module produces integrated solutions in respect to logistic infrastructure, comprised of vessels, equipment and ports, as well as operation durations and costs based on introduced historical weather data.

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.
