This document is the first annual report on dissemination and communication activities regarding DTOceanPlus 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 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 report is the outcome of an analysis of potential markets for ocean energy technology. The aim was to develop a greater understanding of the potential markets for the deployment and the exploitation of these technologies. The focus includes both the present market status and future opportunities for commercialisation of both grid and non-grid applications.

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

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

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.

The present document refines the previous version submitted in October 2019, updates the initial assumptions, and depicts more clearly the exploitation routes and actions to reduce risks.

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.

This document summarizes both the module functionalities and the more technical aspects of the code implemented in the station keeping module.
