Deliverable 1.1 presents the first draft of the design framework for the DTO data products and services that will be developed within the project. This report details the co‑design process carried out jointly by project developers, user partners (Vattenfall and ESTEA), and the Stakeholder Advisory Board (SAB).
The work focuses on two key areas:
To support this process, a structured 19-question survey was deployed to all 10 member organizations of the SAB to capture user needs and refine product and service specifications, achieving a 100% response rate to establish a clear baseline of industry and research priorities. The survey yielded several critical insights that directly shape the project's development scope:
● Primary Applications: Environmental and metocean data are most critically needed for design and certification decisions (80% of respondents) and site selection (60%).
● Key Data Gaps and Uncertainties: Sea ice represents the parameter of highest uncertainty (70%), followed by currents (40%). Stakeholders identified spatial coverage and the representation of extreme events as the most significant data gaps (60%).
● Dataset Continuity: A total of 70% of respondents consider long-term dataset consistency (>20 years) essential for defining engineering design bases and lifetime assessments.
● Analytical Approach: Uncertainty information is currently handled qualitatively by 60% of the industry, reinforcing a demand for balanced systems that pair robust baseline standards with advanced predictive capabilities.
Based on these outcomes, the framework confirms excellent alignment between stakeholder demands and the planned DTO4OWE technical deliverables. The core focus will be directed toward delivering high-resolution (~1–2 km) regional metocean hindcasts (2010–2020), mid-century climate projections, extreme event statistics, and sub-regional DTOs for the Baltic and North Seas, positioning DTO4OWE clearly as a process-based, scenario-driven decision support tool.
