This document delivers the Blue-Cloud 2026 Joint Exploitation Plan. It outlines the exploitation strategy, objectives and measures that will be deployed to support the long-term exploitation of the results stemming from the HE Blue-Cloud 2026 project, jointly by Consortium Partners. The Plan focuses on the exploitation of the Blue-Cloud 2026 services and assets as a synergetic digital ecosystem, encompassing and connecting identified Key Exploitable Results, namely: Blue-Cloud 2026 Virtual Research Environment; Blue-Cloud 2026 Core and Generic Services; Blue-Cloud 2026 Spatial & Data Management Services; Blue-Cloud 2026 High Value Thematic Services; Blue-Cloud 2026 Training Courses & Materials; Blue-Cloud Strategic Roadmap to 2030. The Blue-Cloud 2026 Consortium has identified a strategic pathway for long-term exploitation of its open science ecosystem as a marine thematic node within the European Open Science Cloud (EOSC) (see section 2). In this framework, Blue-Cloud's built know-how and results will be harnessed to bridge EDITO -the public infrastructure of the European Digital Twin Ocean- to EOSC, contributing to support major EU marine data services -such as EMODnet and Copernicus Marine- and related EDITO knowledge assets in driving data provision into EOSC. The output knowledge and assets generated in Blue-Cloud, including its underpinning infrastructure, will be used to contribute to consolidate a marine thematic node in EOSC, establishing the conditions that can guide the transition towards becoming a core component of the EDITO program, for long-term sustainability. Within this overall framework, the following Exploitation Objectives (EO) are envisioned (see section 3), across key assets (described in section 4) and a range of key target users (described in section 5): EO1: Institutional integration in the EOSC Federation; EO2: Uptake of existing core, generic and thematic services by users working in the marine and aquatic domains; EO3: Uptake of existing core and generic services by other EOSC nodes, supporting the development of the EOSC Federation; EO4: Marine knowledge landscape alignment and added value contribution; EO5: Community engagement, capacity building & representation. To achieve these objectives, a number of exploitation measures have been defined, and resources required for execution have been either committed or identified (Section 6), towards long-term, sustained impact beyond the project lifetime. Exploitation targets have been established (Section 7). The delivery of a marine thematic node will contribute to shortening the research-to-innovation cycle, enabling its users to harness artificial intelligence (AI) to catalyse the transformation of marine data to products, and foster cross-discipline collaboration. In the long term, it will contribute to enhancing existing marine knowledge, science-to-policy interfaces, and to informing science-based ocean management and governance in support of Mission "Restore Our Ocean & Waters" and related EU policies and strategies.
