Abstract
Digital Twins of the Ocean (DTOs) are increasingly used in Maritime Spatial Planning (MSP), yet most remain limited to 2D representations and offer minimal stakeholder interactivity. These limitations reduce their effectiveness in capturing complex socio-ecological-technical dynamics and supporting exploratory what-if scenario planning in a 3D or 4D ocean space. This paper presents Immersive Ocean, a novel Virtual Twin platform developed within EU-ILIAD DTO initiative. Built with game engine and VR technologies, it supports procedural 3D world generation and interactive exploration in both desktop and immersive VR modes. Systematic performance validation demonstrated stable frame rates across both PC and VR platforms. Initial user evaluations (n=22) report high usability and engagement but also suggest areas for improvement in UI clarity and ecological model representation. These initial findings position Immersive Ocean as a promising Virtual Twin solution for an immersive, interactive, and data-integrated approach to MSP and ocean governance. Immersive Ocean is now being piloted with stakeholders in real-world MSP scenarios, including offshore wind farm planning.
