[OECfne_2-06]Conceptual Design of a Digital Twin-Based Integrated Framework for Subsea Infrastructure Management
*Sujin Son1 (1. Sundosoft Co., Ltd. (Korea))
With the expansion of offshore wind farms and subsea power and communication networks, various types of subsea infrastructure - including submarine cables, pipelines, and artificial reefs - are continuously increasing in Korean waters. However, information on these assets, such as location, burial depth, permitting, and maintenance records, is managed separately by different organizations, limiting efficient management and spatial decision-making. As marine biodiversity conservation becomes a significant issue in the installation and management of such structures amid the climate and biodiversity crises, the demand for systematic marine spatial planning (MSP) is expected to grow. This study defines subsea infrastructure as interoperable digital objects and designs a digital twin-based integrated framework linked with MSP.
The framework standardizes core data elements for submarine cables, pipelines, artificial reefs, and subsea structures, and represents each asset as an interoperable operational digital object by integrating location and facility attributes, permitting, inspection, maintenance, and risk information, together with heterogeneous geospatial data such as electronic navigational chart-based bathymetry, seabed topography, field survey data, and public water occupancy permits. The digital twin environment provides 3D visualization, spatial analysis, and site suitability assessment to support integrated management and spatial decision-making.
In particular, overlay analysis with key MSP layers - marine use zones, protected species habitats, marine protected areas, and regulatory zones for safety and defense - enables pre-installation review of spatial conflicts and risks, while supporting integrated management of existing facilities' conditions and maintenance histories. The framework thus consolidates distributed information into standardized digital objects, functioning as a decision-support system across the full lifecycle of planning, installation, operation, and maintenance.
In the second year, a pilot dataset will be developed for a demonstration area, integrating real-time monitoring, marine environmental observations, and field survey data to realize an operational ocean digital twin, ultimately supporting national subsea infrastructure management and marine spatial policy.
