Case Study: Gwynt Y Mor Cable Engineering and Data Management Services

Pelagian were contracted to provide detailed route engineering and cable burial risk assessment advice for the Gwynt Y Mor offshore wind farm project. This involved working with both the developer and cable installation companies to provide expert analysis of the seabed hazards for cable routes and wind turbine generator (WTG) foundations.
Project work included the collation of 10 years of geophysical survey data into a unified geospatial dataset, which was used to inform the export and array cable route planning and also construction phase works.
Pelagian’s knowledge of the project and expertise in handling this geospatial data greatly assisted in the planning of WTG construction and cable lay operations, while forming the basis for the developer’s own geographical information database and marine management systems.
