Case Study: Rampion Offshore Wind Farm Cable Route Engineering
Pelagian provided a detailed GAP Analysis, cable route engineering and cable burial risk assessment consultancy services to the Rampion Offshore Windfarm.
Project work included the design and layout of the export and array cables and geospatial data management and expert recommendations for suitable cable burial equipment and techniques to inform the tendering process prior to cable installation.
The route engineering encountered challenging seabed conditions requiring the careful planning of the wind farm array cables in 20-40m of water around planned jack up locations and avoiding underlying paleochannel areas.
Case Study: Personnel and Consultancy Services for Hibernia Express
Pelagian provided expert consultancy services and personnel to the Hibernia Express project, the first trans-Atlantic telecom cable to be installed for over 10 years on a unique low latency route laid in very challenging seabed conditions.
Pelagian’s consultancy services included the management of survey and installation programs, permitting research and stakeholder management including the preparation of Notice to Mariners and information for the public.
During the 2 year project, Pelagian provided key personnel for the survey and installation campaigns and contributed to the success of the Hibernia Express project, which was awarded “Project of the Year – Subsea” and “Best Subsea Innovation” at the Global Carrier Awards in 2015.
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.
