Celtic Sea Floating Offshore Wind
Case History
In 2021 the Crown Estate began exploring options for a fifth offshore wind leasing round, focused on floating wind technology within the UK Celtic Sea.
In October 2022, following consultation with developers, five refined areas of search for potential development were published and in October 2023 a further announcement was made identifying three Project Development Areas (PDAs).
Project Description
In 2022, GeoProvider undertook a legacy 2D seismic reprocessing and repurposing project, covering all the original proposed areas of search within the UK Celtic Sea.
GeoProvider’s bespoke repurposing workflow was applied using a 2 millisecond sample rate and included proprietary methods for broadband processing and bandwidth optimization.
The aim of the projects was to gain greater understanding of the seabed and subsurface risks enabling offshore wind developers to make well informed, evidence-based planning decisions and to submit successful lease applications.
Outcomes
High resolution broadband reprocessing has successfully improved seismic image resolution in the crucial seabed and near surface areas aiding interpretation of geological structures and geohazards. Features identified include exposed tunnel valleys and channel infill structures. Reprocessing and repurposing has delivered data suitable for identification of seabed and subsurface hazards from seismic data previously suited only to deeper imaging purposes
The example section below shows the resolution uplift achieved compared to the original standard resolution data:
