The marine geophysical surveys off the coast of Copeland,
Cumbria, which are set to begin in the summer of 2022, are
non-intrusive and will provide a better understanding of the rock
structure to help inform the search for a suitable site for a
Geological Disposal Facility (GDF).
The data-gathering programme will use a vessel carrying
specialist acoustic equipment deployed between 5 and 20km from
the coastline. The work will take place over a period of three to
four weeks and will be undertaken by specialists Shearwater
GeoServices, who were awarded a £6 million contract by Nuclear
Waste Services (NWS) following a procurement process.
The survey is an important early step in beginning to understand
the deep geology beyond the coast. This first survey is focused
off the coast of South and Mid Copeland.
The technology deployed from the 92-metre vessel is based on
sound waves – similar to ultrasound scans used for medical
purposes - which are reflected as an echo from different
geological layers. This enables a 3D picture of the underlying
rocks to be gradually built up. The seabed itself remains
undisturbed. Surveys of this type are commonplace in the offshore
wind, oil and gas sectors.
The GDF team will work with marine representative bodies and
other stakeholders to keep marine users and local communities
informed of developments.
Chris Eldred, Head of GDF Geosphere Characterisation, said:
We are looking forward to the commencement of the first surveys
this summer off the south west coast of Copeland, working with
the specialists at Shearwater GeoServices.
The information we gather will help us to further consider the
suitability of areas to host a GDF and support informed dialogue
with the communities that are at the heart of the siting process.
Data from the surveys will need to be processed and analysed in
detail which will take about nine months during which time we
will consider how or if further survey work is needed. The
information will give our geologists and engineers some of the
tools they need to begin designing and planning the next steps in
the search for a suitable site for a GDF.
