National Grid is an international Electricity and Gas Network Company based in the UK, with
operations in north-eastern US. And one of the largest investor-owned energy companies in
the world.
National Grid are looking to set up a multi-year Marine Survey Framework to service offshore
cable laying as part of the Great Grid Upgrade and may be utilised in the future for any
Hydrogen Pipeline projects as applicable.
The Framework will cover the full gamut of survey disciplines required for cable lay and
subsequent maintenance. Including Geophysical, Geotechnical, Environmental,
Intertidal/landing, Unexploded Ordinance, Maintenance with flexibility to award Turnkey
requirements.
The Framework is seen as being an important part of National Grid's maritime requirements
to allow for a more rapid contracting of surveys potentially in parallel with other project
elements that traditionally have been programmed sequentially.
All data and associated metadata resulting from these surveys will be required to fall in line
with relevant UK and international standards such as IHO S44, EUNIS and MEDIN to enable
data archiving and sharing as required.

National Grid has committed in our Climate Transition Plan to achieve close to zero
emissions by 2050 and science based intermediary targets aligned to a 1.5 degree pathway
for our UK Electricity Transmission, System Operator and Distribution businesses. To
achieve this ambitious target, we need to ensure all our suppliers are on a similar path and
this Framework will look to leverage novel and autonomous technologies to achieve this.
The Framework will look to incentivise companies on the Framework to reduce the project
footprint where possible. All projects will also require the companies to provide accurate
carbon footprint reporting.
