two.1.4) Short description

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.

Page 4 to 37

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.

magnetometer for some projects. This work includes data collection from the intertidal area

to offshore and involves a comparison of data from previous surveys. Autonomous platforms
