Summary of the contracting process

The National Grid UK Limited, a prominent electricity and gas network company, has initiated a Marine Survey Framework procurement process under the Open Contracting Data Standard (OCDS) with the aim of supporting offshore cable laying and future hydrogen pipeline projects. As of 22 September 2025, the buying organisation is focused on the "Marine Survey Framework" tender, classified under marine survey services (CPV code: 71354500). This framework is integral to the Great Grid Upgrade and spans various UK and international regions, including BE, DK, FR, DE, IS, IE, NL, NO, ES, and SE. The procurement stage recently reached the award conclusion, with the announcement of contracts on 16 June 2025. The ongoing framework will adhere to UK and international standards, such as IHO S44, EUNIS, and MEDIN, for data and metadata compliance.

This tender offers significant opportunities for businesses specialising in geophysical, geotechnical, environmental, intertidal/landing, and unexploded ordnance surveys, among others. The procurement method used was a selective, negotiated procedure with prior competition, which allowed for direct engagement with interested suppliers. Funding worth up to £250 million and potential contract renewals offer extensive prospects for companies in this sector. Businesses leveraging novel, sustainable technologies, such as autonomous vessels, which align with National Grid's climate targets, are particularly well-positioned to participate in this strategic framework. The tender encourages robust carbon footprint reporting and project footprint reduction, catering to entities capable of providing comprehensive survey services nationally and internationally.

Notice Title

Marine Survey Framework

Notice 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. To register your interest in this Procurement event and to obtain the pre-qualification documentation applicants are to email: box.gp.ukbuyerngv@nationalgrid.com using the wording 'Registering Interest for Marine Survey Framework (if you have them) your Ariba AN number (Network ID), name, email address and contact phone number for all contacts within your organisation who will need to receive Ariba messages and administer your online submissions.

It is expected that this will generally utilise Multi-Beam Echo Sounders and backscatter, as well as Side Scan Sonar and 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 to reduce the carbon footprint of the operations would be considered for this work and other novel approaches aimed at reducing the carbon footprint of the projects are desirable.
