UK Public Sector Contracts & Tenders

The general requirement is for targeted marine surveys of 5 specific areas (see map) between Aldeburgh (East Suffolk) and Pegwell Bay (Kent), to supplement a survey of the whole route undertaken in 2021, to inform of seabed morphology and shallow sediment structure, and to provide benthic characterisation and habitat maps. The PQQ process is to establish market capability to carry out the required works within the time period indicated. It is the Client's intent to follow up the PQQ responses with a tendering process with a view to award a Marine Seabed Survey contract based on a detailed RFP process. The survey scope of work covers geophysical, geotechnical and environmental sampling. In addition to the 5 survey areas, the scope of work may potentially include an additional off-shoot survey of the main route in the near future.

As part of the ongoing Operations and Maintenance, an interim depth of burial marine survey needs to be produced which is specific to the parts of the cable route which demonstrates industry best practice for bathymetric and geophysical surveys. The general requirement is for a marine bathymetric and geophysical survey along an approximately 390km route comprising two separated cables from Hunterston in Scotland to the Wirral, England over an approximately 80m wide corridor. The interim surveys are of areas of interest e.g. crossings, areas of mobile sediments and intense fishing etc. and comprise approximately 30-50% of the total route length.

As part of the Eastern Green Link Projects (EGL 3 & EGL 4) new connections will increase the capability of the electricity transmission network between England and Scotland. The general requirement is for a marine survey of two cable routes to inform of seabed morphology and shallow sediment structure, and to provide benthic characterisation and habitat maps. The planned marine cable routes are both East Coast UK, from Peterhead to Lincolnshire and from Fife to Lincolnshire. Lotting of the Requirements: • Lot 1- EGL 3 Marine Cable Route Survey: approximately 500 km route from Peterhead to Lincolnshire • Lot 2 - EGL 4 Marine Cable Route Survey: approximately 450 km route from Fife to Lincolnshire There may be parts of the EGL 3 and EGL 4 routeing which are similar and may be surveyed as one. Therefore, these Lots may be reduced in surveyed length by up to 150 km. The survey scope of work covers geophysical, geotechnical, topographic and environmental sampling. To register your interest in this Procurement event and to obtain the pre-qualification documentation applicants are to email Rebecca.Pearson@nationalgrid.com using the wording 'Registering Interest for EGL 3 & 4 Marine Surveys and include in the body of the message (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.

The Call for Innovation (CFI) is an approach to the market to see what products and services are available in the industry with funding coming from Ofgem's Network Innovation Allowance. A CFI is not a formal competitive tender process but is an approach to the market with a specific problem statement or topic of interest that National Grid would like to hear ideas about from the marketplace. All information received will be used to consider whether we want to engage with a specific supplier or whether we believe a competitive tender approach is required. Essentially this CFI will inform or dictate our procurement strategy.

National Grid Electricity Transmission (NGET) is seeking collaboration with universities to support delivery of its innovation strategy over the next five years (April 2026 - Mar 2031). The primary objectives during this period include facilitating the energy system transition (including Clean Power 2030 and net zero 2050) and providing support for vulnerable consumers. University partners will be expected to contribute both resources and technical expertise to the development and execution of Research & Development (R&D) projects. We expect universities to run projects within Technology Readiness Levels 2 to 8 which includes research, development and demonstration projects. These initiatives will enable NGET to ensure a safe and reliable electricity network, enhance consumer value, achieve decarbonisation of future networks, and create a positive impact on society. NGET will invite universities to propose new projects that address specific needs, while also encouraging the generation of innovative project ideas. In addition to individual innovation projects, partners will play a crucial role in fostering innovation through strategic development, knowledge sharing and promoting an innovation-driven culture. Knowledge sharing may include supporting NGET in running dissemination events across the energy sector and other industries to communicate the outputs, learnings and benefits from projects, as well as using these events to learn from others.
