Summary of the contracting process

The National Grid Interconnector Holdings Ltd and Elia Asset SA are developing proposals for a High Voltage Direct Current (HVDC) interconnector project named "Nautilus" between England and Belgium in the services category. The procurement process, which started with a cancelled tender, involves marine survey services to establish a preferred route alignment for the 200km HVDC interconnector installation. The tender is currently at the active stage and offers opportunities for businesses in marine survey services.

This tender by National Grid Interconnector Holdings Ltd and Elia Asset SA for the "Nautilus Marine Survey" presents opportunities for businesses in services related to marine geophysical and geotechnical surveys. The procurement process, which has a selective procurement method, is seeking suppliers for various lots including geophysical cable & platform, and geotechnical services for different periods. Interested parties are invited to register their interest and obtain pre-qualification documentation to participate in the tender process.

Notice Title

Nautilus Marine Survey

Notice Description

Discontinuation of the procurement process for the following project: National Grid Interconnector Holdings Ltd and Elia Asset SA are currently developing proposals for a High Voltage Direct Current (HVDC) interconnector "Nautilus" between England and Belgium in support of ongoing programs for strengthening both the UK and Belgian Transmission Networks. The development process has identified the need for a HVDC Interconnector installation over a cumulative distance of approximately 200km. Survey requirements are thus arisen to establish suitability of a preferred route alignment.
