## Summary

The procurement process for the contract "LionLink Marine Survey" was carried out by National Grid Ventures. The industry category is marine survey services, and the procurement stage was completed under the selective procurement method with a negotiated procedure. The tender involved conducting a marine geophysical survey and shallow marine geotechnical survey for a proposed HVDC Interconnector project between England and the Netherlands over a 200km distance.

This tender presents growth opportunities for businesses specializing in marine survey services, geotechnical engineering, and related consultancy services. Companies experienced in conducting marine geophysical surveys, sediment sampling, and geotechnical lab testing would be well-suited to compete. National Grid Ventures, based in London, led the procurement process and awarded the contract for the tender to Next Geosolutions UKCS Limited.

## Notice

National Grid Interconnector Holdings Limited and TenneT are developing proposals for a High Voltage Direct Current (HVDC) Multi Purpose Interconnector "Lion (Euro) Link" between England and Netherlands in support of ongoing programs for strengthening both the UK and Dutch Transmission Networks. The development process has identified the need for a HVDC Interconnector installation over accumulative distance of approximately 200km. Survey requirements are thus arisen to establish suitability of a preferred route alignment.
