## Summary

The Scottish Government, headquartered in Glasgow, is seeking tender submissions for ecological sampling at Scottish Offshore Wind Farms. This procurement falls under the general public services category and involves marine sampling at four offshore wind farm sites on the east coast of Scotland. The project, set to begin on 5th January 2026 and conclude by 31st March 2027, will span three phases: winter 2025-spring 2026, summer 2026, and autumn 2026. The tender process, currently in the tender stage, is being conducted via an open procedure, with key submission deadlines culminating on 10th November 2025. This project is part of the broader ECOCHANGE Project and is expected to contribute valuable insights into marine biodiversity and the impact of offshore wind farm infrastructure.

This tender presents significant opportunities for businesses specialising in environmental services, marine biology, and ecological research. Companies with expertise in marine sampling and environmental impact assessment, particularly those equipped to manage large-scale ecological studies, will find this project well-suited to their capabilities. Additionally, businesses that demonstrate strong environmental management practices and a commitment to sustainability and community benefits will be particularly competitive. The open procurement method allows various companies to participate, offering competitive pricing and innovative solutions that could drive business growth and contribute to achieving Net Zero targets through sustainable development of offshore wind infrastructure.

## Notice

The Marine Directorate (MD) has a requirement for an external provider to undertake marine sampling for a selection of target species across a range of functional groups (e.g. fish, benthic and plankton) at four offshore wind farm sites and adjacent control areas, on the east coast of Scotland. Sampling will be carried out across 3 phases: winter 2025-spring 2026 , summer 2026 and autumn 2026. This sampling work will contribute to the ECOCHANGE Project (Consequences of Changes to Habitats and implications for a Net Gain Energy approach), led by the Scottish Government's Marine Directorate, alongside the University of Liverpool the University of Glasgow SUERC and funded by The Crown Estate's Offshore Wind Evidence and Change programme. The samples collected through this work will be analysed through a subsequent workstream (not included in the scope of this contract) and the data will ultimately provide insight into the food web structure within the North Sea marine ecosystem and how food webs may be impacted by OWF infrastructure. Understanding this relationship is crucial with the increase in development of OWFs to reach Net Zero targets. This work will shed light on the effect of OWF infrastructure on marine biodiversity which will inform Marine Enhancement and Nature Positive policies.
