Green Marine UK has taken a decisive step in the environmental monitoring of offshore wind farms by expanding its PAM device service in response to agreements reached with the Scottish Government’s Marine Authority. This expansion allows the company to offer “full scope” projects, marking a significant advance in the UK’s marine energy sector.
PAM devices for the protection of the marine ecosystem
After 18 months of continuous work and operations in distant waters up to 250 nautical miles, Green Marine has managed to recover approximately 40 PAM (passive acoustic monitoring) devices . These devices, equipped with hydrophones, make it possible to record the activity of migratory fish and marine fauna, which is crucial for the development of sustainable projects .
With this technology, wind farm developers and environmental authorities can meet marine ecosystem protection standards, a priority objective in the United Kingdom, the second largest offshore wind energy market in the world.
Orkney-based Green Marine started out offering vessel charter services but has expanded its capabilities to include the deployment and recovery of advanced acoustic devices. The company also collaborates on “catch and tag” projects to study fish movements and improve knowledge of the marine ecosystem.
Green Marine leads in offshore environmental monitoring
Chief Operating Officer and Technology Officer Myles Metson highlighted the growing demand for environmental monitoring in the UK wind energy market. He also assured that the company will continue to strengthen its collaboration with strategic partners to cover all phases of monitoring, from device deployment to data processing.
Last summer, Green Marine successfully completed four projects off the Scottish coast , supporting the NNG and Seagreen wind farms . It is already booked for new projects in the final quarter of this year.
Green Marine project engineer Steven Waddell highlighted the complexity of the PAM recovery work, noting that each operation requires extensive ship handling expertise and specialised equipment. In areas of high ecological sensitivity, they even use remotely operated vehicles (ROVs) to minimise the impact.
This expansion of services consolidates Green Marine as a benchmark in the protection of the marine environment, aligning with the United Kingdom’s plans to reach 50 GW of offshore wind capacity by 2030.
