London Array Offshore Windfarm
Benthic Monitoring
Project Description

We have recently completed the three-year post-construction benthic monitoring programme required as part of the Marine Licence conditions for the London Array (LAW) Offshore Windfarm located in the outer Thames Estuary. This substantial programme at the world’s largest operational offshore wind farm involved collection of grab and trawl samples at nearly 300 locations followed by all of the associated macrobenthic and Particle Size Distribution (PSD) sample analysis to test for potential impacts within the wind farm and its environs as well as areas in close proximity to the turbines themselves.
We subsequently conducted a detailed analysis of datasets spanning the pre- and post-construction periods to validate the predictions made during the Environmental Impact Assessment (EIA). All project outputs were successfully delivered on time and budget and we were praised for the high quality and Health and Safety standards demonstrated throughout the contract.

Ocean Ecology completed the post-construction surveys successfully with high quality of deliverables. The Ocean Ecology team is flexible and were able to adapt to changing conditions and sampling approaches at short notice to help to ensure the compliance with the Marine Licence conditions. It was especially appreciated that when any challenges or ambiguities arose, solutions were also proposed in a timely and pragmatic fashion. As a client, minimal effort was required on our side of the project to manage Ocean Ecology. The project leads displayed excellent technical knowledge with the necessary enthusiasm and commitment to support collaboration and were professional at all times.
