Possibility for North Sea gas platform to be repurposed as seabird nesting site

Published on September 5, 2022

Alpha Petroleum, Energean UK and Orsted agree to explore the repurposing of a UK Southern North Sea
gas platform as a potential compensation measure for offshore wind.

The provision of artificial nesting sites is considered a viable compensation measure for the potential impact
of offshore wind development on certain seabird species, including the black-legged kittiwake (kittiwake).
Kittiwake have been observed readily utilising man-made structures and Orsted’s recent offshore surveys
of platforms in the North Sea have shown large numbers of nests on a number of platforms.

Orsted engaged extensively with installation owners in the Southern North Sea to identify candidate
platforms, while undertaking its own survey to confirm the distribution of nesting kittiwake colonies across
gas facilities in the area. The surveys also assessed the suitability of the platforms to provide compensation
while taking into account their respective decommissioning timeframes and the willingness of platform
owners and operators to consider adapting plans to facilitate innovative repurposing.

Kittiwake nesting on the Wenlock platform in the southern North Sea

The Wenlock platform has an established kittiwake colony with around 69 apparently occupied nests
counted in the June 2022 survey – an increase on past counts. The platform is nearing the end of its economic producing life and is scheduled for the plugging and abandonment of wells from 2023. Following decommissioning, this nesting site would no longer be available, but the repurposing
of the platform, with the topside design developed to attract further nesting kittiwake, presents
an opportunity to preserve and increase this colony for many future breeding seasons ahead.

Fiona Goodfellow, Energean UK country Manager, commented: “Environmental, Social and Governance
(ESG) is at the heart of Energean operations and we are delighted to have partnered with like-minded
organisations on this project. It is particularly pleasing to work towards a positive and lasting legacy from our UKCS operations. The Wenlock platform has already established itself as a new seabird nesting site and
we are very excited to see plans progressing which may assist this valuable kittiwake population to prosper
and grow long into the future.”
