Wood has renewed its longstanding contract with Kellas Midstream to continue serving as operating partner (‘Duty Holder’), for the Central Area Transmission System (CATS) at Teesside in the United Kingdom.
Wood has operated the CATS processing terminal and the associated 404-kilometre pipeline transporting gas from the Central North Sea since 2015. Under the renewed contract, Wood will continue to manage all day-to-day operations, including maintenance, integrity management, emergency response and engineering services.
CATS remains a central part of the UK’s energy system. In 2025, the terminal delivered around eight billion standard cubic meters of gas to UK markets, meeting 10% of the country’s demand and accounting for roughly a quarter of total UK production.
Steve Nicol, Executive President for Operations at Wood, said:
'The safe, reliable operation of CATS is essential to the UK’s energy security. This contract renewal, secured through a competitive process, reflects confidence in our Duty Holder capabilities and the steady, assured approach our teams bring to managing critical national infrastructure. We value our long-term relationship with Kellas Midstream and look forward to continuing this work together.'
Nathan Morgan, Kellas Midstream CEO, said:
'Wood has been a trusted operating partner at CATS for over a decade, consistently demonstrating exceptional performance and a comprehensive understanding of this vital piece of UK energy infrastructure. Renewing this contract reflects the strength of our partnership, and our shared commitment to ensuring CATS runs safely, reliably and sustainably for many years to come.'
The contract will continue to be delivered by Wood’s team in Teesside, supported by Wood colleagues in Aberdeen and Glasgow.
Wood also serves as the operating partner for the Scottish Area Gas Evacuation (SAGE) system at St Fergus, Aberdeenshire, on behalf of Ancala Midstream, and supports several offshore and onshore assets for a UK operator.
