Petrofac has won a decommissioning contract worth around £12.2m with Tullow Oil.
The energy services firm will act as well operator for the Thames decommissioning project in the southern North Sea.
As well operator, Petrofac will be responsible for plugging and abandoning three subsea wells on the project, including planning, management of sub-contractors and provision of a jack-up rig.
Petrofac said the award comes following other successful P&A campaigns for Tullow in 2016 and 2018, shutting down seven wells and making savings of more than £4.9m.
Alex Macdonald, managing director of well engineering for Petrofac Engineering and Production Services, said: “We are delighted to further strengthen our relationship with Tullow Oil as it takes the next step in its Thames Decommissioning project.
“At the end of the asset lifecycle, the focus on cost and schedule remains as important as ever.
“This award is testament to the approach we take to optimise operations through new decommissioning techniques and maximise collaboration across the supply chain in order to drive efficiency.”
The Thames platform is located around 44miles north-east of the nearest landfall of Winterton-on-Sea on the eastern coast of England.
