Repsol Sinopec Resources UK has embarked on a two-phase project aimed at extending the life of the Claymore platform, one of the oldest in the North Sea, to beyond 2030, by which time it will be 54 years old.

With an initial investment worth £45 million ($62 million), the North Sea-focused joint venture has started work to reactivate the platform's drilling package - last used in 2011 – and will then make a start on three well workovers.
