Fears of fire and environmental disaster as company repeatedly misses UK deadlines to decommission sites

The North Sea’s biggest oil and gas infrastructure company is risking fires and environmental disasters, experts have warned, as documents reveal it is failing to plug its ageing oil wells in time and is missing decommissioning deadlines by up to a decade.

Last year, the fossil fuel firm Perenco faced controversy after an oil spill from its Poole Harbour operations polluted the Dorset site, which is internationally recognised for its ecological importance. The RSPB reported oiled birds in the water at the largest natural harbour in Europe, which is one of the most heavily protected areas in the UK. Perenco promised it would never happen again and committed to pay for the damage caused.
