UK Regulator Trying To Block Release of Shell North Sea Documents

The UK’s oil and gas regulator is coming under fire from environmental groups for using lawyers to try to prevent the publication of five key documents relating to the environmental impact of Shell’s activities in the North Sea. From a report: At a hearing in December, a legal representative for the North Sea Transition Authority (NSTA) is expected to argue against the publication of documents that contain details about the risk of pollution as a result of decommissioning the Brent oilfield, which was operated by Shell for more than 40 years. It says it opposes publication “on a matter of process basis.” Shell has applied for an exemption from international rules that require all infrastructure to be removed from the field and the UK government is deciding whether it will allow the oil company to leave the 170-metre-high oil platform legs in place for the three platforms known as Bravo, Charlie and Delta.

A total of 64 concrete storage cells are contained in the leg structures, 42 of which have previously been used for oil storage and separation. Most of the cells are the size of seven Olympic swimming pools, and collectively still contain an estimated 72,000 tonnes of contaminated sediment and 638,000 cubic metres of oily water. Environmental groups believe the documents held by the NSTA would reveal new information about long-term environmental dangers that is relevant to other North Sea oil developments, including Equinor’s plans to develop Rosebank, the UK’s largest untapped field.
