BNOC was responsible for a extremely small part of North Sea development you make sound like whole of UK oil and gas was under national control, are you from the UK if you are where are you getting your information from. BNOC was launched in 1975 under the Petroleum & Submarine Pipe-lines Act 1975 and mostly concerned with getting adequate supplies of oil onshore to lessen the UK dependence on Mid_East oil supplies of which at the time looked a bit shaky.Quote from Misthos:Remember the UK before the global credit bubble and before Lady Thatcher privatized efforts to extract North Sea Oil? It was a mess.
Some oil economists reckon that if BNOC had been kept under national control and assumed responsibility for pipeline and landfall infrastructure this would have created greater shareholder value in the exploitation companies.
BNOC was sold off between 1982-85 thereafter BP bought it in 1988
