Phillips submitted a plan for development and operation (PDO) of the Ekofisk II project to the government. It was expected to cost NOK 20 billion in 1994 value.

The proposal was to build two new facilities – wellhead platform Ekofisk 2/4 X and process centre 2/4 J – with the capacity to handle the plateau production envisaged from 1998.

This meant these installations were designed to deal with a daily output of 220 000 barrels of oil and 750 million cubic feet of gas.

That contrasted with 260 000 barrels and a billion cubic feet for the former facilities. But a number of the small fields in the Greater Ekofisk Area were expected to cease production.

More about history

What caused the Alexander L. Kielland-accident?

The commission of inquiry into the Alexander L Kielland accident submitted its findings on 6 April 1981. On 2 April 1982, the Ministry of Local Government and Labour followed up with a White Paper.

The Bravo Blow out

The “abandon platform” alarm sounded on Ekofisk 2/4 B – the Bravo installation – at 22.00 on Friday 22 April 1977. An uncontrolled escape of oil and gas had begun in well B-14. Large quantities of oil and gas spurted five-six metres into the air before falling into the sea. What should not have happened had occurred. The question was how this could be possible.
