It was worried that similar incidents could occur as seabed subsidence continued. That prompted it to give the licensees in production licence 018 notice of an order on 8 October:
”The above-mentioned conditions on 2/4 T do not accord with the minimum requirements in the regulations for the safety of people, the environment and material assets.
”Continued modifications on 2/4 T will be insufficient to compensate for the negative trend in the level of risk on the facility …
”Persistent subsidence could also contribute to a continuous worsening in the risk picture. Consideration for the safety of people, the environment and material assets requires a permanent cessation of processing and transport activities on 2/4 T.
”Given the expected development of the risk level on the facility, the NPD concludes until further notice that the above-mentioned activity on 2/4 T must cease permanently from the winter season of 1995-96 at the latest.”
Phillips Norway CEO Knut Åm claimed that the tank was in better condition than ever. But this letter was a serious warning to the company as operator of Ekofisk, and eventually triggered plans for the Ekofisk II development.[REMOVE]Fotnote: Lerøen, Bjørn Vidar, 1001 brønn.
