Audit of Statoil – use of Haven on the Johan Sverdrup field.

The PSA has carried out an audit of Statoil and its follow-up of the Haven mobile facility for use on the Johan Sverdrup field.


Haven is a jack-up facility, certified for use in water up to 83 metres deep. Statoil wishes to use it in deeper water on the Johan Sverdrup field. This entails a considerable lengthening of the legs, and the requirement for a different type of foundation (suction anchors). Haven is to be deployed on the Johan Sverdrup field from 2018.

On 1 and 2 February 2017, we carried out an audit of Statoil in connection with the extension of Haven's legs, new foundations and site-specific analyses of the load-bearing structures.

The objective of the audit was to perform spot checks of whether the project engineering of the jack-up facility complied with applicable regulations.

No non-conformities with the regulations were detected during this audit.

One improvement point was identified, concerning the use of Statoil's FAR values as acceptance criteria for risks.
