Result of the audit

Gassco, with Statoil as technical service operator, appears to have satisfactory management and control of the takeover and start-up activities in TOP.

However, we pointed out a risk relating to extensive use of scaffolding at the NGL facility, which is now pressurised and in trial operation. This was discussed especially in the debriefing meeting and we sent a separate letter regarding the matter immediately after the audit.

A reply from Gassco/Statoil has been received and is considered satisfactory.
