The objective of this audit was to verify that regulatory requirements relevant for the ongoing improvement works were being complied with.

Result

No non-conformities were identified.

An improvement point was identified connected with the investigation of causes of corrosion.

Gasco AS has been given a deadline of 26 November 2015 to report on how the improvement point will be dealt with.

Non-conformity:

Entails that a condition is assessed as not complying with a regulatory requirement.

Improvement point:

Entails that we have identified a deficiency or weakness, without there being sufficient grounds for determining a breach of regulatory requirements.

The Kårstø processing facility was opened in 1985 to receive gas from the northern North Sea. The plant has been subsequently expanded and modified several times. Due to general aging and in order to receive heavier condensate from Gudrun, there was an ongoing project during the period 2012-2014 to upgrade the receiving terminal at Kårstø.

It has also been necessary to improve the T300 gas pipeline system with valves in the downstream condensate stabilisers due to internal corrosion. This has been monitored over several years.

In 2014, lifetime assessments were made of the T300 system, which concluded that improvements were necessary.  A specific project has now been initiated by TSP Statoil on commission from Gassco AS.
