Purpose of the audit
The purpose the audit was to verify that StatoilHydro has management systems which reduce the risk of structural failure on ageing facilities, and that StatoilHydro has qualified solutions for handling technical integrity in loadbearing structures, so that the intention of the prevailing regulations is safeguarded.

The audit activity included StatoilHydro's follow-up of its supervisor responsibility vis-à-vis its suppliers.

Result of the audit
StatoilHydro has established a process for safeguarding technical integrity of loadbearing structures, and procedures for managing this process have been established.

We have discovered twelve nonconformities during the audit, and we have identified one area with potential for improvement.

The nonconformities and the potential improvement are related to the areas:

  • Follow-up of contractors / suppliers.

  • Organisation and safeguarding of responsibility, authority and competence.

  • Criteria for which structural incidents and damage will result in establishing emergency preparedness.
