Background for the audit
The PSA is to set standards and follow up to ensure that the players in the petroleum activities maintain high standards of health, safety and environment and thereby contribute to creating the greatest possible values for society.
This follow-up shall be system-oriented and risk-based, and it shall come in addition to the follow-up the industry itself is responsible for.
Chapter 4.12.2 of Storting White Paper No. 7 (2001-2002) on health, environment and safety in the petroleum activities states in part the following regarding management of maintenance:
"The authorities believe it is necessary to further develop management models for maintenance in cooperation with the industry to ensure a joint commitment towards strengthening the quality of maintenance in the petroleum activities, through measures such as further development of methods and technologies, enhancing expertise and research."
Chapter 5.4 of Storting White Paper No. 12 (2005-2006) on health, environment and safety in the petroleum activities points out that deficient maintenance can increase the risk of major accidents, injuries and accidents, and the White Paper refers to a fairly comprehensive review of audit reports that reveals a relatively high incidence of regulatory nonconformities, including deficiencies in prioritizing maintenance, assessment of critical factors, follow-up of temporary equipment, unsatisfactory documentation and outstanding maintenance of critical safety equipment. In some cases, competence in maintenance management was also insufficient.
The relevant requirement are laid down in particular in the Activities Regulations, Chapter IX relating to maintenance, Sections 42-46 and in Section 13 of the Management Regulations relating to general analysis requirements.
Purpose of the audit
The purpose of the audit was to check whether Statoil fulfils the maintenance requirements, particularly as regards classification of systems and equipment, and roles and responsibilities in this context. We also wanted to verify compliance with classification data throughout all phases of the lifetime.
Result of the audit
The results are based on a presentation of elements in Statoil's management systems (as specified by us) and conversations with selected personnel, with subsequent verification of governing documents and procedures and programs for executing maintenance on Statoil's facilities in Norway.
It is our assessment that Statoil does not fulfill the regulatory requirements for classification of systems and equipment, and for the use of this classification.
With the current status of the classification, it is difficult to formulate a correct picture of the actual risk as a basis for making decisions for maintenance purposes, and thus also of the extent of the maintenance needs, and the resources the maintenance will require.
Our observations are characterized as nonconformities, ref. the categorization in Chapter 5, and they are grouped into the following main areas:
