The Petroleum Safety Authority Norway (PSA) conducted an audit of operation, maintenance and inspection of pipelines and subsea facilities at ExxonMobil (EM) on 19 May 2009.
The audit was carried out as a meeting and covered management systems, technical condition inspection, risk-based inspection and transfer of experience.
Background of the audit
The audit is related to an issue which is particularly prioritised by the PSA in 2009 – namely to assess how the players ensure that prudent safety levels are maintained on the facilities and systems which are planned for use beyond their original lifetimes.
Comparable audits of other operators of pipelines on the Norwegian Shelf will also be carried out during the course of this year.
Purpose of the audit
The primary purpose of this the audit is to assess EM's compliance with the regulatory requirements regarding health, environment and safety as regards operation, maintenance and inspection of pipelines and subsea facilities.
Furthermore, the goal of this the audit is that it may provide a picture of the condition to the pipelines and subsea facilities where EM is the responsible operator.
Result of the audit
During the meeting EM presented its management system for pipeline integrity – Pipeline Integrity Manual. Our impression is that this is a system which is maintained and used to manage operation, inspection and maintenance of pipelines and subsea facilities.
The audit did not identify any non-conformities in relation to the regulations.
One potential improvement item was identified: Clarification of the division of responsibility between EM and StatoilHydro (SH) for the operation of the Sigyn field.
