The audit was conducted from 10 to 11 March 2020.

Objective

The objective of the audit was to verify that Esso’s management of the maintenance of Slagentangen, including follow-up thereof and any ongoing changes that affect such management, comply with the authorities’ and the company’s requirements. We also wanted to check that work on improving maintenance management is ensuring that important contributors to HSE risk and uncertainty are identified and followed up.

No non-conformities or improvement points were identified during this audit.

Follow-up of previous audits

In an audit of Esso and Slagentangen in 2019, we identified a non-conformity relating to the planning of maintenance.

We wanted to verify how Esso has addressed this non-conformity to date.

Our audit shows that the improvement work is well underway and the process has been described, but delayed somewhat relative to Esso’s feedback to us.
