The audit was conducted between 30 September and 4 October 2019.
The objective of the audit was to examine how Equinor ensures compliance with the authorities’ requirements relating to technical safety, process safety and electrical facilities, and how barrier management contributes to robust solutions at Troll B.
We identified nine regulatory non-conformities. These concerned:
- Deficient non-conformity handling
- Inadequate prioritisation of improvements to safety-critical equipment
- Deficiencies in equipment labelling
- Missing documentation of selectivity in UPS installation
- Missing warning signage
- Inadequate knowledge of the condition of technical barrier elements
- Inadequate overview of decision-making criteria and status of weaknesses in safety systems
- Insufficient capacity of emergency power batteries for emergency lighting
- Defects in automatic actions in the event of gas detection
We also observed five improvement points. These comprised:
- Inadequate incident follow-up
- Deficiencies in operating and control equipment for motors and other consumers
- Deficiencies in passive fire protection of hydrocarbon-carrying equipment
- Inadequate illumination in emergency hospital
- Deficiencies in documentation
What happens now?
We have asked Equinor to report on how the non-conformities will be addressed. We have also asked the company for its assessment of the improvement points we observed. The deadline for reporting back to us is set at 16 January 2020.
