Source: www.gulfoilandgas.com 2/16/2022, Location: Europe

The Petroleum Safety Authority Norway (PSA) has issued Rowan (Valaris) Norway Ltd (Rowan) with a notification of order, having identified serious breaches during an audit of electrical facilities, safety instrumented systems, technical safety and drilling-related systems on Rowan Viking. The audit was conducted between 8 and 12 November 2021.

Rowan holds the Acknowledgement of Compliance (AoC) for Rowan Viking. When the audit was carried out, the facility was on commission to Lundin Energy Norway AS on the Norwegian Continental Shelf.

Objective
The objective of the audit was to investigate how Rowan complies with regulatory requirements for electrical facilities, work in and operation of electrical facilities, safety instrumented systems, technical safety and drilling-related systems.

Result
The audit identified 15 regulatory non-conformities. These comprised:
- Non-conformity handling, manning and competence
- Ignition source control
- Overpressure protection
- Passive fire protection
- Firefighting
- Emergency power facility
- Emergency lighting
- Risk assessment of evacuation routes
- Work at height and falling object risk
- Electrical facilities and installations
- Electrotechnical system analyses
- Maintenance programme
- Deficient maintenance of BOP
- Work in and operation of electrical facilities
- Risk assessment of health hazards from electromagnetic fields

In addition, we observed two factors that we have chosen to categorise as improvement points. These concerned:
- Training and drills
- Competence and authority
- Follow-up of previous non-conformities

The audit also investigated how Rowan has handled a previous order and some previously identified non-conformities.

We found that Rowan has not addressed the following non-conformities in accordance with the regulations and with their feedback to us:
- Non-conformity concerning electrotechnical system analyses from chapter 5.1.8 of the report pursuant to the audit of electrical facilities and technical safety on Rowan Norway of 25 November 2019.
- Non-conformity concerning work in and operation of electrical facilities from chapter 5.1.9 of the report pursuant to the audit of electrical facilities and technical safety on Rowan Norway of 25 November 2019.
- Non-conformity concerning fire protection from chapter 5.1.1 of the report pursuant to the audit of Rowan Norway/Valaris’s management of emergency preparedness on Rowan Norway of 27 May 2020.

Order
The audit identified serious breaches of the regulations and we have therefore notified Rowan of the following order:
