Network for Barrier Management in Operation

24.05.2022

In April 2022, Safetec conducted the first physical network meeting for over two years, with the theme barrier management and functional safety/SIL in operation. Functional safety is the detection of a potentially dangerous condition that triggers devices or mechanisms, e.g. a shutdown valve, to prevent events or mitigate consequences. The agenda for the meeting consisted of three presentations followed by Q&A and discussion.

ORS gave a presentation regarding the interface between functional safety and barrier management. Functional safety is seen as a subpart of barrier management, constituting technical barrier elements. Ideally there should be consistency and a close relationship between barrier management, functional safety, and quantitative risk analysis (QRA). In practice these domains are managed based on different standards and different disciplines, resulting in a need for collaboration and flow of information between the domains to succeed. It was also noted that while barrier management has matured well for topside, it is still a need for further development for the subsea part of operation.

Lundin Norway and Neptune Energy both presented how they were to follow up SIL in operation by active status monitoring. Lundin focused on the use of sensors for retrieving live data, and to apply models to combine different data inputs into an aggregated visualised status. The purpose is to reveal errors before incidents by automatic generation of work orders, to reveal root causes to avoid similar errors, and to focus on ‘bad actors’. Neptune presented SOFUS 2.0, which is a software tool developed by Safetec for analysing and visualising testdata as part of SIL in operation. The purpose is to provide high quality transparent and traceable decision support.

It’s been ten years since the Petroleum Safety Authorities published their first version of Barrier Memorandum. Since 2012 it has been revised two times, first in 2013, and then with the current 2017-version.  While the central principles for barrier management are still valid, the interpretation and application of barrier management are still maturing in the industry. As a leading risk management consultancy, Safetec has worked with barrier management for several companies since 2012 until today.

Network for barrier management in operation was started in 2019 with the intention to act as a professional network for oil and gas producing companies operating on the Norwegian Continental Shelf and onshore in Norway alongside consultancy companies in the field of risk and barrier management. Safetec constitutes the secretariat of the network, with the responsibility of planning and conducting network meetings, writing summaries of meetings, and maintaining a web-based member forum. Current members are the operators ConocoPhillips, Equinor, Gassco, Lundin Norway, Neptune Energy, OKEA, OMV, Repsol, Vår Energi, Wintershall Dea, and the consultancies DNV, ORS, Safetec, and Vysus Group.

The next network meeting will take place in November 2022.
