Subsea technology occupies an important place in present-day petroleum technology and its use is expected to increase in future developments. Experience and the results of RNNP (risk level in the Norwegian petroleum activity) analyses in recent years have shown that accident prevention in petroleum activities on the seabed is an area that warrants more attention. The companies must work on continuous improvement to safety and ensure the existence of measures to prevent and mitigate the risk of accidents under water. They must also have in place the necessary barriers for detecting, limiting and stopping undesirable incidents and accidents.
The objective of the meetings was to clarify whether maintenance practice for subsea facilities was being undertaken prudently. This entails giving the operators adequate oversight of the status and trends in status over time and helping ensure that information is used to prevent accidents and promote continuous improvement.
We focused particular attention on the maintenance of barriers for subsea facilities, and collected knowledge about and experience of this issue.
We placed special emphasis on processes for:
Prudent maintenance practice also depends on management across the interface between operators and contractors. For this reason, we held meetings with both operators and contractors – the latter within equipment supply and/or the performance of maintenance.
Topics for the meetings
We asked the operators to give a presentation covering the following topics:
The contractors were asked to cover the following topics:
The results are summarised in the attached report.
