Uncertainty in pore pressure estimation continues to contribute to well control incidents on the Norwegian continental shelf. A new report highlights how improved methodologies, technology and clearer communication can help reduce this risk.

The Norwegian Ocean Industry Authority (Havtil) has carried out a preliminary project to strengthen the knowledge base regarding local conditions in the sea areas that have been opened for seabed-mineral exploration. The report describes key environmental conditions and uncertainties that could affect safety, emergency preparedness and the working environment in any future mineral activities.

Havtil has conducted a series of audits focused on driller’s cabins on the Norwegian continental shelf. The audits reveal a number of challenges in respect of the follow-up of alarm systems, working environment assessments and the use of available data.

The Norwegian Ocean Industry Authority (Havtil) has commissioned a new report that provides an updated basis of experience for assessing the integrity of welded and mechanical connectors in pipelines and subsea facilities. The report shows how right choices early in the design phase are crucial for safe and responsible operations throughout the entire service life.

On commission from Havtil, Safetec has prepared a report that presents a way to keep track of operational barrier elements. The report also describes how competence can be strengthened among operational personnel concerning barrier management relating to maritime incidents.

Havtil has undertaken knowledge gathering on how creeping shale can be qualified and used as a well barrier element for permanent well plugging.

Multiple incidents have revealed weaknesses in using cemented shoe track as a well barrier. New report compiles industry experiences and proposes measures for improved verification and safer practices.

SINTEF has investigated whether remotely operated underwater vehicles controlled from control rooms onshore alter the risk picture for subsea installations.

The Norwegian Ocean Industry Authority (Havtil) has surveyed how the onshore facilities follow up emergency shutdown systems (ESD).
