PSA: Audit of planning and execution of drilling and well operations
Tuesday, Dec 12, 2017
PSA has carried out an audit of Wintershall, Odfjell (drilling contractor) and relevant drilling and well service contractors' planning and execution of drilling and well activities on the Maria field using the Deepsea Stavanger drilling rig.


The objective of the audit was to verify that Wintershall and Odfjell, together with the service companies, are meeting the regulatory requirements for planning and execution of drilling and well operations.

The audit emphasised how decision support, criteria and processes, including risk assessments and analyses, have been established and implemented in order to ensure well control and safe, robust operations.


One non-conformity was identified in connection with the notifying and reporting of incidents to the PSA.

In addition, two improvement points were identified in connection with:

  • Learning from incidents
  • Categorisation of safety-critical equipment
Wintershall and Odfjell have been given a deadline of 5 January 2018 to report on how the non-conformity and improvement points will be addressed.
