From 29 March to 7 April 2017, we carried out an audit of Statoil focused on how it safeguards the planning and execution of drilling and well operations on Visund A. The objective was to verify that Statoil and its contractors in the Visund organisation meet the regulatory requirements.
The audit identified three regulatory non-conformities, concerning:
- The diverter system in the BOP stack
- Pressure control equipment
- The company's own follow-up and assessment of maintenance, maintenance effectiveness and maintenance history in the drilling facility
In addition, five improvement points were identified in connection with:
- Certified well-control competence for individual job positions
- Roles and requirements for competence concerning risk assessments
- Identification and description of safety-critical tasks
- Information for the safety delegate service
- Information dissemination and employee participation in connection with change processes
We have asked Statoil to report on how the non-conformities will be dealt with. The deadline for this has been set at 25 September 2017.
Visund is a field located in the northern part of the North Sea, northeast of the Gullfaks field. The water depth is 335 metres. Visund was discovered in 1986, and the plan for development and operation (PDO) was approved in 1996. The field is developed with a semi-submersible, integrated accommodation, drilling and processing facility (Visund A) and a subsea facility in the northern part of the field. Production started in 1999.
