Background for the audit
A key prioritization in our HSE follow-up is to ensure that the players monitor the technical condition of the facilities. In this context, good follow-up in the design phase is important in order to reveal any potential weaknesses that may have consequences in the operations phase.
In connection with our consideration of the Plan for Development and Operation (PDO) of the Tyrihans field, we targeted several areas for follow-up in our ongoing work with this development.
The project represents new challenges linked to pipeline design and choice of materials. It also contains many interfaces and management of the activities in the design phase is challenging.
We have previously conducted an audit of how Statoil managed fabrication of the production pipeline to Tyrihans (link).
Purpose of the audit
The purpose of the audit was to follow up and ensure that the engineering is planned and executed according to applicable regulations and recognized standards.
Another objective was to verify the operator's system for following up suppliers, and check that the management systems ensure transfer of experience to and from the project.
Result of the audit
Statoil has established a management system for design of pipelines to Tyrihans, and this management system has been implemented in the project.
No nonconformities were identified during the audit, but we have found six areas where there is potential for improvement.
These areas are management of uncertainty, transfer of experience, handling of nonconformities in Statoil, internal audits for Rambøll, missing/deficient job descriptions for several key positions and lack of defined processes in governing documentation.
