Audit of HSE management in the drilling and well area on Valhall

Audit: From 5 November 2008 to 12 February 2009 the Petroleum Safety Authority Norway (PSA) conducted an audit of HSE management in the drilling and well areas on the Valhall field, which is operated by BP Norge AS (BP). Our impression is that there is a good relationship between the operator, drilling contractor and well service company in terms of cooperation, but we identified two non-conformities and four items with improvement potential.


The audit started with a kick-off meeting in the land organisation on 5 November 2008 at BP’s offices at Forus with representatives from the operating company and the well service company.

The audit continued on 26 and 27 November 2008 with interviews of relevant personnel in the land organisation and a guided tour of BP’s offices for integrated operations. 

From 9 to 12 February 2009, verifications and interviews were conducted with relevant personnel on the Valhall facilities.

Talks were held with the safety delegates and main safety delegate on Valhall.

Background for the audit
In 2008 the PSA’s main priorities included: ”Technical and operational integrity for lifetime extensions” and ”Integrated operations”.

Valhall

On the basis of the extended lifetime for Valhall DP, it was necessary to verify conditions surrounding the activities on DP and further HSE plans in connection with safeguarding of well integrity.
 
There was also a need to verify technical and operational conditions in the well and drilling areas on WP and IP.

BP was one of the first companies that actively employed integrated operations during drilling activities. We wanted to see how this concept had developed and what the plans for the future are within this area.

One of our objectives during the audit was to verify that measures implemented in 2006 on Valhall IP have had the desired effect.

Purpose of the audit
The objective of this task was to verify the company’s compliance with relevant HSE requirements in the drilling and well areas on the Valhall facilities, with emphasis on DP.

The following topics related to HSE management were part of the audit:

Result of the audit
