On 5 January 2011, the Petroleum Safety Authority Norway, PSA, and the Civil Aviation Authority, CAA, conducted an audit of BP Norway’s Valhall PH directed towards emergency preparedness management and helicopter deck operations.
The audit was a supplement to the previous technical audit of Valhall PH, and included emergency preparedness analyses, emergency preparedness plans and organisation, as well as a review of CAA report 2010F505.
A helicopter trip to the Valhall field is longer than to any other field in the Norwegian sector. In 2010 and 2011 additional accommodation is present, and the manning level higher in order to execute a lot of planned activities such as the Valhall redevelopment project (VRD). Regular manning levels during these two years will be between 400 and 600 people.
The field gets supplies at least twice a week. Both provisions and equipment are transported by boat from the warehouse and supply base in Tananger.
Valhall has good neighbours and co-operators with the adjacent platforms – particularly Ekofisk and Gyda/Ula – concerning tele-communications, boat and helicopter traffic.
The activity at Valhall is very high and a flotel rig is at the field until summer of 2011 to accommodate extra personnel working with modifications and preparing forstart up of the new platform. This work goes on whilst there is full operation on the seven platforms that makes up the Valhall field. Valhall is under steady development and several additional projects are also under consideration.
The Valhall complex consists of five separate steel platforms for quarters, drilling, wellheads, production and water injection respectively. The platforms are bridge-connected. In addition the field has two unmanned flank platforms, one in the south and one in the north, both around 6 kilometers from the field center. Valhall is also the owner of the 2/4 G-platform installed in 1982, located at Ekofisk and operated by Conoco Phillips. The platform was taken out of service as part of Ekofisk II in 1998.
In 2010, the PSA and CAA carried out audits of the living quarters module, process module and helicopter deck at the shipyards.
At the time the governing documentation was not complete, and the CAA identified a few remaining items in connection with helicopter operations.
The objective of the audit was to verify that Valhall PH manages its activity in accordance with the regulations. This includes e.g. analyses, plans, organisation and procedures.
Based on the audit, Valhall PH shows good solutions and the general impression is of a robust emergency preparedness management based on best practice on the Valhall field. We did not identify any nonconformities or improvement items during the audit.
