Near shore petroleum operations in Arctic sensitive environments call for detailed oil spill response planning, to ensure swift and proper response. This paper presents the results and conclusions from an extensive response planning project in the Norwegian sector of the Barents Sea.
Oil spill response for the operation was planned by a group comprising the operator, the Norwegian Clean Seas Association for Operating Companies, the Norwegian Coastal Authority, regional oil spill response groups and consultants. Drawing on these resources, the contents of the oil spill response plan were defined, as well as the need for training.
From the findings of this group, field surveys were made, identifying sensitive areas, access points and bays suited for oil containment. A baseline environmental survey was made to ascertain the current status of the environment.
Information from these surveys were integrated with national geographic databases on topography, bathymetry and shoreline sensitivity, and access to the integrated system is provided to all parts of the response organization through an Internet Map Server Interface.
The oil spill response plan is primarily web-based, and provides access to information on personnel, equipment, vessels, methods, training, exercises and organization. Also included are checklists for all functions, as well as standard forms for all relevant actions, from notification to shoreline cleanup operations.
In our experience, the combination of local knowledge and technical skills provided the basis for proper response planning. Georeferenced photos are essential in discussions of response options, and internet based response maps are an efficient way for different parties to get familiar with detailed response issues. Sharing information is required for proper functioning of oil spill response operations, and dealing with it in this manner has been a positive experience for the parties involved.
Introduction
The activity
Eni Norge AS (Eni) is the operator of Production License 229, located in the sub area "Finnmark West" in the southwestern part of the Barents Sea. The water depth in the license area is between 248 and 436 m. A map of the area, which also shows all the exploration/appraisal wells drilled in this part of the Barents Sea, is shown in Figures 1 and 2.
