The Kashagan field is operated by an international consortium of 7 major oil companies under the North Caspian Sea Production Sharing Agreement.  The field is exposed to severe offshore elements, with temperatures rising to 40 degrees in the summer and falling to -35 degrees in winter, and produces a light oil with a high gas-oil ratio and a very high hydrogen sulphide (H2S) content.  H2S is extremely toxic and potential exposure puts personnel working at the field at high risk.

The consortium looked for a solution to accurately quantify risk.  Despite the availability of ‘off-the shelf’ industry solutions for Quantitative Risk Assessment (QRA), the consortium felt these packages lacked the transparency and flexibility required to accurately assess the risk for their specific environment. As a result the consortium went to tender, which Risktec Solutions won with the help of Tessella by showing that as a team they were able to design and develop a bespoke QRA solution meeting their specific requirements. This solution would provide the consortium with a cost effective, flexible and accurate alternative. Risktec Solutions chose Tessella for their strengths in technical modelling and professional software development.
