4 Managing deepwater drilling risk We manage risk using a barrier philsphy. Strng and healthy barriers Risk Event We put barriers in place t Prevent accidents. This is ur tp pririty As an added precautin, we als put measures in place t Respnd t incidents Assurance and verificatin 3

5 Barrier failures at Deepwater Hrizn Each f the failures was analyzed resulting in: 26 drilling-specific recmmendatins 163 individual actins Changes t crprate structure and accuntabilities Enhanced capabilities t bth prevent and respnd Lessns shared with industry and gvernments 4

8 Testing the health f ur barriers thrugh assurance and verificatin We have a rigrus prcess f verificatin, assurance and audit t assure that the barriers are in place Examples f mnitring and testing the strength f ur barriers Risk Event Well cntrl cmpetency assessments Independent verificatin f BOP functin Technical Specialist review f znal islatin plans Assurance and verificatin Supprt and versight f cntractrs 7

12 Planning prcess 1. Identificatin f a range f planning scenaris that take int accunt the activity, barriers and failure mechanisms leading t an unplanned release f hydrcarbns 2. Ranking f these planning scenaris as a functin f severity and impact and selectin f a crss sectin f these planning scenaris 3. Identificatin f the apprpriate tactics (as a tiered scalable capability) t mitigate the effects f the release and grup these tactics int a respnse strategy 11

13 Planning scenaris Identificatin f a range f planning scenaris that take int accunt the activity, barriers and failure mechanisms leading t an unplanned release f hydrcarbns Planning Scenaris Transferring diesel fuel frm the supply vessel t the rig Refuelling the crew change helicpter n the rig Overfilling f the rig il drains system Failure f hydraulic pipeline r hses n the rig machinery Crude il release t the drill flr Subsea discnnect f the riser frm the BOP Lss f well cntrl (blw-ut) subsea Unexpected il in the riser during planned discnnect Fuel release frm a ditched helicpter Supply vessel cllisin with the rig causing supply vessel fuel tank leak Supply vessel cllisin with the rig causing the vessel t sink 12

14 Internatinal incident classificatin Ranking f these planning scenaris as a functin f severity and impact, and selectin f a crss sectin f these planning scenaris The respnse strategy shall be scalable and apprpriate fr the envirnmental cnditins and take int cnsideratin the health & safety f the respnders 13
