9 ALASKA FUEL TRANSFER Operating Conditions and Procedures Preparation Spill Response Equipment Booming Equipment Planning Termination Completion Declaration of Inspection

10 Planning for Fuel Transfer The transfer operation should be planned and agreed in writing between the two (or three) parties and, should include information on the following: 1. Quantity and type of each fuel to be transferred, 2. Flow rates, 3. Normal stopping and emergency shutdown procedures, 4. Emergency and spill containment procedures, 5. Local or government rules that may apply (MMS for EPW contracted vessel), 6. Material Safety Data Sheet, 7. Coordination of plans for cargo hose connection, monitoring, draining and disconnection. 8. Declaration of Inspection is signed USCG requirement 9. Shell Pre Transfer Checklists are Completed 10. Due regard to vessel stability

12 Preparations : Spill Response

13 Planning for Fuel Transfer (2)

14 DURING THE TRANSFER Fuel transfers should be immediately stopped : A leaking pipe or hose is discovered, If the containment boom is deployed, ice hazards may require releasing the boom, preventing effective immediate spill containment, Vessel moorings fail or are not adequately securing the vessels, Shifting of the transfer vessels locations due to wind or current that cause the containment boom to be compromised, Increase in other safety or environmental risk factors that become elevated to an unsafe level

15 COMPLETION OF TRANSFER After completion of cargo transfer : 1. Hoses drained into the agreed upon tank, 2. Hoses disconnected and securely blanked, 3. Cargo manifolds should be securely blanked

16 VESSEL INSPECTION All vessels used by Shell are required to be Inspected and Approved Assurance that vessels adhere to International, Local and Shell Standards Condition and management of the vessels are checked Includes : Fuel Transfer Procedures checked
