  1. Olympic’s management of the construction and commissioning of the Bayview Products Terminal.

  2. Bayview Products Terminal

  3. X X

  4. Control Valve CV-1904 • Inlet control valves had an extended piston stop set. • Outlet control valves did not have an extended piston stop set to prevent pumping against a closed valve.

  5. Control Valve CV-1904 • The stop setting was not reached so it did not play a role in the accident. • Demonstrates ineffective management oversight of the terminal construction.

  6. RV-1919 Bayview Products Terminal

  7. Set screw Relief Valve Pilot

  8. Relief Valve RV-1919 • The intended design pressure setting was 740 psig which was then lowered to 650 psig.

  9. Relief Valve RV-1919 • Fisher-Rosemount misinterpreted specification sheets and provided a 100 psig set point.

  10. Relief Valve RV-1919 • Fisher-Rosemount clearly indicated the 100 psig setting in documentation and on the pilot. • Olympic and/or Jacobs should have noticed the discrepancy.

  11. Relief Valve RV-1919 • No testing under conditions approximating actual operations was conducted prior to start up. • Olympic did not discover that RV-1919 was not set correctly until it started operations at Bayview.

  12. Ends of Compressed Spring

  13. Relief Valve RV-1919 • Inlet block valve closed 35 times due to high pressure in Bayview. • In May 1999, Olympic reduced the set point of RV-1919 to 650 psig.

  14. Relief Valve RV-1919 • Inlet block valve closed 6 more times before the accident. • Olympic did not make adequate efforts to investigate the block valve closings.

  15. Relief Valve RV-1919 • Olympic should have investigated the failure of RV-1919 to operate consistently and taken measures to correct the condition that may have prevented the pressure surge that ruptured the pipeline.

  16. Bayview Operations • After commencing operations at the Bayview products terminal, Olympic management did not adequately address operational issues.

  17. Bayview Operations • Did not test RV-1919 under actual operating conditions. • Did not correct valve configurations. • Did not adequately investigate block valve closings. • Did not adequately address operational issues.

  18. Bayview Operations • Olympic did not exercise effective management oversight of the construction and activation of the Bayview products terminal.

  19. Federal Regulations • Require annual testing to determine that relief valves are functioning properly, in good mechanical condition, and have adequate capacity and reliability.

  20. Federal Regulations • Regulations provide insufficient guidance to ensure that test protocols and procedures will effectively indicate relief valve or pilot control malfunctions.

  21. Federal Regulations • Since Bayview was a new facility, OPS regulations also required that RV-1919 be tested under conditions approximating actual operations.

  22. Federal Regulations • Regulations for new installations do not provide adequate guidance to ensure that relief valves are tested under conditions approximating actual operations.
