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.

9
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.

12
Relief Valve RV-1919
  • The intended design pressure setting was 740 psig
    which was then lowered to 650 psig.

13
Relief Valve RV-1919
  • Fisher-Rosemount misinterpreted specification
    sheets and provided a 100 psig set point.

14
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.

15
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.

17
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.

18
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.

19
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.

20
Bayview Operations
  • After commencing operations at the Bayview
    products terminal, Olympic management did not
    adequately address operational issues.

21
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.

22
Bayview Operations
  • Olympic did not exercise effective management
    oversight of the construction and activation of
    the Bayview products terminal.

23
Federal Regulations
  • Require annual testing to determine that relief
    valves are functioning properly, in good
    mechanical condition, and have adequate capacity
    and reliability.

24
Federal Regulations
  • Regulations provide insufficient guidance to
    ensure that test protocols and procedures will
    effectively indicate relief valve or pilot
    control malfunctions.

25
Federal Regulations
  • Since Bayview was a new facility, OPS regulations
    also required that RV-1919 be tested under
    conditions approximating actual operations.

26
Federal Regulations
  • Regulations for new installations do not provide
    adequate guidance to ensure that relief valves
    are tested under conditions approximating actual
    operations.
