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.

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.

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.
