Support BOP Test Station Improvements

Aiken Completed the following scope:

  • INVESTIGATE A 150 HP MOTOR STARTUP UNDER LOAD ISSUE. The 480V connections were not properly insulated so wire conductors arc’ed against the motor starter panel. Also, the VFD was undersized. Proper insulation was applied and the VFDs were replaced with correctly specified VFDs.
  • CALIBRATE 2 REGULATOR ASSEMBLIES. A 4-20 mA signal was scaled by 83% so an electric-pneumatic regulator would supply the design basis 0-100 psi range instead of the shop’s 0-120 psi range to a pneumatic-hydraulic regulator.
  • INTERFACE GAUMER PROCESS ELECTRICAL PANELS WHICH POWER HEAT GENERATION RODS WITH NATIONAL INSTRUMENTS CONTROLS HARDWARE. Schematics were reviewed and wires were terminated on a 24V coil of a relay which enabled the heater panel. Also 4-20 mA control wires were installed between the heater controllers and power distribution panel.
  • CREATE A CONTROLS & INSTRUMENTATION INVENTORY SPREADSHEET. Key parameters of controls hardware per test station were documented & summarized. Each Program, location, PLC, module, signal type, range, and device were documented in several spreadsheets.
  • COMPILE EXISTING TEST STATION P&IDS AND PROGRAMS. Original diagrams for the controls hardware which had been modified over the years were compiled since they were not available in the expected database.
  • TEST RUN THE NEW ACCUMULATOR STAND
  • MODIFY THE DAQ BOX PROGRAM FOR A DIFFERENT CHASSIS & MONITOR SIZE. This was challenging because the labview project was very complex & included ~150 VIs. A longer distance between PLC and computer was desired so the USB-type PLC was replaced with a RJ45-type PLC. Instances of each I/O variable were replaced in the program to reference the new PLC & the window properties were changed. Additionally, the code revision had to be compiled with the same version (from 2013) of the development program labview to work. A newer version such as labVIEW  2015 would not work.
  • REVIEW & IMPROVE THE TEMPERATURE CHAMBER P&ID AND DATABOOK
  • SUMMARIZE TEST SIGNAL HISTORY
  • COMMISSION NEW PROGRAM & NEW EQUIPMENT
