WinCatt

WinCatt is a software tool which interacts with external control hardware to provide real time monitoring and control of tubular connection power tong make-up. The graphical user interface and logical software structure combined with powerful control, data acquisition and presentation capabilities enable the user to easily specify make-up parameters, control the make-up process and evaluate quality.

WinCatt was developed with an emphasis on the user's needs for reliability, accuracy, and ease of use.

Features:

  • monitors torque, turns, and rotational speed during make-up
  • controls speed during make-up (optional)
  • controls based on either final torque or final turns
  • includes calibration management system
  • includes automatic "Start Recording" & "Dump Valve Release"
  • includes automatic descriptive comments with optional over-ride
  • available with optional pressure test system

Analysis:

  • analyzes make-up to determine: conformance to manufacturer's specification shouldering point for premium connections shouldering time, delta torque, delta turns
  • reviews results from previous make-ups

Safety:

  • limit torque to user specifies maximum during idle time

Reporting:

  • job description
  • summary reports of make-up results
  • statistical analysis
  • real time or post job make-up plots

Specifications:

Sampling Frequency User defined from 1 - 8000 Hz 500 Hz recommended
Recording Frequency Based on combination of delta torque and user defined delta time
Calibration Management Choice of calculated calibration based on load cell manufacturer specifications or local calibration based on user force standard. Shunt calibration with automatic "drift" tracking.
Response time Electronics < .5 ms
Hydraulics - dependent on dump valve - typically 10 - 30 ms
Final torque Average = optimum torque +/- 1%
Standard Deviation < 2% under normal operating conditions
Operating temperature Computer, 5 - 50°C (40 - 122°F)
Junction box, minus 30 - 80°C (minus 22 -180°F)
Torque accuracy max error (% of full scale) = sqrt[Local force standard error2 + arm length error2 + 0.152]
Typically less than 1%
Turns accuracy max error = +/-one pulse of turns counter
Pressure accuracy max error (% of F.S.) = sqrt[pressure standard error2 + 0.152]
Typically less than 1%
