VetcoGray Umbilical Monitoring Device (UMD)
Our VetcoGray (UMD) is specifically designed for subsea umbilicals tied back to floating systems. It connects to the closest point between the center tap of the subsea isolation transformer and the protective conductor.
With its combination of sophisticated hardware and advanced software algorithms, the UMD can detect a wide range of leakage conditions in umbilical. The device's high sensitivity is achieved through intelligent signal amplification, a precise online calibration service and DC offset detection and elimination.
Features & Benefits
Flexible integration. The UMD features a system-friendly measuring signal that is controlled by pulse-width modulation (PWM), the signal frequency and pulse width can be varied to maximize application flexibility.
Design & performance. The UMD performs line insulation monitoring (LIM) to identify breakdowns in insulation resistance (IR). It can actively function while connected to umbilicals powered up to 1,000 V AC at 50-60 Hz.
Precise measurement capabilities. By measuring both insulation resistance and leakage capacitance, UMD accurately calculates the exact condition of the umbilical system.
