ClampOn Non-intrusive sensors for Subsea Vibration Monitoring.
Vibrations always start at very high frequencies and change to lower frequencies as the conditions develop. The ClampOn DSP Vibration Monitor is an ideal instrument to monitor three directional vibrations on structures and pipelines with either high frequency shear waves or low frequencies. The Vibration Monitor is designed with a broadband frequency from 0 Hz to 1000 Hz in terms of 3D vibration, at the same time as ultrasound noise can be monitored up to several hundred kHz. Solutions are available for early detection of vibrations in objects such as:
• Flow lines, jumpers
• Pumps, rotary machinery
• Subsea structures
The ClampOn Subsea 3D Vibration Monitor is a non-intrusive vibration and noise monitoring system. The system allows monitoring of vibration and acoustic noise signatures across an unusually wide range of frequencies, spanning from 0Hz to several hundred kHz, depending on the application. Typical applications include condition monitoring, verification of operating conditions (e.g. for flapper valves), and evaluation of the structural health of pipes and supporting structures.
Multiple configurations are available, such as:
The vibration monitor can be affixed to almost any part of a subsea production plant, including;
The instrument provides logging and/or streaming of raw vibration data at configurable sampling frequencies up to 2000 samples/second, as well as internal spectrum analysis and other digital signal processing.
Inspection job subsea Caspian sea to monitor vibration on large valve.
Instrument installed in Valve bucket using ClampOn’s magnetic locking solution
Vibration monitoring can be combined with other standard ClampOn sensor products, such as sand monitoring, PIG detection or ultrasonic spectrum analysis.
