roxar subsea sand monitors
The Roxar™ Subsea Sand Monitors are intelligent non-intrusive devices that provide an immediate response to the onset of sand production.
The monitors utilize the acoustic noise produced by sand particles to calculate real-time sand production in oil, gas or multiphase pipeline flows. Such information leads to improving the integrity of operator assets and optimizing oil & gas production.

Features

  • Acoustic based sensor provides an immediate response to the onset of sand production.
  • Compact, robust design provides easy installation and retrieval on the outside of the subsea production pipe-work.
  • ROV retrievable and Non-retrievable models are available, both mounted in fixed pre-installed clamps with guide funnels.
  • Can be used with Roxar Sand Erosion Sensors to positively confirm the occurrence and severity of a sand event, giving operators complete control over sand production.
  • Connect to Roxar Fieldwatch monitoring software for in-depth analysis and investigation of process changes.
