General Overview

The magnetic, electromagnetic and ultrasonic subsea PIG detector DSES is designed to detect and register the passage of a pig inside the oil, gas and multiphase pipeline in offshore subsea pipelines.

The triple sensing technology provides reliable detection of pigs of any type. The acoustic pig detector technology can be used on any type of pig.

DSES is distinguished by incredible noise immunity, which excludes false triggering and skipping of the in-tube object. Convenient mounting of the sensor will shorten the time for installation and further startup.

Conclusion on the passage of the pig is done when the thresholds are exceeded by not less than two channels – according to the acoustic (always) and electromagnetic or magnetic.

Levels of generalized threshold values are set by choosing parameters for each channel separately using specialized software.

The subsea acoustic Pig Detector DSES can operate at depths up to 4500 meters.

ROV Handle type provides D-Handle as standard (T-Handle, Fishtail handle, O-handle available upon request)
