PET - Pipeline Environment Tool
The PET is an ATEX certified multi-channel, self-contained, data logging
instrument that can be fitted to standard pigs ranging from 8” – 56”.
A cost effective solution for many pipeline flow problems, the PET
can be adapted to fit inside the customer’s own pig or is available ready cupped.
It is a self-contained pipeline data logger which is pressure switch activated, microprocessor controlled with
onboard non-volatile memory and power supply.
The PET has been designed to be flexible in that different types of sensors can be added to the
versatile electronics framework. This allows the PET to be configured to suit the client’s
requirements by the addition of more or ‘special’ sensors e.g. 6 axis MEMS unit used for vertical
profiling of the pipeline along with accurate bend measurement, conductivity used when measuring
a liquids level on conductivity.
Pipeline Conditioning Monitoring
The PET can be run as part of a pigging programme that monitors pipeline
conditions at different times, events and flow rates. It can also be used to perform a
reconnaissance pig run prior to an intelligent tool checking the pipeline condition is
suitable for the IP passage.
Pipeline Pressure and Temperature Profiles
Pipeline pressure and temperature profiles can be used to pinpoint areas of hold-up in the
pipeline, such as dents and wax/scale build-up. The information can be utilised in
conjunction with pipeline modelling software and used to establish pipeline insulation
effectiveness and assist in inhibitor selection.
Pipeline Velocity Profile
Odometer wheels provide an accurate, direct measurement of distance travelled along
the pipeline and pig velocity within the pipeline. This information can be used to pin-point
anomalies identified within the pipeline as well as evaluate anticipated product flow rates
produced by flow modelling software.
Semi-intelligent Multiple Pigging Capabilities
Run as a gauge pig, the information recorded by the PET will identify exactly where any
gauge-plate damage occurred in the pipeline. A PET mounted onboard cleaning,
scraper, gauging or other utility pig can provide a concurrent indication of the pipelines
cleanliness, geometry and operational conditions.
