If every pipeline system were the same, our job would get pretty monotonous.

Luckily, clients come to UPP with unique challenges that keep us on our toes.

UPP specializes in smart PIGS for pipeline inline inspection, but what happens when you encounter a pipeline system deemed “unpiggable”? These systems are tough to inspect using traditional methods because of complex shapes, low flow rates, or other factors that make regular tools ineffective. Fortunately, we have reliable solutions to help pig the unpiggable.

Tethered Pipeline Inline Inspection

Wire-line (tethered) inline inspection services are typically needed for pipelines which are challenging to pig due to a breach or dent. These systems may have sharp turns, varying diameters, or other obstacles preventing the use of free-swimming inspection tools.

Pipelines with low flow rates or those not in constant use may also require this specialized inspection method. Without proper inspection, issues like corrosion, cracks, or other damage might go unnoticed, potentially compromising the pipeline’s safety.

How does Tethered Pipeline Inspection Work?

Unlike free-swimming pigs that move with the pipeline’s flow, tethered tools are tethered via a wire-line, which allow our wireline trucks to pull our bi-directional UXD Inline Inspection Tool backwards.

The tether provides power and real-time communication, allowing data collection and analysis during the inspection. The data includes clear images and precise measurements, helping identify issues like corrosion, cracks, and metal loss.

Advantages of Wire-Line Inline Inspections

A major advantage of wire-line inspection is its ability to access difficult-to-reach pipelines. It can navigate tight turns, adjust to different diameters, and even move uphill or downhill.

This flexibility ensures a thorough inspection, reducing the risk of missed issues and giving operators accurate information to create detailed ILI reports that highlight the maintenance and repairs that should take place.
