ROV Pipeline Inspections & Repairs in Subsea Environments

Shannon Regan   |   July 18, 2018

Deep Trekker remotely operated vehicles are being used to inspect and repair structural damage to offshore pipeline and subsea infrastructure.

Preventing Leaks by Performing Submerged Offshore Pipeline Inspections


Pipelines made prior to the early 1970s are often considered as aged or old pipelines. Their metallurgical constituents and external corrosion coating effectiveness are of lower standard compared to pipelines of today. Often, there are leaks that cause catastrophic disasters on offshore structures. Said issues can cause environmental degradation, public scrutiny and safety compromises.

Many aged structures have suspected weak points and smaller leaks that over time become larger, creating worsening conditions for the structure.

Offshore Pipeline Inspections using ROVs

Leaks and pipeline degradation can be avoided through regular maintenance and inspection using Canadian-made Deep Trekker remotely operated vehicles (ROVs). A pipeline repair in general requires a range of planning, such as inspection of the damage, pipe condition and consequences for the pipeline operation. Close observations or inspections of items existing below the water surface become difficult when the water has low visibility.

Our units are equipped with external LED lighting in addition to the internal LED flood light that tracks with the camera, to allow for visibility in even the darkest and murkiest waters. The internal 4K camera allows for real time visual conditions of pipelines, providing the operator with a historical log to highlight changes made over time, rather than having to rely on a single day inspection.

Deep Trekker ROVs are made with simplicity in mind. The innovative magnetic coupling at the seals reduces the need for extensive training on how to maintain the ROV – oiling and/or greasing is not required.

DTG2 and DTX2 Remotely Operated Vehicles

The DTG2 and DTX2 ROVs combined with advanced sonar allow for threat detection underwater up to 300 meters in depth, both from shore or by divers in the water. Often, if we can’t see it, we pay no mind to it. Deep Trekker robotic systems are designed to go places that the human often cannot reach. There is tremendous amount of underwater infrastructure with need for repairs that people don’t know about. Deep Trekker creates awareness by making tools that help uncover our underwater world to keep operators and civilians safe.
