How is ROV used in pipeline surveys?

When we think of large water bodies, most of us immediately imagine oceans and seas, but there are many more to consider. Places like reservoirs and submerged infrastructures need regular maintenance, but it is impractical or dangerous for humans to foray into these deep waters.

This is where the ROVs come in since they can safely reach places where humans cannot and carry out inspection. ROVs have helped a great deal to improve the safety of this inspection procedure. If you are curious about ROV pipeline inspection, then read the article further.

How do ROVs help in pipeline inspection?

The introduction of ROVs in the pipeline inspection and survey has been a game-changer since it has addressed many challenges in the industry. There have also been advancements in the build of the ROVs, and this has come at the right time when there has been increase in the subsea infrastructure. Here are some of the advantages of ROV pipeline inspection.

Cost efficiency: This has been the major driving factor of use of ROVs in pipeline inspection. Usually, for single-inspection job, 2 to 3 divers are employed. Compared to both human inspection and the large submersibles employed for the job, ROVs cost much less. The initial cost to purchase the ROVs might be high, but you can use it repeatedly for the inspection once you get it.

Safety: ROVs are safe for inspection of dangerous underwater areas when compared to inspection by divers. The ROVs can be deployed by operators while staying in safe areas. There are jobs that require human inspection. In that case, ROVs help in determining the safest route for the divers while inspecting all possible routes.

Extended dive time: Though divers will be provided with the required equipment, they can remain submerged only for up to 30 minutes to 1 hour. Depending on the quality and the battery life of the ROVs, they can work underwater for a longer duration.

Ability to explore confined areas: Depending on the size of the ROVs, they can reach places during the inspection that are not possible by divers. For example, our Phantom L5 ROVs have a total weight of 97.5kg and come with compact design, thus making it easier to navigate and reach inaccessible areas.

Time-saving: Due to the smaller proportions and easily operable technology, the ROVs can be deployed on short notice. Also, most ROVs come with camera and laser provisions, which help gathering the data faster. This also means reduced health, safety and environment (HSE) exposure, and carbon footprint for the operators.

Help in improvisation: The technological advantages like high-resolution cameras and variety of sensors have revolutionised the data that can be received during the inspection. These new data have helped improve the management of pipeline integrity. This also helps store the details of the inspection for future reference.

Easy maintenance: High-quality ROVs are built to survive harsh environments and thus would only need minimal maintenance. For example, our Phantom L5 ROVs are hand-built and come with rugged and non-corroding chassis. Also, the ROVs can go on for years without the need for major repairs.
