To start an underwater pipeline project off right, divers need the right equipment to locate their work site. An article in last month's Underwater Magazine looked at the call for divers to identify the best spot for laying cables for various construction efforts. While regulations can push these sites far underground away from hazards, this could make it hard for divers to find the best location for a new line.
As such precision pays off for the operators, and may be essential to avoid conflicts. On land, markers help signal where pipelines run. While this has been part of the underwater pipeline process, recent advances in technology have given divers less intrusive ways to inspect possible sites.
For successful pipe tracking, users may have to consider a few different factors. First, the distance of scan is important: cable trackers can give readings from more than 30 feet away from the target, the article stated.
"The need for accurate detection may only increase over the next few years."
Furthermore, commercial diving workers may need to consider the type of water they're working in. JW Fishers' PT-1 Pipe Tracker is designed for both salt and fresh water use, as an example of a magnetometer fit for this job. It can also be used on land if necessary.
The need for accurate detection may only increase over the next few years. According to a forecast from Research and Markets, the next five years will see the hydrographic survey equipment market grow to more than $3.6 billion.
Ferrous metal detection, something the magnetometer is meant for, will be a major factor for non-acoustic marine geophysical systems this year, a press release from the company said.
Marine industry insurance may help operators feel better about using sensitive equipment, especially if it represents a major cost.
