An EdgeTech 4200 Series Side Scan Sonar System installed on two MacArtney Focus-2 ROTVs owned and operated by Noordhoek Survey has just completed its first project; a pipeline inspection in the North Sea.
The Focus-2 vehicles were used to inspect roughly 600 km of pipeline and utilized EdgeTech’s 4200 Series Side Scan System with high frequency 300/600 kHz arrays.
Aboard the vessel during the pipeline inspection campaign the onboard geophysicist Professor Jean Lanckneus commented, “The side scan data acquired was of outstanding quality. The stability and maneuverability of the ROTV combined with the noiseless environment provides the obvious choice for all future side scan operations”.
Additionally, representatives at Noordhoek had the following to say: “The data recorded was quite simply excellent, proven by the sample below. The pipeline entering the protective structure is seen quite clearly and even the gaps between the mattresses covering the pipeline on the port channel are displayed.”
ROTVs have become popular in recent years, especially for use on pipeline inspection surveys. EdgeTech can provide systems for most ROTVs as well as engineered to order systems for custom marine applications where gathering of sonar data is required.
