Two More Gavia AUVs Delivered
NCS Survey has expanded its growing autonomous underwater vehicle (AUV) fleet with the purchase of two Teledyne Gavia AUVs. These vehicles are the latest in the Gavia Offshore Surveyor series and are equipped with high-resolution side-scan sonar, a multibeam echo sounder, a sub-bottom profiler, an ultra-short baseline positioning system, long baseline (LBL), GPS and an inertial navigation system.
The AUVs are used to provide ultra-high-resolution data for pipeline and platform inspections; scour monitoring surveys; cable and pipe route surveys; and offshore wind farm surveys. For three years, NCS Survey has operated these vehicles in difficult to access and remote areas including the southern tip of Argentina. Additionally, the company has a high level of repeat business from clients like Shell, BP and ConocoPhillips.
2-1,000m Depth
The vehicles are rated to 1,000m but regularly operate in depths as shallow as 2m. They can perform in currents of more than 2 knots, under jackup drilling rigs and very close to fixed platform structures. Their modularity offers ease of transportation as no module weighs more than 25kg in its transit case.
