NCS Survey acquires two more AUVsVessel & ROV News // January 31, 2013
NCS Survey has expanded its growing autonomous underwater vehicle (AUV) fleet with the purchase of two Teledyne Gavia AUVs.
The vehicles are the latest in the Gavia Offshore Surveyor series and are equipped with high-resolution side scan sonar, a multi-beam echo sounder, a sub-bottom profiler (SBP), 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 windfarm surveys.
For three years, NCS Survey has operated these vehicles in difficult 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.
The company now claims to have the largest commercial fleet of AUVs in the world. The new 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 jack-up 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.
