In mid-2011, UTEC Survey received its first Gavia AUV. UTEC conducted successful initial surveys utilizing the Gavia in South America in the fall of 2011 A second Gavia vehicle was ordered soon after, which was delivered in the first quarter of 2012. “UTEC is committed to investing in the best equipment and the most recent technology to offer our customers the highest level of service. We continue to work closely with Teledyne Gavia and others to develop new modules and enhance the capabilities of these class-leading AUV’s” said Ken Adams, UTEC’s Chief Technology Officer. Both Gavia vehicles owned by UTEC Survey include the full survey suite of a 500kHz GeoSwath module from GeoAcoustics, a Teledyne Benthos Sub-bottom Profiler (SBP) , a Marine Sonic Technologies Limited side scan sonar, and a camera system. For optimal navigation, the vehicles are equipped with a Kearfott T24 Inertial Navigation System (INS), partnered with a Teledyne RDI Workhorse Doppler Velocity Log (DVL).

UTEC Survey was initially introduced to the Gavia AUV through a cooperative agreement with the University of Delaware’s Coastal Sediments, Hydrodynamics & Engineering Lab (CSHEL), where associate professor Dr. Art Trembanis has been performing research with the University’s Gavia AUV since 2008. Partnering with the University of Delaware allowed UTEC to observe and familiarize themselves thoroughly with the performance of the Gavia system prior to placing an order. “We are very excited to strengthen our relationship with UTEC Survey and look forward to a long and mutually beneficial partnership,” stated Arnar Steingrimsson, Teledyne Gavia’s Director of Sales and Marketing. “We look forward to working with UTEC and other commercial survey users to optimize the Gavia AUV as the AUV of choice for commercial survey applications.” Teledyne Gavia’s “Offshore Surveyor” is increasingly being utilized by commercial survey companies where the low logistics approach and modular design of the Gavia, coupled with a 1000m depth rating allow for considerable cost savings in the survey role when compared to traditional means. Utilizing costly vessels with ROVs or towed assets, or larger AUVs that require the presence of a large surface vessel and which have a considerable shipboard footprint give the Gavia AUV a significant advantage in the marketplace.
