ASV Global and Terrasond Mark Industry First for Unmanned Hydrographic Survey

ASV Global and TerraSond have completed a 5172 nautical mile hydrographic survey in the Bering Sea, off Alaska.

TerraSond used the C-Worker 5™ Autonomous Surface Vehicle (ASV) alongside its Q105 survey ship for a duration of 36 days. The C-Worker 5™ completed 2275 nautical miles of survey lines operating as a force multiplier, running parallel survey lines to the Q105. Both vessels ran multibeam sonars and simultaneously towed side scan sonars.

The C-Worker 5™ is the ideal platform to support hydrographic survey work.

The C-Worker 5™ was operated using ASV Global’s ASView™ control system from a control station on the Q105 vessel. ASView™ used exported survey lines from the TerraSond planning system to autonomously execute an accurate survey with minimal human intervention. Navigational safety was maintained by the C-Worker 5™ operator monitoring the ASV’s colour and thermal camera feeds and AIS collision avoidance system, whilst radar overwatch was provided by the Q105.

Thomas Chance, Chairman ASV Global said “The C-Worker 5™ has proven itself as a reliable, weather resistant solution to increasing survey efficiency. The ASV covered up to 130nm per day, doubling the coverage of the Q105 survey vessel. In addition to this, the C-Worker 5™ was able to survey shallow waters that the Q105 was not able to reach”.

Thomas Newman, President, TerraSond said “I have been involved with hydrographic surveys for more than 30 years, and I can say that the production improvements due to ASV Global’s unmanned force multiplier were nothing less than astounding. Using the C-Worker 5™ system alongside our survey vessel, we were able to reduce our overall time on site by more than 25 days”.

This 2016 deployment was a follow on from a proof of concept operation carried out between TerraSond and ASV Global in August 2015 during which an ASV platform became the first autonomous surface vessel to update the US nautical charts for NOAA.

ASV Global is a world leader in autonomous marine technology. In just six years, ASV Global has produced more than 80 vehicles and developed more than 30 different payload packages. Products are available for lease and purchase alongside comprehensive support and training packages. The company has also converted numerous existing vessels to operate autonomously using it’s proven ASView™ control system. With offices in the UK, US and Brazil, ASV Global’s 70+ employees support commercial, scientific, and military clients across the globe.
