Sound Velocity & Bathymetric Sensors for Sustainable USV Fleet

Published: 25 Oct 2021 by

Valeport sensor technology has been selected by Ocean Infinity to provide sound velocity and bathymetric data for their pioneering Armada Fleet, the world’s most environmentally sustainable fleet of Unmanned Surface Vehicles (USVs).

The Armada Fleet, capable of remotely operated unmanned operations, is breaking new ground in the remote and autonomous seabed data industry. Integrating a suite of Valeport’s highly accurate sensors and profilers to a selection of the fleet’s USVs will provide important data to support operations for Ocean Infinity.

Valeport’s miniSVS will be mounted on the vessels beside the multi-beam echosounder in the sensor gondola, to provide surface Sound Velocity correction. 

Through the water column, the Midas SVX2, powered by the vessel, will deliver the sound velocity data of an SVP with the salinity and density data from a CTD. It has also been combined with the VA500 altimeter to provide range data for the vessels. 

Selected to interface with the Edge Tech side scan sonar and Saab Seaeye Leopard Remotely Operated underwater Vehicles (ROVs), the Valeport uvSVX will be integrated onto the vessels to deliver sound velocity, temperature and salinity combined with range data from the VA500 altimieter and precision depth from the miniIPS2.

The compact and robust instruments will be fitted across a selection of six USVs in the fleet, including the 21-meter and 36-meter vessels, to assist their offshore data acquisition and ROV work in both shallow and deepwater operations.

Valeport has already delivered the first instalment of instruments to Ocean Infinity’s facility in Southampton, U.K. and further deliveries will be made throughout 2021 and 2022.

The robotic vessels in Ocean Infinity’s Armada Fleet use low emission technology, with an Armada USV emitting 90% less CO2 than a conventional survey vessel.

“The Armada Fleet is an exciting demonstration of uncrewed, and sustainable, seafaring technology and we are very proud that Valeport technology is involved in this innovative project,” said Kevin Edwards, Head of Sales at Valeport.

“These exceptionally efficient vessels undoubtedly will play an important role in the future of data acquisition and maritime activity, and the stable, high accuracy data performance from our instruments can play its part in helping to underpin this.

“Working with Ocean Infinity engineers is an interesting project and we are pleased to offer them the solution required.”
