Mission Record for Gavia AUV03/02/2010 |
| Fugro Survey Pty Ltd in Perth and Hafmynd Ehf, in a joint initiative with Woodside Energy Ltd, have successfully trialled a Gavia Autonomous Underwater Vehicle (AUV) down to a subsea depth of 1000m. This significantly surpasses the previous maximum recorded depth of 220m achieved by a Gavia vehicle. |
 The Gavia AUV is a relatively small and portable AUV, manufactured in Iceland by Hafmynd. Its modular configuration enables the inclusion of various payloads in addition to the base vehicle configuration, such as an Inertial Navigation System, GeoSwath bathymetric sonar and additional battery modules for increased endurance.
"This model purchased by Woodside has been optimised specifically for use in the offshore survey industry. It's been fitted with an underwater camera, sidescan sonar, multibeam echosounder, highly accurate INS, and navigation software which enables the AUV to automatically track a pipeline on the seabed," explains Ian Hobbs, Geophysics Manager of Fugro Survey. "Fugro Survey Pty Ltd will manage all aspects of the Woodside Gavia AUV, including supervision of the factory and customer acceptance trials, personnel training, field operations, and maintenance and storage of the vehicle.
"We recently ran some Customer Acceptance Trials offshore Perth, Western Australia which included a record-breaking dive to 1000m. The Gavia AUV was set to run a grid of survey lines at an altitude of 12m above the seabed recording both side scan sonar and swath bathymetric data. This was followed by a survey line run at only 2m above the seabed, to collect seabed habitat photographs.
"Overall, the Customer Acceptance Trials went very well demonstrating that the Gavia AUV is a highly capable and versatile vehicle."
Woodside anticipate using the AUV primarily for pipeline inspection surveys, as well as for near-shore environmental surveys, debris surveys in restricted areas, and deepwater inspections of flowlines and other seabed infrastructure. The vehicle will be utilised from vessels of opportunity and is available for surveys for third party projects.
More detail on the Gavia AUV and this project will be available on the Fugro stand (E100) at Oceanology International 2010 (9th to 11th March 2010, ExCeL, London).

Hydrographic Survey of Riverbed Erosion |
Members of the US Geological Survey were filmed while out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyses the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.
