Eagle Ray AUV Achieves Depth Milestone (USA)

Eagle Ray AUV Achieves Depth Milestone (USA)

International Submarine Engineering Ltd learns of its customer’s new depth record obtained by the ISE Explorer Autonomous Underwater Vehicle (AUV) ‘Eagle Ray’, a cooperative venture of the University of Southern Mississippi and the University of Mississippi. Operated by the National Institute for Undersea Science and Technology (NIUST), the Eagle Ray AUV completed a survey in the Gulf of Mexico to a depth of 1634 meters.

“This is a new depth record for Eagle Ray and she performed brilliantly,” stated Roy Jarnagin, Undersea Vehicle Systems Engineer for NIUST. “The survey was conducted at 50 meters altitude while acquiring multibeam sonar and chirp subbottom profiler data. We are currently operating from the LUMCON vessel RV Pelican. The AUV operations personnel in addition to myself are Dr. Arne Diercks, Max Woolsey, Marco D’Emidio, Steven Tidwell, and Clayton Dike.”

Initially built and delivered in 2003, the Explorer class AUV is rated by the USM for deepwater operation to 2200 meters. Its 5.5 meter length provides payload volume for mission-specific sensors, as well as the multibeam sonar and conductivity-temperature-density (CTD) sensor. Surveys greater than 150 km long and deployments over 36 hours in duration can be achieved.

In addition to Eagle Ray, NIUST operates a Woods Hole Oceanographic Institution (WHOI) SeaBED class AUV named Mola Mola. This vehicle also completed a mission to a depth of 1612 meters. The Mola Mola vehicle acquires photographs of the seabed while operating at 3 meters altitude.

Explorer is ISE’s current medium size AUV. It is available in several depth ratings and configurations to satisfy the needs of scientific, defence and commercial sectors. In addition to USM/UM, Explorer AUVs can be found with esteemed organizations around the globe including Ifremer, France, University of Bremen, Germany, and Natural Resources Canada (NRCan). NRCan’s Arctic Explorer AUVs are two vehicles performing under ice survey missions. The Arctic Explorer AUV completed more than 1000 kms of unsupervised survey. This was the first sea floor survey under the ice by an AUV. It also recorded the second deepest dive by an AUV in Arctic waters of 3162 meters.

ISE also built the Theseus AUV. It was designed to lay 220 kilometre fibre-optic cables in the Arctic for the Canadian and US navies. Theseus was deployed to the Arctic for trials in 1995 with cable laying missions taking place in 1996. Until very recently, Theseus was the largest AUV in operation and held the record for the longest AUV mission – 460 kilometres, all of which was under ice.

Substructures for UK Offshore Wind

Design, construction and installation

Optimising offshore substructures is one of the key challenges for reducing LCOE. Foundation designers have produced a variety of different solutions: monopiles, GBS, jackets, suction buckets and floating foundations. Looking at U.K. projects – different soils, water depths,fabrication timelines and installation challengescreate many questions for the industry to solve. We’re entering uncharted territory; projects arelarger, farther and more complex than ever completed.

Now is the time to have a close look at lessons learnt and define the room for improvement for the U.K. wind industry.
