Customers are starting to fully understand the cost and risk mitigation benefits of unmanned systems. Both military and commercial markets are showing encouraging growth as they are now incorporating unmanned vehicles and intelligent sensors in their procurement plans and budgets. In fact, industry analysts Market Info Group estimates that the

WHOI scientists used deep-sea vehicles, including Sentry to locate the voyage data recorder (above) from the El Faro on the seafloor 15,000 feet deep. The VDR offers clues to understand why the ship tragically sank in 2015, killing 33 crew members aboard. (Photo: NTSB)

Why Did the El Faro Sink?

. A search expedition mounted in October located the wreck and discovered that the bridge had separated from the hull. Days later, when the search team located the bridge, the mast and the VDR were not on it. In April 2016, the National Transportation and Safety Board (NTSB) asked for help from Woods Hole Oceanographic Institution, calling in two deep-sea vehicles WHOI operates for scientific research.   Aboard the WHOI-operated research vessel Atlantis, a coordinated team of scientists and engineers from WHOI, NTSB, and the Coast Guard deployed Sentry, a WHOI autonomous deep-sea vehicle equipped

Modus unveils Saab Sabretooth for cost effective survey, inspection

with Saab Dynamics, Modus has developed the Saab Sabretooth to offer greater endurance and speed, and is also developing advanced sensor payload packages and operating methodologies. The vehicle is expected to contribute to more cost-effective survey and inspection projects in the offshore, defence and oceanographic sectors. First commercial use Following successful trials in Sweden and the UK, Modus is preparing the advanced spread for its first commercial deployment. The system will be used to fulfil pre-engineering, construction support and life-of-field condition monitoring requirements. The
