Saab Seaeye's Falcon Flies High

In 2020, Saab Seaeye sees the Falcon flying high as the top-selling electric underwater robotic vehicle in its 34-year history.Launched nearly 20 years ago, its design has kept the pioneering concept in step with two decades of global technological advances.The Falcon has opened up many new sectors to the potential of robotics, from marine science to aquaculture and from wind energy to hydroelectric dams.The design created a small, powerful, multi-tasking, easy to use, reliable and robust vehicle - with intelligence.Just a meter-long and rated 300 to 1000 meters depth, the Falcon’s five powerful

blocks. Saab Seaeye, a firm well versed in all-electric vehicles, has been making noises in this direction, using the smarts it’s been developing for the Sabertooth for new electric vehicles.Another firm looking to enter the resident vehicle space is UK-based subsea machinery firm SMD. During Offshore Europe, it launched its Quantum EV ROV. While the Quantum EV ROV made the headlines, what SMD launched was a technology suite, rather than a single ROV, based on an open-electric framework for whatever shape vehicle is required and that can be adapted for a variety of tethered or untethered operations

, where it would aid the deployment of marine robots in the execution of duties ranging from subsea surveying and Search & Rescue to mine detection and clearance.“It could also be installed into an AUV hangar on a platform supply vessel, facilitating a broad range of subsea tasks related to the offshore oil & gas infrastructure, or even retrofitted in a containerized solution. Coupling this new LARS with our highly maneuverable, stable, compact and customizable HUGIN AUVs, which utilize a modular payload system capable of accommodating a comprehensive variety of sensors, will transform commercial

SubSeaSail G6 Platform Passes the Test

The Engineer Research and Development Center (ERDC) of the U.S. Army Corps of Engineers (USACE) along with logistical support from the US Navy successfully tested their SubSeaSail G6 platform at multiple coastal sites off the Vieques Island, Puerto Rico. Remote sensing applications for monitoring underwater unexploded ordnance were demonstrated by mounting a passive filter assembly to the G6 platform to detect explosive compounds in the water. Additionally, a water quality sensor was mounted to monitor other water quality parameters including temperature, salinity, depth, and turbidity.  During

Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency

It is easy to appreciate why permanent magnet synchronous motors (PMSMs) are popular for use in underwater vehicles (UVs). They are compact and efficient with a high power density. More importantly, perhaps, they allow for effective operation across a broad RPM range which is beneficial for vehicles with multiple operating conditions. That said, we find vehicle product developers are often uncertain about a motor’s “efficiency”. This article offers a few comments from the perspective of a propeller designer, developing the components that puts the load on a UV’s motor.We first

U.S. to send envoy to Saudi Arabia to Stabilize Oil Prices

The Trump administration plans to send a special energy envoy to Saudi Arabia to work with the kingdom on stabilizing the global oil market, officials said on Friday, as the U.S. scrambles to deal with a price crash so deep that regulators in Texas considered curbing production there for the first time in nearly 50 years.Oil prices have lost more than half their value in the last two weeks as Saudi Arabia and Russia kicked off a price war and the coronavirus pandemic destroyed demand. U.S. oil now trades at less than $23 a barrel.The crash has shocked the oil industry as a pact among OPEC and non-OPEC
