Remotely Operated Vehicles: Thinking out of the Box

All electric systems are starting to free companies from the traditional strict form factors that ROVs traditionally take. With a more flexible modular harness, vehicles can be built from standardised building 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

This instrument, while functional, is larger and challenging to deploy.More recently, a new version of the ESP has been developed for use aboard an autonomous underwater vehicle (AUV). In 2009 MBARI initiated an effort to re-engineer the ESP to fit on the long-range AUV, a novel AUV developed there. The new instrument, like its predecessor, was designed for both select sample analysis and sample preservation. Unlike its predecessors, however, the new ESP design concept

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

MBARI Works at Unlocking Ocean Biology

Greater understanding of what goes on in the ocean is starting to become a reality – thanks to growing use of unmanned surface and underwater vehicles and developments in biological sensing.  Elaine Maslin takes a look at what a team at MBARI has been doing.Gathering biological data from the oceans remains a significant challenge for oceanographers. Now, an increasing range of unmanned vehicles that are able to work together is becoming available, as is an ability to collect biological data using them.It sounds straight forward, but traditionally the collection and processing of biological

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
