SMD Sells its First Electric ROV
collaboration with fellow innovator, SMD. Once built, the Fleeming Jenkin will be the world’s largest and cleanest cable-laying vessel. Our attention to environment and climate is mirrored in SMD’s Quantum EV, which not only offers superior efficiency and reliability but also consumes less energy and drastically reduces the risk of oil contamination.&rdquo
Back to the Future: Blended Wing Gliders Could Redefine Undersea Warfare
for propulsion, they rely on changes in buoyancy, in combination with wings and stabilizers, to "fly" through the water column in an up-and-down, sawtooth fashion, periodically surfacing to communicate with human operators ("pilots"). Although battery-powered, gliders consume less energy than AUVs using conventional propulsion, leaving more to power onboard sensors, C2, and communication systems. They are inexpensive, deep diving (anywhere from a few hundred to several thousand meters), capable of accommodating a range of sophisticated sensors, and can remain in situ for weeks
Reader Feedback: Lander Lab - Buoyancy
! Argo floats use the idea of variable displacement by pumping oil across a bulkhead to create buoyancy. The idea is that the displaced volume changes while the net mass remains the same, thereby changing density to some value greater or less than 1. It would take a smaller volume and less energy if the material were a "liquid syntactic” with a lower specific gravity, as you coin the term.As one suggestion for your application, I use mineral oil (baby oil) for a number of p-comp applications. It has a specific gravity of 0.845-0.905, and is about as benign an oil as you
Subsea Compression: A Step Change at Ormen Lange
uniquely positioned in Norway, with hydroelectric power feeding this system, which is fantastic when it comes to lifecycle emissions. But it’s also important to consider that subsea compression is much more efficient than topside compression. When we compress on the seabed, we use at least 50% less energy than topside, and this technology can be applied globally.”It’s also not just about technology. To realize complex projects, collaboration is key, adds Richard. “To deploy this type of technology in fields such as Ormen Lange, close cooperation within the Ormen Lange license
Rapid Testing Facility for Tidal Turbine Blades Opened in Scotland
opened in Fife, Scotland, on Friday as part of a partnership between the University of Edinburgh and Babcock.The facility will stress test blades made from composite materials – which must withstand harsh ocean conditions for 20 years – more quickly and will use significantly less energy than any other facility of its kind, according to Babcock.Based at Babcock’s Rosyth site in Fife, the £4.6 million (USD 5,6 million) facility was officially opened by UK Government Minister for Scotland Malcolm Offord, supported by a £1.8 million grant from the UK Government
Report: Population of North Atlantic right whales Hits 20-year Low
, specifically entanglements in fixed fishing gear and vessel strikes, remain the biggest threats to the survival of this species. Recent research shows that body lengths of right whales have been decreasing over the past four decades, with life-threatening entanglements leaving individual animals with less energy to devote toward growth and reproduction. New England Aquarium research has also shown that 86% of identified right whales have been entangled one or more times in fishing gear.“There is no question that human activities are driving this species toward extinction. There is also no question
Can the Subsea Factory Support a Net Zero World?
zero, for a number of reasons. Subsea developments in general, compared with conventional topside developments, have a significantly lower carbon footprint, because we are installing advanced rotating machinery and processing systems on the seabed that are enabling improved recovery, while using much less energy.A conventional way of producing subsea fields is using gas lifting—a textbook standard for petroleum engineers. By contrast, with subsea boosting, you can achieve the same result, but with the additional benefit of a reduction in energy consumption by about 50-80%. That’s a substantial
ArgoX90: Rocket Recovery Boat
“sway” turns, whereby it can rapidly move in a lateral direction without having to turn the entire vessel. Instead of having to turn one or more long hulls of a conventional monohull or catamaran, the short individual hulls are far more maneuverable and can be rotated quickly and with less energy. The design is also lightweight and minimalist, further contributing to performance and maneuverability.To rotate the hulls each of the four 300hp outboard motors are turned using a drive by wire control system. To perform a “sway” turn, where the platform orientation remains constant
Pipeline Breaks GoM Depth Record
. Energy efficient inverters have replaced more than 50 traditional transformers/rectifiers on production lines to enable quick and repeatable set ups at industry-leading levels while cutting the mill’s electricity demand by nearly a third, allowing Tata Steel to produce more pipe with less energy. The mill’s ‘O’ press control has been upgraded to optimize the forming process, ensuring uniform pressing along the full length of pipes to achieve optimum pipe shape. This has benefits for deepwater operations, as both the shape and balancing of the ‘forming
