locations on rotations, and this is a new way of working.To accomplish this, our equipment has to be reliable. We are investing significant energy and resources into improving systems reliability, along with component and material qualifications, so that today’s ROVs can become resident subsea vehicles that can be controlled remotely and operated with minimum to zero maintenance.What do you count as the most important technology, or technology trend, that has made ROVs more efficient and cost effective?Software and control systems – the two go hand-in-hand. They allow us to optimize

“We are moving autonomous technologies into vehicles that have always been "remotely operated" or even manned to realize more efficiency and capability.  We are really blurring the lines between "ROV" and "AUV" and minimizing the technical difference between manned and unmanned. ”

Subsea: The Future of Unmanned Vehicles

Subsea vehicles of every shape and size have evolved mightily in the past few years, as a confluence of communication, electronic and autonomy technologies have conspired to increase the accuracy, duration and efficiency of such systems. MTR tapped a few key industry leaders to discuss the path ahead.“I think there are two current market drivers forcing the industry to develop and adopt technologies that make subsea vehicles more efficient and effective,” said Ben Kinnaman, CEO, Greensea Systems, Inc. “First, the market really wants to use miniature vehicles and realize the long-promis

batteries that are safe, smart, provide more capacity, deliver more power, are smaller and lighter, longer life, and highly reliable.For years, most electrical subsea operations were tethered, powered by umbilicals, which are costly, constraining, and require significant lead time.  Untethered subsea vehicles used sealed lead acid, which made them heavy and bulky, or batteries contained within 1 atmosphere pressure vessels, which can be expensive and heavy.Six years ago, Southwest Electronic Energy Corp’s SeaSafe battery brought revolutionary changes to the market. The first commercial pressure-tole

months?We are optimistic on the health of the marine market across all market sectors over the next 12 to 24 months. Our interconnect and instruments businesses are beginning to see the effects of stabilization in what has been a weak energy market over the past few years. Interest in our autonomous subsea vehicles and interconnect for both U.S. and international government applications has been strong with expectation to continue to grow. Finally, due to the aging of U.S. infrastructure and increased demand on the global fish supply, we expect the civil engineering market and aquaculture markets to strengthen

It showed a lot of internal structure in the data, says Evans, “water over flowing over each other bouncing off bathymetry, 3-4m/sec in some places, with interesting shear profiles.”VisualisationA number of projects are focusing on subsea visualisation technologies supported by subsea vehicles, to assess offshore renewables assets. An OWA project will see Kraken Robotics demonstrate its SeaVision 3D RGB Underwater Laser Imaging System on foundations. An initial system, incorporating a high-resolution camera and laser to create as built point cloud models, was designed for deployment

ION Sells Compasses for Subsea Vehicle Navigation

ION announced today the second sale of a number of its highly differentiated optical magnetic heading sensors to enable subsea vehicles to quickly reach their desired destinations.In the fourth quarter, successful field trials demonstrated the advanced compasses’ accuracy in GPS-deprived environments and led to delivery of the first commercial order in the first quarter.In less than a year, ION's devices business line made adjustments to adopt the compass offering from ION’s towed streamer positioning solution to suit the underwater vehicle market’s navigation requirements.

Unmanned Vehicles May Soon Take Up Residency Subsea

there are still various challenges, however, including the readiness of subsea infrastructure for resident vehicles, regulation relating to unmanned vehicles, and skepticism and resistance to change. But, with a string of roadmaps in place, from vendors to operators and service providers, resident subsea vehicles are just a matter of time.(As published in the May 2018 edition of Marine Technology Reporter
