DOF Subsea, Sonardyne, 2G Robotics, and Seatronics successfully demonstrated a new underwater surveying technique that could significantly shorten the time needed to map underwater structures and offshore sites. The new technique uses a 3D laser scanner fitted to an ROV to create highly detailed, point cloud images of subsea assets and environments. By combining the 3D laser data with precise underwater acoustic and inertial navigation information, it is now possible to generate centimetre resolution engineering models from which accurate measurements can be instantaneously and repeatably captured.
This video clip shows a segment of an underwater benthic habitat mapping survey using a Savante Underwater Laser Profiler mounted on a towed sledge vehicle. Sledge-based "ground-truth" habitat mapping surveys are often conducted for reasons of cost and simplicity and at velocities of up to 2knots along the seafloor. Vehicles are often lowered by rope from fishing vessels of opportunity and guided using simple compass, GPS navigational tools and actually very little else. A real change from the world of 200 million dollar oil and gas construction support vessels and hydroacoustic position referencing systems. Environmental insight into the condition of vast areas of the seabed have been made possible through the economics of this low-cost means of survey. As demonstrated in this video cli...
Every time you visit a web page or send an email, data is being sent and received through an intricate cable system that stretches around the globe. Since the 1850s, we've been laying cables across oceans to become better connected. Today, there are hundreds of thousands of miles of fiber optic cables constantly transmitting data between nations.

Torbjørn Goa wrote and produced this case study video for subsea navigation technology specialist Nortek. This video shows how researchers at the Norwegian University of Science and Technology (NTNU) used an instrument from Nortek to solve subsea mapping challenges. The video was made in collaboration with film production company AVIA Produksjon in Oslo, Norway.
http://www.businessinsider.com/animated-map-global-fiber-optic-internet-cables-2015-9 ---- 99% of international data is transmitted by wires at the bottom of the ocean called submarine communications cables. In total, they are hundreds of thousands of miles long and can be as deep as Everest Is tall. The cables are installed by special boats called cable-layers. It’s more than a matter of dropping wires with anvils attached to them—the cables must generally be run across flat surfaces of the ocean floor, and care is taken to avoid coral reefs, sunken ships, fish beds, and other ecological habitats and general obstructions. The diameter of a shallow water cable is about the same as a soda can, while deep water cables are much thinner—about the size of a Magic Marker. The size difference is ...
The J2 ROV operated tool changer is designed to revolutionise the way ROV tooling is used subsea, by allowing the ROV to connect with tooling on the seabed, providing vast cost savings for operators. The tool changer features: -Depth-rated to 5000 meters -Easy to maintain -Easy to mate and de-mate -Zero-leak capabilities See more and enquire about the tool changer on the J2 website: http://www.j2subsea.com/

Many network owners have invested heavily in state-of-the-art GIS platforms but end up filling them with unreliable digital data, often converted at great cost from old analog maps. Whether due to stricter industry regulations or changing network risk guidelines, the pressure to improve the quality of network as-built data is increasing. Affordable and efficient technologies are required to meet this need. Reduct focuses solely on doing just that. It has developed the DuctRunnerTM technology, an innovative modular mapping system. Today, a range of Pipeline Mapping Systems and Services are on offer that meet the market's demand for accurate and efficient pipeline mapping.

On July 15th,1942, the German U-boat 576 was sunk off the coast of North Carolina. Today, you can see an amazing 3D image of U-576 in the form of processed point cloud. This was created using a revolutionary new dynamic underwater mobile scanning technique using lasers. Using Sonardyne’s LBL acoustic positioning technology, coupled with SPRINT INS, Syrinx Doppler navigation and 2G Robotics’ ULS-500 laser mounted to a manned submersible, NOAA were able to fly over the sunken U-boat whilst simultaneously taking continuous laser scans.
