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...
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 ...

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.
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.

I wanted to take a shot at turning an overland map into and underwater sunken ruin. It's actually pretty easy, so I put together a quick video that walks through the steps.
An overview of the field survey capabilities using subsea LiDAR system from 3D at Depth
An overview of subsea LiDAR with four project data sets
SPRINT-NAV combines our class-leading inertial and Doppler velocity log technologies with a high accuracy pressure sensor in a 4,000 metre rated housing that's just 395 millimetres tall. The result? An all-in-one subsea navigation system for your ROV or AUV that’s sure to save you vessel time and lower your survey costs.
Boaters rely on NOAA’s nautical charts for depth measurements so they don’t accidently ground on sandbars or other underwater obstructions. NOAA gets these measurements by using hydrographic survey technology from onboard ships and smaller boats. Sometimes, though, the water may be too shallow for safe operation of the survey vessels. Lidar systems systems can be used in some cases, but that technology doesn’t work well in murky water. NOAA is experimenting with autonomous surface vehicles (ASV) to reach and survey the shallowest of areas found on nautical charts. ASVs, which operate at the surface of water, can measure depths in areas as shallow as one foot, reaching areas close to piers, pilings, and the shoreline.

We are determined to create reliable, cutting edge technologies for exploring, mapping and monitoring the subsea environment with great precision.
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.

Sonomatic subsea inspection solutions include delivery of a wide range of advanced techniques, either diver or ROV deployed. - Diver deployed inspection solutions - ROV deployed inspection solutions - Deep water inspections - Inspection through coatings - Pipelines - Structures - ROV tooling - Accurate automated corrosion mapping
SUBSEA PEC is Impresub’s brand name for the complete solution technology ready for the site implementation. It provides automated sectional scanning of the complete pipe segment and map corrosion status readings around the entire pipe surface. The PEC physics integrated into the SUBSEA PEC system also secures very important and key operational flexibility; although the wall thickness readings are taken on the pipeline outer surface, it requires no special pre-treatment to the existing pipeline coating, concrete protection shell or marine growth for achieving the accurate wall thickness readings on the steel pipeline. Hence, SUBSEA PEC solution is geared to work silently without disruption of the regular pipeline exploitation. SUBSEA ROV-PEC is a system customized and completely independen...
