Josh Gates from the Travel Channel series Expedition Unknown travels to his ancestral home of Great Britain to explore the origins of Stonehenge. From high in the air to deep under the sea, he finds an unexpected network of monuments that could have inspired one of history's most mystical locations.

This video shows how Teledyne BlueViews 3D Multibeam Scanning Sonars are used to find and map what is believed to be the original inspiration for Stonehenge.

BlueView Arc 3D Bridge Inspection

Mon, 16 Jan 2017 11:47:26 GMT

The data for this bridge inpsection was collected from a tripod deployed BV5000 system from a small boat. Scans were conducted at 3 adjacent locations to provide the final large arae data set delivered to the client.

Quote: John F. Sawyer, Vice President, Arc Surveying & Mapping, Inc.

"We are especially interested in the interface of the seafloor and underwater structures. Your demonstration of the Blueview sonar - mounted on a tripod and lowered below the water at locations not accessible by our survey boat - proved to be the answer to complete bottom coverage on our bridge scour projects. Our clients are very pleased with the results."

BlueView’s BV5000 takes the guess work out of bridge inspection and maintenance projects by provide near immediate 3D renderings of structures, even in low visibility conditions. Up to now, there has not been many options other sending divers and ROVs in to inspect large areas of bridge footers for potential problems. These methods become extremely difficult when visibility is reduced. The BV5000 system provides fast high-quality results in almost any condition.

BlueView BV5000 Underwater Inspection of an Oil Platform

Mon, 16 Jan 2017 11:44:01 GMT

3D Rig Visualization

This sonar imagery was taken as part of an offshore oil rig decommissioning project. The unique aspect of this job was that other than the 3D mechanical scanning sonar and ROV, no other survey sensors or equipment was used to gather the 3D sonar data. One operator was flown to the site with the BlueView Technologies BV5000 3D mechanical scanning sonar and a laptop. The sonar and laptop were integrated on-site with a spare ROV early on the first day of work. The 3D sonar data was then gathered over a period of 16 hours without affecting the ongoing decommissioning operation. Post processing of the sonar data to generate the mosaic 3D imagery took a total of 20 hours and was done “on-shore” by the same operator using Leica Cyclone software.

ROV Based Culvert Inspection

Mon, 16 Jan 2017 11:21:02 GMT

Modern Solution for a Tough Job

In many parts of the world, particularly near large bodies of water, culverts make up a large portion of a city's waterway infrastructure These culverts are responsible for safely moving water under and around other structures like buildings and roadways. When these passages get clogged with debris, they can pose a serious risk to property and human life. Just a few of the consequences of poorly maintained culverts are increased flood levels, flow diversion out of streams, overland flood paths, and scouring of overtopped embankments.

Culverts with a diameter of 6m and smaller are more prone to capturing debris and should be inspected regularly and cleared if needed. These culverts can also be more difficult to inspect because of their size and the environments they are typically found in. The confined space aspect makes diving such passages dangerous and time consuming. In addition, the environmental aspects can vary between rushing torrents of water and stagnant black water, both of which add significantly to the risks involved with sending a diver in.

With today's modern ROV's and multibeam imaging sonar "acoustic cameras", these once dangerous jobs can be performed in a safe controlled manner. They can also be completed faster and more thoroughly than ever before. Using the ROV's imaging sonar to quickly navigate and search an culvert, then the ROV's camera to visually inspect for debris debris structural damage, an operator can quickly inspect a culvert from the a mobile control station well out of harms way.

BlueView 3D Scan Drydock Gate

Mon, 16 Jan 2017 10:49:58 GMT

3D Inspections and Surveys

This 3D sonar imagery was taken during a hands-on demo held by BlueView and Seatronics in Aberdeen, Scotland. The high resolution imagery shows the advantages of the BV5000 when used as an inspection/survey aid. In this example, the BV5000 was lowered to the harbor bottom at four (4) different locations in front of a dry dock. A total of (4) 3D scans were captured in less than an hour of total collection time and then combined using Cyclone software to achieve a complete 3D point cloud of the dry-dock gate structure. One can clearly see the structure of the dry dock gate, the pilings, the slope of the bottom up to the gate and the sharp drop in elevation to the right of the gate. Additionally, you can see the depressions in the harbor floor just in front of the dry dock that are created when the gate folds down into the mud. In low or zero visibility conditions, BlueView's easy to obtain 3D imagery is ideal for inspecting and surveying underwater structures.

AUV Gap Fill Sonar

Tue, 20 Dec 2016 15:53:52 GMT

The video clip demonstrates how BlueView’s 3D MicroBathymetry Sensor was adapted byHydroid, Inc. as part of an Atlas Elektronic UK project for the UK Ministry of Defence. TheBlueView MB2250 was integrated into a Hydroid REMUS 100 UUV section to provide highresolution 2D and 3D imagery filling the nadir gap typically associated with traditional sidescan systems. The Atlas Elektronik UK Classiphi software fuses the the BlueView gap-fillingsonar data with the side scan sonar data gathered by the REMUS 100 to provide Seamlessimagery across the entire swath. The fused sonar imagery results in wider area coverage todramatically improve coverage rates and reduce mission times. Further, the high-resolution3D data enables classification on targets of interest. The UK MOD has now contracted withHydroid to equip a Royal Navy REMUS 100 vehicle with BlueView’s MB2250 sonar.

BlueView Spool Piece Metrology Testing

Tue, 20 Dec 2016 15:53:39 GMT

This sonar imagery was taken during spool piece metrology testing in Peterhead Scotland. Pipe Flanges where positioned around an empty drydock, a ground based survey was performed, the drydock was then flooded, and a 3D acoustic scan was made of the site. Using standard laser scanning software packages, piping components were modeled to the point cloud data, and engineering CAD drawings of the scene were produced. Not only is this method faster, it provides much more information about the space between the flange ends for project planning.

Dam Draft Tubes Flyby

Mon, 19 Dec 2016 14:20:32 GMT

The video clip utilizes actual 3D data gathered with the BV5000 to show the results of aninspection of an upriver dam’s outflow tubes. There were several unique aspects to thisproject, first the remote location of the dam limited access to the site and the highportability of the BV5000 was the perfect solution. Second the project called for aninspection of each of the tubes from threshold back to the control gate doors, a distance ofmore than 25 m (82 ft.) which was easily met by the 30 m (98 ft.) range of the BV5000.Finally, water clarity levels were low and operators needed to verify that there were nodebris deposits that would affect outflow when the control doors were opened, here the high-resolution acoustic technology of the BV5000 made the job easy. The total data gatheringtime was less than 5 hours and processing took 8 hours for a total of 13 hours.
