DAM OUTFLOW TUBES INSPECTION

Mon, 16 Jan 2017 13:52:59 GMT

Underwater infrastructures worldwide need to be inspected regularly for problems caused by corrosion, scour, undercut, impact damage and debris. Diving engineers will typically inspect these structures visually when water conditions allow, and by hand when working in murky water. Divers also regularly need to work in possibly unsafe environments without knowing what the area looks like prior to getting in the water. Sonar on the other hand, can produce high accuracy 2D and 3D structure and environmental data in even zero visibility water conditions. For these reasons, sonar is quickly becoming the tool of choice for underwater inspection of bridge structures to enhance traditional inspection methods.

Teledyne BlueView's 2D imaging sonar is designed for high resolution imaging that provides detailed pictures in any water condition. Imaging sonar is well suited for general inspections, environment evaluations and real time diver monitoring. They can be mounted on poles, small vessels, tripods, ROVs, and even diver hand held systems. They have the ability to image areas around bridge footers, ports, harbors, dams, as well as identify damage, debris and suspect areas which may require continued monitoring.

Teledyne BlueView's 3D mechanical scanning sonar is lightweight and easily deployed off the side of a bridge or from a small vessel to collect 3D point cloud data. The high resolution point cloud data provides valuable information on underwater bridge structures such as damaged locations, undercut measurements, depth soundings and other standard inspection information. These high quality and high density data sets allow the user to make detailed analysis interpretation, and measurements of the inspection area which becomes particularly useful as some diving inspection methods are prone to human error.

With the ability to inspect with the 2D system and measure with the 3D system, Teledyne BlueView sonar is very complimentary tools. Having the capability to record current conditions and compare with previous and future inspections enhances nearly any type of underwater inspection operation, increases the value of deliverables, and improves the safety of inspection divers by raising their situational awareness. These are some of the many advantages of utilizing underwater imaging equipment.

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.

BlueView Spool Piece Metrology

Tue, 20 Dec 2016 15:53:53 GMT

This movie illustrates a novel new underwater measurement system that combines a new acoustic 3D scanning tool underwater combined with 3D scanning laser above water. Quick to deploy and accurate enough to calculate the required angular and range measurements, the BlueView 3D Scanning Multibeam Sonar creates more than just a table of discrete measurement values. Rather, it produces a rich 3D point cloud with millions of data point measurement. This data can be rendered to provide a clear 3D picture of preinstalled assets and their surrounding topography from which accurate range and angular measurements can be quickly and easily be made. The resulting 3D model can also be used as a full as-built/as-found record beneficial for aiding future intervention based work.

A non-intrusive tool, the principle of operation is similar to that of 3D topographic laser scanning, a technology used by the terrestrial survey industry for many years. Now for the first time an acoustic-based counterpart has been developed to carry out similar work underwater. In fact, the data produced by this acoustic system is so similar to optical laser data that it is very successfully processed with optical laser processing software. This enables full access to a wide range of pre-existing software tools as well as unique applications combining laser and acoustic data.

Following a series of dry-dock trials by global subsea electronics supplier, Seatronics to help prove the concept and benchmark accuracies, adoptive support from Technip and input from survey company Star Net Geomaticshave led to this device being quickly moved from the lab to open water operations with several successfully projects now completed with major O&G companies including Total E&P UK Ltd, Talisman Energy (UK) Ltd and Fairfield Energy.

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.

Tue, 20 Dec 2016 15:53:39 GMT

Seattle, WA -- The first high-resolution, 3D digital model of a perfectly preserved, 100-year-old steamboat was unveiled today. Using a new sonar scanning system provided by BlueView Technologies and OceanGate, the survey, which would have taken years to complete using traditional underwater archaeology techniques, took only days.

Images of the A.J. Goddard, a famous sternwheeler "ghost shipwreck" from the Klondike Gold Rush, are the first 3D views of the frontier-era steamer that disappeared in a winter storm in October 1901. Only two members of the five-man crew survived. Goddard's location remained a mystery for 107 years until it was discovered in 2008 by the Institute of Nautical Archaeology (INA) at the edge of Lake Laberge, in the subarctic wilderness of Canada's Yukon.

INA partnered with OceanGate and BlueView Technologies on an expedition to create a 3D survey of the wreck, recently designated as a Yukon Historic Site under the Historic Resources Act. The new BlueView scanning system, BlueView BV5000, allows archaeologists to easily scan underwater areas and complex objects significantly advancing researchers' capabilities to complete archaeological surveys of complex targets.

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.
