3D Visualisations Generated by Underwater Laser Scanning

2G Robotics
2G Robotics is located in Waterloo, Ontario, Canada. The company’s underwater laser scanners generate real-time 3D models of subsea assets and environments from which submillimetre measurements can instantaneously and repeatably be captured. These models provide the precision and accuracy needed for detecting and assessing damage, developing design and repair plans, and performing maintenance and installations. Jason Gillham, founder and CEO, has always had a passion for marine technology. He founded 2G Robotics in 2007 after completing his studies in Mechanical Engineering at the University of Waterloo. Gillham possesses over ten years of experience in the development of marine technology, the... (read more)

Sonavision Launch TITAN Scanning Sonar

Sonavision Ltd announce the arrival of the long range sonar TITAN, the latest member of the Sonavision Scanning Sonar family. Although, measuring only 226mm by 90mm, the TITAN is capable of ranges up to 300m and is the only sonar of its size with the performance of a high-resolution sonar. TITAN uses a special wideband 1:3 Piezo Composite Transducer. Benefits of using composite transducers are enhanced beam control, optimisation of transmit and receive and suppressed side-lobes to reduce false returns. TITAN is available as a 500kHz sonar (standard) with options for different frequencies and ranges. The transducer uses separate transmit... (read more)

Scanning Sonars Assist Underwater Searches

Scanning sonar is fast becoming the tool of choice for underwater search operations by a diverse group such as public safety dive teams, universities and commercial diving companies. Reasons for the popularity of the sonar include its effectiveness and cost, which is only a fraction of a side-scan sonar.     Scanning sonars are in demand because they create a picture of the underwater environment regardless of water clarity. Although these sonars lack the long range and very high resolution of side scan, they still give a larger and better picture of the underwater environment compared to an underwater camera...

Nuclear Underwater Laser Scanner

Newton Labs has developed and deployed a laser scanning product specifically designed to operate underwater, in-vessel, within either PWR or BWR reactors. The device, the NM200UW Nuclear Underwater Laser Scanner, designed in partnership with a major US nuclear utility, produces a point-cloud output so detailed that when utilised with industry-standard three-dimensional software a full measurable CAD model can be generated.     “This is a very exciting new product for the nuclear industry.” stated John W. Bramblet, president and CEO of Newton. “The need has existed for some time to be able to produce precise measurements and dimensions in-vessel. The... (read more)

Hydrographic Airborne Laser Scanner

RIEGL introduced the VQ-820-G Hydrographic Airborne Laser Scanner in September 2011. This device has been specially designed for combined land and hydrographic airborne surveying. The high-accuracy ranging is based on echo digitisation and online waveform processing with multiple target capability.   Laser range measurements for high-resolution surveying of underwater topography, the bottom of shallow waters and riverbeds, are carried out with a narrow, visible green laser beam at 532nm, emitted from a powerful laser source. Depending on water turbidity, this laser wavelength allows measuring into water.   (read more)

Black Laser Learning

Enhancing formal instruction
Traditionally hydrographic/marine geophysical training has been conducted by equipment manufacturers or educational institutions. As a long time technical instructor for various equipment manufacturers Vince Capone, founder of Black Laser Learning saw a gap in the hydrographic training market. There was a need for economical training conforming to the client's schedule. Once Black Laser Learning identified the training need, there was considerable debate over how best to present the information? There existed a small but high quality library of written reference materials. We did not want to duplicate those materials and also develop a product go beyond the written text with... (read more)

Scanning Data Integrated in PDS2000

Fusing data sets from multiple sensors is a demanding requirements being seen more and more frequently in client specifications, typically combining photogrammetry or laser data with multibeam sonar data to create a seamless image of structures above and below the waterline. RESON have now prepared the PDS2000 software package to combine data under the waterline with data above the waterline to show breakwaters and harbour walls. Data from the laser scanners are shown in real time, and are fully corrected for heave, roll, pitch, heading and position. Together with the multibeam data, crisp laser images are presented to the operator... (read more)

Scanning Sonar for Poor Visibility Underwater Environments

US-based Blue Robotics is launching the Ping360 Scanning Sonar, which offers small ROVs the ability to navigate in low visibility water conditions. The Ping360 is a mechanical scanning sonar – it uses a small acoustic transducer mounted on a motor that rotates it in one-degree increments. As it rotates, it transmits and receives acoustic pulses to build a 360-degree image of the surroundings. This is similar to laser scanners and LIDARs used for ground robotics and autonomous cars, but using sound waves instead of light. Maximum Water Depth of 300 Metres When mounted on a remotely operated underwater vehicle (ROV),... (read more)

Scanning Sonar Delivered to Tetis Group

EofE Ultrasonics, Korea, reports it has delivered ten sets of scanning sonar Echologger MRS900 to Tetis Group. The 2000m-rated ultra-compact scanning sonar will be installed on Tetis' ROVs. EofE Ultrasonics said it demonstrates that performance and compactness of the device are outstanding and ideally suitable for navigation and search operation of the vehicles. MRS900 is optimally design for underwater vehicles with high scanning speed and high resolution images. EofE Ultrasonics believe more underwater vehicles will adopt the high resolution scanning sonar RS900 as well as MRS900 for performance especially when related to the prices. (read more)
