3D Laser Survey in Offshore Ghana

ADUS DeepOcean and DeepOcean Ghana have recently completed a deepwater subsea 3D laser survey in offshore Ghana, off the west coast of Africa, for Tullow Oil. This is the first extensive commercial survey of its kind, heralding high-resolution, cost-effective data acquisition in subsea environments. The survey operations covered 12 drill centre locations and a total of 27 metrologies in water depths of between 800 and 1,800 metres. This has set new benchmarks for high-resolution contextual 3D surveys whilst proving an alternative and rapid ‘contactless’ solution to conventional metrology surveys. The dynamic laser survey solution, from a moving ROV, comprised a... (read more)

Tetra Tech Buys 3D Mechanical Scanning Sonar

Global surveying company Tetra Tech has purchased a BV5000-1350 3D mechanical scanning sonar. This system produces high-resolution 3D point cloud imagery of scanned areas such as bridges, dams, ports and harbours. The BV5000 is designed to be easily set up, deployed and operated to provide a turnkey 3D solution. The BV5000 compliments Tetra Tech’s current suite of survey equipment. The high-resolution data and the perspective the deployment tripod provides will help to capture images of areas that are difficult to get to, scour/undercut and vertical structures. It will allow the company to support a broad range of customers for underwater... (read more)

Domed Scanning Sonar by Kongsberg Ready for Delivery

Kongsberg Mesotech introduced the Clariscan domed scanning sonar earlier this year. The Clariscan sonar is now ready for delivery to customers, as of 30 June 2016. With the Clariscan domed scanning sonar, Kongsberg Mesotech has significantly improved sonar performance with a patented lens that refocuses the acoustic energy, producing images that are much clearer. These images were all obtained during deep water testing in the Gulf of Mexico. The three images below show the Clariscan sonar on the left, compared to a standard 1171 domed sonar with composite transducer on right. The two sonar heads were mounted on the same ROV...

3D Mobile Seabed Mapping Using Underwater Laser Technology

Sonardyne has used 2G Robotics’ underwater laser scanning technology to dynamically scan and map the seabed in Monterey Bay, California, USA. The high-resolution deepwater mapping of Sur Ridge was performed using 2G Robotics’ ULS-500 underwater laser scanner mounted on an ROV. For the deployment, the ROV was equipped and navigated using SPRINT 700 AAINS, 6G Wideband Syrinx DVL (600kHz), ROV Nav 6 LBL transceiver and a precision pressure sensor. EIVA’s hydrographic survey and navigation software was integrated with the ULS-500 using EIVA’s dedicated driver for 2G Robotics’ systems to facilitate with data capturing and post-processing.  Sonardyne noted that laser mobile mapping...

Underwater Laser Scanners for Sediment Transport and Scour Analysis

Genex Systems, USA, has trialled and the purchased a 2G Robotics' ULS-100 underwater laser scanner. The objective of the trials was to test the capabilities of the ULS-100 for bridge scour experiments and sediment transport analysis. The trials were conducted at the TFHRC J. Sterling Jones Hydraulics Research Laboratory. 2G Robotics’ ULS line of underwater laser systems produce true-scale high-resolution 3D models of underwater structures and environments in real time. These 3D models function as dimensional records and serve as reliable references from which to obtain accurate measurements and information. Both stationary and dynamic scans were performed with the ULS-100.... (read more)

ULS-500 Underwater Laser Scanner Interface for QINSy

The 2G Robotics ULS-500 underwater laser scanner is compatible with QPS’s QINSy. Recently, 2G Robotics performed a structure inspection demonstration with a customer to validate the ease of operation and demonstrate the capabilities of the ULS-500 system. To collect the data in profile mode, the ULS-500 published data in LAS format into QINSy. QINSy was interfaced directly to ROV sensors (high-end INS, Doppler) and the ULS-500 to correct for ROV altitude in real time and to georeference using INS position updates aided by Doppler in order to position the ULS-500 data and build a complete 3D model. In this trial,... (read more)

CDL to Develop Holographic Laser System (5-3-2004)

CDL are leading a 3 year Link/OSDA funded program to develop a subsea holographic laser based on the advanced research conducted by an academic team headed by Dr John Watson of Aberdeen University. Laser expertise will be provided by Elforlight UK Ltd. Digital Holography uses an electronic camera usually a CCD, to record data and images within a sample volume instead of using photographic plates or film. The sample is then reconstructed onto computer through specially developed software and provides the operator with a real-time 3-D computer model up to 3000 cm3. e-holocam will measure particles with an accuracy of...
