10 ST | June 2018 www.sea-technology.com Echoscope 4G Surface The Future of Visualization, Mapping Sonars By Richard Adams T he uncertainty that lies below the surface of the sea provides a number of industries with incredible challenges when conducting their daily busi- ness. From offshore structure installation and inspection to the defense of ports and construction of national power generation assets, all subsea industries are plagued with a dynamic set of problems they must address. The industry standard technology that is utilized for underwater inspection is the multibeam sonar, which was introduced to the market around 20 years ago. At the time, the multibeam was revolutionary because it could generate clearer images of the underwater environment than the precursor technology, the single beam. The multibeam, however, has limitations as its outputs require post-processing to render useful 3D images of the area being inspected and cannot image moving objects. Many subsea applications require technology that can facilitate real-time 3D decision making of both static and dynamic operations. Background Coda Octopus Products Ltd. has recognized this market requirement and has been at the forefront of marine survey operations for nearly 25 years. The compa- ny started as a pioneer of digital acquisition and processing for geophysical sur- vey, and this innovation and emphasis on research and development (R&D) has characterized the company ever since. Coda Octopus has continued to lead the geophysical acquisition and processing market with its GeoSurvey, DA and Survey Engine product ranges. In addition, it has developed a range of patent- ed real-time 3D volumetric sonar systems marketed under the brand name of Echoscope. This technology allows the user to generate a real-time 3D image of the underwater environment, even with low- or zero-visibility conditions, and has been successfully used on a wide variety of complex subsea projects and operations across the globe, including in oil and gas applications, breakwater construction, asset placements and landings, port and harbor security, defense, mining and diving applications. Our real-time 3D and geophysical product ranges are complemented by GNSS-aided inertial navigation systems. The F180 series, for example, has a proven track record in the marine survey industry for accuracy and reliability and is found on survey vessels across the world. Our third generation of real-time 3D sonar products includes the standard Echoscope and Echoscope C500. They have a standard depth rating of 600 m and can be supplied with 3,000-m ratings; we also have the capability to take these down to 6,000 m on request. We continue to innovate and develop new application products within the real-time 3D sonar arena. All of our real-time 3D sonars transmit a large volumetric pulse of sound energy that generates typically more than 16,000 beams for every acoustic transmission or "ping."
