kHz. Secondly, passive acoustic receivers, like C-PODs and SoundTraps will listen for cetaceans. “C-PODs monitor the presence and activity of toothed cetaceans by detecting and analysing trains of echolocation clicks,” explained Birnie-Gauvin. “With the help of an automated data analysis software, C-PODs can identify dolphins, porpoises and echolocating cetaceans (except sperm whales) from quite a distance. SoundTraps are underwater sound recorders that can listen for sounds made by cetaceans but also noise pollution, including boating activity, seismic surveys.”“Fish and

targets. When combined with navigational data, it is possible to deliver real-time geo-corrected laser models, and consistent images across incredibly long surveys. This uniformity produces wide area consistent image mosaics without variations in quality from image to image. Adding onboard analysis software, like EIVA’s Onboard Deep Learning, enables the automated detection of pipeline defects and features, to drastically reduce analysis time.A color image mosaic of subsea pipeline.

design that comes fully calibrated and only requires mounting and connection to the vehicle's auxiliary power and communication channels. The 2G Robotics ViewLS Data Module enables users to combine navigation and laser data, and extract targets of interest into third party point cloud analysis software.The skid is neutrally buoyant to maintain vehicle maneuverability and includes the 2G ULS-500 Micro laser scanner, iXblue’s Rovins Nano Inertial Navigation System, Nortek’s DVL1000, and Valeport Depth Sensor to deliver high accuracy geo-referenced laser inspections.

Engineering Better Propulsion
as you do for large propellers, but it’s actually more demanding,” MacPherson said. “Small propellers are influenced to a greater extent by viscous and frictional issues, so manufacturing tolerances have to be tighter.”The company’s flagship resistance and propulsion analysis software, NavCad, aids in the sizing and selection of an appropriate thruster or propeller. The software can estimate vehicle drag and quantify the impact on propulsion power from the addition of control surfaces, antenna and other appendages. NavCad can also be used to size propellers and predict the
Don't Let the Ocean Knock You Down
But sometimes this isn’t good enough. This article looks at getting more precise with mooring analysis using numerical modeling software designed for ocean engineers. Numerical modeling software for single point moorings has come a long way in recent years. Finite-element based cable analysis software has been tested and developed by oceanographic institutions and ocean engineers for various purposes (towed bodies, ROVs, moorings, etc). However, its use has been typically limited to a few advanced numerical modeling specialists who had both the expertise and patience to wade through the
JIP Validates DNV GL's Helica Software
A joint industry project run by DNV GL has replicated stresses measured in an umbilical subjected to tension and bending in full-scale tests, further validating the accuracy of the analysis software Helica. DNV GL’s Helica can analyse thousands of simulations in a matter of minutes, improving engineering efficiency and significantly reducing design cost. Helica software for analysis of umbilicals and flexible pipes Subsea engineers calculate stresses in umbilicals and flexible pipes using software to ensure that individual components will not fail. Such failures could lead to costly production

The C-I MUNINs have a fast charge system and data download facility designed to maximize productivity and minimize down-time between dives. They are also supplied with the Kongsberg Maritime Reflection AUV post-mission analysis software. In-mission supervision including real-time data transmission and position aiding is provided by Kongsberg Maritime’s HiPAP acoustic system. The best position solution available is calculated by NavLab navigation post processing software
Things to Know When Choosing a Water Level Logger
against NIST-traceable standards. Some companies offer NIST-traceable calibration certificates as verification of the accuracy of each logger. 3. Software Features That Really Matter Just as water level loggers can vary considerably from model to model, so too can the graphing and analysis software or app that accompanies them. From a general standpoint, it’s a good idea to look for something that’s highly intuitive so that the learning curve is minimal. You’ll also want to be able to quickly and easily perform tasks such as configuring loggers, and offloading, graphing
