48 st / September 2017 Magnetic Crawler for Tank Inspection Petrospect Inspection Est. in Saudi Arabia chose Inuktun's MaggUT Ma- rine robotic vehicle to perform remote visual inspections and ultrasonic test- ing and to clean away the heavy sedi- ment often found on the bottom of steel storage tanks. Inuktun delivered a custom solution miniature magnetic crawler that combined a heavy-duty cleaning brush with a Crystal Cam Sapphire inspection camera and a standard Olympus ultrasonic thickness gauge. AELCloud Runs Analysis, Simulation for Fugro The subsea engineering analysis consultancy AgileTek has completed the first use of its AELCloud system on a project for Fugro. The work required a substantial number of simulations of subsea power cable installation opera- tions to be performed to verify proce- dures, component sizes and weather windows. Some of the results were re- quired at critical milestones within the larger project, and AELCloud allowed AgileTek to scale server capacity on demand to meet these deadlines. AELCloud is an online platform de- veloped by AgileTek which runs analy- sis and simulations on both cloud and the client's local servers. It drastically reduces the time traditionally needed to run simulations. On this subsea installation project alone, AgileTek ran approximately 27,000 OrcaFlex simulations which equated to around 57,000 hours, or just over six years of simulation time. AELCloud processed a total of 1.5 billion data points for critical metrics in the system. 3D Optical Models Underwater Through New Imaging System The Advanced Imaging and Visual- ization Laboratory (AIVL) at the Woods Hole Oceanographic Institution (WHOI) has developed a new multi- function underwater imaging system capable of generating ultrahigh-defi- nition television (UHDTV) video, 2D mosaic imaging and 3D optical models of seafloor objects and environments. The technology is being field tested on several submerged shipwreck sites in both the U.S. and Europe. The tech- nology will enable rapid production of 3D optical volumetric models of the seafloor—images that scientists can spin to view from all sides and zoom in on to visually explore around and inside objects or ocean environments. These models are helping to transform the way scientists examine study areas. Developed by AIVL in collaboration with the National Park Services Sub- merged Resources Group and Marine Imaging Technologies, the near-milli- meter accurate 3D models are built us- ing digital optical imagery, rather than lasers. EchoBoat Surveys Levees in California The Seafloor Systems EchoBoat USV is on the job for the California Depart- ment of Water Resources and R.E.Y. Engineers surveying the fragile delta region levee system. The EchoBoat is integrated with a Norbit iWBMSc mul- tibeam echosounder and a Velodyne Puck LiDAR sensor.
