New Tech for Wind Blade Inspections

a lawn. On-board cameras provide real-time, high-fidelity images to detect surface damage, as well as small demarcations that may signal larger, subsurface damage. While moving, the robot also uses a wand to scan the blade for damage using phased array ultrasonic imaging.The scanner works much like the ultrasound machines used by doctors to see inside bodies, except in this case it detects internal damage to blades by sending back a series of signals. Changes in these ultrasonic signatures can be automatically analyzed to indicate damage.Sandia Senior Scientist and robotic crawler project lead Dennis Roach

Naviera Tramarsa Adds Another ROV

the Cougar XT will expand and improve its ability to inspect, clean and perform non-destructive testing.Their Cougar XT comes with a high definition enhanced monochrome camera and a Kongsberg color zoom camera, a Tritech Super SeaKing sonar, dual five-function manipulator, cleaning brush tool, CYGNUS ultrasound thickness gauge and pipe cable tracker.The Cougar’s compact footprint makes it easy to mobilize and, despite its size, still provides the power and maneuverability to handle a wide range of heavy tooling and sensors, the manufacturer said. The vehicle features six thrusters interfaced with

on an ROV, which could find locate defects before the more targeted Oceaneering tool is used.As part of the same project, Uniper and Next Geosolutions are developing subsea monopile and grout inspection technologies. Working with British Geological Survey, Uniper has offered a tool to do low frequency ultrasound inspection at the wavelength of the grout thickness. Spectra reflections from the ultrasound can be interpreted to show gaps or disbandment in the grout.Next Geosolutions, as part of a consortium with Hydrasun and Ashtead, is also developing a tool to perform subsea grout inspection using wideband

ranging from mobile solution to cloud applications. For instance, the real time decompression management software DepthMonitor is a product to be used with the INNOVASUB Divephone case rated to 500 ft.; The Frameanalyser software is a signal processing tool to detect post decompression bubbles from ultrasound recordings. The SSK (Supervisor SideKick) is a tool for diving supervisor to organize their dives and to maintain small and medium scale databases of equipment and divers. Its electronic hardware team has patents on converting the analog panels to digital and for monitoring breathing. Its electronic

Channel Technologies Acquires H.C. Materials

an active board member. Other terms of the transaction were not disclosed. CTG is a portfolio company of Blue Wolf Capital Fund II, L.P. The acquisition enables CTG to capitalize on HCM’s global recognition and leadership in the piezoelectric single-crystal arena, especially within the medical ultrasound market. It also consolidates CTG’s position as a global leader in the ceramic-based piezoelectric industry. HCM’s operations will remain in its current Bolingbrook, Illinois location. CTG will continue to invest in research and development into next-generation applications for piezoelect

delivers groundbreaking underwater vision and measurement systems to the maritime community.  Dr. Thompson has secured and managed numerous commercial funding rounds and R&D grants as well as developed technologies leading to multiple product developments in fields of Navy systems, medical ultrasound, consumer products, and marine electronics.  

Subsea Testing & Training Center in Demand

where a photographer dived with one of the classes and used students to test the equipment and act as models for promotional shots.The new metal thickness meter, the ‘Cygnus Dive’, is the latest development from the company.  The device measures the thickness of a material, using ultrasound, to determine if corrosion or erosion has taken place over time.   It replaces the Underwater Gauge, which is currently used on the Non-destructive Testing (NDT) Course at The Underwater Centre, and will be the first ever subsea Ultrasonic Thickness Gauge (UTG) to be wrist mounted.
