The scale, shape, and height of wind turbines makes them challenging subjects for inspectors. Wind turbines are throughly tested before installation, however as they face wear and tear and weathering forces like lightning strikes, high winds, and other hazards throughout their working life, inspectors must use nondestructive testing methods to monitor the integrity each facet of [...]

Carbon fibers serve as a building block of fiberglass, a material used in many different structures from aerospace vessels, to wind turbine blades, to sports equipment. First created in the 1950s, carbon fibers act as a popular material in the aerospace industry because they weigh significantly less than titanium or aluminum and reduce fuel costs [...]

Underwater structures pose unique challenges to inspectors. Many testing methods inspect these structures from a single, accessible testing point by way of technology such as Long Range Ultrasonic Testing. However, there is another method of inspecting and cleaning pipes from the inside instead of a single set point called "pigging." "Pigs" are devices that [...]

Inspecting helicopter rotor blades comes with challenges as blades are manufactured with different internal and external materials. However, the early detection of defects such as fatigue cracks means the difference between life and death for helicopter operators and passengers, as has been evidenced by several helicopter crashes in recent years. November 2011 saw a fatal [...]
