In the normal operation of an offshore wind turbine, bolts can loosen due to long-term operation and exposure to vibration; however, a proposed device could help detect loosened bolts before extensive damage can occur.
By Wang Fei and Qu Jun

For the problem of loosened bolts in the long-term operation of an offshore wind turbine, we proposed a device to detect loosened bolts. The device included a vibration sensor, a signal receiver and transmitter, a CCD sensor, a data analyzer, power supply, a communication line, and a power supply line. The combination of a data […]

With offshore wind development accelerating globally, Lidar is reducing uncertainties and meeting many previously unmet needs for offshore developers and operators throughout each stage of a project.

Offshore wind development is gaining momentum around the globe. Expected to constitute more than 20 percent of total wind energy installations by 2025, offshore wind is growing in both near-shore environments and in deeper waters farther from the coast. The United States, supported by a combination of federal incentives and state-level targets, is witnessing strong […]
