Health monitoring of offshore energy generating towers
Keywords: Health monitoring; offshore; wind and wave energy; remote sensors.
Renewable energy is the only panacea for the rising demand for energy and the non-sustainability of fossil fuels. Wind and wave energy are two potential non-renewable energy sources, which will be harnessed on a much larger scale in the future. Wind energy is harnessed by means of wind turbines which are fixed on high towers. The health of these towers is critical and has to be continuously monitored as they support and bear very expensive equipment.
Many wind energy farms are located offshore as they can harness un-obstructed wind flow. However strength and stability is then not only affected by structural dynamics but also wave hydro dynamics and a measurement of strain becomes a hassle due to the location.
The main objectives of this project are to put forward a convenient system capable of remotely obtaining strain data from the offshore towers, calibrating it with commonly used sensors and hence monitor the safety of the structure from the data so obtained.
