Structural Health Monitoring of Offshore Jacket Structure

The technology of condition monitoring for wind farm operation has been used for many years, such as Supervisory control and data acquisition (SCADA). However, structural health monitoring (SHM) of the support structure is still at the research stage. In this paper an offshore structure monitoring system for the offshore wind turbine jacket structure is proposed. The major monitoring items include vibration, strain and corrosion. In addition to those corresponding sensors, other instruments are also included in the proposed system to evaluate the structural integrity of the offshore wind turbine jacket structure. A detailed description of the monitoring methods and the framework of system are provided which is expected to be applied to the real support structure in the future.
