Structural Health Monitoring software (CMSSHM) is a Plug-In to our standard Condition Monitoring Software, which enables the continuous measurement and recording of raw data. It also post-processes the data to give a continuous on-line record of the condition of towers and sub-structures.

The system comprises measurement hardware as well as the CMSSHM software. At the simplest level, the system can operate from a single 2D MEMS accelerometer, however a much more detailed assessment can be built by incorporating a range of different sensor types measuring at various levels and locations within the support structure (tower, transition piece and foundation).

A Finite Element Model converts data from a small number of measurement positions into an overarching model of the whole structure, providing a Digital Twin which calculates motion, loading and eigenfrequencies of the structure from a continuous stream of live data.

Rainflow counting and damage equivalent loads are used to assess ongoing fatigue damage, to the structure, and can be associated with particular damaging events (eg storms) and operating conditions to help optimise operations in the future.

Knowledge of how the structure is aging also leads to a focused inspection regime, allowing longer periods between routine inspections on structures which have not experienced significant events.

This gives a mechanism for plant protection and life extension, which can be applied with minimum effort and integrated with other condition monitoring functions.
