Wind Turbine Tower Monitoring Device
First Claim
1. A wind turbine installation monitoring device, for detecting relative movement between two adjacent components of a wind turbine installation, the device comprising:
- a deformable member;
securing means, configured to enable the device to be connectable to a wind turbine installation, in use, such that the deformable member is located across an interface between the adjacent components of the wind turbine installation; and
detection means configured to detect deformation of the deformable member and thereby to detect relative movement between the two components.

Abstract
A wind turbine installation monitoring device, for detecting relative movement between two adjacent components of a wind turbine installation is provided. The device comprises a deformable member together with a securing device. The securing device is configured to enable the device to be connectable to a wind turbine installation, in use. The deformable member is located across an interface between the adjacent components of a wind turbine installation. Further, a detection device is provided and configured to detect deflection of the deformable member and thereby to detect relative movement between the two components.

19. A method for determining the status of a bolt installed between two components of a wind turbine installation, the method comprising the steps of:
-
monitoring load experienced by the bolt over time; collating a time dependent loading characteristic for the bolt; assessing a status of the bolt; and raising an alarm if the assessing step indicates a failure of the bolt. - View Dependent Claims (20, 21, 22, 23)
