Netherlands: When conducting a life cycle assessment of a wind turbine, or any
other product, researchers begin by diagramming each stage of its existence,
from manufacturing through end-of-life disposal.
This wind turbine didn't do so well, it didn't freeze up or catch on fire, it
blew over... from the wind.

Abstract
The dynamic forces subjected on a wind turbine combined with high fatigue
loading may result in a foundation failure and potentially reduce the expected
service life of the tower. Foundation failures may include excessive tower
movements, tilt of a tower, or even loss of contact with the ground. The state-
of-the-art practice for foundation monitoring involves use of sensors such as
tiltmeters, inclinometers or strain gauges at wind farms to measure
displacements or tilts, which can be expensive, complex, and time consuming.
The research presented in this paper, explores the feasibility of a novel, low-
cost mechanical displacement indicator to continuously monitor tower movement
relative to the foundation base. In addition, finite element models were
developed to investigate the long-term performance, and potential degradation
of the wind-turbine foundation system. Modeling results when combined with
field monitoring work would aid in improving the design practices or available
standards to predict the service life of a wind-turbine foundation system.
