Abstract
In offshore wind turbines the transition between the ground pile and the supporting structure is often realized as a grouted joint. This is a pipe-in-pipe connection in which the gap between the two pipes is filled with grout (fine-grained, high-strength concrete). A typical failure is the slipping through of grout connections. This results in the gradual occurrence of larger deformations until the failure. Therefore, the measurement of the relative displacements between pile and sleeve of a grouted joint of an offshore wind turbine is a decisive factor for the evaluation of the load-bearing behavior. This can be performed with manageable effort for foundation structures with grouted joints located above water. A major challenge, however, is the measurement of displacements under water. The Institute of Building Materials Science has developed a mobile measuring unit in order to be able to carry out this measuring task.
