Abstract: A mould aligner is used to align and lock a first mould and a second mould for moulding shell parts of a wind turbine blade. The mould aligner includes a first alignment segment configured to be attached to a first mould and a second alignment segment configured to be attached to a second mould. The second alignment segment includes a hydraulic cylinder having a barrel and a piston rod. The piston rod is axially displaceable and rotatable with respect to the barrel. The hydraulic cylinder includes a lock part having a first rod part and a locking element being provided on the first rod part. The first rod part is configured for being received in and engaged in the locking cavity of the first alignment segment. The hydraulic cylinder includes a cylinder part comprising the barrel and a second rod part having a piston.

Abstract: This invention relates to a detection system, a detection device thereof and a method, comprising a support structure having a contact surface for contacting a first surface of a moulding element having a composite structure, wherein a number of detectable element is arranged below the contact surface and configured to interact with the detection device via a magnetic field. The detection device is moved along a second surface of the moulding element and is configured to detect a position on the second surface of a reference line in relation to a detectable element, wherein the reference line is formed by the detectable elements.

Abstract: In a method for coastal protection, where the coastal area has an underlying freshwater basin and below this a salt water tongue which extends obliquely down into the coastal area, the pressure is equalized in the groundwater basin at least along an area at the shore line completely or partly to the atmosphere through pressure equalization modules, preferably in the form of pipes with a filter at the bottom, which extend down into the groundwater basin. This causes sedimentation of material and thereby an increase in the width of the shore. The resulting sand drift may be utilized for additional building-up of the coastal area by further establishing fascines.
