A method is provided in which an ultrasonic signal is generated as an electromagnetic ultrasonic signal by the at least one transmitting transducer, which is in the form of an EMUS transducer, by means of a conductive layer arranged on the surface of the object or in said object. An evaluation apparatus is used to utilize the ultrasonic signal detected by the at least one receiving transducer, which is in the form of an EMUS transducer, in order to determine a flaw in the form of a delamination, a porefield or other such two-dimensional inhomogeneities.

Method for non-destructively testing objects, in particular planar objects, made of a fibre-reinforced composite material

Seal arrangement for a joint of two joint elements, in particular realized as a monopile and a transition piece, of an offshore structure, preferably an offshore wind energy installation, in particular a substructure thereof, in which, for the purpose of producing a stable joint, an upper joint element and a lower joint element are inserted into each other in a clamping manner by means of at least one seal unit, comprising one of the joint elements and the at least one seal unit fixed to the joint element, in such a manner that the seal unit, in a joining position, is arranged between an inner joint surface of one joint element and an outer joint surface of the other joint element, at least one seal unit having at least one elastic sealing element, which extends in the circumferential direction around the entire circumference and the thickness (D) of which is greater than the thickness (D') of an adjoining seal unit region and method for producing a seal arrangement.
