Ultrasonic testing / material thickness measurement
These methods are used for steel hulls in sailing and motor yachts and are an important
parameter in determining the value of a boat and also a decisive factor for safety on board.
Corrosion affects the thickness of the material and associated components can lose their
E/M/S experts carry out non-destructive material testing of the hull of steel hulls by
ultrasonic measurement. Prior to this, the E/M/S expert carries out a visual inspection of the
Using a special ultrasonic testing device, it is possible to examine homogeneous materials
(steel without protective coating) with a material thickness of 1 to 250 mm. For steel hulls
with protective coating from 2.5 to 20 mm. In most cases it is not necessary to remove the
protective coating for the material thickness measurement.
The test is carried out on land. The results of the test are documented in the E/M/S test
