Abstract:

Method for non-destructive inspection of defects in a surface of a pipeline or storage tank. The method includes carrying out a first way of non-destructive inspection for determining a first defect pattern and carrying out a second way of non-destructive inspection for determining a second defect pattern. The method includes identifying at least one defect of the first defect pattern and at least one defect of the second defect pattern which represent one and the same defect, and comparing the dimensions and optionally also the positions of the identified defects so as to obtain a difference in dimensions and optionally also in the positions. The method also includes obtaining a plurality of such differences and obtaining at least one parameter representing said differences, and correcting the dimensions and optionally also the positions of defects of the first defect pattern by using the at least one parameter.
