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.

US Classification:
702 38, 73623, 702 39
Abstract:
The invention relates to a method and inspection system for non-destructive inspection of a colony of stress corrosion cracks in a pipe or a vessel. The method comprises mapping the colony of stress corrosion cracks, identifying at least one individual crack to be sized within the colony, and sizing the at least one individual crack to be sized.

Abstract:
Method of determining an edge of a first anomaly in a wall of a pipeline from a first set of data elements representing measurements of the wall of the pipeline. An element of the first set comprises a first coordinate, a second coordinate, and a parameter being indicative for the presence and/or severity of the first anomaly a position along the wall indicated by the first and second coordinate. The method comprises determining a data element that is associated with a maximum in the severity of the first anomaly; evaluating a value of the parameter by comparing with a predetermined threshold; determining an initial edge data element for which the parameter has reached the threshold; determining a next edge data element; determining further edge data elements; and determining the edge of the first anomaly by combining the first and second coordinates of the determined edge data elements.
