Method of testing an offshore structure for mechanical faults

摘要

A method of testing offshore structures for mechanical faults includes the application of a tensile force to the structure from an outside point such as a tug boat the abrupt uncoupling of the tensile force from the structure and the detecting and indicating of the local vibration behaviour of parts of the structure by acceleration detectors mounted on said parts. The information thus obtained is analysed and may be compared with information about this local vibration behaviour obtained from calculations, simulations and/or earlier tests.
