WEST SOLE WE PLATFORM: DETECTION OF DAMAGE BY STRUCTURAL RESPONSE MEASUREMENTS

The removal of a platform (WE) from the West Sole Field in 1978 provided an unusual opportunity to practically test the effectiveness of structural response measurements to detect damage. The platform was deliberately and progressively damaged prior to removal by cutting members. Measurements of the dynamic response of the structure to ambient excitation were made before damage and after each cut using accelerometers placed above water and below water. The work helped define the capabilities of structural monitoring techniques and thus their potential as an aid to inspection. It was shown that complete severance of a member can be detected by overall measurements above water and that flooding and part severance can be detected by local measurements underwater. The application of the methods to other structures is discussed.
