Offshore Oil Platform Underwater Inspection: A Study and Evaluation of a Scanning Beam Sonar.

reportActive / Technical Report | Accession Number: ADA147780 | Open PDF

Abstract:

This report examines a method to perform unannounced inspections of producing offshore oil platforms for possible structural deficiencies. An off-the-shelf scanning beam sonar imaging system was selected and evaluated at a candidate platform. The test results indicated that the scanning beam equipment must be located close to the structure for usable images. This requirement would necessitate permission from the operator. Possible modifications to the equipment tested are recommended. Author
