Underwater Inspection/Testing/Monitoring of Offshore Structures.

摘要

Requirements for underwater inspection of offshore structures and the techniques and tools to conduct such inspection vary widely from country-to country. The purpose of this six month study was: (1) to identify and describe all actual or potential underwater inspection requirements (national and international) for fixed concrete and steel structures promulgated by the governments of offshore oil and gas producing countries and by the offshore operators themselves; (2) to identify and assess the state-of-the-art in underwater non-destructive testing/monitoring/inspection of offshore structures; (3) to evaluate the capability of servicing and hardware producers to meet the inspection requirements;and (4) to describe and establish priorities for specific tasks for technology development that should be undertaken to satisfy current and future requirements. While this study concentrates on fixed offshore oil and gas structures,the results also reflect the state-of-the-art in underwater inspection/testing for other offshore structures as well, e.g.,floating power platforms,offshore terminals and deepwater ports.
