3049 Review of repairs to offshore structures and pipelines

Overview:

This review is a comprehensive study, with 172 repairs recorded and it builds on an earlier 1982 review. It covers repairs on fixed steel platforms, concrete gravity platforms, articulated or compliant structures, floating production facilities, sub-sea structures, pipelines and flowlines.

The data is analysed in various ways including cumulative total of platforms by construction material per installation year, cumulative repairs per national sector population, frequency of repairs per structure year versus water depth, causes of damage, repair types, number of repairs versus structure age and reported costs. The report also contains conclusions and makes recommendations based on the findings.
