Effective inspection solutions for coated and non-coated subsea pipelines

摘要

WHILE CORROSION POSES a substantial threat to the integrity of ageing subsea assets, the inspection and integrity assessment of the subsea assets is often challenging and costly due to accessibility issues and difficult inspection conditions such as water depth, visibility and temperature. Despite that, there is an increasing requirement for splash zone and subsea inspection in order to determine the fitness-for-service for lifetime extension and condition monitoring of the assets such as risers, caissons, conductors, flexible risers, subsea pipelines and structures, etc.
