Comparing records can reveal aging subsea equipment condition

摘要

Advances in technology, data science and operating experience have made inspecting the 'uninspectable' possible. Operators of aging subsea assets have a unique opportunity during the next decade to extend the operating lives of what will prove to be some of the most robust equipment ever built to extract off-shore hydrocarbons. In the late 1990s, when this generation of equipment was installed, uncertainty about its performance in a deepsea environment produced 20-year designs that were based on conservative assumptions about how conditions would affect corrosion, motion and fatigue. Generally, this is good news for life extension.
