Abstract: The deepwater drilling riser is a critical part for the connection with the subsea wellhead and drilling platform, easily affected by the complicated marine environmental load and operation load, and is an important but weak link in the whole drilling equipment. The riser integrity management technology is an effective measure to guarantee the safe service performance of riser. This Paper expounds the riser integrity management scheme and summarizes the research progress of integrity management of deepwater drilling riser, including the damage identification and assessment of deepwater drilling riser, riser risk assessment, riser detection and maintenance, and riser integrity management specification and software primarily. It also recommends the development direction of future research.
