This project investigated the accuracy of non-invasive deepwater subsea inspections performed by common ROV-supported inspection tools and provided a comprehensive assessment of the knowledge gained from recent work on subrope behavior.
The objectives were:
Evaluate accuracy of polyester subrope damage detection performed by ROVs following hurricanes and other events (i.e., loop current) that exceed the 100 year design criteria.
Perform a quantitative evaluation to determine if ROV survey results and resulting life damage estimates are acceptable.
Explore the viability of a newly conceived method for predicting remaining life based on adapting traditional methods for application for synthetic ropes, like polyester.
Identify non-invasive inspection methods other than ROV surveys and compare ROV inspection to physical insert testing to determine the level of accuracy that can be expected.
Identify the most reliable methods, including but not limited to insert tests, to verify that the mooring system is fit for purpose.
