... Abstract Extreme N-year current profiles for Loop Current and Eddies (LCE) are required for the strength and fatigue assessment of the risers and wellhead/casing systems. The profiles for different return periods (i.e., N = 1, 10, 100, etc.) are derived from an extreme value analysis (EVA...

Abstract This paper outlines a methodology for developing consistent robustness criteria; accounting for multiple hazards that may occur during long Return Period (RP) events, and accounting for other degradation mechanisms unrelated to long RP events but, based on experience, were root causes...

... through two sides, i.e. better design standards and more rigorous operation practices. On the design side, there appears to be a lack of clear guidance on designing a mobile mooring system to a proper return period. The gap is prominent especially for moorings in tropical cyclone (aka hurricane or typhoon...

In order to correctly evaluate the required return period (up to 1 on 10,000 years) extrapolating the tail of the distribution from historical database provides...

...-2 and the more recent API adoption, RP2EQ, provide performance-based recommendations for selection of a two-level seismic design. At the first level the structure is designed to retain its full capacity (and likely its operability) at ground motions with a return period typically under 200 years...

By estimating the response of the mooring system based on limited dynamic analysis for various return periods and loading directions, a regression model is used to develop the probability distribution of the conditional probabilities of failure under each return...

Using these models, the probability of a mass gravity flow impacting the seafloor installation(s) should then be computed for all relevant scenarios and return periods in order to derive the annual or lifetime probability.
