Non-Parametric Method for Estimating Extreme N-Year Profiles for Loop Current and Eddies

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...
