摘要

As a first try in the offshore industry, this paper introduces a spectrum estimation method, called the Thomson spectrum estimation method, to effectively identify the structural system and the period of an offshore platform based on recorded topsides acceleration time histories. This method uses several leakage-resistant orthogonal windows, and the centered discrete-time Fourier transforms of these orthogonal windows appear in the solution of a particular form of a prolate spheroidal differential equation of the first order. Also investigated and presented is the performance of a deepwater platform in the Gulf of Mexico under major hurricane conditions (i.e., Hurricanes Ivan, Katrina, Rita and Ike) in terms of estimated displacement trajectories and recorded accelerations of the topsides.
