Response of Complaint Offshore Platforms to Waves

摘要

Probabilistic descriptors are developed for the response of structures of the Tension Leg Platform type to current and waves. These are obtained by Monte Carlo techniques by assuming the validity of the Morison equation. The results are compared to those obtained by using statistical linearization techniques. Also, for offshore platforms with higher natural periods of vibration, mean upcrossing rates for various levels of the structural response are estimated by simulation, by statistical linearization techniques, and by additional procedures developed in the report.
