Sensitivity Analysis of Marine Operations Subjected to Environmental Loads Using Co-simulation Approach

Abstract

In this paper, a sensitivity analysis evaluation strategy of marine operations subjected to environmental loads is present. The data generation is based on the co-simulation platform Vico where the virtual marine operation system is constructed. The dynamic time warping approach is used to process the rolling motion data in time-series sequences to measure the similarity. The sensitivity analysis is carried out based on the rolling motion data using the modified PAWN method, which can get the Kolmogorov- Smirnov statistic indicating the difference between unconditional and conditional CDFs. Simulations are designed and carried out to verify the feasibility. The results can provide a reference for allowable marine operation environment windows and also for further compensation research.
