Design Load Calculations for Iceberg Impacts

摘要

A probabilistic framework is presented for determining design global iceberg impact loads for offshore structures, with example calculations provided for a cylindrical GBS (gravity based structure) and an FPSO (floating production, storage, and offloading system). Emphasis is given to the development of efficient simulation techniques, the effect of iceberg rotation on loads, modelling local shape of the iceberg at contact point, and sensitivity analysis to evaluate areas of uncertainty which cannot be treated probabilistically.
