Trial Calculation of Design Ice Loads on an Arctic Structure for Offshore Sakhalin

摘要

In this study, a trial calculation of design ice loads on a candidate arctic structure for offshore Sakhalin is conducted. Estimation of the design ice loads is performed using a probability based method proposed by the author. This method calculates a probability density of ice loads by the Monte Carlo simulation and produces a return period -ice loads relation from the simulated probability density. The method proposed is briefly explained. Two important elements of the method, the ice load models for possible ice - structure interactions which are specified in interaction scenarios associated with offshore Sakhalin are determined and probability density functions for variables associated with ice and sea condition at offshore Sakhalin are also determined. Some trial calculations are done. And some necessities to apply the method are discussed.
