摘要

Offshore structures in the Bohai Gulf are often under the threat of sea ice. Due to the fact that the ice environments, such as the ice thickness and tensile strength, often change over the years and in the sea areas, it is better to determine a series of ice cases with the occurrence probability to predict the ice force on the structure in the Bohai Gulf. To calculate the ice force on the structure accounting for the uncertainty of the ice environments, such as the ice thickness and tensile strength, a method for determining the ice case in the Bohai Gulf was proposed, and an element was developed to simulate the sea ice as a user modification of the Finite Element Analysis (FEA) commercial software ABAQUS. At the same time, the Winkler foundation and the failure criterion introduced by Reinicke and Remer were implemented in the element to take into account the bending failure of the sea ice and the influence of the buoyancy force. An open and universal framework for determining the ice cases in the Bohai Gulf has been proposed.
