Abstract

This paper discusses Arctic shipping risk analysis. A program of research was started in 1982 to develop a risk analysis model. A computer program, ASPEN (Arctic Shipping Probability Evaluation Network) has been the focal point of the research. The elements of the program mirror the elements of the problem. These include: environmental definition, the navigation and ice avoidance process (including human behaviour), ship/ice collision mechanics and structural limit states (failure mechanics). All aspects of the problem are variable and must be treated statistically. Related studies to obtain the statistical parameters are discussed. The numerical methods employed by the program are described. Many fundamental issues remain unsolved, particularly those related to correlated variables. The paper concludes with a discussion of required developments.
