The safety of ship operation is a priority for container shipping. Its provision is inseparably linked with proper container ship stowage planning. At the beginning of maritime container shipping evolution, container ship stowage planning was a fairly simple task, which could be solved without using complex computers and specialized software, in a relatively short time. With increasing ships container capacity, this task has become more complex and time-consuming. The complexity of container ship stowage planning is due to the fact that it is necessary to simultaneously take into account many factors that can have the opposite effect on the planning result. At the same time, normalization of one factor can lead to the fact that another factor will take an unacceptable value. The container capacity of the largest vessels today is 24,000 units in twenty-foot equivalent. Stowage planning of even an average feeder container ship with a capacity of 2000-3000 units in twenty-foot equivalent, in the modern conditions of container lines operation, requires the use of automated planning tools. Automation of this task solution has been attracting the researchers’ attention for nearly forty years. However, there were no outstanding successes. At the same time, the existing technical and software tools for container ship stowage planning, although allow you to solve this problem, but not to a sufficient level. It is important that the solution of the problem aims to achieve the greatest economic effect from stowage planning. It is noted that despite the fact that transportation safety is taken into account in the proposed models, these solutions are not enough. A mathematical model for solving the container ship stowage planning, based on setting the objective function and corresponding restrictions is offered in the paper. The maximum priority in the model is given to the safety of transportation. The importance of the economic effect from the stowage planning is recognized, but is not considered in this paper.
