The article presents a systematic approach to studying sea waterways. Relations between the parameters of sea waterway system elements and the conditions of safe ship operation are determined. Principles of formulation of the simulation experiment research process in the sea waterway system design process at the preliminary and detailed design stages are defined
A seaport is presented in this article as a system composed of various types of waterways. The author has defined relationships between port waterway system elements and conditions of safe operation of ships in port. Relationships were determined between the conditions of safe operation of ships and the parameters of the following port waterways: anchorage, fairways (approach and inner channels, port entrances), turning area and port basin. The identified relationships between port waterway system and conditions of safe ship operation provided a basis for formulating the objective function of waterway parameter optimization during port design. In practice, these relations were used to determine the parameters of the Outer Container Terminal being built in Świnoujście, where two optimization problems were to be solved:1. The optimization of approach channel parameters,2. The optimization of parameters of the port entrance, turning area and port basin.The Outer Container Terminal in Świnoujście is expected to handle ocean-going ships with a length overall Lo = 400 m, and its projected capacity is estimated at 1.5 million TEU per year, a figure that can be doubled in the future
This paper presents developed optimization methods for sea waterway systems. Objective function of optimization of sea waterway systems have been formulated and its detail form for fairways has been determined. Three probabilistic methods for determining safe bed-breadth of fairway are described. Limitations of the presented methods are also discussed. The developed optimization methods for sea waterway systems have been applied to determine parameters of a modernized fairway between Świnoujście and Szczecin as well as its navigation systems
