The article presents a systematic approach to design of marine navigation channels parameters resulting from manoeuvring and operational safety. Relations between the parameters of waterway system elements and the conditions of safe ship operation have been determined and the objective function of waterway parameters' optimization problems has been minimized with respect to variables of construction and operation costs. These costs have been functionally associated to variables of channel width at the bottom and fairway depth. The method of fairway's width computation at specified safe depth at the preliminary and detailed stages of waterway design has been proposed. The results of this method application have been illustrated with two examples: 1. The modernization of Szczecin-Świnoujście fairway aimed at accepting vessels of 60,000 DWT capacity. 2. Construction of an approach channel leading to a newly built container terminal in Świnoujście harbour (Poland), handling ocean-going container ships of 20,000 TEU capacity.

本文提出了一种系统的方法来设计由操纵和操作安全引起的海上航行通道参数。确定了航道系统要素的参数与船舶安全运行的条件之间的关系，并就建造和运营成本变量将航道参数优化问题的目标函数最小化。这些成本在功能上与底部和球道深度处的通道宽度变量相关。提出了航道设计初步阶段和详细阶段在规定安全深度下航道宽度的计算方法。通过两个示例说明了该方法的应用结果：1.什切青-Świnoujście航道的现代化改造，旨在容纳60艘船只，000载重吨能力。2.建设引航通道，通往towinoujście港口（波兰）新建的集装箱码头，处理容量为20,000 TEU的远洋集装箱船。
