Influence of modernization of the ends of the ferry hull on seaworthiness

Abstract

   Due to the growing trend of aging of the ferry fleet, there is a great need to design new vessels of this type or modernize existing projects. Thus, according to an analysis of the Register Book of the Federal Autonomous Institution “Russian Classification Society”, over the past 10 years, only 3 ferries were launched for 115 ferry crossings on the Inland Waterways of the Russian Federation (here in after referred to as the IW of RF). In this connection, the article is devoted to the rationale for the modernization of a medium-haul car-passenger ferry for the Russian Federation, as well as
its impact on seaworthiness. The modernization under consideration is carried out on the basis of the newest medium-haul automobile-passenger ferry, which is being built on the territory of the Russian Federation, for the needs of the Baltiysk-Baltiyskaya Kosa ferry crossing. The selected prototype has contours characteristic of this type of vessel, sufficient cargo capacity and other features. At the same time, this project also has a number of negative factors affecting seaworthiness. Based on the described negative qualities of the prototype vessel, a theoretical drawing of the modernized vessel has
been designed. The effect of modernizing the theoretical drawing on seaworthiness was determined by testing physical models of the prototype vessel and the modernized vessel in the test pool of the Shipbuilding Research Center. The studies have been carried out in calm water, at speeds equivalent to the operational speeds of a full-scale vessel. At the same time, during the model tests, races have been carried out in regular oncoming waves, with wave characteristics determined by the Russian Classification Society. Based on the results of the described races, a number of advantages of the modernized vessel have been determined in comparison with its prototype.
