Annotation

The subject of the article is the architectural and structural peculiarities of roll-on/roll-off vessels (Ro-Ro). It is necessary to have a substantial information base to design such type of vessel, including existing prototype vessels characteristics and its development experience. There is a lack of this data base in domestic shipbuilding, since Russia haven’t specialization in the creation of the Ro-Ro ship. At the same time, there is also a growing interest in this topic, because of Ro-Ro vessels operation allows to service ports with little developed infrastructure or without specialized terminals, while ensuring high cargo handling speeds (200-400 tons/hour). Thus, the purpose of the study is to make some generalization in the field of architectural and structural peculiarities of roll-on/roll-off ships designed for the transportation of wheeled vehicles and unified packaged cargo in containers and roll trailers. Vessels with a deadweight DW from 4’500 tons to 55’700 tons were accepted for consideration, for them the features of the layout of cargo spaces, the relationship of their parameters with the transported type of cargo, the presence and location of special equipment were highlighted. Statistical dependencies reflecting the relationship between deadweight, the total length of cargo lines, the number of transported TEU and the main dimensions of existing Ro-Ro vessels are found. The difficulties encountered in determining the calculation model and the values of local loads from wheeled vehicles, forklift truck are indicated. The problems arising in the process of hull structure design for the elements of the Ro-Ro decks and sides while meeting the requirements for local strength, as well as the specifics of ensuring the longitudinal strength, are noted. Keywords: architectural and structural characteristics, roll-on/roll-off vessel, Ro-Ro, vehicle cargo ship, hull ship structure, statistical data, Ro-Ro decks
