The requirements of the Rules of the Russian River Register on equipping cargo ships of all classes operating in the basins of Onega and Ladoga lakes with hatch covers for cargo holds are stated. The possibility of withdrawing the requirements on using hatch covers provided for by the Rules of the River Register is used by proving the equal operational safety of ships of the projects under consideration without hatch covers. The barges of projects 461G, R85, 81060, designed for loading bulk cargo by hydraulic filling and without hatch covers of cargo holds are considered. To prove the possibility of their operation in these basins without hatch covers, the results of model tests of ships in the experimental pool, as well as theoretical calculations of the total strength and emergency stability are used. The results obtained can be used by shipping companies that have vessels of these projects.
