Analysis and selection of reinforcements of the outer plating of the vessel for safe operation in ice conditions

Abstract

In this article the results of substantiating the optimal choice of geometric characteristics of the hull strengthening tanker "Ostrov Russkiy" for ice class Ice1 according to the requirements of the Rules Russian Maritime Register of Shipping in order to ensure local strength when operating ship in ice are presented.

To check the local strength of the side construction, calculations of the stress-strain state of structures using the finite element method were performed. Various methods of partitioning finite elements in the CAD software Solidworks Simulation are considered and the optimal size of the computational mesh is selected. The reliability of the calculation results obtained was verified by the criterion of the influence of the installed structural elements on the strength of the side construction. As a result of comparing three options for ice reinforcements, from the point of view of ensuring the strength and cost-effectiveness of the structure, the optimal scheme for strengthening the sides of the vessel was selected. Based on the results of the calculations, a design for reinforcement of the hull of the tanker "Ostrov Russkiy" for ice class Ice1 was developed and approved by the Russian Maritime Register of Shipping.
