Hull reinforcements of ships moored at sea

Abstract

One of the most dangerous cases in the operation of a vessel, along with working in ice, is mooring operations at sea. Unlike mooring operations in ports to berths, mooring on the waves in the open sea is complicated by the movement of ships relative to each other. As a result, the load on the ship's side structures increases significantly. The rules of the Russian Maritime Register of Shipping require the installation of additional reinforcements of the sides and superstructures on ships moored in waves from 4 to 6 points. These requirements appeared in the Rules quite a long time ago and have undergone significant changes over the years. The currently existing requirements have a number of disadvantages due to the method of calculating the pressure intensity of moored vessels. The paper shows the existing shortcomings of the Rules and suggests methods for solving these problems.
