Modular design of the barge platform

Abstract

The paper presents the solution of the problem of creating the design of the barge-platform of the "M-SP 3.5" class of the Russian Classification Society (RCS), intended for manufacturing outside the shipbuilding and ship-repair enterprise on the prepared site near the water body. Hull assembly should be made of separate parts (modules), which are manufactured in the conditions of shipbuilding production and delivered to the place of assembly by automobile or railway transport. Welding should not be used in the assembly process. It is suggested to assemble the barge hull from flat sections of 12,00×2,40 m and fractional sizes; bolted joints should be used during assembly. An example of barge construction of op-determined dimensions is considered. Calculation of the overall strength of the hull assembled from individual sections by means of bolted joints is performed using the ANSYS program complex. It is shown that the strength of the hull and bolts is ensured for the load regulated by the Rules of RCO. The use of bolted joints in forming the hull makes it difficult to ensure its impermeability, in this connection the buoyancy and non-floodability of the barge is proposed to be ensured by means of flexible tanks filled with air. Design and production of such tanks is currently carried out by a number of companies in the Russian Federation.
