Analysis and reinforcement of a tanker barge for NAABSA1 class conditions

Abstract

The paper considers the issues of general longitudinal, transverse and local strength of the non-self-propelled tanker barge hull of 500 tons deadweight from the standpoint of interaction with the ground during drainage. The work was done to substantiate the conditions for compliance with the Register class symbol NAABSA1. The need to strengthen the keel in the forepeak area is shown. A simple scheme for strengthening the keel is proposed. The implementation of the proposed scheme ensures the safe operation of the vessel under NAABSA1 conditions with landings on the ground and drainage.
