For River-Sea ship, structural of hatch coaming are expanded to improve transportation,

so it affect the longitudinal ultimate strength of the ship hull. In this paper, application ofnonline

finite element method for ultimate strength of the River-Sea ship hull structure under bending moment

The calculation results of the ultimate strength of ship hull to build nexus between Bending

moment- Rotation cuver in the sagging moment and hogging moment cases as a basis to calculate

longitudinal ultimate strength and calculate, design of ship hull structures.

Keywords: Tfever-Sea iAp, nonlinefinite element method, ultimate strength, bending moment.
