tanker structural analysis for minor collisions In a study of the behavior of a longitudinally framed oil tanker structure during a minor collision in which the cargo tank remains intact, a plastic analysis procedure, based partly on model tests and inspections of collision damage, was developed and applied to a limited number of idealized ship collisions.Structural Analysis of a Barge Midship Section Considering hull cargo tanks structural analysesStructural failures in the barge midship sections can cause operational delay, sinking, cargo loss and environmental damage. These failures can be generated by the barge and cargo weights, and wave load effects on the midships sections. These load types must be considered in the design of the barge midship sections.

The centre line ballast tank arrangement enables a significant proportion of the topsides module weight to be directly opposed by buoyancy forces.
Jan 01, 2009 · As illustrated in Figure 2, there are totally seven pairs of cargo oil tanks in the ship. The odd numbered cargo oil tanks were pre-loaded with product oil. Density of the product oil was 0.73 t/m3.
