ASSESSMENT OF ULTIMATE LONGITUDINAL STRENGTH OF AGED TANKERS

This paper investigates the influence of thickness diminution because of the ultimate longitudinal strength. At the beginning, the characteristic of corrosion damage in existing single hull tankers are investigated. It was found that the diminution ratio of the thickness at the deck/bottom part is almost the same as that of the section modulus of the hull girder cross-section. Then, two series of progressive collapse analyses are performed on hull girders of eleven single hull tankers that were subjected to longitudinal bending, and the ultimate longitudinal strength was evaluated. Both the FEM and Smith's method are applied for analyses. Almost linear relationships were found between the reduced section modulus and the ultimate longitudinal strength of aged single hull tankers with corrosion damage. The paper concludes that the reduction of the section modulus should be with 15% of its original value to prevent break-up of the hull girder in the case of single hull tankers.
