Análisis experimental de la resistividad del acero corroído del doble fondo del buque Paola

Abstract

This experimental study analyzes the impact of corrosion on the double bottom of the cargo ship Paola, currently operated by GalapagueñaCorp. S.A. The main objective of this project is to evaluate the resistivity of a corroded double bottom tank through compression tests in the material's elastic zone. To this end, specimens with corrosion levels of 0%, 5%, 10%, 20%, and 25% were used in the vertical structures, to quantify the effect of corrosion on structural integrity using dimensionless failure parameters.The results obtained indicate that a 25% corrosion level in the ship's structures severely compromises the feasibility of operations in coastal areas, as the structure fails easily under the applied load due to the low rigidity of the material. Based on these findings, it is concluded that the maximum acceptable corrosion percentage in structures affected by this phenomenon is 20%. In contrast, at 25% corrosion, the damage is significant, although the classification society ABS establishes that the allowable corrosion limit is 30%, with a high-risk level.
