Ultimate Strength Performance of Tankers associated with Industry Corrosion Addition Practices

Author(s):
Do Kyun Kim, senior lecturer at Universiti Teknologi PETRONAS (UTP)and Jeom Kee Paik, president at The Korean Ship and Offshore Research Institute (KOSORI) investigate the effect of corrosion additions on the ultimate strength performance of tankers

 

Abstract :
In ship and offshore structural design, age-related problems are important factors to be considered in building a robust structure as they have a significant influence on the residual structural capacity. In shipping, corrosion addition methods are widely adopted in structural design to prevent structural capacity degradation.
The historical trend of corrosion addition rules for ship structural design and their effects on ultimate strength performance is considered in this report Three types of standards or rules based on corrosion addition models, including historic corrosion rules (pre-CSR), common structural rules (CSR), and harmonised common structural rules CSR-H) are compared with two other corrosion models - one suggested by the Union of Greek Shipowners (UGS) and the Paik’s corrosion models.
To identify the general trend in the effects of corrosion damage on the ultimate strength performance, four representative sizes of double hull oil tankers, e.g., Panamax, Aframax, Suezmax, and VLCC, were applied and ALPS/HULL and the ALPS/ULSAP computer simulation code were adopted for evaluation of ultimate strength performance.
