Abstract
A pad detail on the longitudinal coaming of a Panamax container vessel was selected as an example. This detail was chosen because of the well-defined loading due to hull girder bending. Large differences in predicted fatigue lives were found, ranging from 1.8 to 20.7 years.
The spreading of results is attributable to assumptions regarding loads, local stress determination and S–N curve. For comparison, a direct calculation of loads using the spectral method was performed.
Also this calculation showed a relatively short fatigue life of 5.3 years, although the structural detail is considered not to be prone to fatigue failures.

N2 - A comparative study on fatigue strength assessment procedures used by the classification societies has been performed by Committee III.2, ‘Fatigue and Fracture’, of the International Ship and Offshore Structures Congress (ISSC’2000). A pad detail on the longitudinal coaming of a Panamax container vessel was selected as an example. This detail was chosen because of the well-defined loading due to hull girder bending. Large differences in predicted fatigue lives were found, ranging from 1.8 to 20.7 years. The spreading of results is attributable to assumptions regarding loads, local stress determination and S–N curve. For comparison, a direct calculation of loads using the spectral method was performed. Also this calculation showed a relatively short fatigue life of 5.3 years, although the structural detail is considered not to be prone to fatigue failures.
