The objective of this study is to perform a round robin study on spectral fatigue damage assessment of butt-welded joints and to identify the existing uncertainties and challenges in the commonly used approaches. Various methods are employed to estimate the fatigue damage of butt-welded joints located in the deck and shell structure of a bulk carrier. Hydrodynamic loads are calculated based on strip and panel theory and closed form hydrodynamic loads. The finite element method and beam theory are both feasible to calculate the stress responses and the analysis procedures for each method are introduced and the corresponding results are compared and conclusion are derived.
