In the shipbuilding industry, the concern of the fatigue problem has been a very important item for the ship owner, shipbuilder, classification society, etc. The evaluation method for fatigue strength is very complex and a time consuming job, but for maintenance purposes it is a very critical item. However, for the opening and hull outfitting, pipes and control units installed on the main deck, the fatigue problems are not considered/evaluated like the other hull structure members. Those are installed and constructed according to Yard's experience and practice without appropriate direct verification procedure for fatigue strength, and hence the occasional occurrence of cracks on the outfitting and around holes on the main deck. For these reasons, the fatigue strength in way of outfitting and openings installed on the main deck are evaluated and verified with the simplified method developed through a Joint Development Project (JDP) between Daewoo Shipbuilding Marine and Engineering (DSME) and Det Norske Veritas (DnV). In addition, the effectiveness of the doubler plate underneath the various supports on the upper deck has been evaluated using the method to be introduced in this paper.
