Sažetak
The article describes the remedy for a misalignment of Y-joint in hemispherical and torispherical heads of the bilobe cargo tank on a Liquefi ed Petroleum Gas Carrier. The misalignment is the result of connecting relatively thin shells and production diffi culties. The measured rather large shell eccentricity in the Y-joint causes bending moment, which cannot be withstood by shells designed as membrane, and therefore it has to be controlled. The remedy of misalignment is
achieved by reinforcement of the Y-joint with inside and outside bars and knees. In this way stress concentration determined by the FEM analysis is reduced within the allowable stress given for secondary stress level.
