DESIGN CRITERIA OF THE LONGITUDINAL HULL GIRDER STRENGTH BASED ON THE RELIABILITY ANALYSIS

The application of reliability analysis if investigated as a probabilistic approach to the assessment of ship's structural strength and to the establishment of design format for longitudinal strength. Reliability analysis is carried out for 34 tankers and bulk carriers for some failure modes such as tensile yielding, compressive buckling, ultimate strength of hull girder and fatigue failure. Reliability indices with respect to ship type and ship size are discussed and a target reliability index is suggested. System reliability is calculated for stiffened plate. The partial safety factors corresponding to the specified target reliability levels for the design format are obtained. Finally, a design format using partial safety factors is proposed to provide more uniform levels of safety.
