APPLICATION OF RELIABILITY ENGINEERING TO SHIP STRENGTH DESIGN

The application to ship design of the Level II method in reliability engineering is described and two examples are given. In the case of upper deck plates undamaged by buckling, the safety index is greater than 4. In addition, that buckling strength reliability does not decrease even if ship design philosophy changes to favor the use of high-tensile-strength steel in lieu of mild steel. In the case of fatigue-damaged cruciform joints, on the other hand, the critical safety index is estimated to be in the approximate range of 3.1 to 3.6. The effect of load probability distribution on fatigue strength reliability is also made clear. Finally, partial-safety-factor formulas are derived for the buckling strength and fatigue strength of ship structures, taking the safety index into consideration.
