Section 9 Fatigue Analysis

901. General

1. The possibility of fatigue damage due to cyclic loading should be considered in the design of self-elevating and column-stabilized units.

2. The area anticipated stress concentration is to be considered to fatigue strength, the fatigue analysis is to be based on the intended mode and area of operations to be considered in the unit's design.

3. The fatigue analysis should take into account the intended design life of the unit and the accessi-

bility of load-carrying members for inspection. The fatigue life is normally not to be taken as less than 20 years.
