Design Lifetime
Design lifetime = 2 × 10 6 cycles over 25 years = 220 cycles / day = 110 lifts / day Expired lifetime = (19 × 30) = 570 days × 220 = 125400 cycles Estimated life expiry = 125400 2 × 10 6 = 6.3 % From this approximate calculation it seems unlikely that the crane component failed directly as a result of the type of fatigue loading for which it was designed.

Re-evaluating the design life of buildings
Bridge bearings may have a life span of 20-45 years. If the whole structure is designed to last for 120 years, the design may be required to eliminate the use of these or have a service plan to inspect and replace them. If the structure is designed for one year''s use only, you may choose cheaper alternatives or simply ignore them if you can.
Extending design life, improving integrity of flexible pipe
Given that most flexible pipe systems are designed with a 20-25 year service life, only a small percentage in operation are close to this service life. Should flexible pipe failure rates follow the typical "bath-tub" analysis curve, it is possible that the type and quantity of flexible pipe damage/failure mechanisms will increase in the future.
