Abstract:For all-steel tubular frame mooring structure of large offshore oil wharf,the calculated fatigue life using calculated mooring load will be short and be deviated from the actual situation.Currently there are fewer researches on the analysis of the measured mooring load,and they are disorder.This paper analyzes actual measuring mooring load of 300 000 DWT crude oil wharf expansion project in Ri-zhao port Lan-shan harbor,and finds out the probability law of distribution for mooring load and analyzes the fatigue damage of the tubular nodes.The analysis results show that the worst fatigue damage nodes are middle tube nodes,and mooring load has little influence on fatigue damage to all-steel tubular mooring pier,only 10-4 orders of magnitude.

Abstract:Large-scale oil wharves usually adopt the layout of butterfly.Generally,the critical loading relating to the overall structure stability is the wave loading.Typically,the maximum wave height and its corresponding wave period or the maximum wave period and its corresponding wave height are chosen are the design wave parameters.However,it is indicated by calculations that those are not necessarily the critical condition regarding the wave parameters.By reference to the numerical analysis result of the factor of pile group,this paper studies the change of wave loading on small-scale pier column structure with different wave heights and wave periods,and also studies the general pattern of the overall stability of separate caisson dolphin structures.
