摘要	Somecorrosion defects will appear outside the aged submarine pipelines dueto the corrosive sea environment. These defects can depress thestrength and integration of the pipeline systems. This paper establishesa novel model using finite element method to describe thecorroded pipelines with randomly distributed corrosion defects according to theprobability function. Several free spanning pipelines models with random corrosionof different distributed parameters (averaged value and variance) are presented.Then the displacement and stress distribution of the pipelines arecalculated subject to external fluid forces. The wet modes arecalculated subsequently. At last the effects of the characteristic parametersof corrosion defects are discussed by analyzing the present results.Some conclusion may be useful for perceiving the randomly distributedcorrosion how to affect the pipelines operation status.
