Research progress on protection and remediation measures for local scour of submarine pipelines
摘要
Abstract
In recent years,local scour of submarine pipelines has intensified,and there is an urgent need to ensure the safe and stable operation of pipelines.In this paper,recent achievements on the protection and remediation measures for local scour of submarine pipelines were reviewed and evaluated systematically.These measures could be categorized into three groups:active methods,passive methods,and self-burial promotion.Active methods are implemented by modifying the flow field and seepage field around pipelines,including floating flow-deflecting structures,rigid guide plates,bionic grass,permeable frame structures,and rigid protective plates.Active methods offer high flexibility and often combine sediment-promotion functions.However,as their sediment-promotion effect is constrained by upstream sediment supply,they are suitable for protecting newly laid pipelines and for remedying existing scour holes around in-service pipelines.Passive methods are implemented by enhancing the seabed soil's resistance to scouring and seepage-induced failure,including techniques such as riprap placement,sandbagging,flexible mattress installation,and soil improvement.Passive methods,while technically mature,involve high construction and maintenance costs and have significant environmental impacts.They are applicable for remedying pipeline spanning caused by geomorphic evolution and for emergency remediation of long-distance spanning.Promoting pipeline self-burial is achieved by accelerating the self-burial process,enabling the pipeline to be embedded in the seabed within a short period.This primarily includes methods such as spoilers.Once self-buried,the pipeline's risk of scour is significantly reduced.However,this approach imposes specific requirements on the local hydrodynamic conditions and seabed properties along pipeline route.It is suitable for protecting newly laid pipelines in areas where the flow is predominantly bidirectional,the pipeline axis is approximately perpendicular to the current direction,and the hydrodynamic conditions and seabed properties along the pipeline route are relatively uniform.关键词
