Wave Current Coupling Analysis And Software Development Of Submarine Pipeline

PIPEline,as one of the five transportation modes,has many advantages,such as high safety,good continuity and large transport capacity.It has been widely used in the transportation of marine oil and gas,and the PIPEline transportation volume in developed countries is close to 80%.However,the PIPEline is difficult to be inspected and maintained because of underwater.Especially the sea PIPE of offshore section,which is located in the offshore area,is affected by the effect from near bed.The coupling effect of wave and current is significant,which has a great impact on the submarine PIPEline.Therefore,the simulation,calculation,analysis and optimization of the wave coupling field can provide strong theoretical support for the design,construction and construction of the submarine PIPEline in the nearshore section.This paper focused on solving the problem of wave flow field coupling analysis algorithm and the software development.And then it can make the purposes achieved,which reduce submarine PIPEline operation risk and improve operation management and accident emergency response ability.It also has very important significance about follow-up study for submarine PIPEline projects related underwater engineering.Based on ANSYS,which called the large scale finite element software,this paper calculates and analyzes the coupling field of wave and current in the offshore PIPEline by modeling parameterization,parameterization calculation,and parametric processing.The research explores the wave flow coupling phase angle,and then using the finite element and command flow algorithm will be PIPElined,form different subroutines,such as modeling procedure,wave search subroutine,post processing subroutine etc..Developing the software by The Microsoft Corp of the C# language,can get the formation of human-computer interaction model of window type.It can change the miscellaneous code into interactive window service in order to convenient for the operators to call.This paper optimizes the algorithm on the basis of software development.It reduces the time costed by computer coupling analysis,improving the computer efficiency,developing the DBS and provides the efficiency guarantee for the similar engineering analysis.The idea of the optimization algorithm can also provide some reference for other engineering related calculation.
