The present paper discusses results from a numerical investigation on the axial–lateral interaction of pipes with cemented sand. Soil friction between seabed and pipeline plays an important role. The interaction between pipe and soil is often referred to as Pipe Soil Interaction (PSI) which represents the evaluation of seabed stiffness and equivalent friction that represents the soil resistance to the movement of pipe. The evaluation of friction factors is important for the Pipeline–Seabed Interaction (PSI) and Cable–Seabed Interaction (CSI) within upper 1 m of natural seabed, where these factors are crucial for long-term stability of subsea pipelines but it’s stability depends on the soil properties and seabed zonation. The seabed zonation will be done by the detailed analysis of geological, geophysical, and geotechnical studies. The PCPT results give the resistance offered by seabed which can determine the shear strength of existing seabed stratum. The coefficient of friction from the test can judge the serviceability of the pipeline, which can also reduce the effect of buckling in subsea pipelines. The geotechnical & and geophysical investigations evaluate the appropriate path for installation of subsea pipelines. The bathymetry survey helps in seismic profiling & and geological study of the existing stratum. The calculations of equivalent friction factors from the extracted soil samples are based on analytical/theoretical formula proposed by Hanners. The same things have been verified in this study using Coupled Eulerian–Lagrangian (CEL) analysis using ABAQUS/Standard software. The failure mechanism has been observed for axial and lateral soil interactions. In present study, emphasis has been given on cemented rocky seabed behavior. Overall accurate evaluation of soil frictional resistance is very significant for cost optimization of subsea projects.
