This paper introduces an efficient and automated computational framework integrating Python scripting with Abaqus finite element analysis (FEA) to investigate the structural behavior of long free-spanning submarine pipelines equipped buoyancy modules. A comprehensive parametric study was conducted, involving 1260 pipeline models, successfully performed a wide range parameters, including length (lp= 100, 200, 300 m), radius (rp= 0.3, 0.4, 0.5 thickness, type fluid, support, load ratio (LR= 0.2, 0.6, 0.8, 1), number modules (n= 0, 1, 2, 3, 5, 7, 9) its (lb=1/10·lp). The included verification process, providing presented framework. results demonstrate excellent agreement analytical numerical solutions, validating accuracy robustness proposed indicates that deformation natural frequency are highly sensitive variations in arrangements, geometry, conditions, whereas normalized mode shapes remain largely unaffected. Practical implications include ability rapidly optimize module placements, reducing resonance risks from vortex-induced vibrations (VIVs), thus enhancing preliminary design efficiency safety. developed approach advances existing methods by significantly complexity enabling extensive analyses, making it valuable tool for designing stable, cost-effective offshore systems.
