Optimization of Piling locations for Pumping Structure using Finite Element Method

Abstract
Long stroke pumping system for sucker rod reduces energy costs and improves performance over time. Long stroke Pumping units, by their nature, transmit very large forces to the mounted piling locations, wherein the installation of the units is not on plain barren land, but in the seashore, part land part water, elevated base. Piling provide a means of distributing these forces over a broad area allowing the soil and subgrade to generate enough strength and stiffness to withstand them while yielding only very small deflections. Piles quantity, positions among themselves become challenging due to various loads exerted due to operational loads and unit overhaul scenarios where unit must be moved horizontally or vertically. In this work, the entire 3D model of pumping tower assembly is numerically simulated using commercially available Finite Elements Analysis (FEA) software. Non-linear structural FEA analysis is conducted with combination of the pile locations for operational loads. Piling locations are optimized with the combination of cross beam, till the deformation and stresses are within limit for all the connecting parts. These components are designed, analyzed and redesigned till the product is safe for operational loads, The FEA results are then validated with the field data and found to be close enough.
