Spin fin piles are simple circular pile fitted with flat, steel plates ("fins") attached at a slight inclination over the lower
feet of the pile. A triangular spin fin pile is an alteration in ordinary pile where triangular shaped fins are welded to the
outskirts of the monopile. The spin fin piles are utilized as foundation for offshore structures. The behavior of spin fin piles is
hard to clarify utilizing simple pile–soil theories or two-dimensional mathematical investigations because of the complicated
geometry of the piles. At the point when the piles are driven, these piles rotate into the ground and achieve pile capacities far in
excess of conventional circular piles. In this paper the analytical investigation of the of triangular shaped spin fin pile
foundation resting in sandy soil with respect to its various parameters is carried out. For this purpose, analytical model of spin
fin pile is developed in MIDAS GTS NX software to simulate the pile foundation with different parameters proposed. A define
