ANALISA KEKUATAN SPUD SEBAGAI SISTEM MOORING BARGE MOUNTED POWER PLANT 60 MW DENGAN METODE ELEMEN HINGGA

Abstract

Spud is one of many mooring system that only often used for barge ships, such as a barge mounted power plant (BMPP). PT PAL Indonesia (Persero) has the primary design and size guidelines of the spud, but there has not been any strength analysis for it. Thus, this analysis will be done through AutoCAD 3D and the analysis using the ANSYS program. The results obtained are the loading that occurs on the spud itself and the strength value of spud bracket, so that the feasibility and safety of using spud as a mooring system for BMPP can be determined. This analysis uses the finite element method which has previously been calculated regarding shear stress and equivalent on the spud pile body according to the applicable rules. Based on the calculation results using ANSYS, the equivalent stress value in the original design was 357.13 MPa, the shear stress was 87.549 MPa with a deflection value of 38.569 mm and the safety factor was 1.59. Then in the design using solid ASTM A36 it has an equivalent stress value of 129.12 MPa, a shear stress of 31.052 MPa with a deflection value of 14.4 mm and a safety factor of 3.09.
