ANALISIS KEKUATAN PONDASI TOWING WINCH KAPAL AHTS 7600 HP DENGAN FEM

Abstract

This study analyzes the structural strength of the towing winch foundation on an AHTS 7600 HP vessel due to changes in tensile strength specifications, employing the Finite Element Method (FEM). The change in specification occurs as a result of a towing winch vendor replacement during the ship construction phase, which has the potential to affect the foundation’s design and strength. FEM simulations are conducted to evaluate the structural response under both static and dynamic loading up to the maximum load limits. The analysis results indicate that, under various loading scenarios according to the new specification, the maximum stress experienced by the foundation remains below the safety factor as stipulated by BKI regulations. This study concludes that the existing foundation design is still capable of withstanding the loads resulting from the specification change and provides design improvement recommendations to ensure that the safety factors remain fulfilled during offshore operations.
