ANALISIS KEKUATAN PENGARUH MODEL BRACING TERHADAP PONDASI KATROL LADDER PADA KAPAL ISAP PRODUKSI (KIP)

Abstract

With the use of the bracing model that was built during the building of the ladder-pulley foundation, this research intends to analyze the strength of the ladder-pulley foundation on the Kapal Isap Produksi (KIP). Finite element analysis (FEA) and modeling with the Ansys software were used in the investigation. The 58 m length of the actual ladder is considered when creating the model. Then, create each model of a diagonal brace and an x-bracing specifically for the pulley foundation. After that, a special diagonal brace and an x-bracing model were developed, respectively, for the pulley foundation's building. The load acting on the ladder for the two versions is the same: 1.42 x 105 N for the pipe and mud, 0.57 x 105 N for the cutter, and 0.67 x 108 Nmm for the cutter torque. According to the analysis's findings, the diagonal brace model's strut component experiences the highest level of stress, measuring 57.32 N/mm2, whereas the x-bracing model's greatest stress value is 25.44 N/mm2. These findings suggest that, to reduce structural failure in the ladder pulley area, it is preferable to use x-bracing construction for the brace design put there. This is because it has a lower minimum stress value than the diagonal brace model.
