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. Keywords: Bracing, Ladder, KIP, FEA.

Abstract

Offshore building structures are buildings commonly used for oil and gas exploitation activities. The distance is quite far from the coastal area, it is necessary to support transportation facilities for the mobility of offshore structures such as ships and helicopters. To support this mobilization activity, a helicopter landing medium is needed, namely the helideck. This study aims to identify the shock loads that occur on the helideck and calculate the strength of the helideck santos sangu PT.McDermott Indonesia. This study used data from PT.McDermott Indonesia on one of the projects located in Block 16, Bangladesh. The helicopter data used in this study was a jet-A1 type helicopter with a maximum weight of 5307 Kg. The results showed that the value of the helicopter dynamic load on a normal landing was 10348.65 Kg with a working stress of 62163.41 N/mm2 and had an interaction ratio (IR) = 0.35, while for an emergency landing the dynamic load was 1724.75 Kg, the working stress was 103606.45 N/mm2, interaction ratio (IR)= 0.59.
