Abstract

Pilot Project Energy Laut Hibrid untuk masyarakat nelayan menggunakan ponton tripod siku-siku berbasis hybrid. Analisis hidrodinamika dilakukan melalui simulasi Computational Fluid Dynamic (CFD) dan pengujian model Detail Engineering Design (DED) di Laboratorium Hidrodinamika Indonesia (LHI). Namun, analisis struktur tidak dilakukan saat proses prototipe, menyebabkan pemilihan material untuk frame ponton kurang tepat. Penelitian ini bertujuan melakukan analisis struktur pada frame ponton tripod hybrid, termasuk re-desain dan perbandingan kekuatan antara desain existing dan modification. Analisis dilakukan dengan metode Inplace Analysis menggunakan Software SACS V15.1 untuk mendapatkan nilai Unity Check dan sebaran tegangan. Hasil analisis menunjukkan bahwa nilai Unity Check pada model existing untuk tipe gelombang Airy wave01, Airy wave02, Stokes wave01, dan Stokes wave02 adalah 0.508, 0.498, 0.509, dan 0.5 secara berturut-turut. Sedangkan, nilai Unity Check pada model modification untuk tipe gelombang Airy wave01, Airy wave02, Stokes wave01, dan Stokes wave02 adalah 0.827, 0.81, 0.827, dan 0.813 secara berturut-turut. Terjadi kenaikan nilai Unity Check sebesar 63% pada model modification, dengan shear stress terbesar terjadi pada member A5-1-A5-2 pada kedua model. Namun masih memenuhi standard API RP 2A-WSD. Model modification memiliki bobot 21% lebih ringan dibandingkan model existing, dengan nilai Z shear stress meningkat 63% untuk kedua tipe gelombang Airy dan Stokes.

The Pilot Project Energy Laut Hibrid for coastal communities utilizes a hybrid-based tripod pontoon structure. Hydrodynamic analysis was conducted using Computational Fluid Dynamic (CFD) simulations and Detail Engineering Design (DED) testing at the Hydrodynamics Laboratory of Indonesia (LHI). However, structural analysis was not performed during the prototyping process, leading to suboptimal material selection for the pontoon frame. This research aims to conduct structural analysis on the tripod pontoon frame, including redesign and a comparison of strength between the existing and modified designs. Inplace Analysis using Software SACS V15.1 was employed to obtain Unity Check values and stress distribution. The analysis revealed that the Unity Check values for the existing model, with Airy wave01, Airy wave02, Stokes wave01, and Stokes wave02, were 0.508, 0.498, 0.509, and 0.5, respectively. In contrast, the Unity Check values for the modified model, with Airy wave01, Airy wave02, Stokes wave01, and Stokes wave02, were 0.827, 0.81, 0.827, and 0.813, respectively, indicating a 63% increase in Unity Check for the modified model. The largest shear stress was observed on member A5-1-A5-2 in both models, which still complies with the API RP 2A-WSD standard. Additionally, the modified model was 21% lighter than the existing model, with Z shear stress increasing by 63% for both Airy and Stokes wave types.
