Abstract

Studi ini mengkaji optimasi desain bracing pada struktur monopod dengan dua support kaki yang digunakan pada platform lepas pantai. Fokus utama dari penelitian ini adalah pada pengaruh variasi konfigurasi bracing terhadap distribusi tegangan dan umur kelelahan struktur. Struktur monopod yang diteliti terletak di perairan dengan kedalaman 53 meter, menggunakan perangkat lunak SACS untuk pemodelan dan analisis. Tiga tipe bracing yang diuji adalah tipe Z, tipe X, dan tipe Inverted V, yang masing-masing dipelajari dari segi efisiensi kekuatan, kemudahan fabrikasi, serta estimasi biaya konstruksi. Hasil analisis menunjukkan bahwa tipe bracing X memiliki distribusi tegangan yang paling merata, sehingga memberikan kinerja struktural terbaik. Selain itu, analisis kelelahan menunjukkan bahwa variasi desain bracing mempengaruhi potensi kerusakan struktural, yang dapat digunakan untuk menentukan desain yang optimal untuk platform lepas pantai di zona barat Kangean. Penelitian ini memberikan kontribusi penting dalam pengembangan desain struktur offshore yang efisien dan ekonomis.

This study examines the optimization of bracing design for a monopod structure with two support legs used on an offshore platform. The main focus of this study is on the effect of various bracing configurations on the stress distribution and fatigue life of the structure. The monopod structure under study is located in waters with a depth of 53 meters, using SACS software for modeling and analysis. The three bracing types tested were Z-type, X-type, and Inverted V-type, each of which was studied in terms of strength efficiency, ease of fabrication, and estimated construction cost. The analysis results showed that the X-type bracing had the most even stress distribution, thus providing the best structural performance. In addition, fatigue analysis shows that variations in bracing design affect the potential for structural damage, which can be used to determine the optimal design for offshore platforms in the western zone of Kangean. This research makes an important contribution to the development of efficient and economical offshore structure design.
