Abstract
Jacket platform adalah struktur bangunan yang dibangun di perairan dangkal untuk mendukung kegiatan eksplorasi dan produksi minyak dan gas. Ketika melakukan perancangan struktur harus memenuhi standar dan codes yang telah ditetapkan oleh lembaga yang memiliki bidang di bangunan laut agar terhindar dari kegagalan pada struktur yang diakibatkan dari berbagai beban yang mengenai struktur. Pada fabrikasi struktur akan mengalami proses lifting, karena lifting merupakan salah satu tahap paling penting. Pada melakukan geometri struktur, rancangan mengacu pada standar API RP-2A WSD dengan menggunakan software SACS. Bagian yang dimodelkan adalah bagian dari main deck yang mempunyai panjang 24.4 m dan lebar 13.2 m. Kemudian berat total dari struktur main deck adalah 101.3 ton. Analisis ini menggunakan tiga variasi sudut sling, yaitu sudut 30°, sudut 45°, dan sudut 60°. Untuk dimensi padeye Sudut 30°, sudut 45°, dan sudut 60° memiliki diameter hole padeye masing-masing sebesar 96 mm, 88 mm, dan 84 mm. Tegangan dan UC terbesar terdapat pada sudut 30°, yaitu 25023.96 psi dan UC 0.81 jika ditinjau dari hole padeye tegangan atau UC terbesar terdapat pada sudut sudut 30° juga, yaitu 19569.3 psi dan UC 0.78. Tegangan pada padeye dijadikan variabel untuk mencari keandalan yang terjadi pada padeye. Didapatkan Probability of Failure (PoF) pada padeye pada sudut 30°, sudut 45°, dan sudut 60° sebesar 8.53%, 4.75%, dan 1,36%.

Jacket platform is a building structure built in shallow waters to support oil and gas exploration and production activities. When designing a structure, it must meet the standards and codes set by institutions that have a field in marine buildings in order to avoid failure of the structure caused by various loads on the structure. The fabrication of the structure will undergo a lifting process, because lifting is one of the most important stages. In doing structural geometry, the design refers to the API RP-2A WSD standard using SACS software. The modeled part is part of the main deck which has a length of 24.4 m and a width of 13.2 m. Then the total weight of the main deck structure is 101.3 tons. This analysis uses three variations of sling angles, namely 30° angle, 45° angle, and 60° angle. For the padeye dimensions, angle 30°, angle 45°, and angle 60° have padeye hole diameters of 96 mm, 88 mm, and 84 mm, respectively. The largest stress and UC are found at an angle of 30°, which is 25023.96 psi and UC 0.81 when viewed from the padeye hole, the largest stress or UC is also found at an angle of 30°, which is 19569.3 psi and UC 0.78. The stress on the padeye is used as a variable to find the reliability value that occurs on the padeye. The Probability of Failure (PoF) value on the padeye at an angle of 30 °, an angle of 45 °, and an angle of 60 ° is 8.53%, 4.75%, and 1.36%.
