Abstract

Jacket welhead platform berfungsi sebagai fasilitas produksi yang menopang kegiatan eksplorasi dan eksploitasi minyak dan gas bumi di lepas pantai. Oleh karena itu dalam mendesain jacket platformm kita harus mempertimbangkan beban yang tidak disengaja seperti adanya kemungkinan tabrakan dengan kapal. Struktur boatlanding harus dirancang sedemikian rupa agar mampu menyerap energi akibat tabrakan kapal dengan struktur jacket platform. Pada penelitian ini dilakukan analisis tabrakan kapal dengan struktur boatlanding yang bertujuan untuk mengetahui kekuatan struktur terkait untuk menahan beban yang mungkin terjadi selama benturan kapal pada boatlanding. Pada analisis ini diberiakn beberapa variasi yaitu kecepatan kapal dan posisi datang kapal. Dari analisis statis pada struktur boatlanding dengan tabrakan secara stern didapatkan defleksi= 27,04 cm untuk kondisi tanpa rubber fender. Sedangkan untuk kondisi dengan rubber fender didapatkan defleksi= 5,22 cm. Untuk Tabrakan kondisi broadside didapatkan defleksi= 32 cm untuk kondisi tanpa rubber fender. Sedangkan untuk kondisi dengan rubber fender didapatkan defleksi= 6,91 cm. Pada analisis lokal memodelkan struktur boatlanding dengan rubber fender material Mooney Rivlin. Dari hasil analisis ini didapatkan tegangan von-mises maksimum sebesar 0,17 MPa serta mengalami deformasi maksimum 14,31 mm.

Jacket weirhead platform serves as a production facility that supports offshore oil and gas exploration and exploitation activities. Therefore, in designing a jacket platform, we must consider unintentional loads such as the possibility of a collision with a ship. The boatlanding structure must be designed in such a way as to be able to absorb energy resulting from a ship collision with the jacket platform structure. In this study, a collision analysis of a ship with a boatlanding structure was conducted with the aim of determining the strength of the related structure to withstand the loads that may occur during a ship collision on a boatlanding. In this analysis, several variations were given, namely the ship's speed and the ship's arrival position. From the static analysis of the boatlanding structure with a stern collision, a deflection of 27.04 cm was obtained for conditions without rubber fenders. While for conditions with rubber fenders, a deflection of 5.22 cm was obtained. For broadside collision conditions, a deflection of 32 cm was obtained for conditions without rubber fenders. While for conditions with rubber fenders, a deflection of 6.91 cm was obtained. In the local analysis, the boatlanding structure was modeled with Mooney Rivlin rubber fender material. From the results of this analysis, the maximum von-mises stress was obtained at 0.17 MPa and the maximum deformation was 14.31 mm
