Abstract

Analisa perilaku respon gerak struktur jacket fixed platform yang dilakukan pada struktur Bekapai BQ Platform didasari oleh adanya isu ketidaknyamanan para personil yang bekerja di atasnya. Gaya tubrukan dari kapal yang akan bersandar mengakibatkan struktur mengalami perpindahan cukup besar dari posisi awal. Yang membahayakan karena perpindahan struktur sangat terasa pada daerah maindeck terutama pada livingquater yang merupakan tempat tinggal personil. Analisa respon gerak dinamis struktur yang akan ditinjau adalah nilai defleksi pada beberapa joint penting setelah mendapat pengaruh tubrukan kapal pada boatlanding struktur. Respon dinamis struktur didapatkan dari hasil analisa berbasis time domain dengan tujuh variasi arah datang kapal yang akan bersandar. Hasil yang di dapatkan menunjukan bahwa struktur benar mengalami perpindahan yang cukup besar. Untuk perpindahan defleksi struktur paling tinggi terjadi saat tubrukan kapal dengan kecepatan 1 knot yang terkena pengaruh beban gelombang arah 2250. Dapat disimpulkan bahwa tabrakan kapal akan memberikan efek perpindahan yang sangat besar pada struktur, tetapi masih dapat diterima. Namun perlu dilakukan adanya analisa lanjutan guna menambah kekuatan struktur agar dapat menerima beban tabrakan yang lebih besar. =============================================================================================== Dynamic response behavior analysis on the fixed platform jacket structure performed on BQ Platform Bekapai structure constituted by the issue of personnel’s inconvenience while working on it. The collision force of ship docking process is generating the structure to experience significant amount of displacement from the initial position. It’s dangerous because the displacement of the structure is felt in the area around the deck, especially at living quarter which is personnel’s home. Analysis of dynamic motion response of the structure that is being calculated is the value of deflection on several important joint after receiving vessel collisions influence of boat landing structure. The dynamic response of the structure obtained from the analysis of time domain with seven variations of ship docking direction. The results obtained show that the structure actually having a fairly large displacement. For the highest displacement deflection occurs when the structure of the ship collision at a speed of 1 knot affected by wave loads towards 2250. It can be concluded that the ship collision will provide a very large displacement effect on the structure, but still acceptable. However, further analysis must be conducted to increase the strength of the structure in order to receive a larger collision load.
