Abstract
Beban akibat tubrukan kapal sangat berpengaruh terhadap integritas suatu
struktur dalam hal ini beban tubrukan kapal menghasilkan Energi Tubrukan, Energi
Serapan, Deformasi Plastis Lokal (Dent), dan Respon Dinamis yang terdiri atas ;
Velocities, Displacement, dan juga Accelerations. Dalam penelitian ini telah dilakukan
Analisa Dinamis Struktur Fixed Jacket PHE 12 Wellhead Platform akibat tubrukan
kapal berbasis resiko. Ship Impact Analysis digunakan dan dilakukan simulasi Monte
Carlo untuk mencari Probability of Failure dari Dent yang dialami oleh struktur PHE
12. Dari analisa Ship Impact dan penilaian Resiko didapatkan peluang kegagalan
sebesar 0,0017779 untuk Conductor, 0,000377 untuk Jacket, dan 0,0000279 untuk
Caisson (Deck Leg). Menurut Matriks Resiko DNV RP G 101 Dent yang didapatkan
termasuk dalam kategori Medium-Risk dan perlu dilakukan tindakan mitigasi dengan
cara penambahan ukuran Member Wall Thickness untuk menekan peluang kegagalan
menjadi Low-Risk.
===========================================================
Impact due to ship collision affects the Integrity of the Structure in this case ship impact
will result in Energy Collision Impact, Energy Absorption, Plastis Local Deformation
(Dent), and Dynamic Response including; Velocities, Displacement, and Accelerations.
In this final project will be carried Risk Based Dynamic Analysis of Fixed Jacket
Structure Due to Ship Collision. Ship Impact Analysis used to obtain Dynamics
Response, Energy Absorption of the Structure and Monte Carlo Simulations to find the
Probability of Failure of Dent experienced by the Structure of PHE 12. Ship Impact
Analysis and Risk Assessment obtained Probability of Failure in about 0.0017779 for
Conductor, 0.000377 for Jacket and 0.0000279 for Caisson (Deck Leg). According to
DNV RP G 101 Risk Matrix, the result of Dent included in the category of Medium-
Risk and mitigation measures need to be done by way of increasing the size of Wall
Thickness Member to suppress the Probability of Failure becomes Low-Risk
