Abstract

Proses sandar kapal di pelabuhan memiliki risiko terjadinya tubrukan antara lambung kapal dengan struktur *jetty* yang dapat menyebabkan kerusakan pada kedua struktur. Salah satu upaya untuk mengurangi dampak tubrukan adalah penggunaan *fender* sebagai media penyerap energi. Penelitian ini bertujuan menganalisis pengaruh variasi sudut tubrukan terhadap respons struktur lambung kapal dan *jetty* pada kondisi menggunakan *fender* maupun tanpa *fender* melalui simulasi numerik menggunakan ANSYS Explicit Dynamics. Model struktur kapal, *jetty*, dan *fender* dibuat berdasarkan dimensi yang telah ditentukan dengan material baja struktural untuk kapal, beton untuk *jetty*, dan karet neoprena (*neoprene rubber*) untuk *fender*. Simulasi dilakukan pada variasi sudut tubrukan 0° dan 3° dengan kecepatan kapal yang dijaga konstan. Parameter yang dianalisis meliputi tegangan maksimum, deformasi total, gaya reaksi, serta energi tubrukan yang terjadi selama proses kontak. Hasil simulasi menunjukkan bahwa variasi sudut tubrukan memengaruhi distribusi tegangan dan deformasi pada struktur. Penggunaan *fender* mampu menyerap sebagian energi tubrukan sehingga menurunkan nilai tegangan dibandingkan kondisi tanpa *fender*. Sebaliknya, pada kondisi tanpa *fender*, beban tubrukan diterima secara langsung oleh struktur sehingga menghasilkan konsentrasi tegangan yang lebih tinggi dan meningkatkan potensi kerusakan pada lambung kapal maupun *jetty*. Dengan demikian, pemasangan *fender* terbukti efektif dalam meningkatkan keselamatan proses sandar kapal serta mengurangi risiko kerusakan struktur akibat tubrukan.

The ship berthing process at ports carries the risk of collisions between the ship's hull and the jetty structure, which may cause damage to both structures. One of the methods used to mitigate the impact of such collisions is the installation of fenders as energy-absorbing devices. This study aims to analyze the effect of collision angle variations on the structural response of the ship's hull and the jetty under conditions with and without fenders using numerical simulations in ANSYS Explicit Dynamics. The structural models of the ship, jetty, and fender were developed based on predetermined dimensions using structural steel for the ship, concrete for the jetty, and neoprene rubber for the fender. Simulations were conducted for two collision angle variations, namely 0° and 3°, while maintaining a constant ship velocity. The analyzed parameters included maximum stress, total deformation, reaction force, and collision energy generated during the contact process. The simulation results indicate that variations in the collision angle significantly affect the stress distribution and structural deformation. The use of a fender effectively absorbs a portion of the collision energy, thereby reducing the maximum stress compared with the condition without a fender. In contrast, under the no-fender condition, the collision load is transmitted directly to the structure, resulting in higher stress concentrations and increasing the potential for structural damage to both the ship's hull and the jetty. Therefore, the installation of fenders has been proven effective in improving the safety of the berthing process and reducing the risk of structural damage caused by ship collisions.
