Abstract

Penelitian ini bertujuan untuk mengevaluasi tingkat risiko tabrakan kapal terhadap fasilitas Single Point Mooring (SPM) di Terminal Lawe-Lawe menggunakan pendekatan kuantitatif. Analisis dilakukan dengan menghitung frekuensi tabrakan berdasarkan variasi kecepatan kapal (1 knot, 0,5 knot, dan 0,25 knot) dan mengestimasi dampak menggunakan energi tumbukan sebagai parameter utama konsekuensi. Nilai frekuensi tabrakan masing-masing adalah 0,004, 0,002, dan 0,001 kejadian per tahun, yang seluruhnya dikategorikan sebagai "Unlikely" menurut standar ABS. Sementara itu, konsekuensi energi tumbukan sebesar 24.169 kJ, 6.042 kJ, dan 1.511 kJ pada masing-masing kecepatan dikategorikan sebagai “Negligible”, berdasarkan pengelompokan tingkat dampak energi yang umum digunakan dalam pendekatan QRA (Quantitative Risk Assessment), di mana nilai energi di bawah 100.000 kJ termasuk dalam kategori konsekuensi rendah (Negligible Consequence). Hasil pemetaan ke dalam matriks risiko 5x5 menunjukkan bahwa seluruh skenario berada pada tingkat risiko rendah (Low). Meskipun demikian, tindakan pencegahan tetap direkomendasikan sesuai prinsip ALARP (As Low As Reasonably Practicable), seperti penetapan batas kecepatan, sistem deteksi dini, serta pelatihan keselamatan awak kapal. Penelitian ini menunjukkan bahwa pendekatan kuantitatif berbasis frekuensi dan energi dampak dapat memberikan dasar yang kuat dalam pengambilan keputusan keselamatan operasional di fasilitas offshore.

This study aims to assess the risk of ship collision with the Single Point Mooring (SPM) facility at the Lawe-Lawe Terminal using a quantitative risk assessment approach. The analysis involves calculating the collision frequency based on different vessel approach speeds (1 knot, 0.5 knot, and 0.25 knot), and estimating the impact consequence using collision energy as the primary parameter. The resulting collision frequencies are 0.004, 0.002, and 0.001 incidents per year, respectively—all classified as "Unlikely" according to ABS standards. Meanwhile, the corresponding impact energies of 24,169 kJ, 6,042 kJ, and 1,511 kJ are categorized as “Negligible.”, based on consequence classification commonly used in Quantitative Risk Assessment (QRA) approaches, where energy impacts below 100,000 kJ fall into the “Negligible Consequence” category. Risk mapping using a 5×5 matrix places all scenarios within the "Low" risk category. Despite the low level of risk, preventive measures are still recommended following the ALARP (As Low As Reasonably Practicable) principle, such as speed restrictions, early warning systems, and crew safety training. This study demonstrates that a quantitative approach based on frequency and impact energy provides a robust foundation for operational safety decision-making in offshore facilities.
