Abstract

Transportasi jacket platform menggunakan barge memiliki risiko tinggi terhadap kebocoran lambung yang dapat memicu flooding dan penurunan stabilitas. Oleh karena itu, analisis kebocoran sangat krusial dilakukan untuk memastikan keselamatan operasional. Penelitian ini bertujuan untuk mengevaluasi pengaruh kebocoran terhadap stabilitas barge selama proses transportasi jacket platform dengan menggunakan pendekatan penilaian risiko (risk assessment). Metode penelitian melibatkan simulasi lost buoyancy menggunakan perangkat lunak MOSES untuk menganalisis kondisi damage stability akibat flooding pada beberapa skenario kompartemen bocor. Selain itu, analisis stabilitas dilakukan melalui perhitungan kurva GZ dan evaluasi luasan area di bawah kurva lengan pengembali menggunakan metode integrasi numerik Simpson’s rule. Hasil analisis menunjukkan bahwa kebocoran menyebabkan hilangnya gaya apung, penurunan nilai GM efektif, serta berkurangnya lengan dan momen pemulih barge. Dampak tersebut juga terlihat pada penurunan luasan area kurva GZ yang mengindikasikan berkurangnya cadangan stabilitas. Berdasarkan hasil simulasi dan perhitungan, tingkat keselamatan barge sangat dipengaruhi oleh lokasi dan jumlah kompartemen yang mengalami kebocoran. Evaluasi terhadap kriteria stabilitas menunjukkan bahwa pada kondisi tertentu, barge masih memenuhi batas minimum yang disyaratkan, namun pada skenario kerusakan yang lebih kritis, terjadi penurunan performa stabilitas yang signifikan. Dengan demikian, pendekatan risk assessment memberikan gambaran komprehensif dalam menilai risiko kebocoran serta mendukung pengambilan keputusan strategis dalam perencanaan transportasi yang lebih aman.

The transportation of a jacket platform using a barge carries a high risk of hull leakage, which can trigger flooding and a reduction in stability. Consequently, leakage analysis is crucial for ensuring operational safety. This study aims to evaluate the impact of leakage on barge stability during the jacket platform transportation process using a risk assessment approach. The research methodology involves lost buoyancy simulations using MOSES software to analyze damage stability conditions resulting from flooding under various leakage scenarios. Furthermore, stability analysis is conducted through the calculation of GZ curves and the evaluation of the area under the righting arm curve using the Simpson’s rule numerical integration method. The results indicate that hull leakage causes a loss of buoyancy, a reduction in the effective metacentric height (GM), and a decrease in the barge's righting arms and moments. This impact is also reflected in a reduction in the area under the GZ curve, which indicates a diminishing stability reserve. Based on the simulations and calculations, the safety level of the barge is highly dependent on the location and number of compartments affected by the leakage. The evaluation of stability criteria demonstrates that while the barge remains within the required minimum limits under certain conditions, critical damage scenarios lead to a significant decline in stability performance. Thus, the risk assessment approach provides a comprehensive overview of leakage risks and supports strategic decision-making for safer transportation planning.
