Abstract

Terminal Kijing diproyeksikan menjadi kawasan pelabuhan internasional terbesar di Kalimantan. Salah satu yang sudah dilayani di terminal kijing adalah dermaga curah cair. Saat beroperasi dan bersandar di dermaga tentunya kapal tanker memerlukan sistem tambat. Penelitian ini melakukan identifikasi risiko menggunakan fault tree analysis dan analisis risiko secara semi-kuantitatif dengan menggunakan bowtie analysis pada tali tambat putus. Setelah dianalisis, diprediksi terjadi 20 basic event yang menyebabkan tali tambat putus. Perhitungan minimal cut set dilakukan dan menghasilkan basic event tali dengan kondisi buruk dengan probabilitas terbesar 1,5047 x 10-3. Penilaian risiko likehood dan severity dilakukan dan menghasilkan 14 risiko termasuk moderate to high, dan 6 risiko termasuk moderate. Namun, 5 diantara 14 risiko moderate to high memiliki kodesifikasi angka lebih tinggi yaitu dengan risk value 19. Lima risiko tersebut adalah arus yang terlalu deras, gelombang yang terlalu tinggi, pretension yang terlalu besar, perbedaan pretension antar tali, dan tali dengan kondisi buruk. Dilakukan juga analisis risiko secara kuantitatif pada salah dua basic event tertinggi yaitu, gelombang yang terlalu tinggi yang mendapatkan probability of failure 9 x 10-3 dan pretension yang terlalu besar yang mendapatkan probability of failure 4 x 10-3 . Dilakukan juga mitigasi risiko secara semi-kuantitatif (bowtie analysis) dan mitigasi secara kuantitatif dengan dengan menambah diameter tali, menambah jumlah tali, dan membesarkan pretension. Setelah dimitigasi, penilaian terhadap risiko-risiko tersebut mengalami penurunan menjadi 9 yang termasuk moderate, dan 11 yang termasuk moderate to low.

The Kijing Terminal is projected to become the largest international port area in Kalimantan. One that has been served at the kijing terminal is the liquid bulk dock. When operating and leaning on the dock, of course, tankers requires a mooring system. The study identified risks using fault tree analysis and semi-quantitative risk analysis using bowtie analysis on mooring ropes failure. After analysis, 20 basic events were predicted to occur that caused the mooring line failure. A minimum cut set calculation was performed and resulted in a poor condition rope basic event with the greatest probability of 1.5047 x 10-3. The risk assessment of likehood and severity was conducted and resulted in 14 risks including moderate to high, and 6 risks including moderate. However, 5 of the 14 moderate to high risks have a higher codification number with a risk value of 19. The five risks are too heavy current, too high waves, too large pretension, difference in pretension between ropes, and ropes in poor condition. Quantitative risk analysis was also carried out on one of the two highest basic events, namely, too high waves that get a probability of failure of 9 x 10-3 and too large pretension that gets a probability of failure of 4 x 10-3. Semi-quantitative risk mitigation (bowtie analysis) and quantitative mitigation were also carried out by increasing the rope diameter, increasing the number of ropes, and increasing the pretension. After mitigation, the assessment of these risks has decreased to 9 which are included as moderate, and 11 which are included as moderate to low.
