Abstract

Setiap kapal yang beroperasi di laut memiliki resiko kecelakaan yang bisa mengakibatkan kebocoran pada bagian lambung kapal. Perhitungan stabilitas untuk kondisi tersebut diharuskan menggunakan perhitungan damage stability karena perhitungan intact stability dan floodable length telah terbukti tidak lagi aman untuk menjamin keselamatan kapal jika terjadi kebocoran. Objek kapal yang akan dianalisis dalam penelitian ini adalah jenis tongkang (ballastable barge) pengangkut muatan berat struktur bentangan tengah jembatan Holtekamp dari Surabaya ke Jayapura. Referensi yang dipakai untuk menghitung damage stability adalah SOLAS Chapter II-1 Part B-1. Pemodelan kapal dan perhitungan damage stability menggunakan bantuan perangkat lunak Maxsurf. Analisis damage stability dihitung menggunakan pendekatan probabilistik yaitu dengan menghitung peluang kebocoran (p) dan peluang keselamatan setelah kebocoran (s) setiap kompartemen pada kapal. Hasil kali keduanya adalah attained subdivision index (A) yang akan dibandingkan dengan required subdivision index (R) dari SOLAS. Suatu kapal dikatakan memenuhi kriteria damage stability dengan pendekatan probabilistik apabila nilai kumulatif A lebih besar dari R.============ Every vessel operating at sea has a risk of accident that may result in the damage of compartment of the vessel. Stability calculation for this condition is required to use damage stability because the calculation of intact stability and floodable length has proven to be no longer safe in ensuring the safety of the vessel. The vessel analyzed in this research is ballastable barge which transporting the center span of Holtekamp bridge from Surabaya to Jayapura. The reference used to calculate the damage stability is SOLAS chapter II-1 part B-1. Maxsurf software is used to model and to calculate damage stability of the vessel. Damage stability is calculated using probabilistic approach. It is first calculating damage probabilit (p) and survavibility (s) of each compartment along the vessel, then multiply those two to get attained subdivision index (A). The vessel is said to meet the criteria of probabilistic damage stability if the result of combined attained subdivision index (A) is greater than required subdivision index (R) from SOLAS.
