KAJIAN DAMAGE STABILITY PADA STUDI KELAYAKAN DESAIN KAPAL BARGE PENAMBANG TIMAH DENGAN PENDEKATAN METODE NUMERIK

Abstract

Nearly 90% of ship accidents or ship sinking are caused by leakage. Tin Mining Barge Vessel is an interesting research object because there are various challenges that are being faced in designing, arranging, and constructing tin mining vessels, especially regarding stability studies when a ship has a leak. Tin Mining Barge Vessel has a displacement (Δ) = 3025 tons, length (LoA) = 68 m, Width (B) = 17 m, High (H) = 5 m, Sarat (T) = 3 m. The configuration of the stability simulation of The Tin Mining Barge Vessel uses a variation of 1 intact case and 15 damage cases where simulated compartments around the ship's hole have leakage and then calculated its stability value and compared the results with IMO Code A.749 (18) Ch 3 and IMO regulations SOLAS requirements Chapter II Part B-1. From the results of the study, it can be concluded that the ship becomes unstable if there is a leak in the compartment on one side of the hole of the ship such as the Void 3 and 4 compartments at Portside (P) or on the Starboard (S). Overall, it can be concluded that the Tin Mining Barge Vessel will be instability when a leak occurs. The solution is conducted by adding the installation of a watertight length with a distance of 1200 mm in the compartment: Void 3 (P), Void 4 (P), Void 3 (P), and Void 4 (S).
