PENGARUH VOLUME AIR DI RUANG MUAT TERHADAP STABILITAS KAPAL PENGANGKUT IKAN HIDUP (The Effect of Amount of Water Volume in the Load Space on the Stability of the Vessels Carrying Live Fish)

Abstract

Kapal pengangkut ikan hidup merupakan salah satu alat transportasi yang digunakan selama proses ekspor maupun domestik dan bertujuan untuk mempertahankan ikan dalam keadaan tetap hidup. Muatan utama kapal pengangkut ikan hidup (KPIH) adalah air dan ikan yang berenang bebas di dalamnya dan muatan cair dalam ruang muat dapat bergerak bebas, sehingga terjadi free surface effect (FSE). Paper ini bertujuan untuk menghitung dan mensimulasikan stabilitas kapal pengangkut ikan hidup dan muatan berupa cairan, sehingga dapat diketahui stabilitas kapal berdasarkan muatannya. Analisa stabilitas berdasarkan variasi muatan menggunakan software Maxsurf. Hasil dari analisa stabilitas berdasarkan variasi muatan pada ruang muat 0%,25%, 50%, 75%, 95% dengan variasi volume FOT dan FWT 25%, 50%, 75%, 100% adalah stabilitas kapal tidak layak untuk FOT dan FWT ≤75 % menurut kriteria IMO. The vessels carrying live fish are one of the means of transportation used for the export and domestic processes, and it aims at keeping fish alive. The main loads of these vessels are living fish and water, so the fish can be freely to swim inside the vessel. Therefore, it forms a free surface effect (FSE). This paper aimed at calculating and simulating the stability of the vessels carrying live fish which the cargo on the vessel are liquid, so that the stability of the ship can be determined based on its loads, water and living fish. The stability analysis wa s based on loads variation using Maxsurf Software, so the results obtained were apt with the criteria set by IMO. The results of the stability analysis based on the load variations in the cargo hold were 0%, 25%, 50%, 75%, 95%, and the load variations of fresh water tank and fuel oil tank were 25%, 50%, 75%, 100%. Based on the results of the simulation it was concluded that ships with FWT and FOT load volumes were less than 75% hence vessel stability criteria did not meet IMO standards.
