Abstract

Kapal Multipurposess Vessel 3500 GT didesain pada bagian deck buritan dapat dimuat kendaraan hovercraft, dimana saat loading-unloading hovercraft, draft bagian buritan kapal Multipurposess Vessel 3500GT harus lebih rendah dari bagian haluan, sehingga mengakibatkan kondisi trim by stern. Untuk itu dibutuhkan sistem air balas khusus terhadap kondisi seperti ini. Dalam penelitian ini menggunakan metode perancangan dan pembuatan model serta sistem interface operasional pada saat melakukan ballasting/deballasting kapal. Perhitungan komponen utama meliputi perhitungan pipa utama, HeadPompa, Aliran fluida yang dibutuhkan, serta pemilihan komponen . didapatkan hasil Kapastias pompa yang dibutuhkan adalah 0.384 m3/s, Headloss pompa sebesar 16 m , dan diamter pipa utama sebesar 15,9 inch. pemilihan Pipa disesuaikan dengan Japanese Industrial Standard, maka didapat pipa dengan SCH 40, nominal 400A, outside diameter 406,4 mm, dan ketebalan 12,7 mm. Setelah itu didapatkan Pompa yang sesuai dengan spesifikasi yaitu merek DAB tipe KDN 300-330 / 325 dengan head maksimal 18 m dan kapasitas 1400 m3/hr. Setelah pembuatan sistem control air balas pada Aplikasi Labview, dilakukan validasi hasil menggunakan Aplikasi Maxsurf, terdapat perbedaan dari beberapa hasil trim angel by stern . Adapun hasil dari sudut trim angel by stern pada aplikasi labview secara berurutan dari scenario 1-4 adalah sebesar 00, 0.20,0.40, 0.50, sedangkan pada Aplikasi Maxsurf secara berurutan dari scenario 1-4 adalah 00, 0.1910, 0.250, 0.330. Dari hasil tersebut terdapat perbedaan signifikan pada skenario 3 dan skenario 4 .

The Multipurpose Vessel 3500 GT is designed on the stern deck to accommodate hovercraft vehicles, where during loading-unloading hovercraft, the draft of the stern of the Multipurpose Vessel 3500GT must be lower than the bow, resulting in a trim by stern condition. For this reason, a special ballast water system is needed for these conditions. In this study, the method of designing and modeling as well as operational interface systems when ballasting/deballasting ships is used. The calculation of the main components includes the calculation of the main pipe, pump head, required fluid flow, and component selection. The results obtained that the required pump capacity is 0.384 m3/s, the pump headloss is 16 m, and the primary pipe diameter is 15.9 inches. Pipe selection is adjusted to the Japanese Industrial Standard, so the pipe is obtained with SCH 40, nominal 400A, outside diameter 406.4 mm, and thickness 12.7 mm. After that, a pump that meets the specifications is obtained, namely the DAB brand type KDN 300-330 / 325 with a maximum head of 18 m and a capacity of 1400 m3/hr. After making the ballast water control system on the Labview Application and validating the results using the Maxsurf application, there are differences from some of the trim angel by stern results. The results of the trim angel by the stern angle in the Labview application sequentially from scenarios 1 to 4 are 00, 0.20,0.40, 0.50, while in the Maxsurf application sequentially from scenarios 1 to 4 is 00, 0.1910, 0.250, 0.330. From these results, there are differences between Scenario 3 and Scenario 4.
