Sampai saat ini penelitian tentang peluncuran kapal menggunakan airbag masih kurang, sehingga informasi ilmiah tentang hal tersebut sangat minim. Beberapa kendala yang ada dalam praktek lapangan antara lain kesulitan memprediksi perilaku kapal saat diluncurkan dengan airbag, kesulitan menginvestigasi kondisi-kondisi kritis peluncuran kapal serta belum tersedia petunjuk operasional keselamatannya. Penelitian ini mengkaji peluncuran kapal menggunakan airbag dengan menggunakan metode uji model dengan melakukan studi sensitivitas beberapa parameter yang berpengaruh pada peluncuran kapal. Analisis dilakukan pada beberapa kondisi ekstrim yaitu kondisi terjadinya benturan, kondisi pada sudut pitch maksimum, dan kondisi pada freeboard minimum. Melalui uji model, dapat diketahui perilaku gerakan kapal saat diluncurkan dengan menggunakan airbag, serta dapat diketahui tingkat keselamatan peluncuran kapal
The fin stabilizer is located on the hull of the ship, one left and one right, which is connected to the fin stabilizer control room as a tool to respond to excessive ship rolling in both directions. In this study, we will analyze the ship resistance due to the addition of a fin stabilizer type Naca 0013 on patrol boats with variations in angles of 0°, 5°, 10°, 15° with speed variations of 25 - 30 knots. Calculation of ship resistance using Maxsurf modeler software and Numeca fine marine. In the early stages of validating the model that has been tested on a towing tank with a patrol boat design made using the Maxsurf modeler and Numeca fine marine. Validation results with a maximum error of 2.38% maxsurf software and 2% Numeca software. There was an increase in resistance due to the fin being installed at an angle of 0° by 0.56% - 1.22%, at an angle of 5° by 2.26% - 3.75%, at an angle of 10° by 6.48% - 9.49%, at an angle of 15° by 13.92% - 18.79 % of the total drag of the ship.
ABSTRAKLarnbung timbul dipertimbangkan sebagai elemen yang penting dalam keselarnatan kapal. Sehingga untuk menjaga kelayakan laut, kapal harus merniliki beberapa daya apung cadangan, seperti volume diatas luasan garis air dan dibawah geladak kedap air. BKI sebagai badan klasifikasi nasional merniliki peranan penting dalarn penentuan larnbung timbul melalui kegiatan survai dan sertifikasi lambung timbul kapal. Studi awal mengenai lambung timbul dan koreksi tinggi haluan dilal
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
