Kajian Eksperimental Peluncuran Kapal Menggunakan Air Bag

Abstract

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

Technical and Economic Analysis of Ship Launching with Slipway and Airbag KM. Sabuk Nusantara 72 in PT. Janata Marina Indah Shipyard Semarang

“…The consideration in launching with this method is the buoyancy and drag force, which allows greater than the bow. The ship launching process requires a substantial investment to plan the launch area (Fitriadhy & Malek, 2017;Irawanto et al, 2019). As with the slipway system, a relatively expensive initial investment will be required to construct a skate structure with the track (Xiao et al, 2020).…”

“…Previous research has shown that there have not been many investigations on slipway and airbag launching methods comparison. There are still a few references on both methods comparison (Fitriadhy & Malek, 2017;Irawanto et al, 2019). In previous research, there are actual conditions in the field.…”

“…There is a form of failure that occurs, such as an airbag erupting, resulting in the ship's overturning in the launching process. To reduce the launch failure risk, analysis is necessary for the form of technical and economic studies (Fitriadhy & Malek, 2017;Irawanto et al, 2019). The need for a more in-depth analysis to support the success of the launching process and ship safety related to the success in the launching process and ship safety (Yamagami et al, 2006).…”

“…Besides, a study entitled "experimental study of ship launching using airbags" by Irwanto compares launch calculations with DGPS measurements and video recording results. The analysis results show that the value is quite significant, especially in the projection of the position of the stopping of the ship due to uncertainties related to water resistance (Irawanto et al, 2019). Compared to the graving dock launching method, this method has the advantage of lower initial investment costs.…”
