Abstract

The paper discusses the significance of different types of skegs in a barge toward the pressure, fluid velocity and the ship?s total resistance. There are three kinds of skeg configurations: barge without skegs, skegs without deflection, and skegs with deflection. The barge was towed with forward speed were ranging across 3 knots ? 9 knots. The simulations were conducted using an open-source RANS (Reynold Averaged Numerical Simulation) CFD code Open-FOAM. The simulations show that the skegs raise the barge?s resistance. The skegs with deflection have a bigger resistance amplification compared to skegs without deflection.

Abstract

Jumlah sampah yang dibawa ke Tempat Pembungan Akhir (TPA) Manggar Balikpapan saat ini mencapai 305 m3 perharinya. Lebih dari itu, sering pula dijumpai sampah-sampah yang masih tersebar di muara-muara sungai,pelabuhan dan kawasan perairan lain yang tidak diketahui jumlahnya salah satunya di Sungai Klandasan Hilir. Maka masalah yang muncul adalah bagaimana mendesain suatu kapal yang dapat mengatasi penumpukan sampah di perairan sungai dan berapa ukuran utama yang sesuai untuk perairan sungai diKalimantan. solusi yang dapat digunakan untuk mengatasi penumpukan sampah yang ada disungai yaitu dengan menggunakan bantuan Trash Skimmer Boat. Work Boat ini adalah salah satu jenis dari kapal khusus yang difungsikan untuk melakukan pengambilan sampah perairan baik sungai, danau, laut maupun kanal. Menggunakan metode Parent Design Approach dan dengan bantuan Software Maxsurf maka diperoleh ukuran utama sebesar LOA = 3 m, B =  2 m, T = 0,37 m, H = 0,7 m, B1 = 0,962 m, dan v = 6 knots. Bentuk dasar dari Trash Skimmer Boat ini berlambung pontoon catamaran yang dilengkapi dengan bak sampah dengan kapasitas 1 m3 dan  Setelah dilakukan survey data sampah, disarankan kapal ini dioperasikan sekali dalam seminggu selama 1 jam dengan fasilitas tambahan yaitu 1 bak penampungan sampah dan 1 unit  mini portable crane dengan kapasitas angkut sebesar 300 kg yang diletakkan pada dermaga titik akhir penampungan sampah dari sungai. Kata kunci: Sampah,Sungai Klandasan Hilir, Trash Skimmer Boat

Abstract

With the high demand and market growth for composite boats, there is a competition to design a high-quality ship which leads to thinner boat?s hull structure. To meet this objective, a highly accurate and computationally fast calculation for composite structure is needed. In ship's structure the most used configuration of the stiffeners is by using grillage. However, most of the theory of the grillage is designated for steel structure. There is a gap between steel and composites for grillage theory which will be modified especially for the deflection. There are two general methods that used in this analysis, Navier Grillage theory as the analytical method and Finite Element Analysis as the benchmark tools. To develop analytical method of composite grillages, the current method were investigated by comparing the analytical results and FEA. Two composites with high difference in Young Modulus were analyzed and the results shows that there are significant difference of results with two previous method. The deflection results of two method were analyzed with every composite elastic properties of E-Glass. Empirical equation were developed from the relation between deflection graph of two methods and composite to increase the accuracy of Navier Grillage theory for E-Glass composites grillage.
