Biofouling on ship hulls increases drag, fuel consumption and environmental impact. This study uses Computational Fluid Dynamics (CFD) to simulate biofouling roughness effects the FAO1 fishing vessel, analysing changes in hydrodynamic resistance. Simulations, validated against experimental data, considered varying levels vessel speeds. The results show that increased raises both total frictional resistance, especially at higher speeds, emphasising smooth hull maintenance for efficiency....
Kabupaten Batang terletak di pantai utara Jawa Tengah dimana wilayah pesisir kabupaten ini terdapat potensi yang dapat dikembangkan menjadi aset berharga bagi bangsa yaitu para pembuat kapal tradisional. Sebagian besar pengrajin kayu tradisional dalam pembangunan konstruksi tanpa melalui proses rancang bangun secara modern. Dalam pelaksanaannya, baik tipe ataupun bentuk dibangun, berdasarkan pengalaman kapal-kapal pernah dibuat sebelumnya dan perhitungan penggambaran terlebih dahulu,...
Kepulauan Seribu merupakan kepulauan yang terletak di sebelah utara Jakarta. Sejak tahun 2000-an pemerintah telah mengarahkan sektor perikanan dan kelautan sebagai andalan sumber perekonomian. Menurut informasi dari Pemerintah Administrasi menjelaskan bahwa produksi didapatkan 1.584 ton tangkap ikan laut 798,14 hasil budidaya (Jakarta dalam angka 2012). Berdasarkan observasi Seribu, disini belum ada kapal khusus digunakan untuk mengangkut ikan, selama ini proses pengangkutan dijadikan satu...
LNG ISO tank containers are a solution for bulk liquefied natural gas (LNG) delivery to the outer islands of Indonesia that not connected pipeline network. The design an frame must consider two critical parameters, strength/rigidity and weight saving, which affect operational performance distribution process. current investigation aims numerically optimize structural 40 ft mini carrier operation using topology optimization framework. Two solutions used in framework: reducing strain energy...
Pantai Amed yang terletak di Bali Timur merupakan destinasi wisata populer karena keindahan pantainya dan beach club menarik. Sebagai upaya inovatif untuk mendukung ekonomi lokal, dibangunlah floating dengan konsep futuristic kawasan ini. Floating ini dirancang menarik lebih banyak wisatawan sesuai peraturan daerah Kabupaten Karangasem dalam pengembangan infrastruktur. Desainnya mempertimbangkan kapasitas operasional darat menggunakan perhitungan displacement, deadweight, lightweight. Ukuran...
Delays that occur in the KMP Dharma Rucitra 1 ship refurbishment project have an impact on MT Trikasa 17 project, so work must be accelerated order not to exceed contract. This study aims overcome delays by finding most optimal time acceleration value and minimum cost. The cost trade off method is often used scheduling repair of two or more units simultaneously optimize cost, this considered able problems occur. Based list main schedule data, critical trajectory productivity values each job...
Floating dock merupakan bangunan air sebagai tempat reparasi kapal yang dinilai cukup efisien dalam pembangunannya karena tidak membutuhkan dana terlalu mahal. Di sektor indusrti perkapalan kota tegal sudah memiliki galangan dan berkembang. Ide perancangan floating ini dirancang alternatif baru pelayanan kapal. Perancangan juga memperhatikan dengan detail kapasitas – pernah melakukan repararasi di sekitar Kota Tegal agar ditemukan ukuran utama tepat. Dari Kapasitas ada berdasarkan metode...
A navigation buoy is a navigational aid tool that very important in supporting the safety of shipping lanes. However, buoys are often lost and damaged, caused by several factors, one which being hit ship. Therefore, it essential to conduct this research determine damaging effect on after vessel effectiveness using medium-density polyethylene material structure. This study uses finite element numerical simulation method making three variations speed, as well two angle impact, namely 0° 45°,...
Not only the circle hollow pipe but also rectangular pipes are used on offshore structure. In this study, bending moment was given at both end of pipe. The strength buckling can be reduced by increasing length. models varying from a/b = 1, 2, 4; a/t 10, 15, 20 and L/a 20. On which is have larger rectangle area (a/b), deformation. Vice versa smaller as though 2 4 conclude that one then oval deformation large too. will increase with decreasing mid span increase. decrease a/t. in elastic state...
Pembuatan perahu katamaran berkulit plastik HDPE akan memberikan pengaruh secara teknis maupun ekonomis. Faktor berat dan desain berkorelasi langsung terhadap hambatan perubahan kapasitas muatnya. Tujuan dari penelitian ini adalah melihat manfaat yang diperoleh penggunaan bahan alternatif dimaksud. Penelitian dilakukan dengan cara melakukan observasi, analisis berdasarkan rumus empiris, penilaian kriteria ditetapkan dalam perencanaan kapal katamaran. Hasil analisa menunjukkan terjadi...
Kelebihan kapasitas muat (overload) dapat menyebabkan kecelakaan atau tenggelamnya kapal. Batas dalam eksploitasi kapal seringkali tidak dihiraukan demi meraup untung besar. Penelitian ini bertujuan untuk melihat batas overload yang masih aman pada penyeberangan di Pelabuhan Kali Adem-Kepulauan Seribu. Metode digunakan adalah memberikan simulasi tambahan muatan hingga tertentu dari sarat maksimum desain dimana akan diperoleh kondisi layak. Standar IMO Resolution MSC.267 (85) dan Nordforsk...
The use of HDPE plastic as a result packaging chemicals subtitution for wooden shell of boat hull provides several advantages both technically and economically. Stock material is relatively abundant, its price cheap, long service life. method used in the manufacture boat, include preparation materials processing, assembly, last finishing. Planning manufacturing procedures governed by criteria which refers to Basic Ship Theory. end after ship was completed providing technical form increase...
