Abstract

Kapal tanker minyak memainkan peran vital dalam perekonomian dunia karena berfungsi sebagai sarana transportasi utama mengangkut sumber energi yang paling banyak digunakan di dunia, yaitu minyak. Kapal tanker dengan ukuran lebih dari 5,000 DWT wajib dilengkapi dengan struktur double bottom berdasarkan MARPOL 73/78 dan Common Structural Rules. Struktur tersebut mengurangi volume ruang muat secara signifikan dan juga menambah berat struktur kapal. Maka dari itu, diperlukan penelitian untuk mengoptimalkan desain double bottom pada kapal tanker untuk memaksimalkan volume ruang muat dan meminimalkan berat struktur kapal. Berbagai metode optimisasi dapat digunakan untuk menemukan solusi masalah yang paling optimal salah satunya adalah brute force search method. Penelitian ini akan dilakukan dalam dua tahap optimisasi, yaitu optimisasi desain double bottom dan optimisasi struktur double bottom kapal tanker. Proses optimisasi dilakukan dengan menggunakan software desain Maxsurf dan bahasa pemrograman Visual Basic for Application. Volume ruang muat kapal tanker dengan ukuran 30,000 DWT berhasil dioptimisasi sehingga bertambah sebesar 430.7113 m³ atau 0.99% dari volume ruang muat existing dengan mengoptimalkan desain double bottom. Desain kapal tanker yang baru dapat dihasilkan dengan panjang yang lebih pendek 1.16 m dengan payload hampir sama dengan kondisi existing. Pengurangan panjang ini dapat mengurangi besar beban yang dialami oleh kapal sehingga ukuran komponen struktur pada kapal dapat diminimalkan. Pada akhirnya, diperoleh keuntungan dari berkurangnya berat lightweight (LWT) kapal sebesar 192.1684 ton atau 3.26%.

Oil tankers play an important role in the world economy as the main means of transportation to transport the world's most widely used energy source, oil. Tankers with a size of more than 5,000 DWT are required to be equipped with a double bottom structure based on MARPOL 73/78 and the Common Structural Rules. This structure significantly reduces the volume of cargo oil tank and also increases the weight of the ship's structure. Therefore, research is needed to optimize the design of double bottoms on tankers to maximize the volume of cargo oil tank and minimize the weight of the ship's structure. Various optimization methods can be used to find the most optimal solution, one of which is brute force search method. This research will be carried out in two optimization stages, namely double bottom design optimization and double bottom structure optimization. Optimization process is carried out using Maxsurf design software and Visual Basic for Application programming language. The cargo oil tank volume of a 30,000 DWT tanker was successfully optimized, resulting in an increase of 430.7113 m³, or 0.99% compared to the existing cargo oil tank volume, through the optimization of the double-bottom design. The optimized tanker design achieved a 1.16 m reduction in overall length while maintaining nearly the same payload as the existing vessel. This reduction in length decreases the structural loads acting on the ship, allowing the dimensions of the structural members to be minimized. Consequently, the vessel's lightweight (LWT) was reduced by 192.1684 tonnes, representing a 3.26% decrease.
