Abstrak :
Angkatan laut adalah komponen militer yang paling penting, yang secara substansial untuk sebuah negara yang terdiri dari laut, bersama dengan sebuah bangsa yang dimaksudkan untuk menyeberang laut. Dengan demikian, kapal perang angkatan laut adalah suatu keharusan; Mereka adalah kekuatan tempur dan pencegahan utama terhadap kemungkinan agresi. Kapal perang angkatan laut memiliki banyak kapal militer yang memiliki teknologi mutakhir dalam desain dan rekayasa. Alternatif untuk kapal permukaan berkecepatan tinggi yang sering diaplikasikan adalah kapal multihull. Pada zona kecepatan tinggi, multihull menawarkan beberapa kelebihan dibandingkan kapal monohull konvensional seperti: stabilitas dan pengurangan drag pembuatan gelombang optimal pada kecepatan tertentu. Dengan demikian, pendekatan desain multihull adalah banyak alternatif yang dapat diandalkan di antara desain lambung alternatif lainnya, terutama pada wilayah kecepatan perang yang tinggi. Kajian ini dilakukan dalam dua bab. Bab pertama menjelaskan kapal perang angkatan laut. Pada kajian selanjutnya, multihull digambarkan dengan aspek aliran dan hambatan. Tinjauan ini masih terkait dengan topik di atas. Satu-satunya aspek ketahanan multihull yang tercakup dalam tesis ini adalah hambatan pembuatan gelombang karena merupakan komponen utama dari hambatan total. Penelitian tentang topik ini telah dijelaskan dan kesimpulannya diberikan. Rekomendasi juga diberikan di akhir tesis. Makalah penulis disajikan sebagai lampiran.

Navy is the most consequential of military component, substantially for a nation comprised by sea, along with a nation intended to set upon across sea. Thus, naval warships are a must they are the strikebreaking force and main deterrence against possible aggression. Naval warships contain many military vessels possessed with cutting edge technology of ship design and engineering. An alternative for a high speed surface vessel which had often been applied is a multihull ship. On high speed regime, multihull offers some advantages over the conventional monohull vessel such as stability, small draught operation, and optimum wave making drag reduction at some speed. Accordingly, a multihull design approach are a great deal of reliable alternative among any other alternative hull design, especially on the high speed region of war purpose.The review is conducted in two chapters. The first chapter describes naval warships in a brief. On the next review, multihull is described by fluid flow and resistance aspects. This review still associates with the foregoing topic. The only resistance aspect of multihull that is covered in this thesis is the wave making resistance because it is the major component of multihull total resistance. Research on this topic has been described and the conclusion is given. A recommendation is also given in the end of the thesis. The author papers are presented as appendixes.

Ship optimization design is critical to the preliminary design of a ship. With the rapid development of computer technology, the simulation-based design (SBD) technique has been introduced into the field of ship design. Typical SBD consists of three parts: geometric reconstruction; CFD numerical simulation; and optimization. In the context of ship design, these are used to alter the shape of the ship, evaluate the objective function and to assess the hull form space respectively. As such, the SBD technique opens up new opportunities and paves the way for a new method for optimal ship design. This book discusses the problem of optimizing ship’s hulls, highlighting the key technologies of ship optimization design and presenting a series of hull-form optimization platforms. It includes several improved approaches and novel ideas with significant potential in this field
