Abstract

Pola gelombang yang ditimbulkan oleh lambung kapal yang melaju sangat penting ketika mempertimbangkan kualitas desain lambung dan prediksi hambatan. Makalah ini membahas kajian pola gelombang sekitar monohull (demihull) dan lambung ganda (catamaran) dengan jarak lambung bervariasi. Estimasi numerik hambatan dan interaksi gelombang kapal yang dihasilkan dilakukan dengan menerapkan teknik-teknik numerik untuk menghitung pola gelombang timbul dan hambatannya, dengan permukaan air tenang. Hasil perhitungan numerik untuk kedua demihull dan catamaran dibandingkan dan dibahas secara rinci.Keywords : Twin hull, Wave pattern, Resistance, Simulation

Abstract

Makalah ini membahas pengujian hambatan model kapal Surface Effect Planning Hull (SEP-Hull). Model uji menggunakan sistem pelumasan udara di bawah permukaan lambung kapal untuk mengetahui pengaruh sistem pelumasan terhadap gaya hambatan kapal. Model ini terbuat dari bahan fiberglass dan diuji pada kecepatan, Fn 0.1-1.45, di towing tank- UPT Balai Pengkajian dan Penelitian Hidrodinamika BPPT, Surabaya. Gaya hambatan model kapal diukur dengan alat ukur ‘load cell transducer’. Hasil pengujian model dipresentasikan dalam bentuk grafik dan tabel. Dari hasil uji diperoleh bahwa hambatan total kapal berkurang hingga 30 persen dengan mengaplikasikan sistim pelumasan udara di bawah permukaan lambung kapal. Hasil ini memberikan harapan yang menjanjikan dalam dunia perkapalan.

Abstract

The past decade has witnessed a rapid growth of interest in the development of fast catamaran for various applications. The paper describes the study of interference resistance components on demihull separation. Catamarans or twin-hull vessels may be formed either by connecting two symmetrical demihulls or by splitting a mono hull into two halves to form two asymmetric demihulls. The slender body method in HullSpeed- Maxsurf Program was used for predicting the resistance components. The method assumes that the ship’s beam is small compared to its length. Effect of resistance interference components on catamaran hull separations are explained and discussed with some work from other published data, which shows good agreement.

Abstract

The increase of fuel price has caused fleet operational and shipping business to be in danger situation. The fuel consumption of a ship is influenced by ship volume or wetted area which contributes directly to the increase of ship resistance and the size of main engine. In order to find out the appropriate answers, a series of investigation into river transportation using monohull, catamaran and trimaran types of vessel was carried out. The work focused on the estimation of total resistance and powering as well as seakeeping characteristics and carried out experimentally using tank test and numerically using a ship design software (Maxsurf). It was found out that the catamaran and trimaran could have less resistance and hence power compared to monohull of similar displacement. The seakeeping characteristics of the multihull vessels were also comparable with those of the monohull. This is a good indication that river catamaran/trimaran is an efficient and comfortable vessel. If a prototype or real vessel is developed, it can be a very efficient ship as well as a ship with high safety standard.
