| description | Resistance or drag is one
of the most important factors in ship design, in particular in connection with
the development of more efficient and environmentally friendly vessels. The
shape of the hull under water will affect the fluid flow characteristics around
the ship, hence causing the resistance to increase or decrease. If the
resistance increases, the size of main engine and subsequently, the fuel
consumption increases accordingly and this is not often anticipated by ship
designers and operators. The use of a catamaran for passenger carriers is well
known and its application for fishing vessels has received serious attention in
the last few years, due to its advantages to produce wider deck area and
smaller size of engine at the same displacement as the monohulls. The
conversion of monohull fishing vessels in Cilacap the waters into a catamaran
hull is an interesting topic in association with the development of better
fishing vessels in this region. The resistance investigation of the conversion
vessel was carried out by Computational Fluid Dynamics (CFD) approach and this
is combined with classical slender body theory. In terms of mathematical
calculation, the results between CFD and the combination of empirical formulas
and slender body theory shows such a good agreement and the difference between
the two is less than 5%. In terms of naval architecture, the results showed
that the modification of a monohull vessel into a catamaran can increase the
payload capacity up to two times. Conversely, this causes the resistance to
increase about almost four times and this is certainly unpopular for the
fishermen. |
