Comparison and analysis on ship types of small and medium size trailing suction hopper dredger

Abstract

In order to study ship type of small and medium size tailing suction hopper dredger (TSHD), a comparative analysis targeted to Pallieter and Hangjun4009 is carried out. By comparing main dimensions, hull lines and principal characteristics, the usability of TSHD with a bigger block coefficient and a bigger width/draught ratio is studied. Based on calculation of wave-making resistance coefficients, the effect of special bulbous bow on wave-making resistance is studied.
