| Abstract: | An economy analysis of a ship form with its block coefficient equal to 0.9 is presented. The design ideas of the economy analysis program for a ship with high block coefficient and some mathematical models such as that for estimating the light weight of a ship and the shipbuilding cost, for the type depth as well as for predicting the ship speed are given. With the main dimensions and main engine power of the ship unchanged, economy comparisons between a ship with high block coefficient and a 20 000 dwt bulk carrier, a 35000 dwt shallow-draft coal carrier have been carried out and sensitivity analysis made. Calculation results show that the economy of ships with high block coefficient is fairly good. |
