Principal Dimensions and Coefficient Selection and Ship Lines Design for New Ocean Salvage Vessel

According to the special missions and demands for the sea salvage, the principal dimensions and coefficients, lines design feature of the ocean salvage ship are analysed and researched on. The ship form features are indroduced. The range of the principal dimensions and coefficients are provided. Moreover, the analysis on the ship mode test results are carried out for different bow form, propulsion type and with or without anti rolling fin, and the results have been rerified by sea trials. The path and basis for improving navigation performances of the salvage ship are indicated.
