SHIP RESISTANCE AND PROPULSION

From ship resistance, we can figure out how much power required for Main Engine at a specified speed and what type of propeller should be used.

1st Step: Resistance calculation at a range of operation speed ( Base on Hull basic information, coefficient, proper method)

Base on type of method, The power could be Horse power (HP) or Kg, The speed could be knots/h

2nd Step: Initial TOWING power requires for propeller ( base on the Step 1 Resistance, hull form, fluid form, required speed, water density, coefficient ect., )

3rd Step: Choose Type of Propeller and generate the Initial Characteristic chart ( with Power, RPM, propeller Diameter )

4th step: Choose M.E with relevant RPM, Power & proper Diameter of a propeller.

Final step: Re-analysis the detail final characteristic of the propeller at specified RPM.
