Abstract:
1. A method for analyzing voyage efficiency, the method comprising: creating an initial model of a ship, the initial model configured to perform simulations and generate voyage solutions for the ship on an ocean, the initial model incorporating detailed ship-specific data; obtaining historical data for a completed voyage of the ship on the ocean, historical data including at least weather and ocean information; simulating the previously completed voyage for the ship using the initial model to form a simulated voyage; comparing performance data for the previously completed voyage to performance data for the simulated voyage to identify a correlation coefficient comprising at least a propeller wake factor; changing the initial model using the correlation coefficient to generate a changed initial model; generating a baseline voyage solution by a processor for the completed voyage with a software application executing on a processor unit using the changed initial model of the ship and the historical data; generating an actual voyage solution for the ship; identifying a first number of parameters generated for the baseline voyage solution; identifying a second number of parameters generated for the actual voyage solution used for the completed voyage; comparing on the processor the first number of parameters to the second number of parameters to form a comparison, including comparing each segment in a plurality of segments in the baseline voyage solution for the completed voyage to a corresponding segment in a plurality of segments in the actual voyage solution used for the completed voyage to form the comparison in order to determine the voyage efficiency, the comparing identifying a correlation coefficient between the baseline voyage solution and the actual voyage solution comprising a propeller wake factor, and the comparing including identifying a difference between the first number of parameters the second number of parameters to form the comparison expressed as a percentage; adjusting the changed initial model with the correlation coefficient to match an actual recorded ship performance, including fuel efficiency, speed, and probability of arriving on time at the destination, to form an adjusted model; and generating a new voyage solution based on the comparison and the adjusted model.
