- Abstract
Economic speed of a ship is a fixed value in existing studies, but it is changing. The ship's functional coefficient formula is imported into the economic speed expression to study the actual variability of the ship’s economic speed, and get 5 main influencing factors. Taking a typical ship type as an example, first the dynamics of the economic speed and its changing trend under the single-factor variation are analyzed by two-dimensional curve. The fluctuation range of economic speed caused by the variation range of fuel consumption rate is relatively obvious. Economic speed has a convex decreasing status on displacement, fuel consumption and oil price, and a concave increasing status on daily fixed cost and average profit. The impact of displacement on economic speed should be paid attention on ocean shipping routes and ships with low cargo load, and the economic speed fluctuates relatively large when the everyday fixed cost and profit are low. After that, the dynamics and trend of the economic speed under the two-factor variation are analyzed by three-dimensional surface, and the impacts of distance, shipping market, age, cargo capacity, business model, maintenance level, fiscal and tax policies on economic speed can be obtained.
