主題：異質水流環境下內河集裝箱船舶脫硫塔投資與油品選擇分析
主要內容：Increasingly stringent government regulations are sets to forbid the emission of ships. Fuel switch and scrubber installation are two of the most prevalent strategies for ships to reduce emissions. Fuel switch brings a higher shipping cost by burning low sulfur fuel oil, while scrubber installation results in a high capital cost by setting up desulfurization facilities and continuing to burning high sulfur fuel oil. This paper theocratically investigates the strategy choice of a ship who providing container shipping service along an inland river with non-identical streamflow velocity. Different from the deep-sea shipping service, the sailing speed is the sum of engine speed and the streamflow velocity. Engine speed determines the fuel consumption and sailing speed determines the round-trip time of a ship. By assuming an endogenous decision of engine speed, we found that the streamflow velocity increases the engine speeds and thus costs of a ship under both strategies. Also, the streamflow velocity increases the incentive of a ship to install a scrubber. Furthermore, the emissions under both strategies are also studied and the emission reductions would be distorted by endogenous engine speeds. Numerical experiments based on the Yangtze River are conducted to illustrate the theocratical conclusions.
