The Calculation of Risk of Hazardous Gaseous Emission of Chemical Tankers Based on Plume Model

Abstract:

To assure the safe transportation of bulk liquid chemicals by tankers at sea, not only it is required internationally that dedicated pressure relieving devices should be installed onboard, but the heights of the pressure reducing valves, the activating pressure are also prescribed numerically, although these are based on experiences gained. Actually, researching the relationship among the wind, including the direction and force, the tanker, including her course and speed, the height of an individual pressure reducing valve is more meaningful to improve the safety of lives and properties at sea. Based on plume model, the relationship above mentioned is researched, and the mathematical relation is also presented in this paper.
