| Abstract: | To improve the economy of inert gas replacement on the LPG carriers, the four replacement methods commonly used were analyzed by mathematical models. The calculation results showed that the method of vacuum/nitrogen combination will achieve good economic effect. Before dry-docking repairs of the LPG carrier, adopting the method of vacuum, filling with nitrogen gas and pressurized water combination will achieve the desired economic effect. |
