| 摘要 | The present invention relates to a method of manufacturing a tank which is too large to be built on the ground. In the method, a floating station (1012) is built on the sea, surrounding a first spherical shell section (1002a) which constitutes one end of the tank. In the floating station, a hollow cylindrical section is built in a vertical position, connected to the first spherical shell section. The second spherical shell section (1002b) constituting the other end of the tank is connected to the open end of the hollow cylindrical section. | ||||||
| 权利要求 | What is claimed is:1. A method of manufacturing a large tank comprising the steps of:constructing a floating base on the sea around a first spherical shell section constituting one end of a tank;building a hollow cylindrical section on the spherical shell section, in the floating base;attaching a first open end of the cylindrical section to the first spherical shell section; andattaching a second spherical shell section to a second open end of the hollow cylindrical section to close the second open end thereof. |
