Embodiment
[0036] Taking a 310,000-dwt VLCC with an overall length of about 333m, a molded width of 60m, and a molded depth of 30m as an example, a set of optimal design parameters for the cargo tank structure arrangement of a VLCC without swash bulkheads is introduced.
[0037] 1. Subdivision of VLCC cargo tanks without swash bulkheads. like figure 2 As shown, the cargo tank of a traditional VLCC is divided into five tanks along the longitudinal direction, and the typical tank length is 50.94m. The effective sloshing lengths of the first four side cargo oil tanks from bow to stern are all greater than 0.13 times the structural ship length, and sloshing bulkheads are required. And as Figure 5 As shown, in the subdivision form adopted by the present invention, the lengths of the cargo tanks are different, and the length of the three groups of cargo oil tanks on the shorter side is taken as 43.2m, so that the effective sloshing length is less than 0.13 times the length of the structura...
