TANK FOR LIQUEFIED GAS FOR VESSELS, AND LIQUIFIED GAS CARRYING VESSEL PROVIDED WITH SAME

摘要

This tank for liquefied gas for vessels is a pressure vessel that is symmetrical about the vertical central axis, and includes: an upper tank body that has a lower end opening downward; and a lower tank body that has an upper end opening upward. The vertical sectional shape of one of the upper tank body and the lower tank body passing through the central axis matches a locus represented by the following formula (1): |x/r1|m + |y/r2|m = 1 (1), where: r1 is the radius of the upper end or lower end of the one tank body; r2 is the height of the one tank body; and m is a constant satisfying 2
