Cargo hold structure for a very large crude oil carrier

摘要

A cargo hold structure for an oil tanker is provided, in which a plurality of vertical webs that is mounted on longitudinal bulkheads of the cargo hold in a height direction of a hull is made wide and horizontal girders which connect the vertical webs to each other and support them, thereby controlling the sloshing load of the cargo hold and improving the structural strength of the cargo hold without having to mount crossties. The cargo hold structure includes a longitudinal bulkhead (20) arranged in a lengthwise direction of a hull to divide an internal space, a plurality of vertical webs (22) coupled onto the longitudinal bulkhead (20) in a height direction of the hull, the vertical web (22) having a width of 0.15 to 0.20 times the total height (H) of the cargo hold, and a horizontal girder (24) arranged between the vertical webs (22) in the lengthwise direction of the hull, the level of the horizontal girder (24) being within 30% to 60% of the total height (H) of the cargo hold from the bottom thereof.
