CARGO HOLD STRUCTURE FOR A CRUDE OIL CARRIER

摘要

The aim of the present invention is to provide a cargo hold structure for a crude oil carrier that enables sloshing loads to be controlled without installing crossties, and that can retain the structural strength thereof at a suitably designed level by means of increasing the width of a plurality of vertical webs installed along the height of a ship hull with respect to a longitudinal bulkhead of the cargo hold, and interconnecting and supporting the plurality of vertical webs by means of horizontal girders provided therebetween. To achieve the above aim, a cargo hold structure for a crude oil carrier according to the present invention comprises: a longitudinal bulkhead (20) disposed longitudinally along a ship hull; and a plurality of vertical webs (22) coupled along the height of the ship hull with respect to the longitudinal bulkhead (20). The vertical webs (22) have a width that is 0.15 to 0.20 times the overall height (H) of the cargo hold, a horizontal girder (24) is connected longitudinally between the vertical webs (22) along a ship hull, and the horizontal girder (24) is disposed within a range of 30% to 60% of the overall height (H) of the cargo hold from the bottom of the cargo hold.
