Abstract

A cargo hold having a plurality of spaces, which are formed by a longitudinal bulkhead and a transverse bulkhead intersecting each other and store crude oil, comprises a void space located at least one corner among corners formed by intersection of the longitudinal bulkhead and the transverse bulkhead, wherein the void space is formed of a void space structure having one side end and the other side end sealed by and fixed to the longitudinal bulkhead and the transverse bulkhead, respectively, thereby forming an empty space inside the bulkheads. The vessel cargo hold prevents a danger, such as fire and explosion, which may occur during the maintenance or repair of the vessel cargo hold for storing crude oil, and decreases work or the like required for the maintenance or repair of the cargo hold.

First claim

What is claimed is:

1. A vessel cargo hold having a plurality of spaces, which are formed by a longitudinal bulkhead and a transverse bulkhead intersecting each other, the vessel cargo hold comprising a void space located in at least one corner of corners formed by an intersection of the longitudinal bulkhead and the transverse bulkhead, wherein the void space has a square tubular shape formed by a void space structure having two rectangular and perpendicular side panels, a first side end and a second side end of the void space structure being sealed by and fixed to the longitudinal bulkhead and the transverse bulkhead, respectively, the void space structure further having bottom and top ends sealed by and fixed to, respectively, a bottom deck and a top deck of the vessel cargo hold, the void space structure thereby wrapping and surrounding the at least one corner of corners at the intersection and sealing the void space horizontally between the first and second side ends and the at least one corner of corners at the intersection, and sealing the void space vertically between the top deck and bottom deck, to prevent fluid stored in the cargo hold from flowing into the void space,
wherein the void spaces structures are mounted to each side of the longitudinal bulkhead or the transverse bulkhead, and further comprising a passage formed in the longitudinal bulkhead or the transverse bulkhead between the void spaces on each side of the longitudinal bulkhead or the transverse bulkhead.

2. The vessel cargo hold according to claim 1 , wherein the void space structure is fixed to one or two corners among four corners of the space formed by intersection of the longitudinal bulkhead and the transverse bulkhead.

3. The vessel cargo hold according to claim 2 , wherein the first side end of void space structure is welded in contact with the transverse bulkhead, and the second side end of the void space structure is welded in contact with the longitudinal bulkhead.
