Abstract

FIELD: shipbuilding. SUBSTANCE: cargo volume of ship having double sides and double bottom is divided longitudinally into compartments by means of transverse bulkheads. One of two adjacent compartments relative to each transverse bulkhead has continuous deck ceiling and other compartment is provided with cargo hatch, thus alternating the tanks and holds longitudinally. Two beams secured on deck longitudinally act as longitudinal coatings for cargo hatches. EFFECT: enhanced reliability. 4 dwg

Description

 The invention relates to shipbuilding, in particular to the design of the hull.

 It is known dry bulk carrier ship Balkanker "Boris Butoma" / cm. Sea Fleet magazine, N 10, 1978 /, containing a double-bottom hull, double sides, transverse bulkheads dividing the hull's cargo volume into compartments, and cargo hatches. When changing the type of cargo transported by this vessel, it is necessary to clean the cargo compartments, which takes time, energy, materials.

 The technical result from the use of the invention is to provide improved operational qualities of a dry cargo vessel.

 This technical result is achieved by the fact that in a dry cargo vessel containing a hull with a double bottom, double sides, transverse bulkheads dividing the cargo volume of the hull into compartments, and cargo hatches, one of the two compartments adjacent to each transverse bulkhead is made with a continuous deck coating and the second is equipped with one of the mentioned cargo hatches, while on the deck along the vessel two beams are fixed, installed with the formation of longitudinal coaming of cargo hatches.

 In FIG. 1 shows a top view of a dry cargo vessel; figure 2 is a section aa in figure 1; figure 3 section BB in figure 1; in FIG. 4, section BB in FIG. one.

 The dry cargo vessel has two holds for bulk cargo 1 and tanks for liquid cargo 2. The cargo volume of the ship’s hull along its length is divided by transverse bulkheads 3. Tanks are limited by a longitudinal bulkhead 4 from the side of the diametrical plane, and the latter is absent in the holds. Cargo hatches are provided with covers 5. The vessel has a double bottom 6 and double sides 7. On the deck of the vessel, two beams 8 are rigidly fixed along the length of the cargo volume, sections of which serve as longitudinal coamings of cargo hatches. Decking above the tanks from above is limited by transverse coamings 9 of cargo hatches and channels 10, which are formed by beams 8 with walls 11. Pipes 12 and other elements belonging to the systems with which the tanks are equipped (cargo system, ventilation, etc.) are led out to the channels.

 The vessel can be used to transport only dry cargo, only liquid cargo, liquid and dry cargo at the same time.

 In the first case, holds are loaded and, in addition, containers, for example, can be received on the deck above the tanks and on the hatch covers.

 In the second case, liquid cargo is accepted only in tanks. If it is necessary to differentiate the vessel, the ballast is poured into a double bottom 6 and double sides 7.

 In the third case, both holds and tanks are loaded.

Claims (1)

 Dry cargo vessel containing a hull with a double bottom, double sides, transverse bulkheads dividing the cargo volume of the hull into compartments, and cargo hatches, characterized in that one of the two compartments adjacent to the transverse bulkhead is made with a solid deck overlap, and the second is equipped with one of the mentioned cargo hatches, while on the deck along the vessel two beams are fixed, installed with the formation of longitudinal coaming of cargo hatches.
