Description

(54) HULL SHIP

one

This invention relates to shipbuilding, in particular to ship hulls.

The ship's hull is known to contain several intermediate and impermeable upper decks, transverse watertight bulkheads, brought to the upper impermeable decks and form, together with the intermediate decks and sides, double deck areas, double sides, brought to one of the intermediate decks located above the emergency waterline 1.

However, the known hull of the vessel does not have sufficient stability.

The purpose of the invention is to increase the emergency stability of the vessel.

The goal is achieved by the fact that in the intermediate decks located above the emergency waterline, cuts are made at the sides, and the lower deck spaces are connected to the atmosphere by means of air ducts.

In addition, overflow pipes are installed in the double sides of the vessel, connecting the inter-deck rooms.

FIG. 1 shows the cargo compartment of the vessel, a longitudinal section; in fig. 2 - section

A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one.

The hull of the vessel contains several intermediate decks 2 and transverse watertight bulkheads 3, bounding the cargo compartment, and they are brought to the upper impermeable deck 4. The transverse bulkheads 3 and intermediate decks 2 form mezzanine spaces 5. Double sides 6 are brought to one of the intermediate decks located

10 above the emergency waterline, in which notches 7 are made at the sides of the hull 1, and the lower deck spaces 5 are connected to the atmosphere by air ducts 8. Between the double sides

15 6, overflow pipes 9 are installed connecting inter-deck spaces.

In the case of holes in the vessel's side, transverse bulkheads 3 prevent the spread of water outside the compartment, and the air ducts 8 prevent the formation of airbags in the lower volumes of the flooded compartment. When sailing with emergency waterline A, the notches 7 in the deck provide water bypass through the hole into the lower volume, and when sailing from the emergency waterline B, water passes through the notches 7 and bypass pipes 9 if double decks 6 are brought to one of the decks.

The presence of cuts in the main cargo deck at the side of the ship and bringing the bulkheads bounding the compartment to the upper deck reduces the likelihood of loss of stability of the ship in the event of a hole in the board and, therefore, helps to prevent the death of the ship.
