(54) COMPOSITE SHIP FOR THE TRANSPORT OF TOXIC CARGO

one

The invention relates to shipbuilding, in particular to composite vessels for the transport of toxic cargo.

A composite ship for transporting toxic cargo is known, containing a cargo section made with a recess and 5 connected with it by means of a hinge with a horizontal axis, equipped with a drive for moving it, a machine section with a propeller-steering complex 1.

The disadvantage of the known vessel is the low safety of navigation.

The purpose of the invention is to improve the safety of navigation of the vessel.

The goal is achieved by the fact that the cargo section is located behind the aft end of the machine section and contains a catamaran with horizontal clearance of at least 1.5 times the screw diameter of the engine section, while the recess is located at the bow end of the catamaran cargo section, the latter is equipped with jo mounted in its stern end a steering device connected by means of a remote drive with a machine section, and the latter is made with a stern superstructure, in which said hinge with gore is located ontalnoy axis and the drive movement of the hinge.

FIG. 1 shows the proposed vessel, a longitudinal section; in fig. 2 - the same, top view.

Claims (1)

The composite vessel consists of a cargo section 1, for example a catamaran, in the forward recess 2 of which the feed part of the single-hinged machine section 3 is located, with both sections being hingedly interconnected by horizontal semi-axes of the connecting hinge 4 located in the aft superstructure 5 of section 3. On decks 6 of the cargo section 1 and its connecting bridge 7 a layer of thermal protection 8 is laid, and on top of it is the bottom of the hold 9, forming together with the cargo coaming 10 a cargo hold where the toxic cargo is placed 11. The catamaran of the cargo section It is complete with horizontal clearance 12, which is at least 1.5 times the diameter of the propeller of the engine section 13, and is equipped with a steering device 14 connected by remote drive with the engine section having a high wheelhouse 15 with a near-circular view and developed residential area. cabin 16. On a composite vessel, section 3 is located in the recess 2 of the cargo section, formed by the bow tips of the catamaran hulls (the stern recess is not present on this cargo section). The vessel works as follows. Section 3, located in the bow of the composition, is a carrying leg, and therefore, a towing force is transmitted from it through the half axles of hinge 4 to the nose of section 1. Clearance 12, which is at least 1.5 times the diameter of the propeller of the section 13, eliminates the negative effect of the propeller jet on the water resistance to the movement of the catamaran cargo section. The open cargo hold with dangerous cargo is placed on the decks of the catamaran hulls and on its bridge 7, the cargo section is equipped with device 14. With this cargo hold location, both sections 1 hulls, especially in the hard-to-reach bottom area, will be more secure in relation to the destructive effect of the toxic cargo 11, for example, hot sinter, which will further enhance the safety of navigation, as well as speed up and simplify cargo operations due to the easy accessibility of any point of the hold by the coastal transshipment facility. tion. Simplification and repair of the cargo sections, associated with the destruction of its structures with hot sinter, as it will be necessary to replace the simpler and more easily accessible deck structures. . As a result. The proposed assembly of the composite vessel is the veritable volatile toxic and separating substances released by the hot agglomerate, including agglomerate dust, during the course of the composition, refer to the stern of section 1, mine machine section 3, where the entire composition of the composition, as well as expensive common propulsive and navigation equipment. On the stand, the insulation of the equipment from the toxic load 11 (including its thermal radiation) is provided by the add-on 5 of the machine section and a considerable distance between the nose coaming 10 and the cabin 16. From the cabin 15 a practically circular view opens. In the event of an accident, section 1 section 3 within a few minutes draws in the half axles of the hinge 4 and disconnects from section 1. The proposed composite vessel ensures the prevention of the harmful effects of toxic secretions of dangerous open cargoes on the crew, i.e., maintaining the health of the seamen; increasing the safety of transporting dangerous goods by special vessels when sailing systematically on busy shipping routes and frequent maneuvering in approach channels and in the port waters, i.e., reducing the possibility of emergency collisions of ships, stranded, etc., due to a significant improvement in visibility from the wheelhouse located in the bow of the composition, as well as the possibility of separation of the sections of the composition in an emergency. The maneuverability of the composite vessel due to communication by means of a remote drive (in Figs. 1 and 2 is shown by a dashed line) of the machine section 3 with the device 14 of the cargo section is improved. Claims of the invention A composite ship for transporting a toxic cargo, comprising a cargo section made with a recess and connected to it by means of a hinge with a horizontal axis, equipped with a drive for its movement, a machine section with a propeller-steering complex, characterized in that , cargo section is located behind the aft end of the machine section and contains a catamaran with a horizontal clearance of at least 1.5 times the screw diameter of the machine section, while the recess is located in the axial extremity of the catamaran cargo section, the latter equipped with a steering device mounted in its aft tip connected by means of a remote drive to the machine section, and the latter made with a feed superstructure, in which the said hinge with a horizontal axis and the hinge displacement drive are located.
