The method of loading and unloading ships move oversized cargo in the hold and back
(57) Abstract:The invention relates to shipbuilding and marine transport and concerning the technology of transportation ' ice-blocks and vessels with their cargoes. The method is that the use of ship-ship, have it in the dock, regulate the level of water in it, place the vessel on the keel-blocks opposite the pier specialized berth, sostakovic pierce transit compartment of the vessel and move the cargo from the dock to the ship and back. Pier and referred to the pier can be in the form of design located therein with a groove cross-section whose shape and size corresponds to the cross section of the hold of the ship. Pier can be made with the possibility of moving in the vertical and horizontal planes. The technical result of the invention is to optimize the process of loading and unloading the vessel, loaded with multi-thousand tons, solid cargoes through single move them into the holds through the special design of the bow or stern. 2 C.p. f-crystals, 2 Il. The invention relates to shipbuilding, and specifically to the design of the ships and their cargo holds intended for the carriage of timber l directly handling of water in the hold and back (patent RU 2144883), namely, that the movement of goods (bars ice, barcons) through the receiving and transit compartments of the vessel by regulating the water level in them. This method is carried out by trimarans-Ledovoye (patent RU 2145290 and EN 2145562).The disadvantage of the above method is the necessity of repeated intake and discharge of water in the receiving and transit compartments when performing loading and unloading operations.As transportation barcons is carried out between the ports, you can achieve the loading-unloading in ports, using coastal infrastructure. Unloading of bars ice also occurs in the ports where you can use various means and ways to optimize this process.The aim of the present invention is the optimization process of the loading-unloading vessel, loaded with multi-thousand tons, solid cargoes single move them directly into the hold through the special design of the bow or the stern.This goal is achieved by the use of ship-ship, have it in the dock, regulate the level of water in it, place the vessel on the keel-blocks of naproti the Ala into the hold of the ship and back. Pearce and special berth made in the form of design located therein with a groove cross-section whose shape and size corresponds to the cross section of the hold of the ship. Pier specialized berth is made with the possibility of moving in the vertical and horizontal planes.The process of loading and unloading is considered on the example of the transport ship - ship (patent RU 2145562), ship-N (RU patent 2145290) and barkana (patent RU 2149122). To avoid the disadvantages of the method of handling described in patent RU 2144883, it is proposed the following method of handling.In Fig. 1 shows the layout of the ship-ship (medium case) in the dock to the operations of loading and unloading.In Fig. 2 is a diagram of the loading and unloading of the ship-ship (average case).Loading-unloading vessel barcons and unloading of bars ice occurs in the dock. Ship-ship 1, entering the dock, opens bilge gate 2, thereby opening up the compartment 5, and runs over to pier 8 specialized berth 7, placing pier 8 in the receiving compartment 5 of the vessel, and is located in a prescribed position above the keel-blocks 10. The water level lowers and place the vessel on Kiri this position of the vessel transit compartment 5 of the hold will be on the same level with the pier 8 and dock with him, allowing the opening of the partitions 3 and 4, the hold of the ship to carry out loading and unloading operations. Design a specialized berth 7 can be performed with the possibility of height adjustment. Pier 8 can be made retractable. Special berth 7 is placed at one side of the dock and made with the possibility of adopting a multi-thousand tons ' ice-blocks (barcons) 11. Pier 8 specialized berth 7 protrudes into the interior of the waters of the dock and is a structure with located therein with a groove cross-section whose shape and size corresponds to the cross section of the hold of the ship 1, and its length allows the handling of ' ice-blocks (barcons) 11 for the purpose. In a specialized berth 7 is a bulkhead 9 to eliminate water damage inside of a specialized berth before docking with the ship 1. 1. The method of loading and unloading ships moving oversize loads directly into the hold and back, characterized in that the use of ship-ship, have it in the dock, regulate the level of water in it, place the vessel on the keel-blocks opposite the pier specialized berth, sostakovic PI is trichosis fact, what Pearce and special berth made in the form of design located therein with a groove cross-section whose shape and size corresponds to the cross section of the hold of the ship.3. The method according to p. 1, characterized in that the pier specialized berth is made with the possibility of moving in the vertical and horizontal planes.
SUBSTANCE: two-hull object surfacing is performed by force of pulling-and-running device (PRD) which force is adequate to waterless mass of object in external hull, for which purpose hoisting winches are actuated for lifting irrespective of wave phase, and follower winches of load cable are set to braking, which causes water drain from external hull beyond the board until the object is lifted from surface. Constant tension of load cable during sequential oscillations is maintained by damper operation. Invention covers also the device for this method implementation.
EFFECT: improved PRD operational performance, possibility to lower its mass and dimensions.

FIELD: rescue equipment.
SUBSTANCE: method of providing crew evacuation of emergency submarine from emersed saving chamber (ESC) is that the crew evacuation is based on using the launching device of a rescue ship and a ship's ladder. The ESC of vertical design is provided with lifting rods and fencing of the exit hatch. The launching device of the rescue ship is provided with a traverse with the variable base between the automatic grips, through which the ESC is raised from water to the height excluding the relative heaving oscillations of the ESC and the rescue ship, and fixed at the fendering protection against longitudinal movement with mooring-towing ropes. The ship's ladder is brought to the fencing of the exit hatch of the ESC and the rescued are evacuated on the ship's ladder to the board of the rescue ship.
EFFECT: increased safety of the crew evacuation from the emersed saving chamber to the rescue ship under conditions of sea waves.
SUBSTANCE: rescue means boarding device comprises the slip arranged at the vessel aft, towing winch with towing rope, rescue craft catch assembly and drone with remote control. Cargo winch and remote control assembly are mounted at the drone airframe. Rescue craft catch assembly is composed of the screen-and scoop-like span with elastic resilient thrust ring at the lower part. Tightening rope at said thrust ring is connected with the cargo winch towing rope running end. The drone remote control assembly is connected with the drone controls via radio channel and composed of the drone flight ACS and GPS or GLONASS radio navigation complex.
EFFECT: higher safety.

SUBSTANCE: trimaran type ship with outriggers-energy modules, consisting of the main body, two lateral buoyancy - outriggers and underwater bridges connecting them with the body is proposed. The whole energy plant of the ship is taken out of the hull into outriggers and bridges. This provides the formation of an extended tunnel in the hull, adapted for entering a floating craft into it through a cutout in the hull transom.
EFFECT: basing of relatively large floating crafts on a relatively small vessel without lifting them on the ship and without a bulky lifting device.
