The method of loading and unloading on the trimaran under water cargo moving them directly from the water into the hold and back
(57) Abstract:The invention relates to shipbuilding and relates to a method of loading and unloading on the trimaran under water cargo moving them directly from the water into the hold and back. The method consists in the fact that the ship is a trimaran fitted over the cargo opening is made in the bottom of the middle hull of the leaf. Take the pop-up cargo. After that close the sash bottom, pumping sea water and place the cargo in the hold. Allows loading and unloading of large, multi-thousand tons of cargo under water. 5 Il. As is known, the loading and unloading of the majority of vessels of different kind of goods in ports by using shore crane, pump, etc. equipment. The current level of development of loading and unloading equipment can lift and carry in boat loads weighing several tens of tons. Themselves of the court, except for special, do not have equipment to conduct loading and unloading operations due to unnecessary because are loaded and unloaded in ports.There are such court, as the ferry landing, which are loaded from the shore ramps through the nose or to the et ships, designed to handle one-time receptions large and multi-thousand tons of cargo. Because to move such cargo on a vessel required loading equipment, which in the foreseeable future will not be made, and the need for transportation of such goods is overdue, it is proposed a method of handling operations consisting in the movement of cargo from the water directly into the hold, using a special design of the ship.The aim of the study is to develop a method of loading and unloading of large, multi-thousand tons, one-piece cargo under water (at the bottom), moving it directly from the water into the hold through the special design of the bottom of the middle hull.The need to develop transport vessels for loading and unloading and transportation of multi-thousand tons of solid goods arose from the need to reduce the time required for loading and unloading operations.This goal is achieved by the use of ship-trimaran, average housing which has a bottom disclose shutters, boat trimaran fitted over the load, the opening of the bottom, take the pop-up load, then close shutters on the th vessel-trimaran.The figure 2 shows a diagram of the middle hull of the trimaran with deployable wings of the bottom.In figures 3-5 shows the loading of the trimaran.Structurally, the ship is a trimaran, because this design provides the greatest stability, buoyancy and a margin of safety during loading and unloading and transportation. Location of ship engines, in addition to the average case, in the side casings of the auxiliary, as in conventional trimaran, turned into the equivalent of a major, gave the high maneuverability of the trimaran required for loading and unloading of bulky goods, being in water.Consider the transport ship is a trimaran. The vessel 1 consists of three buildings (Fig. 1): average (cargo) case 2 and the side wings 3. All buildings are equipped with ship power plants (with propellers 4). The average hull 2 of the vessel is a cargo. Housings are fastened together micorphone bracket 5. On deck 6 is the add-on 7 and on the sides of buildings - add-8. The bottom of the middle hull consists of a drop-down shutters 9 (shutters closed) and 10 (sash disclosed).Look at the USA trimaran. Is printablepage secondary hull to the calculated values, providing for the receiving of cargo directly from the water into the hold through the open shutters of the bottom. Average trimaran hull takes pop up the load 12. Next, close the sash bottom. Outboard water remaining in the hold, is pumped overboard and the load is placed in the hold. Vessel is ready for shipment and should be in the port of destination.The vessel is equipped with a variety of crane equipment, which can be used for lifting loads, objects from the bottom.The design and dimensions of all three hulls of the trimaran provide and provide the necessary buoyancy of the vessel during loading and unloading operations from beginning to end.The surgery ship unloading is the reverse of loading operations.In case of rejection of the cargo weight in the average case from the settlement (within tolerance) provides the ability to adjust the settling of the side hulls of the vessel through the fence (emission) of sea water in the side of the building to relieve stresses arising in micorphone mounts).Great value in this vessel will have a design mikaboshi kreplenijah operations, and during transportation, damping the displacement of the housings relative to each other with side rolling, which should be provided by the possibility of their moving in vertical and horizontal planes. Along with micorphone fastenings 5, between buildings 2 and 3 may use different mikaboshi deck structures 11, working on bending and compression.Angle mikaboshi fasteners 5 (Fig. 1) will be selected in such a way as to reduce the voltage in the construction mikaboshi fasteners when the sailing vessel and the optimal way to combine a force marine engines of the side housings 3 with the direction of the axis of movement of the middle housing 2. The method of loading and unloading on the trimaran under water cargo moving them directly from the water into the hold and back, characterized in that the ship is a trimaran fitted over the cargo opening is made in the bottom of the middle hull of the leaf, take the pop-up load, then close the sash bottom, pumping sea water and place the cargo in the hold.
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.

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.
