The invention relates to a rescue technique, namely, devices for lifting from the water surface floating objects, such as landers.A device for lifting the floating object containing a capture made with the body, and connecting elements to interact with the response element gripper mounted on a floating object.A disadvantage of this device is the complexity of its design.The purpose of the invention is to simplify the design.E is m, and connecting elements to interact with the response element capture, set on a floating object, the body of the grip is made with the load bearing beams, interconnected one of their ends and arranged in one plane at an angle of 120 5aboutone to another, and also with lifting eye mounted on the supporting beams at their point of connection. Each carrier beam made with arc vertical slot, in which is movably mounted a corresponding connecting element can be locked in one of the made in response to the capture element, designed as a circular power belts.Each of the supporting beams can be performed with the tide on its bottom side in the form of a sector whose radius is less than half the internal diameter of the power belt.In Fig.1 presents a General view of the device attached to the object; Fig.2 - the same, top view.The device consists of a casing gripper is made of load-bearing beams 1, interconnected by one of their ends to a common base 2 and arranged in the same plane at an angle of 120 5oone to another, a winding ring 3 mounted on the supporting beams at their point of connection. The beams have arc vertical slot 4. Holes 5, the city is the quiet, in turn, are able to move in the slots 4, providing the convenience of attaching the device to the object, as it does not require precise installation on the object. On the lower side of each of the carrier beams made tide 9 in the form of a sector whose radius is less than half the internal diameter of the power belt 6. When installing the unit on the object tides are included in the recess formed by the power zone and the upper part of the object that provides the ease of installation and fixation device from movement in the plane of the power belt) at object.The beams are connected by a ring 10, which provides ease of rotation around the axis when the alignment of the connecting elements of the device and holes in the security zone.The invention is carried out as follows.The ring 3 is attached to the hook lifting devices of the vessel. The device is induced to the floating object 6 so that one of the connecting elements 8 fell into the hole 5 of the power belt 6. Holding device for the ring 10, the rescuer brings other connecting elements on hole 5. At the entrance of the connecting elements into the holes tides 9 is fixed in the recess of the object and fix the device on the power belt 6 from the horizontal displacements. Quarter the and the ring 3, the object is lifted on Board the vessel and secured in a special setup. Connecting elements are in the original position and the device is removed from the object.This design provides improved performance of the device by reducing the number of operations performed by the rescuer in the preparation of the device and retaining it on a raised object and decrease the distance from the hook lifting devices of the vessel to raise the object about 3 meters, which greatly expands the number of ships that can solve the problem of lifting an object on the Board. 1. The DEVICE FOR LIFTING the FLOATING OBJECT containing a capture made with the body, and connecting elements to interact with the response element gripper mounted on a floating object, characterized in that the body of the grip is made with the load bearing beams, interconnected among their ends and arranged in one plane at an angle of 120 5oone to another, and also with lifting eye mounted on the supporting beams at their point of connection with each carrier beam made with arc vertical slot, in which is movably mounted a corresponding connecting element as possible is made in the form of an annular power belts.2. The device under item 1, characterized in that each carrier beam made with the tide on its bottom side in the form of a sector whose radius is less than half the internal diameter of the power zone.
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.

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.

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.
