Description

The invention relates to methods for protecting sea vessels from attack and capture by pirates.

There is a known method of protection against terrorists in water basins (RF patent for invention No. 2551604, IPC F41H 9/04, B63G 13/00, publ. 05/27/2015), which consists in the fact that a non-lethal means of destruction based on an irritant, for example CS, is established on a ship in a complex of weapons with unmanned aerial vehicles (UAVs), both reconnaissance and strike, and also install a system for reconnaissance of a dangerous area in a line of sight with a width of up to ± 15 miles relative to the ship's route along the preliminary laying, and the reconnaissance vehicle is directed directly to an object detected by a ship's radar station when accompanied from a ship's mobile laptop connected to the GLONASS system, and when the ship moves in a narrow area, reconnaissance of the water area is carried out on both sides of the fairway axis to the coastline equipped with observation posts, in case of detection of a dangerous object, perform the following tactics: produce a demonstrative warning An extensive flight of a reconnaissance UAV over an object classified by the operators of the complex together with navigators as safe at the time of detection, carry out a demonstrative and preventive attack by a shock UAV of an object classified as potentially dangerous, with an aerosol cloud.

This method of protection against terrorists in water bodies has several disadvantages. First, for its implementation, a specially trained operator is required, who will perform only this function on the ship, which will lead to an increase in economic costs for the shipowner. Secondly, pirates, using personal protective equipment, can overcome the aerosol cloud, board and hijack the ship and the crew. At the same time, the release of the ship by the military who patrol potentially dangerous areas of the world's oceans will be impossible due to the presence of hostages. Third, pirates in most cases have automatic weapons, which will allow them to shoot down an unmanned aerial vehicle when it is lowered to the lowest possible height to set the curtain.

Known maritime security system (RF patent for invention No. 2514955, IPC B63G 13/00, F41H 9/04, publ. 05/10/2014), which has made with the possibility of fixing on the ship's hull drain for a liquid or gaseous substance supplied by means of at least one pump through pipelines to the overflow with the possibility of its outflow outside the ship's hull to protect against pirate attacks, and at least two different control elements and a control system connected to them, which, depending on the readings of various control elements, initiates an alarm and / or activates signaling devices, wherein the monitoring elements are designed as monitoring devices and / or monitoring sensors, in particular as an optical camera, an infrared camera and / or a radar device, or alternatively as an acoustic sensor, a motion sensor, an optical sensor and / or an infrared sensor.

The disadvantage of this maritime security system is that if pirates overcome these protective devices made in the form of pipelines with a substance flowing out of them, they can take the crew members hostage and send the ship to the port in order to further obtain ransom. At the same time, the presence of hostages will not allow the military, located in this area of the world ocean, to storm the vessel, as this can endanger the life and health of the hostages, and therefore is prohibited by the current instructions.

As the closest analogue, a warning system about the approach of pirate-hazardous targets was adopted, containing an automatic radar plotting device (ARPA), which includes information sensors (navigation radar station, vessel position determination devices (GLONASS / GPS), vessel heading device, vessel speed determination device ), interfacing and switching units (the first voice annunciator designed to record and transmit a message about a pirate attack, the second voice annunciator intended to notify the crew of the need to immediately stop all work and hide in the citadel, an external alarm switch, an interface device), units warning and external signaling (VHF radio station keeping watch on the sixteenth channel, ship loudspeaker communication, ship emergency communication, external loudspeaker connected to ship loudspeaker communication, external loudspeaker connected to ship emergency communication, external lights th siren connected to the ship's emergency communication, the antenna of the ship's VHF radio station) (Timofeev V.K., Sukhoruk A.I., Sergienko I.M. The use of automatic radar plotting devices (ARPA) to improve the safety of fishing vessels in the field in an emergency associated with a pirate attack [Electronic resource] // Baltic Maritime Forum: materials of the VI International Baltic Maritime Forum September 3-6, 2018: In 6 volumes. T. 2. “Marine engineering and technology. Safety of the Marine Industry ", VI International Scientific Conference. - Kaliningrad: Publishing house of BGARF FGBOU VO "KSTU", 2018. - pp. 61-67).

A significant drawback of this system is that the signal that all crew members are in the citadel is transmitted simultaneously with the notification via the ship's speakerphone. However, it is possible that the pirates will board the ship before the whole crew takes refuge in the citadel, which will allow the pirates to take hostages. In this case, the military will be misinformed about the presence of hostages, which can lead to the death of the latter during the storming of the ship in order to free it from pirates. In addition, even if the entire crew has taken refuge in the citadel, pirates can transport the ship to their base either by using the hijacked ship's own propulsion system or by towing it using the mother ship. Thus, the ship's crew will be held hostage at the pirate base, and will be held pending ransom.

The invention solves the problem of increasing the safety of navigation, preventing the abduction of the ship by pirates and its transportation to the base of the pirates, by blocking the propeller-rudder complex of the ship and the ship's power plant, as well as controlling the arrival of all crew members to the citadel.

To obtain the necessary technical result, it is proposed to equip the warning system about the approach of pirate-hazardous targets with a device for moving the rudder to the extreme position, devices for automatically blocking the propeller shaft and rudder stock, connect the interface device with the electronic control unit of the ship's power plant, and also install a crew arrival control sensor in the citadel and a third voice announcer containing the message that all team members have taken refuge in the citadel.

In the proposed technical solution, when the ARPA detects targets rapidly moving in the direction of the vessel, the system issues an alarm signal to the interface device, which connects the second voice annunciator to the ship's loudspeaker communication and to the ship's emergency communication, and the first voice annunciator to the VHF radio station keeping watch on the sixteenth channel, to transmit the message that the ship was attacked by pirates, and the evacuation of crew members to the shelter is underway. After receiving a signal about the arrival of all team members in the citadel, the interface device connects the third voice annunciator to the VHF radio station keeping watch on the sixteenth channel to transmit the message that all team members have taken refuge in the citadel; gives the ship's power plant electronic control unit a command to stop the engine, connects the rudder transfer device to the extreme position, and after stopping the engine and turning the rudder, activates the propeller shaft and rudder stock blocking devices.

The design of the maritime security system consists of an automatic radar plotting device (ARPA) 1 connected with information sensors 6: navigation radar station 9, vessel coordinates determination devices (GLONASS / GPS) 10, vessel heading device 11, vessel speed determination device 12. Also The ARPA is connected with the interface and switching units 7 and the notification and external signaling units 8. The interface and switching units 7 include: the first voice annunciator 13, the second voice annunciator 14, the third voice annunciator 15, the interface device 26, the switch for switching on the external alarm 16. Announcement and external alarm units 8 include: VHF radio station keeping watch on the sixteenth channel 17, ship loudspeaker communication 18, ship emergency communication 19, external loudspeaker connected to ship loudspeaker communication 20, external loudspeaker connected to ship emergency communication 21, external light annunciator, connected to the ship's emergency communication 22, the antenna of the ship's VHF radio station 23. The interface device 26 is connected to the electronic control unit of the ship's power plant 2, the automatic blocking device for the propeller shaft 3, the device for moving the rudder to the extreme position 5, the device for automatically blocking the rudder stock 4, and with a sensor 24 for monitoring the arrival of the crew in the citadel 25.

The maritime security system works as follows. If the system is activated, it monitors potentially dangerous targets. Signals from the navigation radar station 9, the ship positioning devices (GLONASS / GPS) 10, the ship heading device 11, the ship speed device 12 are sent to the automatic radar plotting device (ARPA) 1. The officer in charge of the watch sets a safe detection radius in ARPA 1 targets moving quickly towards the vessel.

When capturing a target rapidly moving in the direction of the ship, ARPA 1 issues an alarm to the interface 26, which, in turn, connects the second voice annunciator 14 to the ship's loudspeaker communication 18 and to the ship's emergency communication 19. In the second voice annunciator 14 connected to the ship's loudspeaker 18, a message is recorded about the immediate cessation of all work and evacuation to citadel 25, the last captain leaves, ensuring that all doors and hatches leading to citadel 25 are closed.

The interface 26 also connects the first voice annunciator 13 to the VHF radio station 17 keeping watch on the sixteenth channel. In the first voice annunciator 13, a message is recorded in advance about a pirate attack and that the ship's crew is being evacuated to citadel 25. This message on the sixteenth channel is broadcast with the message of the ship's position coordinates, which are automatically received from the ship's coordinates determining devices (GLONASS / GPS ) ten.

In addition, on the upper deck, an external warning light 22 connected to the ship's emergency communications 19 and an external loudspeaker 21 connected to the ship's emergency communications 19 are automatically activated. These measures are necessary to quickly find the hijacked vessel and psychological impact on the pirates.

After the captain closes the door leading to the citadel 25, the interface 26 receives a signal from the sensor 24 for monitoring the arrival of the crew in the citadel 25. According to this signal, the interface 26 connects the third voice annunciator 15 to the VHF radio station 17, which is keeping watch on the sixteenth channel. In the third voice annunciator 15, a message is recorded in advance that the entire crew took refuge in citadel 25.

In addition, after receiving a signal from the sensor 24 for monitoring the arrival of the crew in the citadel 25, the interface 26 locks the electronic control unit of the ship's power plant 2, and also activates the automatic blocking device for the propeller shaft 3. This will not allow the ship captured by the pirates to move under its own power to the port. which is the base of the pirates, even if they manage to launch the ship's power plant, overcoming the blocking of the electronic control unit of the ship's power plant 2.

At the same time, the interface device 26 connects the rudder shifting device to the extreme position 5 to rotate the rudder to the extreme left or right position, which will not allow the pirates to tow the hijacked ship to the port where they are based. After turning the rudder to the extreme position, the interface device 26 connects the automatic blocking device of the rudder stock 4, which fixes the rudder in the extreme position.

As a result of these actions, the ship captured by pirates will not be able to quickly leave the area in which it was attacked, and the coordinates of which were automatically transmitted via the sixteenth VHF channel. Given this and the fact that the entire crew of the ship took refuge in Citadel 25, the military will be able to effectively carry out the assault on the ship.

Thus, the proposed maritime security system avoids the capture of the hostage ship and its transportation to the port where the pirates are based. This increases the safety of vessels, in particular fishing vessels, in those areas of the world's oceans where pirates are active.
