A disadvantage of the known technical solution is that it does not provide sufficient emergency stability, which reduces the survivability, durability and efficiency of the ship.

Patrol-hydrographic ships are also known (Khramushin V.N. Exploratory studies of the stormy seaworthiness of the ship. Vladivostok: Dalnauka, 2003. 172 p. [5], Khramushin V.N. Proceedings of the First Sakhalin Scientific and Technical Conference on February 12, 2008, Yuzhno-Sakhalinsk, SakhSU publishing house, 2008 [6], GB patent No. 1166976 A, 10/15/1969. [7], US patent No. 5711239 A, 27.01 .1998 [8], patent RU No. 2384456 [9]).

The famous patrol-hydrographic ship of increased storm seaworthiness for the open ocean is designed for all-weather service in the Far Eastern seas of Russia; continuous and comprehensive monitoring of the state of marine water areas; monitoring the surface and underwater conditions in the open sea and near the coast of Sakhalin and the Kuril Islands, including the ability to provide continuous solution to search and research problems, conduct marine reconnaissance, hydrographic and hydrometeorological support of the fleet; as well as in cooperation with the coastal maritime services, it is effective to solve the tasks of saving human life at sea and providing information on the safety of navigation in the stormy conditions of the Far Eastern seas of Russia and the north-western Pacific Ocean (patent RU No. 2384456 [9]).

The subject of the invention [9] is a ship of unlimited navigation area, the shape of the hull and general ship architecture of which provide the best stormy seaworthiness in all weather conditions of long ocean voyages, which is expressed in the possibility of maintaining high speed with any course relative to hurricane wind and storm waves with a minimum of airborne and pitching, and, as a result, capable of effectively using all onboard and outboard technical surveillance equipment and naval weapons.

The ship is a surface craft with a buoyancy margin not exceeding the displacement, without zygomatic and bottom keels or other active wing stabilizers of pitching in the middle of the hull. Two options for installing a podcast sonar station are considered: in the middle part of the hull in the form of a retractable well-streamlined nacelle mounted on two narrow racks that do not affect the transverse flows of water during on-board rolling of the ship, and in the nose cowl fairing, which, nevertheless, there is a stem cut to facilitate the yaw of the ship in conditions of intense storm waves.

On board the ship there are anti-ship and anti-aircraft weapons, radar systems for monitoring the surface situation and special hydrometeorological observation systems; a feed ramp for launching a large autonomous or towed watercraft, as well as hydrophysical and hydrographic search equipment, including those presented by self-propelled surface and underwater vehicles and towed paravanes. When conducting underwater prospecting or hydrographic work, the ship is able to form a wide field of self-propelled and towed hydrophysical stations, providing coverage of a large area of sea water for one tack.

To coordinate the whole complex of tasks facing the ship, technical solutions were implemented in its design in accordance with the principles of consistent design of complex marine engineering structures and good marine practice.

In the middle of the hull there is a blockage of the side with a maximum angle of inclination of the frames at the level of the current waterline. The longitudinal distribution of the height of the side of the ship is made in such a way that in stormy conditions on any part of the side, approximately the same amount of water can be poured onto the upper deck of the ship. On the ship, superstructures are not installed across the width of the deck from one side to the other, and all large over-deck structures are made in the form of cuttings with a single wide passage along the length of the ship in the middle of the mid-frame. This means that when the wave crest is swept onto the ship’s deck, relatively narrow deckhouse and coaming prevent the flow of water to the leeward side, the whole mass will remain on the same side, which creates an additional straightening moment after the wave hits the ship’s side.

The ship has a cruise stern, while the entire aft part of the hull has a blockage of the freeboard, which is necessary to exclude the capture of the hull by a passing wave and to prevent broaching. The feed aperture is short and does not form an excess free water volume hanging above the water, which is possible when using the twin-shaft propeller complex scheme. Directly behind the propellers, spring-loaded horizontal wings of active pitching stabilizers are installed, which, when the main engines are stopped, begin to work as stormy flapping wing propulsors that perceive the energy of the vertical movements of the stern of the ship relative to the surface of the water that occurs when the ship keels intensively without moving.

The underwater part of the stem has an oblique undercut, and the surface branch of the stem is piled into the stern, which is necessary to relieve shock loads on the hull when cutting through wave crests at full speed of the ship. The jammed stem always cuts the crests of the waves at an obtuse angle, and the underwater stem cut allows spontaneous deviation from the course (yaw), which also eliminates concentrated wave impacts on the collapse of the cheekbone of the freeboard. The branches of the surface frames in the bow of the hull have a small camber, which is necessary to exclude the deep diving of the upper deck under the crests of large storm waves at full speed of the ship. The underwater branches of the nasal frames create a swirling surface starting from a small obstruction of the side above the bulb, smoothly directing water flows under the bottom of the ship. Such a nasal cheekbone pulls down and extinguishes the crest of the first diverging ship wave and similarly passes oncoming storm waves under the bottom, preventing them from concentrating blows on the ship's hull.

The shoulder diagram of the static stability of the hull shape due to the concave freeboard in the middle of the hull has a pronounced S-shape. The sunset angle of the stability diagram for a ship without deckhouse goes 180 °, which formally means absolute stability, eliminating the fundamental possibility of sailing the ship upward by a keel. Adding the volume of deck felling to the calculations of restoring moments at large roll angles shows the practical impossibility of the ship toppling over.

To assess the behavior of a ship on waves, we introduce the concept of an active waterline band, which for this ship will be ± 1.25 m. In this band, the force action of sea waves with a height of the order of 3-4 m will be manifested.

The general architectural solution for the ship is represented by the inclusion of all deckhouses and devices inside the overall circular cylinder, except for the central cabin with a navigation bridge. Niches for storage and quick descent of self-propelled hydrophysical modules and paravanes are located on the high cabin island, external aerial surveillance systems are installed above the cabin. All domestic and office premises are located inside a sealed hull, the upper deck of which is the main waterproof deck of the ship. Along the starboard side there is a through corridor, divided by automatic doors on watertight bulkheads, all residential and office premises are located on the port side. Ship machinery and equipment, cargo areas and tanks for liquid cargo are located below the upper residential tier in the ship's hull.

Experimental nautical tests of a self-propelled telecontrolled model of a ship in a test basin on regular waves, as well as tests on real wind waves in the open sea, fully confirmed the correctness of the selected technical solutions in the form of the hull and general ship architecture:

- course losses during the movement of the ship at an arbitrary course relative to steep waves, the height of which exceeded the height of the ship's hull together with superstructures, do not exceed 25-30%;

- the side rolling both at full speed of the ship and when the cars are stopped remains minimal, which was clearly manifested in comparison with the slopes of the surface of storm waves;

- trim angles and vertical accelerations in the extremities of the ship comprise 20-30% of the natural vertical accelerations of fluid particles on the surface of the water and, accordingly, the visible inclinations between ridges and troughs of storm waves;

- even under the influence of large crests of storm waves striking the central deckhouse and completely covering other lower deck structures, the ship did not undergo large heeling.

The shape of the ship's hull and general ship architecture of the ship as a whole satisfy the principles of consistent design of the ship, coordinating all technical solutions without mutual contradictions.

However, providing assigned tasks to the hydrographic and patrol service ship dictates the need to equip it with the appropriate navigational and hydrographic weapons, which are not fully represented on the well-known hydrographic and patrol service ship [9].

Figure 3. Scheme of aeration of the flow of water under the ship. The scheme includes a frame 37, aeration pipe 38, air intakes 39. The aeration pipe 38, in its part extending relative to the bottom of the vessel, is perforated.

Figure 4. Screw nozzle: 40 - screw, 41 - diffuser, 42 - deflecting surface, 43 - holes.

Figure 5. The removable rigid container 11 for receiving liquid hydrocarbons consists of a tank 44, equalization tanks 45, a gate valve 46, a receiving manifold 47, a suction pump 48, a reinforced sleeve 49, connected by a cable 50 to a two-link tethered remote control underwater vehicle 16.

The underwater part of the stem has an undercut that promotes free yaw of the bow of the ship's hull under intense storm waves. The stem is piled up in the stern to provide oblique cutting of the wave crests while the ship is moving and to prevent the bow of the hull from taking off above the surface of the water. Forage cruising, with full aft clearance for a twin-screw main propulsion scheme. In the stream behind the propellers, horizontal wings of active pitching stabilizers with spring-loaded ballers are installed, which, when the stroke is lost, begin to work as storm emergency propulsors. The steering wheel is semi-balanced, located in the diametrical plane of the ship. The ship is equipped with a main caliber gun, four container-type missile silos and two high-speed anti-aircraft guns. Scientific-research equipment is represented by four paravanes or self-propelled vehicles with cable control. In the stern there is a hangar and a ramp for launching large-sized self-propelled or towed vehicles.

To reduce the negative pressure under the ship when sailing in shallow water, a scheme of aeration of the flow of water under the ship is provided, which includes a frame 37, aeration pipe 38, air intakes 39. The aeration pipe 38 is perforated in its part extending relative to the bottom of the vessel.

The manifestation of negative pressure under the bottom of the ship causes the occurrence of additional precipitation ΔТ and a differential angle α. The manifestation of these factors leads to a decrease in the depth reserve under the ship and even to the landing of the ship at the bottom of the ship's passage, and the appearance of a trim angle leads to a significant increase in the resistance to movement of the ship.

To reduce (or completely eliminate) these adverse factors, it is necessary to neutralize the negative pressure under the ship when sailing in shallow water. This can be done by aeration of the flow under the ship in the zone of high negative pressures or by supplying water under the bottom.

During the movement of the ship, when areas of lowered (negative) pressure arise, air is sucked into the aeration pipe 38 through the air intakes 39 and through the perforated lower part it enters the stream under the ship.

Improving the efficiency of the use of ship 1 of the hydrographic and patrol service is closely associated with an increase in the efficiency of propulsors. As you know, the efficiency of an ideal propulsion can be determined by the ratio:

where L = mωaV _p is the net power developed by the propulsion device;

- затраченная мощность,

- consumed power

m is the mass of fluid flowing through the mover per unit time;

V _p is the velocity of the unperturbed liquid;

ω _a is the speed caused by the propulsion device at infinity.

Formula (1) shows that the greater the induced velocities ω _a , the smaller η. Thus, the problem of increasing η can be solved by reducing ω _a . This can be achieved by equipping the screws with diffuser nozzles with a slope of water from the inner surface of the nozzle (figure 4).

The use of a diffuser screw nozzle with a slope allows you to provide the following conditions;

- expansion of the discarded jet with the simultaneous alignment of the velocity plot and a significant decrease in the velocity ω _a ;

- increase the efficiency of the propulsion;

- a decrease in the speed (and quantity) of the satellite stream (for ω _a = -V _{a, the} theoretical satellite stream can be completely neutralized);

- decrease in the energy of the stern wave group.

To increase the suction effect, vacuum pumps can also be used.

The external fire extinguishing system 9 is designed to extinguish fires at objects of marine economic activity, for example, offshore oil and gas terminals located in the patrol area.

The helicopter 8 is designed both for patrol operations and for rescue operations at offshore economic facilities.

Removable rigid containers 11, each with a volume of 350 m ^3, are designed to accept liquid hydrocarbons when they leak from trunk pipelines. In this case, when leaks from the main pipeline are detected, by means of a two-link tethered remote control underwater vehicle 16 connected by a cable cable 50 to a removable rigid container 11, a removable rigid container 11 is installed above the leak, and liquid hydrocarbon (oil or fuel oil) flows by gravity through the receiving the collector 47 into the tank 44. Upon filling the tank 44, the valve 42 is activated and the tank is transported to the collector by means of a two-link remote-controlled underwater vehicle 16 petroleum products, in which the collected petroleum products through a pumping pump through a reinforced sleeve 49 enter the tankers of the collector of petroleum products.

An analogue is the two-link tethered remote-controlled underwater vehicle of the Trepang-2MT type, designed to search and examine underwater objects at depths of up to 2500 m with a towing speed of 2-5 knots.

In a specific embodiment, a two-link tethered remote control underwater vehicle 16 consists of two modules, one of which is a towed module, and the other is self-propelled. In this case, the towed module is equipped with a side-scan and sector-based sonar; scanning profiler; noise finder gas leaks; dissolved hydrocarbon analyzer. The self-propelled module is equipped with a color television camera, a current and potential meter. The towed module is connected to the hydrographic and patrol service ship 1 with a cable 5 km long and 26 mm in diameter. The communication cable between the towed module and the self-propelled module has a length of 100 m and a diameter of 10 mm.

When staging hydrographic and patrol services from ship 1 and when boarding, both modules are connected into a single whole. In towing mode, the self-propelled module is connected either to the towed one or moves behind the towed one when it is separated from the ground by up to 10 m.

At the foot of ship 1 of the hydrographic and patrol service in the dynamic positioning mode, the towed module hangs above the ground, and the self-propelled module moves around the towed module.

On both modules are located the nodes of office equipment: power supply, communication lines, control, underwater navigation, including depth, course, echo sounders, sonar transponders.

On the towed module, propulsion and propulsion systems are provided for lagging (lateral) movement, ensuring retention at a given lateral distance from the pipeline, as well as a “garage” and a winch for the self-propelled module.

To obtain a sonar image of the bottom and its profiling, the ship 1 of the hydrographic and patrol service tows the device at a given distance from the ground. At the same time, side view and / or sector view sonars and a profiler work. The coordinates of ship 1 of the hydrographic and patrol service are determined using satellite navigation equipment, and the position of the towed module relative to the vessel is determined using the ship’s sonar navigation system interacting with the transponder beacon on the device. The lateral displacements of the towed module are compensated simultaneously by the maneuver of ship 1 of the hydrographic and patrol service and the lag propulsion and propulsion systems of the device. The vertical displacements of the towed module are worked out by changing the length of the load-carrying cable. For a television inspection, ship 1 of the hydrographic and patrol service gives a stop and performs dynamic positioning. The self-propelled module is separated from the towed and maneuvers around it.

When monitoring the pipeline, the apparatus is towed along it. In open areas, movement is carried out at some lateral distance using a side-scan sonar. In areas where the pipeline is buried in the ground, the apparatus moves above it using a profilograph in scanning mode. In this case, the bottom profile is determined at a distance of 10-15 m from each side of the pipeline at certain intervals.

A television inspection and control of the pipeline is carried out by a self-propelled module when the ship 1 of the hydrographic and patrol service is in a dynamic positioning position. The position of the self-propelled module relative to the towed one is determined using a transponder beacon mounted on the self-propelled module.
