Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of ship hull monitoring, in particular to a ship fouling monitoring system. BACKGROUND

[0002] Due to long-term exposure to seawater, long-distance ships are eroded by seawater and marine organisms, which easily causes many organisms to climb on the bottom of the ship, resulting in corrosion of the ship's hull, continuous decline of the ship's hull shear force, strength and bending moment, and even endangering the safety of the ship's navigation, and even causing major maritime accidents.

[0003] At the same time, the ship fouling also increases the sailing resistance, and the fouling makes the ship surface rough, increasing the frictional resistance and vortex resistance during sailing. Studies have shown that for every 25 microns increase in ship bottom roughness, fuel consumption will increase by 2%-3%, and speed will decrease by 1%. The ship fouling also reduces the speed, and due to the increase of fouling resistance, the ship speed will decrease accordingly under the condition of constant main engine power. This will cause the ship to be unable to arrive at the destination on time, affecting the shipping plan and operation efficiency.

The cooperation of the sonar sensor 31 and the optical imaging sensor 32 is as follows: the sonar sensor 31 is used to detect the ship bottom condition in a large range, and obtain the preliminary shape and thickness information of the ship bottom. The optical imaging sensor 32 provides high-resolution ship bottom images for identifying the specific type and distribution range of the fouling. The cooperation mode is as follows: first, the sonar sensor 31 is used for preliminary screening to determine the suspicious areas, and then the optical imaging sensor 32 is used for detailed shooting and analysis of these areas, so as to improve the accuracy and efficiency of the monitoring.

[0052] Specifically, the cooperation between the laser displacement sensor 33 and the pressure sensor 24 is as follows: the laser displacement sensor 33 is used to measure the slight changes in the surface of the bottom and detect the increase in the roughness of the surface. The pressure sensor 34 is used to monitor the changes in the water pressure distribution at different positions of the bottom. The cooperation mode is as follows: when the laser displacement sensor 33 detects the abnormality of the roughness of the surface, the data of the pressure sensor 34 can help further analyze the influence of the fouling bottom on the hydrodynamic performance of the bottom, so as to more comprehensively evaluate the fouling bottom.

[0053] With reference still to Figure 2 Optionally, the monitoring device 3 comprises at least two ultrasonic sensors 35.

[0059] Figure 3 is a side view of a ship fouling monitoring system according to an embodiment of the application, Figure 4 is a top view of a ship fouling monitoring system according to an embodiment of the application, and the arrangement of sensors is as shown in Figure 3 and Figure 4 .

[0060] Determine the monitoring area: the centerline area of the ship bottom: it is the area directly impacted by water flow when the ship is sailing, and it is one of the places where fouling organisms are more likely to attach, so sensors need to be arranged. The bow and stern areas: sensors are arranged near the bulbous bow of the bow and the propeller and rudder of the stern, so that the fouling conditions of these areas can be found in time. The two sides of the ship bottom: the bilge and keel near the bilge of the two sides of the ship bottom are also places where fouling organisms are easy to attach, so sensors need to be arranged regularly.

[0061] Sensor arrangement: grid layout: in the relatively flat area of the ship bottom, sensors are arranged in an equal interval manner to form a grid layout, achieving uniform monitoring of large areas of the ship bottom. Dense arrangement in key areas: in areas where fouling organisms are more likely to attach, the density of sensor arrangement is increased to more accurately monitor the fouling conditions of these key parts. Arrangement along the water flow direction: according to the flow direction and distribution law of water flow on the ship bottom when the ship is sailing, sensors are arranged along the water flow direction.

[0062] Installation method: bolt fixation: suitable installation positions are designed in advance on the ship structure, and sensors are fixed to the ship bottom through bolts. This method is firm and reliable, and is suitable for most types of sensors. Welding installation: for sensors that need to be installed more firmly, they can be fixed to specific positions on the ship bottom by welding.

[0063] Environmental factor considerations: water flow impact: In areas where water flow impact is greater, such as the bow of the ship, choose sensors with higher strength and impact resistance, and take appropriate protective measures, such as adding protective covers or cushioning devices, etc. Corrosive environment: the shell of the sensor should be made of corrosion-resistant materials, such as stainless steel, titanium alloy or special corrosion-resistant alloy; at the same time, the contact parts between the sensor and the ship body and the cable interface, etc. should be well treated, such as applying anti-corrosion glue, installing anti-corrosion seals, etc. Biological attachment: the surface of the sensor should be as smooth as possible to reduce the possibility of dirt attachment; at the same time, some anti-fouling coatings or regular cleaning measures can be taken to keep the sensor surface clean.

[0064] Optionally, the ship's fouling monitoring system further comprises an axle power meter or a rotating speed sensor;

[0065] The axle power meter or the rotating speed sensor is installed inside the ship, and the axle power meter or the rotating speed sensor is connected with the ship's fouling monitoring display center. The axle power meter or the rotating speed sensor is used to collect the main engine power data in real time, and the main engine power data is transmitted to the ship's fouling monitoring display center in real time.

[0066] Optionally, the ship's fouling monitoring system further comprises a main engine inlet and outlet fuel flow meter;

[0067] The main engine inlet and outlet fuel flow meter is installed inside the ship, and the main engine inlet and outlet fuel flow meter is connected with the ship's fouling monitoring display center. The main engine inlet and outlet fuel flow meter is used to collect the fuel consumption in real time, and the fuel consumption data is transmitted to the ship's fouling monitoring display center in real time.

[0068] The ship's fouling monitoring display center is used to analyze the relationship between fuel efficiency and main engine load according to the main engine power data and fuel consumption data, and to evaluate the impact of fouling on the fuel economy of the ship.

[0069] Specifically, the axle power meter or the rotating speed sensor is used to provide the main engine power of the ship, the main engine inlet and outlet fuel flow meter is used to provide the fuel consumption data of the ship, and the ship's fouling monitoring display center is mainly used to calculate the fuel efficiency-main engine load relationship.

[0070] The increase in ship resistance caused by fouling will increase the load of the main engine, increase fuel consumption and reduce efficiency. The ship's fouling monitoring display center calculates and analyzes the relationship between main engine fuel efficiency and main engine load according to the fuel efficiency-main engine load relationship curve method, which can evaluate the impact of fouling on the fuel economy of the ship.

[0071] The calculation formula of fuel efficiency-main engine load is:

[0072]

[0073] Wherein, fd is the fouling coefficient, indicating the percentage of the main engine power increase caused by the fouling, Psd is the measured main engine power, and Ps0 is the main engine power when the ship is clean at the same speed.

[0074] Optionally, the ship fouling monitoring system further comprises a log;

[0075] The log is installed inside the ship, and the log is connected to the ship fouling monitoring display center, and the log is configured to provide the speed of the ship against water to the ship fouling monitoring display center, and the ship fouling monitoring display center is configured to analyze the relationship between the main engine power and the speed, and to evaluate the impact of the fouling on the performance of the ship.

[0076] Specifically, there is a certain relationship between the main engine power and the speed of the ship, when the ship bottom attachment increases, the ship resistance increases, and the main engine needs to output more power to maintain a certain speed. The ship fouling monitoring display center can evaluate the impact of the fouling on the performance of the ship by calculating and comparing the changes of the main engine power of the ship at different speeds according to the power-speed relationship curve method.

[0077] The calculation formula of the power-speed relationship is as follows:

[0078]

[0079] Wherein, P is the main engine power, F is the total resistance of the ship, v s is the speed of the ship against water, and η p is the propulsion efficiency of the ship.

[0080] The above specific embodiments do not constitute a limitation on the scope of protection of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
