Description

Technical Field

[0001] The present invention relates to the technical field of pressure-displacement loading of semi-submersible carrier equipment, and in particular to a matrix point-controlled partitioned mixed pressure-displacement loading system for semi-submersible carrier equipment. Background Art

[0002] With the growing demand for global marine engineering, offshore wind power, oil and gas platforms and other large marine structures, the tonnage of semi-submersible transport equipment has gradually increased, and the total capacity of ballast tanks has become larger and larger. The existing single ballast discharge method is difficult to meet the demand for rapid discharge of large-capacity ballast water. In addition, semi-submersible transport equipment faces extremely complex working conditions and environmental challenges during diving and surfacing operations, including the variability of marine climate, uncertainty in cargo shape and weight, and changes in the ship's own motion posture. More importantly, the operating time window of semi-submersible transport equipment is often very short, and key operations such as diving, surfacing and cargo transfer need to be completed within a limited time. Therefore, extremely high requirements are placed on the intelligence and efficiency of the ballast discharge system.

[0003] The existing semi-submersible carrier equipment pressure discharging system mainly adopts a single pressure discharging method of compressed air, gravity or pump pressure discharging, and is realized through prior loading calculation and manual operation. This process is not only inefficient, but also highly dependent on the operator's experience and skills, and there are great safety hazards. Especially in severe sea conditions, factors such as the ship's position and posture, the actual shape, weight and loading position of the cargo often deviate from the ideal state calculated in advance, increasing the risk and difficulty of operation. In order to achieve efficient and safe operation of semi-submersible carrier equipment under complex sea conditions and short operation time windows, its pressure discharging system must be upgraded. Summary of the invention

[0013] Each compressed air pipe is equipped with an intelligent control unit, a compressed air valve and a breathable valve. Each cabin is independently equipped with an electro-hydraulic pressure control valve and a sea-going pipeline of the intelligent control unit, which serves as the gravity pressure discharge pipeline of each cabin and also serves as the warehouse through pipe of the pump ballast auxiliary pipeline.

[0014] As a preferred technical solution, each ballast compartment is equipped with a temperature sensor, a pressure sensor, and a liquid level sensor, which transmit the collected temperature, pressure and liquid level information of each ballast compartment to the ballast load automatic monitoring module.

[0015] As a preferred technical solution, the ballast compartment is optimized by symmetrically arranging air compressors and compressed air main pipes in the left and right compartments.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example

[0031] like Figure 1 As shown, the present embodiment provides a matrix point-controlled zoned hybrid pressure-discharge loading system for semi-submersible transport equipment, including three subsystems: compressed air pressure-discharge loading, gravity pressure-discharge loading and pump pressure-discharge loading. Among them, compressed air pressure-discharge loading is the main system, gravity pressure-discharge loading and pump pressure-discharge loading are supplementary systems, which are zoned and arranged in each compartment of the semi-submersible transport equipment. The same compartment can simultaneously adopt a mixed compressed air / gravity pressure-discharge loading mode or a pump / gravity pressure-discharge loading mode, which can greatly improve the pressure-discharge loading efficiency; each ballast compartment is accurately and independently managed and controlled through a matrix point-controlled control mode, so as to realize flexible and precise control; and it is equipped with a rapid ballast water treatment module and a ballast water automatic monitoring module, which meets the ballast water discharge convention and improves the intelligence level of the system.

[0032] In this embodiment, the compressed air pressure discharge system includes a ballast compartment unit, an air compressor module, an intelligent pressure discharge monitoring module, a matrix point control module, a compressed air gas collection main unit, an air pipe remote-controlled butterfly valve unit, a seawater pipe remote-controlled butterfly valve unit and a pipeline module; by supplementing the auxiliary pump pressure discharge and gravity pressure discharge methods in different areas of the semi-submersible carrier, rapid zoned mixed pressure discharge is achieved. The air compressor module is arranged in a dedicated air compressor cabin, and the compressed air is distributed to each compartment through the gas collection main and independent air pipes of each compartment. The compressed air pressure discharge compartment is located in the middle of the semi-submersible carrier, and the pump pressure discharge compartment is located at the bow and tail of the semi-submersible carrier. In addition, the two higher compartments at the bow are selected as clean ballast water compartments to ensure effective water quality management.

[0033] In this embodiment, a compressed air pressure discharging subsystem is used as the main system. A compressed air pipe is independently configured in each ballast compartment of the semi-submersible carrier, and then connected to the air collecting main pipe in the air compressor compartment; each compressed air pipe is provided with an intelligent control unit, a compressed air valve and a breathable valve. Each compartment is independently provided with a sea-going pipeline equipped with an electro-hydraulic pressure control valve and an intelligent control unit, which can be used as a gravity pressure discharging pipeline for each compartment and also as a through-compartment pipe for the pump ballast auxiliary pipeline, meeting the requirements of zoned mixed pressure discharging.

[0034] like Figure 2 As shown, the ballast load automatic monitoring module includes a data acquisition unit, a data transmission unit, a data processing unit and an output display unit. By arranging temperature, pressure, and liquid level sensors in each ballast compartment to monitor the real-time ballast water changes and check the conditions of each compartment, real-time information feedback is provided for the semi-submersible carrier to quickly discharge water. The collected feedback information will be transmitted to the matrix point control module of the semi-submersible carrier. According to the current ballast load status, the control parameters will be adjusted in real time and sent to the air compressor compartment, thereby adjusting the air injection volume and speed of the air compressor module to ensure the safety and stability of the entire ballast load process.

[0035] like Figure 3 As shown in the figure, the ballast load automatic monitoring module can monitor the liquid level sensors in each ballast tank of the semi-submersible carrier equipment, and track the dynamic changes of the ballast water volume in real time during the ballasting process, so as to realize the calculation of the intelligent control of the equipment and provide feedback information. The module can correct the collected tank height data based on the pre-set ship parameters (such as tank volume and hull type value), thereby reducing the error in the data collection process. The data acquisition module is mainly responsible for obtaining the liquid level, pressure and temperature information of each ballast tank. The signal captured by the sensor is transmitted to the data acquisition station through a cable, and then transmitted to the control system center according to the communication protocol. Finally, the relevant data is displayed on the computer of the system workstation, and an alarm prompt is issued for abnormal signals.

[0036] In this embodiment, the matrix point control module includes a control center unit, a data processing unit, an execution unit, and a communication unit. By collecting monitoring data information from each ballast compartment and pipeline module, independent and precise control of the ballast compartment is achieved.

[0037] In this embodiment, the layout of pipelines and equipment is simply and quickly optimized based on the semi-submersible transport equipment, including the optimization of the ballast compartment partition system, the optimization of the layout of the air compressor and the gas collecting main pipe, and the optimization of the system pipeline merger.

[0038] In this embodiment, the ballast compartment partition system is optimized to symmetrically arrange the air compressor modules and the compressed air collecting main pipe unit in the left and right compartments. The left compartment is connected to the collecting main pipe of the left air compressor compartment through pipelines, and the right compartment is connected to the collecting main pipe and air compressor module on the right side; Figure 4 As shown, the layout of the air compressor and the air collecting main pipe is optimized. The air compressor unit, steam-water separator and cooler in the air compressor cabin are arranged in a straight line in the compact cabin. The air collecting main pipe is arranged horizontally, and most of the pipelines are placed under the air compressor cabin to ensure sufficient ground space for easy inspection and maintenance. The system pipeline merger is optimized, and the air pipes are arranged symmetrically in the left and right cabins. The air main pipe and the overflow pipeline are merged into one, and the traditional overflow branch pipe is eliminated.

[0039] In this embodiment, high-pressure large-diameter polyethylene pipes (PE pipes) are widely used in the air pipelines and ballast water pipelines of the ballast system. PE pipes have excellent ductility, so that expansion joints and omega bends can be omitted in straight and long pipelines. In addition, PE pipes also have excellent corrosion resistance. In order to ensure the watertightness between the two cabins, galvanized steel pipes are used for the through-cabin pipes and are connected to the PE pipes through flanges. A cooler and an intelligent monitoring unit are added at the compressed air outlet of the air compressor to ensure that the compressed air temperature is controlled within the normal working temperature range of the PE pipe. An ultrasonic guided wave monitoring system is also installed in the pipeline to monitor the health status of the pipeline in real time.

[0040] In this embodiment, the rapid ballast water treatment module is arranged in the pump ballast replenishment system, an electrolytic ballast water treatment device is adopted, and a ballast main is arranged to each ballast tank, and an electro-hydraulic remote-controlled butterfly valve is arranged in each tank. The ballast water pump draws seawater from the outer seawater through the seawater main, injects it into the clean ballast tank after treatment, and then flows into each ballast tank by gravity. The sodium hypochlorite produced by electrolysis in the electrolytic ballast water treatment device can continue to play a role in the ballast tank, has a good inactivation effect, and will decompose itself over time. Usually, ballast water stored in the ballast tank for more than 3 days can be discharged directly without secondary treatment to ensure the ballast discharge efficiency.

[0041] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
