Technical Field
[0001] This invention relates to the field of marine energy utilization technology, specifically to a method, system, equipment, and medium for offshore operations. Background Technology
[0002] With the increasing frequency of activities such as marine resource exploration, deep-sea transportation, and island development, higher demands are being placed on the ability to conduct sustained and stable offshore operations. A reliable power supply is crucial to ensuring the continuous operation of various offshore equipment (such as monitoring buoys, communication relay stations, and seawater desalination plants). Currently, power supply for offshore operations mainly relies on shore-based power grid extensions, onboard fuel generators, and solar photovoltaic systems.
[0003] However, all of the aforementioned existing power supply solutions have significant limitations. Shore-based power supply is costly and has extremely limited coverage; fuel-fired generators not only have high operating costs and require frequent refueling, but also pose risks of noise, pollution, and fire; solar power is greatly affected by day and night and weather conditions, resulting in poor power supply stability and requiring large-capacity energy storage batteries, which increases system complexity and cost. Crucially, none of these solutions effectively utilize the vast renewable energy resources available in the ocean. Therefore, developing a locally sourced, continuous, stable, economical, and environmentally friendly offshore power supply method has become a pressing technical bottleneck that needs to be addressed in this field.

[0025] Figure 1This application illustrates an embodiment of a marine operation method, the method comprising: Step 101: Collect the mechanical energy of ocean waves and convert the mechanical energy into electrical energy; Step 102: Generate an energy distribution scheme based on the energy output status and the load requirements of the electrical equipment; Step 103: Control the electrical equipment to perform the operation task according to the power distribution scheme.
[0026] To address the issues on the energy supply side, this application embodiment collects the mechanical energy of ocean waves and converts it into electrical energy, fully tapping into the abundant wave energy resources at sea, realizing the on-site utilization of renewable energy, and eliminating dependence on traditional power supply methods such as fuel oil and shore-based power transmission. At the same time, through the stable conversion of mechanical energy into electrical energy, it provides basic energy security for subsequent energy supply, reducing the energy costs and environmental impact of offshore operations.
[0027] To address the issue of matching energy supply with load, this application's embodiments generate an energy allocation scheme based on the energy output status and the load demand of electrical equipment, achieving dynamic and precise matching of energy supply and operational needs. Due to the volatility of wave energy at sea, energy output is unstable, and the load of electrical equipment in different offshore operations may change with the operational phase. Existing solutions that directly supply energy to equipment are prone to energy waste or insufficient supply. This step, by real-time correlation between energy output data and load demand to generate a targeted allocation scheme, effectively avoids the above problems, improves energy utilization efficiency, and ensures that electrical equipment receives an appropriate energy supply.
[0028] Furthermore, this application controls the electrical equipment to perform operational tasks according to the power distribution scheme, ensuring the continuity and stability of offshore operations. Offshore operations often have uninterrupted requirements (such as continuous communication and real-time monitoring), and power outages may lead to risks such as data loss and task failure. This application ensures that the electrical equipment always receives a stable and suitable power supply through the execution of the distribution scheme, and achieves coordination between the power supply system and the operational system by controlling the linkage logic of the operational tasks, thereby improving the overall operational reliability.
[0029] In one possible implementation, step 101, the acquisition of the mechanical energy of ocean waves, includes: acquiring motion data of the energy capture component in the wave energy acquisition device, the motion data including displacement or force data; determining the wave motion trend based on the motion data; and, based on the motion trend, acquiring the mechanical energy of the ocean waves by having the energy capture component bear the force of the waves.
[0030] In one possible implementation, to achieve precise and efficient wave energy harvesting, the harvesting of the mechanical energy of ocean waves in step 101 can be achieved as follows: first, the motion data (including displacement or force data) of the energy capture component in the wave energy harvesting device is collected; then, the wave motion trend is determined based on the motion data; finally, based on the determined wave motion trend, the energy capture component accurately absorbs the force of the wave, thereby completing the harvesting of the ocean wave's mechanical energy. Through the pre-processing logic of motion data monitoring and trend judgment, the energy capture component can be precisely matched with the wave motion, avoiding energy loss caused by blind harvesting.
[0031] In one possible implementation, in step 101, the conversion of mechanical energy into electrical energy includes: the energy-harvesting component moving linearly under the force of waves and transmitting the collected mechanical energy to the transmission component; the mechanical structure of the transmission component converting the motion form to convert the mechanical energy corresponding to the linear motion of the energy-harvesting component into the mechanical energy corresponding to the rotational motion of the generator rotor; and the generator rotor cutting magnetic field lines as it rotates, converting the mechanical energy corresponding to the rotational motion into electrical energy.
[0032] In a specific implementation, the energy harvesting component moves in a straight line under the force of the waves, transferring the collected mechanical energy to the transmission component. Then, the mechanical structure of the transmission component converts the mechanical energy corresponding to the linear motion of the energy harvesting component into the mechanical energy corresponding to the rotational motion of the generator rotor. Finally, the generator rotor, through its rotational motion, cuts magnetic field lines, converting the mechanical energy corresponding to the rotational motion into electrical energy. This step-by-step conversion logic from linear motion to rotational motion to electrical energy ensures the stability of the energy conversion process.
[0033] In one possible implementation, in step 101, the motion mode is converted through the mechanical structure of the transmission assembly to convert the mechanical energy corresponding to the linear motion of the energy-capturing component into the mechanical energy corresponding to the rotational motion of the generator rotor. This includes: identifying the linear motion direction of the energy-capturing component through the motion data; when the energy-capturing component is identified to be moving linearly away from the sea level, the transmission assembly receives the mechanical energy generated by the linear motion and operates in the forward direction, driving the generator rotor to rotate to convert the mechanical energy into electrical energy; when the energy-capturing component is identified to be moving linearly towards the sea level, the adjustment assembly is activated to output a reset force, causing the transmission assembly to rotate in the reverse direction, pulling the energy-capturing component to reset, preparing for the next reception of wave mechanical energy; the adjustment assembly includes an elastic reset component or a counterweight adjustment component.
[0034] Furthermore, a more detailed implementation method is adopted for the aforementioned process of the transmission component converting its motion form: The linear motion direction of the energy harvesting component is identified through motion data (displacement or force data); when the energy harvesting component is detected to be moving linearly away from the sea level, the transmission component receives the mechanical energy generated by this linear motion and rotates in the forward direction, directly driving the rotor of the power generation component to rotate, thus realizing the conversion of mechanical energy into electrical energy; when the energy harvesting component is detected to be moving linearly closer to the sea level, the adjustment component is activated to output a reset force, driving the transmission component to rotate in the reverse direction, thereby resetting the energy harvesting component and preparing it for the next reception of wave mechanical energy. The adjustment component includes an elastic reset component or a counterweight adjustment component. By accurately identifying the motion direction and matching differentiated transmission logic, it is possible to ensure the effective utilization of the positive force of waves for power generation, and the reset mechanism ensures the cyclic operation capability of the energy harvesting component, further improving the continuity and efficiency of wave energy harvesting and conversion.
[0035] In one possible implementation, in step 101, a one-way transmission component is provided on the mechanical energy transmission path between the transmission component and the power generation component; the one-way transmission component is used to allow mechanical energy to be transmitted in the direction that drives the rotor of the power generation component to rotate; a speed adjustment component is provided between the one-way transmission component and the power generation component; the speed adjustment component is used to receive the mechanical energy transmitted in one direction, adjust the rotational speed of the transmission component to the rotational speed adapted to the rotor of the power generation component, and transmit the mechanical energy corresponding to the adjusted speed to the power generation component to drive the rotor to rotate.
[0036] In one possible implementation, to further ensure the stability and efficiency of the conversion of mechanical energy to electrical energy, a one-way transmission component can be provided in step 101 along the mechanical energy transmission path between the transmission component and the power generation component. This one-way transmission component allows mechanical energy to be transmitted in the direction driving the rotor of the power generation component to rotate, effectively blocking reverse energy loss and preventing interference to the power generation process when the transmission component operates in reverse. Simultaneously, a speed regulating component is provided between the one-way transmission component and the power generation component. This speed regulating component receives the unidirectionally transmitted mechanical energy, adjusts the rotational speed of the transmission component to a speed suitable for the rotor of the power generation component, and transmits the mechanical energy corresponding to the adjusted speed to the power generation component to drive the rotor to rotate stably. This implementation, through the reverse blocking effect of the one-way transmission component and the adaptive adjustment effect of the speed regulating component, can reduce energy loss, ensure stable operation of the power generation component, and further improve the quality and efficiency of the electrical energy conversion.
[0037] In one possible implementation, in step 102, generating an energy allocation scheme based on the energy output status and the load demand of the electrical equipment includes: acquiring the load power of the electrical equipment and real-time data during the energy conversion process, the real-time data including the real-time energy output power of the power generation component and the remaining energy data of the energy storage component; calculating the required energy quota of the electrical equipment based on the load power and the real-time data during the energy conversion process combined with a preset allocation rule; comparing the real-time energy output power with the required energy quota, and performing the following allocation action: when the real-time energy output power equals the required energy quota... When the required power supply is met, all the real-time power output is supplied to the electrical device, and the energy storage component remains in standby mode. When the real-time power output exceeds the required power supply, the required power supply is supplied to the electrical device, and the excess power value is calculated. The energy storage component is then controlled to start charging mode to receive and store the excess power value. When the real-time power output is less than the required power supply, the insufficient power value is calculated, and the energy storage component is controlled to start discharging mode to release the stored power to make up for the insufficient power value. The supplemented power is then supplied to the electrical device according to the required power supply.
[0038] In this embodiment, firstly, the load power of the electrical equipment and real-time data during the power conversion process are acquired, including the real-time power output of the power generation component and the remaining power data of the energy storage component. Secondly, based on the acquired load power and real-time data during the power conversion process, the required power quota for the electrical equipment is calculated using preset allocation rules to ensure the accuracy and adaptability of the quota calculation. Finally, the real-time power output is compared with the required power quota, and differentiated allocation actions are performed: when the real-time power output equals the required power quota, all the real-time power output is supplied to the electrical equipment, and the energy storage component remains in standby mode; when the real-time power output is greater than the required power quota, the required power quota is supplied to the electrical equipment, and the excess power value is calculated, controlling the energy storage component to start charging mode to store the excess power; when the real-time power output is less than the required power quota, the insufficient power value is calculated, controlling the energy storage component to start discharging mode to release power to make up the gap, and then supplying the supplemented power to the electrical equipment according to the required quota. By combining the charging and discharging regulation of energy storage components, the supply and demand of electricity can be effectively balanced, thereby improving energy utilization efficiency and power supply stability.
[0039] In one possible implementation, after step 103, the method further includes: collecting operating parameters corresponding to several stages of the offshore operation, and retrieving preset safety thresholds corresponding to the operating parameters of each stage; the stages include wave energy acquisition, power conversion, power distribution, and power consumption; comparing the operating parameters of each stage with the corresponding preset safety thresholds one by one; when any operating parameter is detected to exceed the corresponding preset safety threshold, triggering a fault diagnosis program, locating the specific stage and fault type of the fault through the fault diagnosis program; generating a corresponding state adjustment instruction based on the fault type, sending the state adjustment instruction to the corresponding component for execution, and issuing a warning signal to provide feedback on the fault stage and fault type.
[0040] In one possible implementation, to further ensure the stability and controllability of the entire offshore operation process, after step 103, the method further includes a full-process monitoring and fault handling step, specifically as follows: The monitoring component is activated to collect operating parameters of the energy capture component for the wave energy acquisition stage, the transmission component and power generation component for the power conversion stage, the energy management component and energy storage component for the power distribution stage, and the operating parameters of the electrical equipment and operating load for the power consumption stage; after collecting the operating parameters corresponding to several key stages of the offshore operation, the preset safety thresholds corresponding to the operating parameters of each stage are retrieved; then, the operating parameters collected for each stage are compared with the corresponding preset safety thresholds one by one; when any operating parameter is detected to exceed the corresponding preset safety threshold, a fault diagnosis program is triggered to locate the specific stage and fault type of the fault; finally, a corresponding state adjustment command is generated according to the fault type, the state adjustment command is sent to the corresponding component for execution, and an early warning signal is issued to provide real-time feedback on the fault stage and fault type. The technical objective of this implementation method is to detect and resolve potential faults in each stage in advance through full-process parameter monitoring and proactive fault handling, thereby preventing the fault from escalating and causing power outages or operational failures, and further improving the reliability and safety of the entire offshore operation system. At the same time, through early warning signal feedback, it provides maintenance personnel with accurate fault location information, reducing maintenance difficulty and costs.
[0041] The marine operation method provided in the embodiments of this application will be explained in detail below with reference to the accompanying drawings.
[0042] The maritime operation method provided in this application is applicable to a wave-powered moored airship maritime communication system. This wave-powered moored airship maritime communication system aims to address the technical pain points of limited power supply and insufficient coverage in traditional power supply modes for long-range maritime communication scenarios. By efficiently utilizing renewable wave energy, combining the high-altitude communication advantages of moored airships with intelligent energy management and control mechanisms, the system achieves green, continuous, and reliable communication coverage in long-range maritime areas. The system adopts a modular design, featuring flexible deployment, convenient operation and maintenance, and strong resistance to harsh environments. It is suitable for various maritime operation scenarios such as long-range communication relay, marine environmental monitoring, and maritime emergency communication.
[0043] This system specifically includes a wave energy generation module, a tethered airship communication platform, an energy management and storage system, and an intelligent control system.
[0044] (a) Wave Energy Generation Module The wave energy generation module is the core energy supply unit of this system. It adopts an oscillating wave energy generation device, which mainly consists of a buoy, an underwater mooring rope, a speed reducer, a spring ratchet mechanism, and a generator. Its core design logic is to capture the mechanical energy of waves through mechanical structure and convert it into electrical energy.
[0045] Figure 2 The diagram shows a schematic of the wave energy generation module provided in the embodiment of this application: The buoy at the top of the figure is the energy capture component of the wave energy. Under the action of the waves, the buoy rises and falls with the waves. The underwater mooring rope connects the buoy to the generator, reducer, and spring ratchet mechanism on the bottom of the water. The V-shaped baffle assists in the stability of the device in the seawater. The above structures together constitute an oscillating wave energy generation device.
[0046] Its operation is as follows: When there are no waves, the underwater power generation device maintains buoyancy balance to ensure stable standby; when waves rise, the buoy floats with the waves, and the underwater mooring rope pulls the spring ratchet mechanism and reducer (the two constitute the transmission component), converting the linear mechanical energy of the buoy into the rotational motion of the generator rotor, which ultimately generates electrical energy by cutting magnetic field lines; when waves fall, the underwater mooring rope loses traction and becomes slack, at which point the passive spring drives the winch to tighten the mooring rope in the opposite direction, pulling the buoy back to its original position, preparing for the next wave action. To ensure a stable energy supply, the module adopts a multi-device network design, with a rated power of 10kW and an average power generation efficiency of 30% after networking. It also has excellent resistance to harsh environments, can withstand gale-force winds of up to level 10, and is suitable for complex sea conditions in the open ocean.
[0047] (ii) Tethered airship communication platform The tethered airship communication platform is the core operational carrier of this system, undertaking long-range communication and environmental monitoring tasks. The platform uses either a hot-air airship or a helium airship, and its key performance parameters have been specifically optimized: an altitude of up to 1000m, overcoming near-sea communication obstruction limitations; an aloft time of ≥30 days, enabling long-term uninterrupted operation; and wind resistance of ≥10 levels, matching the performance of the wave energy generation module to ensure stable operation of the entire system under harsh sea conditions.
[0048] The airship carries a rich array of operational payloads, including 5G base station equipment, high-definition cameras, and environmental monitoring sensors. The 5G base station equipment provides a communication coverage radius of 100km, offering high-quality communication services to vessels, work platforms, and remote islands. The high-definition cameras and environmental monitoring sensors simultaneously perform auxiliary tasks such as visual monitoring of the marine environment and collection of meteorological parameters. Furthermore, the mooring cable connecting the airship and the anchoring platform incorporates a fiber optic composite cable. This cable serves two purposes: firstly, it transmits electrical energy, stably supplying the wave energy generation module to the airship and its payloads; secondly, it enables data communication, facilitating bidirectional transmission of data collected by the airship's payloads to the shore-based control center, ensuring real-time feedback of operational data.
[0049] (III) Energy Management and Energy Storage Systems Energy management and storage systems are key units for ensuring the balance of power supply and demand and achieving continuous operation. Their core function is to compensate for the volatility of wave energy generation and ensure a stable power supply for tethered airships and payloads.
[0050] The system uses an energy manager as its core control component, along with a 50kWh lithium iron phosphate battery pack and a DC power supply. The energy manager, as an energy management component, can monitor the real-time power generation of the wave energy generation module, the load requirements of the tethered airship and payload, and the remaining power status of the energy storage battery pack, and intelligently allocate power based on preset rules. The DC power supply is responsible for rectifying and stabilizing the power generated by the generator to ensure that the output power quality is adapted to the load requirements.
[0051] The specific control logic is as follows: The energy manager first calculates the amount of electricity required by the tethered airship based on real-time power generation and load demand; when the power generation equals the required amount, the electricity is directly supplied to the airship, and the energy storage battery pack remains in standby mode; when the power generation exceeds the required amount, the excess electricity after meeting the load demand is stored in the energy storage battery pack; when the power generation is less than the required amount, the energy storage battery pack is controlled to start the discharge mode, releasing the stored electricity to make up for the power supply gap, and then the supplemented electricity is supplied to the airship according to the required amount. Through this precise control logic, efficient energy utilization and dynamic balance between supply and demand are achieved, ensuring the continuous operation of the tethered airship.
[0052] (iv) Intelligent Control System The intelligent control system undertakes the tasks of overall system coordination scheduling, status monitoring and fault handling. It adopts an architecture that combines PLC controllers and remote monitoring systems to support automated and unmanned operation and maintenance of the system.
[0053] Among them, the PLC controller serves as the local control core, enabling coordinated control of wave energy generation devices, tethered airships, and energy storage systems, ensuring synchronized operation of each module and optimized energy scheduling; the remote monitoring system transmits system operation data (including power generation, energy storage status, load operation, environmental parameters, etc.) to the shore-based control center in real time via communication links, facilitating maintenance personnel to remotely monitor the system status.
[0054] The system also features full-process monitoring and fault handling capabilities. The specific process involves: real-time acquisition of operational parameters for key stages such as wave energy acquisition, power conversion, power distribution, and power consumption; retrieval of preset safety thresholds for each stage and comparison against them; if any parameter exceeds the safety threshold, a fault diagnosis program is immediately triggered to accurately pinpoint the specific stage and type of fault, subsequently generating corresponding status adjustment instructions and sending them to relevant components for execution, while simultaneously issuing an early warning signal to report the fault information. This function can proactively address potential faults, preventing power outages or operational failures, significantly improving system reliability, and providing maintenance personnel with accurate fault location information, reducing the difficulty and cost of offshore maintenance.
[0055] To ensure the successful deployment and stable operation of the system in offshore scenarios, this application provides a targeted offshore deployment solution: the wave energy power generation device is installed floatingly and fixed to the sea surface 5-10km from the coastline by high-strength anchor chains. This location ensures sufficient wave energy resources to meet power generation needs, covers the core communication area in the open sea, and avoids densely populated near-shore shipping areas, reducing deployment interference. The mooring platform for the moored airship can be flexibly selected according to the actual sea conditions, adapting to floating platforms (suitable for deep waters and complex terrain) or fixed platforms (suitable for shallow waters and stable terrain). The mooring platform and the wave energy power generation device are connected by submarine cables to achieve power transmission and data communication. The system adopts a modular design, and each core module can be transported to the deployment area separately for on-site assembly and debugging, significantly reducing transportation difficulty and deployment costs, while improving system scalability. The configuration can be flexibly adjusted according to the wave energy resource conditions and communication coverage requirements of different sea areas.
[0056] To further illustrate the practicality, adaptability, and operating logic of the wave energy-powered tethered airship communication system of this application, the following detailed description is provided in conjunction with specific embodiments: Example 1: Basic Configuration This embodiment provides a standard wave-powered tethered airship communication system, suitable for offshore communication relay, meeting the routine communication needs of ships, work platforms, and remote islands. The core technical parameters of this standard system are as follows: wave power generation of 10kW, tethered airship altitude of 1000m, communication coverage radius of 50km, energy storage capacity of 50kWh, wind resistance ≥10, operating temperature range of -15℃ to 60℃, and design life of 15 years. Its complete workflow consists of five stages: Phase 1: Wave Energy Generation Phase: The wave force acts on the buoy (as an energy capture component), driving the buoy to rise and fall with the waves; the buoy is pulled by the spring ratchet mechanism and the reducer (which together constitute the transmission component) through the underwater mooring rope, which converts the linear mechanical energy of the buoy into the rotational motion of the generator rotor, and finally completes the conversion of mechanical energy into electrical energy by the rotor cutting magnetic field lines, realizing the effective collection and generation of wave energy.
[0057] Phase 2: Energy Management Phase: As the core component of energy management, the energy manager monitors the output power of the wave energy generation module and the load requirements of the tethered airship and payload in real time. Following the principle of prioritizing energy supply and storing surplus energy, it prioritizes supplying electricity to the airship to ensure communication operations. When the power generation exceeds the load requirements, the excess energy is sent to the energy storage battery pack for storage, providing supplementary protection for subsequent power supply gaps.
[0058] Phase Three: Power Transmission Phase: The electrical energy generated by the wave energy generation module is first transmitted to the anchoring platform via submarine cables; then, it is transmitted a second time via the mooring cable connecting the anchoring platform and the airship. This mooring cable has a built-in optoelectronic composite cable, which can simultaneously achieve two functions: first, to stably transmit electrical energy to the airship and its onboard communication payload; and second, to complete two-way communication between the airship's data collection and the shore-based control center, ensuring real-time data feedback.
[0059] Phase 4: Communication Relay Phase: The 5G base station equipment carried by the tethered airship enters the working state. Taking advantage of the 1,000m altitude, it provides stable communication relay services for ships, work platforms and islands within the coverage area, and establishes communication links in the far sea area.
[0060] Phase 5: Status Monitoring Phase: The intelligent control system, relying on the PLC controller and remote monitoring system, initiates a full-process monitoring and fault handling procedure. The system collects operational parameters of key components such as wave energy acquisition, power conversion, power distribution, and power consumption in real time, and compares the collected data with the preset safety thresholds of each component. If any parameter is detected to exceed the threshold, the fault diagnosis procedure is immediately triggered to accurately locate the component and type of fault, generate corresponding status adjustment instructions and send them to the relevant components for execution, and simultaneously send the early warning signal back to the shore-based control center, thereby ensuring the stable operation of the system throughout the entire process.
[0061] Example 2: High Reliability Configuration This embodiment, based on the standard configuration of Embodiment 1, incorporates a multi-dimensional reliability enhancement design to address the stringent requirements of harsh marine environments (such as strong winds and waves, high salt spray, and complex sea conditions). This further improves the system's operational stability and continuity under extreme conditions, making it suitable for critical communication tasks in harsh, open-ocean environments. Details are as follows: 1. Optimization of bidirectional drive for wave energy generation device: Based on the unidirectional power generation (power generation only when the wave rises) in Example 1, the motion adaptation logic of the transmission component is optimized. By improving the transmission adaptation structure of the spring ratchet mechanism, the generator can be driven in both the rising and falling phases of the wave. This not only improves the utilization rate of wave energy, but also significantly improves the power generation efficiency and ensures the stability of energy supply.
[0062] 2. Dual-battery redundancy configuration of energy storage system: The single lithium iron phosphate battery pack in Example 1 is optimized into a dual-battery redundancy configuration with independent operation. The two battery packs are monitored in parallel and powered independently. When one battery pack fails (such as abnormal power or circuit failure), the energy manager can automatically identify the fault status and switch to the other battery pack for power supply, thus completely avoiding the risk of system downtime caused by energy storage interruption.
[0063] 3. Dual-link backup design for communication system: Based on the single communication link in Example 1, a backup communication link is added. The main link (such as the built-in optical fiber composite cable link) and the backup link (such as the emergency wireless communication link) are monitored in real time and serve as backups for each other. When the main communication link is interrupted due to sea interference, cable failure, etc., the system can automatically switch over in milliseconds to ensure that the communication relay service is not interrupted.
[0064] 4. Control system hot standby redundancy scheme: The PLC controller adopts a dual-unit hot standby design with the main control unit and the standby control unit operating data in real time. When the main control unit fails, the standby unit can immediately and seamlessly take over the control function. The entire process regulation can be maintained without restarting the system, ensuring that core control functions such as energy scheduling, status monitoring, and fault handling are not interrupted.
[0065] To further adapt to the complex marine environment and ensure the long-term safe operation of the system, this embodiment also sets up a multi-dimensional safety protection mechanism scheme, covering all scenarios including electrical, mechanical, communication, and environmental aspects: 1. Electrical Safety: The system is equipped with an isolation transformer and a leakage protection device. Through hardware protection and intelligent monitoring, it ensures that the system insulation resistance is ≥10MΩ and the grounding resistance is ≤0.1Ω, effectively avoiding the risk of electrical faults such as short circuits and leakage. 2. Mechanical safety: An overload protection module is added to the transmission components and motor of the wave energy power generation device. When the motor speed is detected to exceed the rated value, the system automatically triggers a shutdown command to prevent mechanical failures such as wear of transmission components and burnout of motor caused by overload operation. 3. Communication Security: The system adopts a national-level encrypted communication protocol to encrypt all data transmitted between the airship and the shore-based control center and between various modules. At the same time, an access permission verification mechanism is set up to effectively prevent data leakage, tampering and illegal intrusion. 4. Environmental safety: The main structure and core components of all equipment deployed at sea are made of special alloy materials that are resistant to salt spray and corrosion, and the surface is coated with an anti-corrosion coating, which can adapt to the high humidity and high salt spray marine environment for a long time and extend the service life of the equipment.
[0066] In summary, the method provided in this application is the first to combine wave energy power generation technology with a moored airship communication system, achieving green, sustainable, and clean energy self-sufficiency in offshore communication scenarios and overcoming the limitations of traditional fuel-powered electricity. It proposes a multi-energy complementary scheme of "wave energy power generation + energy storage + moored airship," solving the power supply bottleneck for maritime communication through the coordinated regulation of the energy management system. An intelligent energy management and full-process monitoring system is designed to achieve coordinated and optimized control of wave energy power generation, energy storage units, and airship loads, while improving system reliability through proactive fault handling. A modular and scalable architecture is adopted, allowing for flexible configuration based on wave energy resources and communication needs in different sea areas, reducing deployment costs. A safety system covering electrical, mechanical, communication, and environmental aspects is established to ensure reliable operation of the system in harsh marine environments.
[0067] In summary, this application provides a method for offshore operations that collects the mechanical energy of ocean waves and converts it into electrical energy.
