[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be combined with the attached Figures 1 to 4 The technical solutions of the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0020] Example 1: Figure 1As shown, an integrated comprehensive measurement system for floating installation of an offshore platform of the present invention comprises at least five subsystems, namely, a marine environment monitoring system 2, a hull motion monitoring system 3, a fender load monitoring system 4, a DSU module separation monitoring system 5, and an all-round video monitoring system 6, and an integrated comprehensive monitoring platform 1 for centralized management of each subsystem. The integrated measurement system of the present invention can monitor various information such as ocean wind, wave, current and tide level, platform position, hull six-degree-of-freedom motion, fender load, DSU module separation gap, and real-time dynamic video of the ship-entering process in real time, accurately and comprehensively during the floating installation process. Through the integrated comprehensive monitoring platform, each subsystem is centrally managed and multi-data fusion is processed, so that the integration and fusion of the entire system are higher, and the measurement information is integrated, synchronous, and real-time, so as to ensure the safe and reliable operation of the system during the floating installation monitoring process, greatly reduce the risk of floating installation operations, and effectively guarantee the successful installation of the offshore platform.

[0021] The marine environment monitoring system 2 includes a wind speed and direction instrument 7, an X-band radar wave measurement system 8, a Doppler current meter 9 and a water pressure tide gauge 10. The wind speed and direction instrument 7 includes a three-cup anemometer and a wind vane installed on a small cross arm. The wind speed is measured by the three-cup anemometer, and an AC sine wave voltage with a frequency proportional to the wind speed is generated by the rotation of the cup wheel, and the wind speed accuracy is ±0.5m / s; the wind direction is measured by the wind vane, and the wind direction signal is transmitted through a 10kΩ potentiometer at the blade position. When a precise excitation voltage is applied, the output voltage is proportional to the wind direction, and the wind direction accuracy is ±5°. The wind speed and direction instrument 7 monitors and collects data on the wind speed and direction.

[0022] The X-band radar wave measurement system 8, wave buoy and Doppler current meter 9 cooperate to monitor and collect the ocean dynamic environment information of waves and currents within the range of several nautical miles. The waves are monitored in real time by the X-band radar wave measurement system 8, which consists of the X-band radar wave measurement system 8, radar signal acquisition controller, wave analysis and display terminal and data transmission radio station. The resolution of detecting wave height is 0.1m, the direction resolution is 1°, the time resolution is 0.1s, the wave height measurement accuracy is ±0.2m, the period accuracy is ±0.5s, and the direction accuracy is ±5°, which meets the requirements of small wave measurement in the construction area. The real-time measurement data of the X-band radar wave measurement system 8 includes the maximum wave height, effective wave height, average zero-crossing period, wave direction, surge height, surge direction, etc. The X-band radar wave measurement system 8 uses the data of the standard ship X-band (3cm) radar as the signal input. In addition to wave parameters such as wave height, direction, and period, a complete three-dimensional spectrum of waves can also be obtained. The ocean current is monitored by a Doppler current meter 9, which provides real-time velocity and direction information. The resolution of velocity measurement is 0.01 m / s, the resolution of direction is 1°, the velocity accuracy is ±0.1 m / s, and the direction accuracy is ±5°. The velocity measurement meets the measurement requirements.

[0023] The hydraulic tide gauge 10 is used to collect and record tidal data for long-term monitoring of unmanned locations. The principle is to place the hydraulic tide gauge 10 in a fixed position underwater, and calculate the fluctuation of the sea surface by detecting the pressure change of the seawater. The hydraulic tide gauge 10 is installed in the round pipe of the on-site conductor rack to provide real-time tide information in the operating sea area, and the influence of waves needs to be eliminated. The resolution of tide level measurement reaches centimeter level, and the actual resolution reaches ±0.01m. Tide level measurement meets the measurement requirements. The measurement data is sent by wireless transmission, and the transmission distance can reach 1km, which can be displayed in real time on the comprehensive monitoring platform.

[0024] The marine environment monitoring system 2 of this embodiment can monitor and collect data information on marine environmental conditions such as wind, waves, currents and tide levels in real time to ensure that the command personnel can obtain real-time on-site environmental information in a timely and efficient manner, thereby correctly judging the climate window period during the floating installation process and guiding on-site operations to be carried out safely and effectively.

[0025] like Figure 1 As shown, the hull motion monitoring system 3 collects the position, bow direction and six-degree-of-freedom motion data information of the platform in real time. The hull motion monitoring system 3 monitors the real-time motion of the barge and the upper module during the floating installation process, including the cruising and anchoring stages, entering the ship, docking, and leaving the ship, specifically including: the position and bow direction of the platform; the six-degree-of-freedom motion of the barge, the upper module and the center of gravity of the system (referring to the overall center of gravity of the ship and the module), including longitudinal swing, transverse swing, vertical swing, pitch, roll, and bow swing; the speed and acceleration of the main leg inversion tip of the module in the early stage of entering the ship and docking in three directions, as well as the distance between the tip and the top of the pile leg docking buffer device LMU.

[0026] The hull motion monitoring system 3 includes a combined motion monitoring system that combines a GPS positioning system 11 and an INS inertial navigation system 12. The GPS positioning system 11 includes a dual-frequency GPS system and an RTK differential positioning system. The dual-frequency GPS mobile station is longitudinally installed on the barge, and the RTK differential positioning system is installed on the conductor frame. Based on the dual-frequency GPS mobile station, the angle of the barge relative to the geographic north can be calculated. The GPS positioning system 11 measures the position of the platform through the RTK differential method. The GPS system has high measurement accuracy, but it has the disadvantages of being susceptible to interference, discontinuous output, and incomplete output information. The INS inertial navigation system 12 is composed of a gyroscope and an accelerometer 13. Unlike the measurement of the GPS positioning system 11, the INS inertial navigation system 12 has the advantages of anti-interference, no reliance on external information, and can work all day and night. It can autonomously provide six-degree-of-freedom motion parameters and monitor the linear displacement and inclination of the barge with high reliability. The accelerometer 13 is used to monitor and record the acceleration data of the specific position of the platform in the longitudinal, lateral, and vertical directions. Therefore, the use of the GPS positioning system 11 and the INS inertial navigation system 12 in combination can combine the advantages of the two measurement methods, enhance the reliability, availability, environmental adaptability and dynamics of the system, and achieve reliable centimeter-level position accuracy and attitude accuracy. The specific accuracy is: absolute horizontal position accuracy of ±0.02m, absolute vertical position accuracy of ±0.05m, absolute angular motion accuracy of ±0.02°, and absolute linear velocity accuracy of ±0.1m / s.

[0027] like Figure 1As shown, the fender load monitoring system 4 collects the collision data information between the fender and the jacket pile leg in real time. During the floating installation process, due to the small distance between the barge fender and the jacket pile leg, collision is basically unavoidable, which may cause damage to the jacket platform pile leg and the barge fender. Therefore, it is very necessary to monitor the impact force between the barge fender and the jacket pile leg in real time. During the floating installation process, due to the large collision load between the barge fender and the jacket, the random collision point and the long fender, conventional pressure sensors, infrared detection technology, etc. are not applicable. The fender load monitoring system 4 of the embodiment of the present invention includes an optical fiber strain gauge 14 and an optical fiber demodulator 15. The optical fiber strain gauge 14 is arranged on the barge fender bracket along the length direction. The optical fiber strain gauge 14 is electrically connected to the optical fiber demodulator 15 and monitors the impact force between the fender and the jacket pile leg in real time. The installation position of the optical fiber strain gauge comprehensively considers the relationship between the density of measuring points and the equipment capacity, and arranges correspondingly more measuring points in the area with large strain changes calculated theoretically. The sensor measurement data is demodulated by the optical fiber demodulator 15 and transmitted to the integrated comprehensive monitoring platform 1 by the wireless transmission device. The optical fiber strain gauge adopts the optical fiber strain measurement method for measurement. Multiple sensors can be connected in series using the same optical fiber. The sensor is small in size and easy to install, which reduces the measurement channel requirements of the demodulator. The optical fiber has the characteristics of anti-interference and low attenuation, which can meet the requirements of long-distance transmission.

[0028] like Figure 1 As shown, the DSU module separation monitoring system 5 measures the separation gap from the sensor to the lower surface of the support platform in real time, and determines whether the requirements for safe ship withdrawal are met. The DSU module separation monitoring system 5 includes four laser ranging sensors 16 installed vertically along the main deck. The laser ranging sensor 16 measures the distance between the sensor and the lower surface of the support platform, thereby measuring the separation gap distance of the lower surface of the upper module of the support platform. The DSU module separation monitoring system 5 can solve the shortcomings of the conventional method of using visual inspection and experience to judge the safe distance, and ensure the safety and reliability of ship withdrawal. The laser ranging sensor has a range of 0.2~70m, a resolution of 1mm, and a measurement accuracy of 3mm. It uses a red laser and an adjustable mounting bracket, which can quickly and conveniently complete calibration and installation. The DSU module separation monitoring system 5 performs algorithm conversion on the collected data through coordinate setting to obtain the real-time separation gap of the DSU module at each measuring point on the hull. According to the comparison between the real-time monitored separation gap and the critical gap for safe exit, it is judged whether the safe exit requirements are met and displayed in real time on the integrated comprehensive monitoring platform 1. When the measurement point status shows red, the separation gap has not reached the safe distance, and when it shows green, the separation gap has reached the safe distance. When all measurement points show green status and meet the safe distance, the barge can exit safely. The DSU module separation monitoring system 5 adopts a redundant design. If any one of the four laser ranging sensors fails, it can still work normally based on the remaining three laser ranging sensors.

[0029] like Figure 1 As shown, the omnidirectional video monitoring system 6 visually monitors the entire shipboard installation process through a 360° rotatable video monitoring system. The omnidirectional video monitoring system 6 includes six cameras 17 correspondingly installed around the LMU docking unit and one camera 17 correspondingly installed on both sides of the stern to monitor the barge's shipboard process; the camera 17 is a 360° rotatable camera, using a high-definition camera, and a high-resolution imaging unit to ensure a clear image. The camera uses infrared weak light assistance so that it can also monitor in dim light. The camera's shooting direction can be remotely controlled by the integrated comprehensive monitoring platform 1, and multi-camera videos can be displayed on the screen of the integrated comprehensive monitoring platform 1 at the same time, and a single-camera video can be zoomed in or displayed in full screen. The omnidirectional video monitoring system has two main functions: during the shipboard process, the high-definition camera is responsible for capturing the relative position of the bow and the conductor frame to provide a reference for on-site command, and at the same time monitors the deformation of the rubber cushions on both sides of the bow, estimates the force on them and compares them with the fender load monitoring system 4; during the docking stage of the module and the conductor frame, the camera is responsible for monitoring the movement of the plug tip and DSU and their relative position.

[0030] like Figure 1 As shown, the integrated comprehensive monitoring platform 1 integrates the monitoring of each subsystem, and is centrally installed in a container-type integrated control room and arranged on the deck of the barge; the integrated comprehensive monitoring platform 1 has centralized data collection and data connection functions, and uses a variety of remote signal transmission technologies and data sharing technologies to collect multi-channel monitoring data, and transmits it wirelessly from the integrated comprehensive monitoring platform 1 to the operating position of the operator to issue an execution command. Each subsystem collects all-round monitoring of the floating installation process and module separation data through sensors and data transmission and transmits it to the integrated comprehensive monitoring platform 1, which coordinates and manages the operation window decision-making and the on-site surveying and mapping plan to successfully guide the centimeter-level ship entry to complete the offshore platform installation. The integrated comprehensive monitoring platform 1 can realize the centralized management of multiple sensors, the fusion processing of multiple collected data, and the centralized visual management of multiple subsystems. The integrated comprehensive monitoring platform 1 and each subsystem are in a tree structure, which is linked through a communication system, and the distributed subsystem measurement equipment is synchronously controlled, data is collected and returned, and integrated processing and display are performed through the central processing unit; it has centralized data collection and good data connection functions, uses a variety of remote signal transmission technologies and data sharing technologies to collect multi-channel monitoring data, and transmits it from the integrated monitoring platform to the location of the operators by wireless means, realizing the integration, intelligence and synchronization of floating installation monitoring.

[0031] Example 2: Based on Example 1, Figure 2~3As shown, the integrated comprehensive monitoring platform 1 also includes an alarm control host 18 arranged in the control room, and a control keyboard 19, an audible and visual alarm 20, an alarm recorder 21 and a linkage controller 22 respectively electrically connected to the alarm control host 18, and the alarm control host 18 is respectively electrically connected to the detectors 24 and the corresponding address coding modules 23 correspondingly arranged at each operating position of the barge, and each address coding module 23 is also correspondingly connected to an emergency alarm device 25. The present invention also includes a barge environment detection system 26, and the barge environment detection system 26 includes an intelligent gateway 27, and the detector 24 includes but is not limited to a temperature and humidity sensor 28, a water leakage sensor 29, a wind speed sensor 30 and a gas detector 31 connected to the intelligent gateway 27; the intelligent gateway 27 is respectively connected to the air conditioning system 32, the fan pump 33, the lighting system 34 and the security system 35. The detectors 24 at various operating positions of the barge can collect wind speed, temperature, humidity, water leakage, fire and other conditions accordingly, and mark the specific monitoring position through the address coding module 23 to facilitate the determination of the specific location where the water leakage, fire and other conditions occur, and the emergency alarm device 25 at the corresponding position can sound an alarm, and respond by controlling the air-conditioning system 32, fan water pump 33, lighting system 34 and security system 35 according to the specific type of disaster.

[0032] Example 3: Based on Example 1 and Example 2, Figure 4 As shown, the security system 35 includes an automatic fire alarm system 36 and a fire linkage control system 37. The automatic fire alarm system 36 includes a fire alarm controller 38 and a manual fire alarm button 39 connected to the fire alarm controller 38, a fire power supply 40, an audible and visual alarm 20, and a transmission device 41; the fire linkage control system 37 includes a fire linkage controller 42 electrically connected to the fire alarm controller 38, and the fire linkage controller 42 is respectively connected to the gas fire extinguishing system 43, the fire curtain system 44, the smoke exhaust system 45, and the fire hydrant pump 46. When a fire occurs at a corresponding position of the barge, the fire can be detected manually or by the detector 24, and a fire alarm can be issued. The gas fire extinguishing system 43, the fire curtain system 44, the smoke exhaust system 45, and the fire hydrant pump 46 cooperate to achieve timely elimination of the fire and prevent the fire from spreading.

[0033] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
