Description

Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a safety monitoring system for a floating oil storage and offloading vessel. Background Technology

[0002] Floating production storage and offloading (FPSO) units, which perform preliminary processing and storage of crude oil, are known as "offshore oil factories." The side loading and unloading stations of FPSOs are critical operational areas for the transfer of media such as crude oil, fresh water, and fuel oil. These areas are classified as explosive hazardous zones with harsh environments and a high concentration of risks.

[0003] Existing technologies at shipboard loading / unloading stations may present risks such as personnel operation risks, leakage and fire / explosion risks, and ship dynamic risks. Current monitoring methods are outdated and heavily reliant on manual labor, making it difficult to achieve safe management of personnel areas. Personnel operating heavy hoses and booms in narrow, slippery deck areas may slip, fall, or be struck. Flanges and quick-connect fittings in oil storage and offloading units may leak media during operation due to vibration, corrosion, or misoperation, creating flammable gas clouds in the work area, which can easily ignite fires or even explosions upon contact with an ignition source. Both oil storage and offloading units and supply ships are located at sea, resulting in complex relative movements due to wind, waves, and currents. Consequently, connecting hoses may become excessively tight and break, or accidentally detach from the system, causing serious economic losses and environmental pollution. Current monitoring methods mainly consist of traditional closed-circuit television (CCTV) and periodic personnel patrols. CCTV systems require continuous manual monitoring, while manual patrols have blind spots, detection delays, and expose personnel to hazardous environments. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of existing monitoring systems that rely on manual labor, lack proactive perception, and cannot respond in a timely manner, thereby providing a safety monitoring system for offshore floating oil storage and offloading vessels.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A safety monitoring system for a floating oil storage and offloading (Floating Storage and Offloading) vessel includes an overall vessel, an operating platform, and a control room. Both the operating platform and the control room are located on the overall vessel. The operating platform is positioned near the side of the overall vessel. A crane structure is also located on the overall vessel near the operating platform. A supply vessel is positioned outside the overall vessel near the operating platform, connected to the overall vessel by a flexible hose. The area containing the operating platform, crane structure, and supply vessel is the working area, while the area containing the control room is the safety area. The system also includes a visual sensing module, a computing control module, and a wiring module. The visual sensing module and the computing control module are connected via the wiring module, which also enables signal transmission. The visual sensing module is located in the working area, while the computing control module is located in the safety area and within the control room. The visual sensing module includes a first sensing unit and a second sensing unit communicatively connected to the computing control module. The first sensing unit is fixed to the top of the operating platform via a gimbal bracket, and the second sensing unit is fixed to the side of the overall vessel via an explosion-proof bracket, corresponding to the water area between the supply vessel and the overall vessel.

[0006] By adopting the above technical solutions, this monitoring system transforms the original "passive response" into "active early warning" through visual sensing modules, computing control modules, and circuit modules. It identifies risks before or in the early stages of an accident, achieving ultra-early intervention, which is in line with the advanced risk-based safety concept advocated by classification societies. It also shifts the focus from "human defense" to "technology defense": greatly reducing reliance on manual monitoring, avoiding safety accidents caused by human error, freeing personnel from high-risk environments, and effectively improving personnel safety.

[0007] Furthermore, the first sensing unit includes a high-definition visible light camera and an infrared thermal imaging camera arranged coaxially, both of which are positioned overlooking the work area.

[0008] By adopting the above technical solutions, both high-definition visible light cameras and infrared thermal imaging cameras can monitor the entire manifold, flange, quick coupling, and personnel operation area. The high-definition visible light camera is mainly used to collect video streams of the operation scene and work with the computing control module to perform behavior recognition and status monitoring. The infrared thermal imaging camera is mainly used to identify low temperature anomalies caused by medium leakage and vaporization, or high temperature hotspots caused by friction / electrical short circuits.

[0009] Furthermore, at least one second sensing unit is provided. When multiple second sensing units are provided, the second sensing units are evenly distributed on the side of the ship as a whole, and all the second sensing units are set towards the water area between the supply ship and the ship as a whole.

[0010] By adopting the above technical solution, multiple second sensing units are set up to facilitate intelligent sensing of the distance between the two ships. The data obtained by the multiple second sensing units can be compared after being sent to the computing and control module. The exact position can be obtained after comparison, and the dynamic relative position of the two ships can be monitored to avoid the hose breaking or accidentally falling off due to the influence of wind, waves and currents.

[0011] Furthermore, the second sensing unit includes a laser rangefinder and a wide-angle camera arranged side by side on the explosion-proof bracket. The laser rangefinder measures the relative distance between the ship as a whole and the supply ship, and the wide-angle camera is positioned towards the hose and the boom structure.

[0012] By adopting the above technical solutions, the laser rangefinder is used to measure the relative distance between the two ships in real time with precision; the wide-angle camera is used to monitor the overall shape of the hose or boom structure and the dynamic relative position of the two ships.

[0013] Furthermore, the computing control module includes a relay output board, a power supply module, a communication module, a forced cooling module, and a computing module. The power supply module provides centralized power to the relay output board, the communication module, the forced cooling module, and the computing module. The communication module communicates with the first sensing unit and the second sensing unit and the computing module, and realizes data exchange between the first sensing unit, the second sensing unit, and the computing module. The forced cooling module dissipates heat from the computing module, and the relay output board receives instructions from the computing module.

[0014] By adopting the above technical solution, the computing module is equipped with a high-performance AI inference computing card, which is responsible for running the trained deep learning algorithm model and processing multi-source data transmitted from the vision sensing module. The relay output board, as the core control hardware, receives the signals from the computing module and outputs switching signals through the hard contacts (dry contact signals) of the physical relays. The power supply module and communication module provide centralized power supply and data exchange for the corresponding modules and interfaces. The forced cooling module dissipates heat from the computing module and other heat-generating components to ensure stable operation of the equipment.

[0015] Furthermore, the line module is an optical cable structure, and each line module is equipped with an explosion-proof sealing structure when it passes through the boundary of the working area.

[0016] By adopting the above technical solutions, the risk identification and safety execution systems are directly linked through reliable hardware links and line modules, forming an automated safety closed loop and truly realizing the inherent safety of the system; the explosion-proof sealing structure prevents flammable media from entering the safety zone, ensuring the safety of the safety zone and also ensuring the standardization of functional division.

[0017] Furthermore, it also includes an emergency shutdown module, which includes a manual control unit and an automatic control unit, and the automatic control unit is communicatively connected to the computing control module.

[0018] By adopting the above technical solutions, users can freely choose between manual control units and automatic control units. Manual control serves as a substitute for automatic control, ensuring operational safety and enhancing proactiveness in the early stages of an accident.

[0019] In summary, the technical solution of this utility model has the following advantages: 1. The safety monitoring system for offshore floating oil storage and offloading vessels provided by this utility model transforms the original "passive response" into "active early warning" through a visual sensing module, a computing control module, and a circuit module. It identifies risks before or in the early stages of an accident, achieving ultra-early intervention, which is in line with the advanced risk-based safety concept advocated by classification societies.

[0020] 2.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

Both the operating platform 02 and the control room 03 are located on the overall vessel 01. The operating platform 02 is located on the side of the overall vessel 01. A crane structure 04 is also located on the overall vessel 01 near the operating platform 02. A supply vessel 05 is located outside the overall vessel 01 near the operating platform 02. A flexible hose 06 connects the supply vessel 05 to the overall vessel 01. The area where the operating platform 02, the crane structure 04, and the supply vessel 05 are located is the work area 07, and the area where the control room 03 is located is the safety area 08.

[0027] It also includes a visual sensing module 1, a computing control module 2, and a wiring module 3. The visual sensing module 1 and the computing control module 2 are connected through the wiring module 3 and signal transmission is achieved through the wiring module 3.

The visual sensing module 1 includes a first sensing unit 11 and a second sensing unit 12 that are communicatively connected to the computing control module 2. The first sensing unit 11 is fixed to the top of the operating platform 02 by a gimbal bracket 011, and the second sensing unit 12 is fixed to the side of the ship as a whole 01 by an explosion-proof bracket 012 and is set in the water area between the supply ship 05 and the ship as a whole 01.

[0028] Line module 3 is an optical fiber structure, and each time line module 3 crosses the boundary of work area 07, it is equipped with an explosion-proof sealing structure 31.

Both the high-definition visible light camera 111 and the infrared thermal imaging camera 112 can monitor the entire manifold, flange, quick connector, and personnel operation area. The high-definition visible light camera 111 is mainly used to collect video streams of the work scene, working with the computing control module 2 for behavior recognition and status monitoring. The infrared thermal imaging camera 112 is mainly used to identify abnormal low temperatures caused by medium leakage and vaporization, or high-temperature hotspots caused by friction / electrical short circuits. The high-definition visible light camera 111 can collect personnel behavior data and transmit it to the computing control module 2 for recognition, such as collecting data on personnel falls, personnel wearing safety equipment, and personnel entering dangerous areas. The combination of the high-definition visible light camera 111 and the infrared thermal imaging camera 112 can collect data on medium leakage (visible light pattern + thermal imaging temperature difference), smoke, and open flames.

[0030] At least one second sensing unit 12 is provided. When multiple second sensing units 12 are provided, they are evenly distributed on the side of the vessel 01 and all facing the water area between the supply vessel 05 and the vessel 01.

[0031] The second sensing unit 12 includes a laser rangefinder 121 and a wide-angle camera 122 mounted side-by-side on the explosion-proof bracket 012. The laser rangefinder 121 measures the relative distance between the overall vessel 01 and the supply vessel 05, while the wide-angle camera 122 is positioned towards the flexible hose 06 and the boom structure 04. The laser rangefinder 121 is used to accurately measure the relative distance between the two vessels in real time; the wide-angle camera 122 is used to monitor the overall shape of the flexible hose 06 or the boom structure 04 and the dynamic relative positions of the two vessels.

The power supply module 22 provides centralized power to the relay output board 21, communication module 23, forced cooling module 24, and computing module 25. The communication module 23 connects the first sensing unit 11 and the second sensing unit 12 to the computing module 25 and enables data exchange between them. The power supply module 22 and communication module 23 provide centralized power supply and data exchange for their respective modules and interfaces. The forced cooling module 24 cools the computing module 25 to ensure stable operation. The computing module 25 is equipped with a high-performance AI inference computing card, responsible for running trained deep learning algorithm models and processing multi-source data transmitted from the visual sensing module 1. The relay output board 21 receives instructions from the computing module 25.

[0033] It also includes an emergency shutdown module 4, which comprises a manual control unit 41 and an automatic control unit 42. The automatic control unit 42 is communicatively connected to the computational control module 2. The manual control unit 41 and the automatic control unit 42 are freely selectable by the user. Manual control serves as a substitute for automatic control, ensuring operational safety and enhancing proactiveness in the early stages of an accident.

[0034] Data collected by the first sensing unit 11 and the second sensing unit 12 is transmitted to the communication module 23, where it is then transferred to the computing module 25. The computing module 25 is equipped with relevant algorithms and a corresponding database. For example, it can extract features from the collected images, classify and summarize them, and identify whether personnel have fallen, are wearing safety equipment, or have entered dangerous areas, recording and storing these information for later verification. It can also be equipped with a neural network and deep learning controller to predict the distance between the floating body and the supply ship 05 to avoid collisions or to determine the shape of the hose 06 to avoid the risk of overstretching.
