The offshore oil platform needs to establish a high reliability security system that integrates "high-altitude protection gas monitoring sea area warning". The core configuration is as follows:
I. Personnel safety protection system
High altitude fall protection system
Vertical lifeline system: including constant force energy buffer and self-locking device, locking the steel cable within 0.3 seconds when falling, supporting tower/ladder installation;
Sealed differential: resistant to salt spray corrosion, automatically retracts safety rope, and cooperates with V-FIT full body safety belt to achieve free movement and fall prevention;
Anti slip walkway+guardrail: Anti corrosion guardrails are installed at the edge of the platform, and anti slip grilles are laid in key passages.
II. Environmental and Gas Monitoring Network
Explosion proof gas detector
Fixed detector:
DF-8500 type: IP66/IP67 protection, wide temperature operation from -40 ℃ to+70 ℃, anti electromagnetic interference, supports multi gas detection such as methane/hydrogen sulfide;
Ultima X5000 model: dual probe design, integrated electrochemical/infrared/catalytic combustion technology, automatic calibration and ATEX/IECEx explosion-proof certification;
Portable spectrometer: Raman technology detects Pic level explosive or biochemical residue within 30 seconds.
Oil spill monitoring system
Non contact sensors scan the sea surface in real-time, accurately identify oil films, and trigger alarms to reduce the risk of marine pollution.
III. Maritime and perimeter security system
（1） Stereoscopic monitoring layer
4-kilometer observation pan tilt camera:
Waterproof and salt spray resistant design, thermal imaging penetrates through rain and fog, supports automatic ship tracking and illegal intrusion recognition;
Millimeter wave perimeter radar:
Haojing Hjot-LD125 model: Multi target tracking within a radius of 125 meters (accuracy of 0.5 meters), with a bad weather false alarm rate of less than 1%.
（2） Intelligent Warning Center
Radar AIS optoelectronic fusion system:
Integrating radar scanning, ship AIS signals, and optical images, automatically predicting target trajectories and linking sound and light alarms;
Drone countermeasure module:
Directed radio frequency interference with a radius of 3 kilometers to block illegal drones from approaching the platform.
IV. Special protection for key facilities
Technical indicators for risk point protection plan
Helicopter deck anti slip coating+navigation indicator light wind resistance level ≥ 12
Explosion proof wall (0.25mm lead plate) in oil and gas processing area+high temperature detector shielding radiation+500 ℃ over temperature alarm
Inert gas fire extinguishing system for distribution cabin+intelligent temperature control distribution cabinet temperature fluctuation ± 0.5 ℃ linkage response
Efficiency optimization:
The centralized control platform integrates gas/video/radar data, with an accident response delay of less than 5 seconds.
V. Emergency and rescue configuration
Negative pressure decontamination chamber:
Biochemical threat isolation capability, 0.3 μ m particle filtration efficiency>99.97%;
Explosion proof rescue equipment:
Hydraulic dismantling tool set+anti-static protective clothing, meeting Ex explosion-proof standards;
Emergency communication network:
Dual satellite links ensure uninterrupted command for 72 hours.
Technology Trend:
The Mesian high-altitude protection system covers 80% of the world's offshore platforms, and millimeter wave radar and AI trajectory prediction technology have become the new industry standards.
