On October 10, 2025, Sinopec (600028) announced the granting of its utility model patent for a "Multi-stage Buffering Anti-collision Fender for LNG Terminals" (Patent No.: CN202422819097.0). This patent addresses the insufficient cushioning capacity of traditional two-drum, one-plate fenders during berthing of LNG vessels. The patent innovatively utilizes an expanded nearshore structure and a curved anti-collision steel plate + rubber composite layer. This multi-stage cushioning mechanism improves impact absorption efficiency by over 30%. Its core advantages include:
Breakthrough in impact resistance: Through optimized internal gas distribution and structural mechanics, it can withstand the instantaneous impact of a 200,000-ton LNG carrier berthing at 8 knots, reducing structural stress on the terminal by 45% compared to traditional fenders. Extreme Environment Adaptability: Utilizing a special rubber material that is resistant to low temperatures (-46°C) and corrosion-resistant, it is suitable for harsh environments such as polar LNG receiving stations.
Reserved Interface for Intelligent Monitoring: The patent reserves a mounting position for a pressure sensor, enabling integration of an IoT module for real-time air pressure monitoring and fault warnings.
This technology has entered the pilot phase and is planned for demonstration applications in national-level LNG hub ports such as Zhangzhou, Fujian, and Rudong, Jiangsu. Large-scale deployment is expected by 2026. This breakthrough will accelerate the domestic substitution of high-end port equipment in my country.
