Private network enhances hazard management at oil reserve base

Caltta Technologies, a provider of mission-critical communication solutions, has delivered a customised private wireless communication system for the Lanzhou Petrochemical National Oil Reserve Base in China, significantly improving the facility’s hazard management and emergency response capabilities.

As part of China’s Phase II National Oil Reserve initiative, the Lanzhou Petrochemical QCGC project is a key component of the country’s strategic energy infrastructure. The site comprises 30 floating-roof storage tanks with a total capacity of 3 million m³, supported by auxiliary systems for instrumentation, communications, water supply, drainage and fire protection.

With the increasing operational lifespan of the facility and evolving regulatory standards for hazardous chemicals and major hazard sources, the demand for a safer and more reliable communication system has grown. Caltta’s private network solutions have already supported major petrochemical players in China — delivering secure, efficient communications across both large-scale projects and daily operations — and so the company was confident in collaborating with partner Shandong Jiangke IT to provide a tailored solution designed to meet the facility’s heightened safety and operational requirements.

Caltta deployed a new digital two-way radio system using the facility’s existing communication tower infrastructure. This ensures uninterrupted private network signal coverage across the entire site — with no blind spots — enabling staff to communicate in real time from any location, improving situational awareness and emergency responsiveness.

The solution includes professional-grade explosion-proof radios (certified to Ex ib IIB T4 Gb/Ex ib IIIC T130°C Db standards), capable of operating safely and stably in high-risk petrochemical zones. These radios are designed to ensure secure communications for frontline personnel under challenging conditions.

By integrating the wireless communication system with a soft-switch platform, Caltta enabled seamless interoperability between radios, dispatch consoles and office PBX systems. This unified command and control structure facilitates efficient coordination between field operations and management teams.

With the deployment of a wide-coverage, fast-response and agile dispatch private network, the Lanzhou oil reserve base has significantly strengthened its communication infrastructure — providing a solid foundation for risk mitigation, hazard monitoring and emergency management.
