Safe is the starting point every day
As of April 24, the Dongying Crude Oil Storage Base, which has been in operation since 1986, celebrated a milestone: 10,000 days of safe operations. In a message titled "Secure Voices," Master Li Jiankun, who had just retired, shared a simple but powerful reminder with his colleagues: "If you are safe today, it doesn’t mean you will be safe tomorrow."
These 13 words reflect the deep sense of responsibility among oil depot workers and reveal the secret to long-term safety in the facility. With over 12,810 risk points monitored across the site, every detail is critical.
Safety officer Zhao Zhengang arrives half an hour before his shift begins. Routine inspections have become second nature to him after years of dedicated service. He checks nearly 300 fire extinguishers, 26 fire boxes, 21 fire cannons, and almost 100 fire hydrants—each part of a vast 330,000-square-meter area. “One small mistake could lead to a major accident,†he says. That mindset keeps him focused and vigilant.
The Dongying Crude Oil Storage Base is the operational heart of Shengli Oilfield, featuring 14 large storage tanks, 350 sets of equipment, and 12,810 risk monitoring points. To manage this complexity, the base has implemented a comprehensive safety network that covers all personnel, areas, processes, and times. Risk points are categorized into A, B, and C based on severity, and each is monitored through triple coverage by on-duty workers, shift supervisors, and senior staff.
Every hour, employees check their assigned safety points, while shift supervisors inspect every two hours, and on-duty cadres do so every four hours. For key facilities like the oil storage tanks, the “triple hard management†approach ensures that at least three tanks are checked daily by measurement workers, and critical areas are inspected multiple times per day by branch members.
Each month, eight technical officers conduct detailed checks of the tanks, and six team members evaluate the results. Over the course of a year, these inspections amount to a 25,000-mile journey—equivalent to the Long March—and the combined height of the tanks inspected by four teams would equal climbing Mount Everest eight times.
During a night inspection, Gang Ai, a flow meter operator, noticed unusual noise from the bearing of Pump No. 5. Upon investigation, he found a broken clamp caused by a faulty bearing. He immediately shut down the pump, preventing a potential shaft failure. Years of experience have made such vigilance second nature to the workers.
Xu Shuqing, the depot director, emphasizes, “We can’t afford any mistakes. Every operation must be perfect, and every data entry must be accurate.†To ensure precision, the depot has developed a unique five-step process for switching operations: clear instructions, careful checks, simulation, precise execution, and thorough inspection. Each step defines roles and standards clearly.
Beyond process control, the depot also produces video tutorials for standardized operations and compiles practical skill manuals for each position. Safety has become deeply embedded in the culture. Signs remind workers of the importance of safety, and daily briefings reinforce the message. Even the desks are equipped with “safe desk calendars,†and online platforms allow continuous learning.
To further promote safety awareness, the depot introduced a “safety exposure board†and organized events like safety speeches, board newspaper contests, and “Safety Star†evaluations. The goal is to instill the idea that “every day is a new start†when it comes to safety.
Technology plays a crucial role in enhancing safety. Chen Xi, a pump operator, praises the “Wireless Intelligent Electronic Inspection System,†which helps track inspection sites and alerts if something is missed. “It’s like a tool for security,†he says.
The base has also launched the “Safety E-System,†integrating work arrangements, planning, quality control, feedback, review, and evaluation into one platform. Employees can now check patrol status, monitor on-duty cadres, and access real-time data via GIS maps.
In addition, the depot uses video surveillance, automated control systems, and remote pipeline leak detection. Advanced digital systems cover all aspects of management, ensuring that even a single mouse click can control equipment, and a screen can monitor everything in real time.
Through technology, safety has become more efficient and reliable. Hidden dangers are identified and addressed before they escalate. With five advanced digital systems, six integrated information platforms, and employee-designed tools, the Dongying Crude Oil Storage Base continues to operate safely and efficiently, providing full protection for its long-term operations.
