On January 16, it was reported that Dalian Petrochemical Company had successfully completed the decommissioning and clearing of 312 storage tanks by the end of December 2025, achieving this safely, efficiently, and in an environmentally responsible manner. The project—which involved cutting off production-related water and power supplies and removing raw materials, finished products, and equipment—was brought to a successful conclusion.
2025 marked a pivotal year for Dalian Petrochemical’s transformation and upgrading. Facing various challenges, the company’s Party Committee orchestrated a strategic, systematic approach. By implementing "seven major plans," the company ensured the smooth and orderly completion of key tasks—such as material disposal and tank decommissioning—thereby laying a solid foundation for the enterprise's transition into a new stage of development.
During the intensive decommissioning campaign, the Party Committee established a dedicated task force. This team meticulously mapped out the decommissioning schedule, strictly enforced standardized operating procedures, strengthened safety supervision throughout the process, and continuously optimized cleaning technologies, ensuring the safe, high-quality, and efficient disposal of all storage tanks.
The company prioritized standards to reinforce its management foundation. It formulated and issued guidelines on standardized management for mechanical tank cleaning and key safety control points for tank cleaning operations. These measures implemented standardized control across the entire workflow, systematically enhancing operational standardization and management precision. A grid-based management system was adopted, featuring specialized working groups and designated responsibility zones to ensure comprehensive safety inspections of high-risk operations. A mechanism comprising daily inspections, weekly reviews, and monthly evaluations was established to maintain safety and control throughout the operations.
Technological innovation was leveraged to boost operational efficiency. The company significantly improved tank cleaning speeds through technical upgrades. In the mechanical cleaning phase, a "closed-loop self-cleaning" mode replaced the traditional "oil-based cleaning" method, greatly simplifying processes and conserving resources. For manual cleaning, the company optimized an integrated workflow—combining firewall dismantling, tank wall openings, and collaborative mechanical-manual sludge removal—which significantly reduced risks associated with confined-space work and lowered labor intensity, achieving a balance of safety, efficiency, and cost-effectiveness.
Coordinated efforts by the task force helped resolve execution challenges. Adopting a problem-oriented approach, the company effectively cleared bottlenecks through timely coordination, on-site guidance, and targeted measures. To address reduced material fluidity caused by low temperatures, the company introduced a high-efficiency fuel-fired boiler heating process, ensuring continuous and stable operations. Implement a management mechanism for contractors that combines "fixed-quantity labor contracting" with "performance-based incentives" to fully mobilize personnel enthusiasm and achieve simultaneous improvements in construction efficiency and work quality.
