1. Preliminary Preparation & Safety Check
- Empty remaining fuel into compliant containers using specialized equipment
- Ventilate tank and surrounding area; test air fuel concentration
- Disconnect all power and piping connections; post warning signs
- Demarcate safe work area and prepare new tank, seals, and tools
- Verify new tank qualifications and quality compliance
2. Old Tank Disassembly & Site Cleanup
- Disassemble connecting components (piping first, then tank)
- Seal disconnected pipe joints to prevent impurity entry
- Lift old tank smoothly using specialized equipment
- Clean installation location; remove debris, rust, and old seals
- Check foundation flatness and load capacity; repair if needed
3. New Tank Installation & Piping Connection
- Precisely hoist new tank to location; adjust level and verticality
- Secure tank firmly to prevent displacement
- Connect inlet/outlet pipelines and monitoring system sequentially
- Check pipeline routing for rationality; ensure no twists or stress
- Install and test leakage monitoring device for real-time operation
4. Commissioning, Inspection & Handover
- Conduct sealing and pressure tests on new tank and connections
- Debug control systems; verify oil supply and monitoring functions
- Clean work site; remove warning signs; restore environment
- Perform trial run; observe operating status and fuel delivery stability
- Officially put into use after all indicators meet standards
Note: All procedures must comply with relevant safety regulations and environmental standards. Qualified personnel should perform specialized operations. Regular monitoring is recommended during initial operation period.
