1. Adhere strictly to the design specifications during the planning phase. Before putting the new tank into service, a meticulous quality inspection must be conducted. A trial run involving the filling of the tank, along with the raising and lowering of the floating roof, is essential. The floating roof must move smoothly, seal properly, and ensure that all components are fully functional.
2. Conduct thorough maintenance of oil tanks while maintaining high-quality standards. The primary departments should meticulously review and approve the maintenance plan. Prior to maintenance, a detailed and comprehensive assessment of the tank's condition (including all accessories) must be carried out to ensure the maintenance plan is thorough and accurate, preventing potential leaks. Enhanced on-site safety oversight and acceptance procedures are necessary. Each maintenance task must be verified at the site, and management of both internal construction units and design processes should be strengthened to improve overall maintenance quality. Special attention should be given to hidden projects, including intermediate acceptance checks and quality inspections, to avoid accidents.
3. Intensify regular inspections and maintenance of the inner floating roof. Regularly check for leaks, assess the degree of deformation and stress on the floating roof, monitor the aging and wear of the sealing tape, and verify the reliability of the alarm systems. Ensure that the guide tubes and wheels maintain proper alignment without causing imbalance or friction. During winter, prior to oil transfer operations, thoroughly inspect the sealing devices to prevent freezing on the tank walls. Any issues identified during inspections should be addressed promptly and systematically.
4. Install a diffuser pipe on the oil inlet line. 5. When restarting an oil tank after repairing pipelines, all air must be purged through relevant connectors.
5. Enhance the design of the inner floating roof to improve its resistance to sinking and flooding. For instance, adopting a floating compartment or ring compartment design ensures that the inner floating roof remains stable even if two adjacent compartments leak. These designs also feature a 1.5% slope, allowing oil splashed onto the roof to flow back into the tank, preventing accumulation on the floating roof and facilitating drainage. This improves both buoyancy and operational efficiency.
6. Optimize operational procedures and strictly adhere to established guidelines. Upstream equipment should stabilize production, avoiding fluctuations that could lead to oil spillage or non-productive losses. Control the rate of oil intake strictly, and rigorously follow operational protocols to prevent unauthorized actions.
7. Strengthen routine inspection practices, enhancing the quality of inspections and the ability to identify potential problems early. Improve the criteria for safety inspections outlined in the annexes, reinforce equipment management systems, and strengthen evaluations and revisions related to spot checks and economic accountability.
8. Reinforce operational accountability by installing high-level alarms and removing fixed ladders attached to the roof. Clearly define management roles, continuously improve professional skills, and provide ongoing training and guidance for technical staff. Elevate the technical and managerial proficiency of leadership teams.
In conclusion, these measures aim to ensure the safe and efficient operation of oil storage facilities, reducing risks and improving overall performance.
