DIESEL FUEL POLISHING

• Fuel Polishing Unit (3-Stage Filtration System)
  A dedicated fuel polishing system utilizing three-stage progressive filtration to remove contaminants at different levels, achieving final cleanliness of up to 5 microns. This ensures effective removal of dirt, rust, and sludge from stored diesel fuel.
• Circulation pump and hoses for continuous fuel processing
• Replaceable filtration elements (coarse to fine stages)
• Inspection and monitoring tools

• 1–2 Technical Personnel for installation and monitoring
• 1 Supervising Engineer / Analyst
• Coordination with site personnel during monitoring period

✔ Execution will be coordinated with site personnel to ensure safe and efficient inspection

Processing time is based on a system flowrate of approximately 100 liters per minute.

For a typical 14,000-liter diesel tank:

• 1 filtration cycle: approximately 2–2.5 hours
• 3 filtration cycles (recommended): approximately 6–7 hours total processing time

Including setup, monitoring, and system adjustments, the total service duration is typically:

👉 Approximately 1 working day per tank

Our pump inspection and evaluation services are performed in accordance with internationally recognized standards and proven industry practices to ensure accuracy, reliability, and safety.

We align our work with:

• API Recommended Practices – for equipment reliability and oil & gas applications (where applicable)
• ISO Standards – for structured maintenance and quality management systems
• ASTM Standards – for material evaluation, testing, and inspection procedures
• Hydraulic Institute (HI) Guidelines – for pump performance, operation, and system optimization
• NFPA Standards – for fire pump systems and fire protection applications (when applicable)
• OSHA Safety Practices – to ensure safe execution of all field activities
• OEM Recommendations – to maintain compliance with manufacturer specifications
• Industry Best Practices – based on real-world experience in rotating equipment and pump systems

After the service, a Service Report covering the full scope of work performed will be provided. This serves as formal documentation of findings, assessment, and recommended actions.

The report includes:

• Inspection Summary
  Overview of system condition based on visual checks, operational observations, and filtration results
• Findings & Observations
  Identified issues related to fuel condition, contamination level, and system condition
• Before & After Condition (if applicable)
  Visual comparison of fuel condition and clarity improvement
• Photo Documentation
  Supporting images of the process, setup, and observed conditions
• Filtration & Processing Details
  Summary of filtration cycles performed and general system operation
• Recommendations
  Suggested actions to maintain fuel quality and prevent future contamination

Actual Fuel Polishing Result
From hazy, contaminated diesel to visibly clearer fuel after 4.5 hours of processing (2 filtration cycles)—demonstrating effective removal of particulate contaminants and improved fuel condition.

The execution of the service is subject to site accessibility, operational conditions, and required safety clearances. All equipment and work areas must be reasonably accessible to allow proper inspection, assessment, or execution of the agreed scope. Certain activities may require the equipment or system to be operational, while others may necessitate partial or full shutdown, depending on the nature of the work.

All necessary permits to work (PTW), safety clearances, and site approvals must be secured prior to execution to avoid delays. Coordination with site personnel is required to ensure safe and efficient completion of activities. The provision of site support such as access equipment, manpower assistance, utilities, and isolation (if required) shall be the responsibility of the client unless otherwise agreed.

Environmental and site conditions, including but not limited to weather, confined spaces, hazardous areas, and operational limitations, may affect the execution schedule and duration of the service.

The service is based on a non-intrusive approach and is limited to externally accessible components and observable conditions unless otherwise specified in writing. No dismantling, internal inspection, or major repair works are included under this scope unless explicitly stated.

All findings, assessments, and recommendations are based on the condition of the equipment or system at the time of service and on available operational data provided or observed. Recommendations are intended to support maintenance, operational, and engineering decisions but do not constitute a certification of equipment integrity, performance, or regulatory compliance.

Any additional works identified during the execution of the service that fall outside the agreed scope may be subject to separate evaluation, costing, and approval.

Note: The indicated scope, exclusions, and duration are preliminary and may be adjusted following detailed assessment of site conditions, operational constraints, and project-specific requirements.
