Bunkering via road tanker is a widely used method of marine fuel transfer for vessels in port. However, the process involves operational, environmental, and safety risks if not managed correctly.
This guide from PE Fuel Distributors explains the standard safety procedures for bunkering via road tanker, including preparation, monitoring, and emergency response. These procedures help ensure safe fuel transfer operations, regulatory compliance, and environmental protection.
What Is Bunkering via Road Tanker?
Bunkering refers to the process of supplying fuel to ships. When performed via road tanker, fuel is transported by tanker truck and transferred directly to a vessel’s fuel tanks through hoses connected at the manifold.
This method is commonly used for:
- Harbour and port refueling
- Fishing vessels
- Coastal cargo vessels
- Small commercial ships
- Offshore support vessels
Because fuel transfer involves flammable materials and environmental risk, strict safety procedures must be followed.
Road Tanker Bunkering Safety Procedure
The following operational checklist outlines the standard process for safe bunkering operations.
1. Pre-Arrival Planning
Before the road tanker arrives on site, the bunkering operation must be properly planned.
Key checks include:
- Confirm bunker nomination and fuel grade
- Verify Material Safety Data Sheet (MSDS) availability
- Check weather and sea conditions
- Confirm transfer quantity and pumping rate
- Issue a pre-transfer safety checklist
Proper planning reduces operational risks and prevents delays during fuel transfer.
2. Road Tanker and Equipment Inspection
Before bunkering begins, the road tanker and equipment must be inspected.
Important inspection points:
- Check tanker for leaks, corrosion, or structural damage
- Verify tanker calibration certificate
- Inspect hoses, couplings, and gaskets
- Confirm fire extinguishers are present
- Ensure spill containment kits are available
This inspection ensures all equipment meets marine fuel transfer safety standards.
3. Safety Briefing and Communication Protocol
A toolbox talk should be conducted with all personnel involved in the bunkering operation.
During the briefing:
- Establish communication signals
- Exchange emergency contact details
- Confirm the emergency stop procedure
- Review responsibilities of each operator
Clear communication is essential to maintain safe bunkering operations.
4. Vessel Preparation
The receiving vessel must be properly prepared before fuel transfer begins.
Preparation includes:
- Confirm available capacity in receiving fuel tanks
- Close unused valves
- Plug deck scuppers to prevent pollution
- Install drip trays under connection points
- Place safety signage
These steps help reduce the risk of fuel spills and environmental contamination.
5. Hose Connection and Grounding
The next stage involves safely connecting the fuel transfer hoses.
Key safety requirements include:
- Properly align the road tanker and vessel manifold
- Bond or earth the tanker to prevent static discharge
- Secure hose connections
- Conduct pressure testing before pumping
Correct hose connection prevents leaks during fuel transfer.
6. Commencing the Fuel Transfer
Fuel transfer should begin gradually.
Operators should:
- Start pumping at a slow rate
- Monitor pressure levels continuously
- Maintain communication between vessel and tanker
- Inspect hose connections for leaks
Controlled pumping helps maintain safe bunkering conditions.
7. Monitoring During Fuel Transfer
Continuous monitoring is essential throughout the bunkering process.
Operators must:
- Maintain watch on the manifold
- Track fuel transfer progress
- Monitor tank soundings
- Prevent tank overflow
Regular checks help ensure the safe and accurate delivery of marine fuel.
8. Completion of Transfer and Disconnection
When the transfer is nearing completion:
- Gradually reduce pumping speed
- Blow the line clear if permitted
- Close valves in the correct sequence
- Disconnect hoses carefully
- Drain hoses into drip trays
Following proper shutdown procedures helps prevent spills.
9. Post-Transfer Documentation
After bunkering is complete, final procedures must be followed.
These include:
- Taking final tank soundings
- Completing the Bunker Delivery Note (BDN)
- Obtaining signatures from responsible parties
- Removing scupper plugs
- Clearing equipment and safety signage
Proper documentation ensures traceability and compliance.
Emergency Bunkering Procedure
If a spill or safety incident occurs during bunkering:
- Stop the fuel transfer immediately
- Activate the emergency shutdown system
- Contain the spill using the spill response kit
- Notify the relevant port authority
- Implement the spill response plan
Fast response minimizes environmental damage and operational risk.
