Fuel and Fresh Water Bunkering refer to the processes of supplying ships with fuel oil and fresh water, respectively, at ports or during anchorage. These are critical operations in maritime logistics, and they require careful planning and safety considerations.
1. Fuel Bunkering
Definition: The process of supplying a ship with fuel oil for its engines, generators, or boilers.
Types of Fuel:
- Heavy Fuel Oil (HFO)
- Marine Diesel Oil (MDO)
- Marine Gas Oil (MGO)
- Low Sulfur Fuel Oil (LSFO)
Bunkering Locations:
- Port (at berth)
- Anchorage (offshore)
- Ship-to-ship transfer (STS)
Bunkering Process:
- Pre-bunkering checklist – Includes safety checks, communication setup, and documentation.
- Connection – Hoses connected between the bunker barge/tanker and the receiving vessel.
- Transfer – Controlled pumping of fuel, monitoring flow rates and tank levels.
- Completion & Disconnection – Line draining, disconnection, and sealing.
- Post-bunkering checks – Sampling, tank soundings, and documentation (e.g., Bunker Delivery Note – BDN).
Key Documents:
- Bunker Delivery Note (BDN)
- Safety checklists
- Fuel sample records
2. Fresh Water Bunkering
Definition: The process of supplying fresh (potable) water to a vessel for use by crew and passengers or in ship operations.
Sources:
- Shore-based water supply
- Barge or tanker
- Watermakers (onboard desalination systems)
Fresh Water Bunkering Process:
- Pre-operation inspection – Ensure cleanliness and safety of hoses and tanks.
- Connection – Hoses connected to the ship’s freshwater intake.
- Transfer – Freshwater pumped into ship’s tanks.
- Monitoring – Check for flow rate and contamination.
- Disconnection & Sampling – Final water quality check and hose disconnection.
Key Considerations:
- Water quality standards (WHO or local port authority)
- Avoiding contamination
- Flow rate control to prevent tank overfill
Safety & Environmental Precautions
- Fire safety and spill prevention (especially during fuel bunkering)
- Use of drip trays and spill kits
- Crew training and PPE
- Environmental regulations (e.g., MARPOL Annex VI for fuel)
