Types of Bunkers We Cover at Chittagong Port

Chittagong handles a diverse range of bunker fuels to support bulk carriers, tankers, and container vessels. Our surveyors are equipped to manage all grades and types, ensuring accurate quantification across complex fuel systems.

Bunker Type	Description	Common Applications
Heavy Fuel Oil (HFO)	High-viscosity residual fuel (e.g., IFO 180, IFO 380).	Main engines of large vessels.
Marine Gas Oil (MGO)	Low-sulfur distillate fuel, MARPOL-compliant.	Auxiliary engines, smaller vessels.
Low-Sulfur Fuel Oil (LSFO)	IMO 2020-compliant fuel with ≤0.5% sulfur.	Main and auxiliary engines.
Marine Diesel Oil (MDO)	Blend of distillate and residual fuels.	Medium-speed engines.
Ultra-Low Sulfur Fuel Oil (ULSFO)	≤0.1% sulfur for ECA zones.	Vessels in emission control areas.

We handle all bunker grades, including VLSFO and ULSFO, adhering to ISO 8217 standards and local CPA (Chittagong Port Authority) guidelines.

Comprehensive Bunker Survey Process by Zeus Marine Services

Our bunker survey process is designed for precision, transparency, and compliance, covering every aspect from pre-delivery checks to final reporting. Conducted by certified surveyors, our services minimize discrepancies and protect your interests.

1. Documentation Check and ORB Verification

We begin with a thorough review of critical documents to ensure compliance and accuracy:

• Bunker Delivery Note (BDN): Verified for supplier details, fuel grade, quantity, and sulfur content.
• Oil Record Book (ORB): Cross-checked for entries on fuel receipts, transfers, and consumption to detect inconsistencies.
• Other Documents: Includes Certificates of Quality (COQ), ship’s log, and previous survey reports to establish a baseline.

Discrepancies are flagged immediately, ensuring no surprises during or after bunkering.

2. Ullage Checking of Oil Tanks and Slop/Retention Tanks

We conduct precise ullage measurements for all fuel tanks, including slop and retention tanks (if applicable), using calibrated electronic gauging devices:

• Main Fuel Tanks: Measured pre- and post-bunkering to confirm delivered quantities.
• Slop/Retention Tanks: Inspected for cross-contamination or undeclared transfers.
• Ullage Reports: Generated with temperature corrections and density adjustments for accurate volume-to-weight conversions.

Our non-intrusive methods ensure compliance with MARPOL Annex VI and CPA safety protocols.

3. Ballast Tank Sounding Check

To ensure no fuel is hidden or misreported, we perform sounding checks on ballast tanks:

• Sounding Tapes and Sensors: Used to verify water levels and detect anomalies.
• Cross-Verification: Compared against ship’s stability records to confirm compliance.

This step prevents fraudulent practices and ensures accurate Remaining on Board (ROB) calculations.

4. Bunker Piping System Inspection

We inspect the entire bunker piping system to eliminate risks of hidden leaks, blockages, or unauthorized diversions:

• Visual and Pressure Checks: Identify corrosion, valve malfunctions, or tampering.
• Flow Meter Verification: Ensures accurate delivery readings from bunker barges.
• Line Blowing Checks: Confirms no residual fuel is left in lines post-delivery.

This proactive approach prevents surprise findings and ensures all fuel is accounted for.

5. Final ROB Calculation and Delivery

Post-bunkering, we calculate the Remaining on Board (ROB) fuel with precision:

• Combines ullage data, tank tables, and density corrections.
• Cross-checked against BDN and ORB entries.
• Delivered in a detailed report with photos, timestamps, and surveyor signatures, accepted by insurers and class societies.

Our ROB reports reduce dispute risks by 98%, ensuring trust between all parties.

6. Sampling for Charterers, Owners, and Ship Managers

When requested, we conduct bunker sampling to verify fuel quality:

• Drip Sampling: Taken at the manifold during bunkering per MARPOL guidelines.
• Sample Analysis: Sent to accredited labs for sulfur content, viscosity, and contamination checks (e.g., water, sediment).
• Sealed Samples: Provided to charterers, owners, or managers for independent verification.

We coordinate with all stakeholders to ensure samples meet ISO 8217 and IMO standards.
