Our Comprehensive Bunker & Marine Surveys in Mozambique
We offer a full spectrum of bunker survey services at all major ports in Mozambique, including Maputo, Beira, Nacala, Pemba, and Quelimane. Each bunker survey is designed to provide maximum oversight and risk management for any operational scenario.
Expert Bunker Quantity Survey (BQS) / Bunker Delivery Survey
Our cornerstone service for any vessel receiving bunkers in Mozambique. Our highly trained bunker surveyors execute a complete, transparent verification of the entire bunkering operation. This goes beyond simple readings to perform a systematic bunker survey of the transfer from start to finish.
- Pre-bunkering conferences with the Chief Engineer and bunker barge personnel to align on procedures for the bunker survey in ports like Maputo or Beira.
- Thorough gauging of all tanks on both the receiving vessel and the bunker barge before and after delivery by our professional bunker inspectors.
- Independent verification of temperatures, densities, and the correct application of Volume Correction Factors (VCF) during the bunker survey.
- Vigilant, continuous monitoring of the entire delivery process by our bunker surveyor to detect and challenge any irregularities.
- Issuance of a certified, independent bunker survey report to robustly verify or challenge the supplier’s Bunker Delivery Note (BDN).
On-Hire & Off-Hire Bunker Surveys
These bunker surveys are indispensable at the commencement and conclusion of a charter party agreement. They are the most effective tool to eliminate costly and time-consuming disputes over fuel inventories.
Our bunker surveyors establish the definitive quantity of all fuel grades and lubricating oils on board at the precise point of delivery or redelivery in any Mozambican port, providing a clear and final bunker survey record for all parties.
- On-Hire Bunker Survey: Delivers an impartial, verified record of all fuels on board. This protects the incoming charterer from paying for “paper tonnes” that don’t exist and provides the owner with a clear, factual baseline.
- Off-Hire Bunker Survey: Determines the exact quantity of fuel remaining on board when a charter concludes. This safeguards the ship owner by ensuring the vessel is redelivered with the contractually agreed fuel quantity as per the final bunker survey.
Ship On/Off-Hire Condition Surveys in Mozambique
Alongside fuel, the physical condition of a vessel is a primary source of potential disputes. Conducting a detailed Ship Condition Survey concurrently with the On-Hire or Off-Hire bunker survey at any Mozambican port provides an invaluable, impartial record of the vessel’s state.
This service is a cornerstone of prudent risk management. Our bunker surveyors perform a painstaking visual inspection of the vessel’s cargo-related infrastructure and structural components, focusing on:
- Cargo Holds, Hatch Covers & Coamings: Checking for structural integrity, water-tightness, cleanliness, and any pre-existing damages.
- Deck, Cranes, and Cargo Gear: A thorough assessment of the operational condition of cranes, derricks, winches, and all associated cargo handling equipment.
- Overall Hull & Superstructure Condition: Systematically noting any significant dents, corrosion, or damage to the vessel’s exterior.
The final, exhaustive report, richly supplemented with high-resolution photographic evidence from our bunker inspectors, acts as a definitive “before and after” record. This protects the charterer from claims for pre-existing damage and provides the owner with a powerful tool for safeguarding their asset’s value after operations in Maputo, Beira, or Nacala.
