Bunker surveys conducted by SOI surveyors are crucial for accurately determining the amount of bunker fuel (Fuel Oil and Gas Oil) aboard a vessel at specific stages, typically before and after a time chartering period. Here’s a detailed outline of how these bunker surveys are conducted and their importance:

1. Purpose of Bunker Surveys:

   • Pre-Chartering:

     • Establishes the initial quantity of bunker fuel onboard the vessel before entering into a time charter agreement.
     • Provides a baseline measurement for bunker quantity at the start of the charter period (on-hire).

   • Post-Chartering (Redelivery):

     • Conducted at the end of the charter period to determine the remaining quantity of bunker fuel.
     • Ensures accurate measurement of bunker fuel consumed during the charter period.
     • Identifies any discrepancies in bunker quantities that may arise during the charter period.
   •  

2. Methodology:

   • SOI surveyors use internationally recognized methods and modern equipment to measure bunker quantities accurately. This involves physical measurement of bunker tanks, taking into account any changes in density or temperature that may affect volume calculations.

3. Correction Factors:

   • During the charter period, adjustments may need to be made to account for bunker fuel consumption based on charter party agreements. This ensures that the quantity of bunker fuel stated at re-delivery accurately reflects the amount consumed during the charter period, considering factors such as vessel speed, weather conditions, and operational efficiency.

4. Documentation and Compliance:

   • Detailed reports are prepared documenting the initial and final bunker quantities, along with any corrections applied based on consumption during the charter period. These reports are crucial for contractual compliance, financial settlements, and resolving any disputes related to bunker fuel consumption.

5. Accuracy and Reliability:

   • The accuracy of bunker surveys is essential for financial accountability and operational planning. By employing rigorous measurement techniques and adhering to industry standards, SOI ensures that bunker quantities are stated with precision, providing confidence to charterers, owners, and other stakeholders.

In summary, bunker surveys conducted by SOI play a pivotal role in maritime operations by providing accurate measurements of bunker fuel quantities before and after charter periods. This process facilitates transparency, compliance with charter party agreements, and effective management of fuel resources aboard vessels.
