The term "ROB Bunker Survey " typically refers to an inspection or assessment carried out on a vessel's bunker fuel tanks while the fuel remains on board. Bunker fuel tanks are used to store the fuel that powers ships or large vessels.

The purpose of a ROB Bunker Survey is to evaluate the condition and integrity of the fuel tanks, ensuring they are suitable for storing and supplying fuel safely. The survey is typically conducted by marine surveyors or inspectors who specialize in assessing the structural integrity, cleanliness, and operational functionality of the bunker fuel tanks.

During the survey, various aspects are examined, including the tank's physical condition, corrosion, leakage, sediment or sludge accumulation, and compliance with safety regulations. The survey may involve visual inspections, measurements, testing, and sampling of the fuel to assess its quality.

The ROB Bunker Survey is essential for maintaining the safety and efficiency of the vessel's fuel system. It helps identify any issues or potential risks related to the bunker fuel tanks, allowing for timely maintenance or repairs to prevent fuel leaks, contamination, or other hazards.

• It's important to note that specific regulations and guidelines may vary depending on the maritime authority or organization overseeing the vessel's operation.
