What statement is true when considering bunkering tank volume?
AI Explanation
The correct answer is C) Generally, topping-off begins at 90% of tank volume, and filling stops at 95% of tank volume.
This is the correct answer because it aligns with the standard industry practice and regulations for bunkering tank volume. Typically, topping-off of tanks begins when the tank volume reaches around 90% to allow for expansion of the fuel and to prevent overfilling. Filling is then stopped at around 95% of the tank volume to leave a small air space and avoid spills or overflow.
The other options are incorrect because they do not accurately reflect the typical bunkering tank volume practices. Option A and B allow for a larger top-off range, which is not the industry standard. Option D allows for filling up to 100% of the tank volume, which is not recommended to prevent overfilling and potential spills.
