Strapping tables incorporate corrections for which factors?

• A. Temperature and Pressure
• B. Trim and List
• C. API gravity and Temperature
• D. Volume and API

Answer: (B)

Strapping tables are used to determine cargo quantity from measurements inside a tank, and the main factor they correct for is the ship’s attitude. When a vessel trims fore or aft or lists to one side, the geometry of each tank changes, so the same measured height of liquid does not correspond to the same actual volume as it would with a level hull. The strapping table provides correction values for those trim and list conditions, allowing you to convert the observed readings into a true volume (and thus weight) more accurately at the moment of measurement. This correction is essential for accurate loading and discharging planning because even small attitudes can noticeably alter the apparent quantity in a tank. Density-related adjustments, such as those for temperature or API gravity, are handled separately when converting volume to mass, not within the strapping table itself.
