Nautical Term: OBQ
Definition of OBQ
On Board Quantity (OBQ) refers to the amount of a specific substance or material that is stored on board a vessel. For instance, a ship’s OBQ for fuel might be calculated based on the ship’s fuel consumption rate and the amount of fuel currently on board.’
(For example: Our ship’s current OBQ for fuel is sufficient for a two-week voyage at our usual cruising speed. However, we should keep an eye on our fuel consumption rate and consider refueling if our OBQ drops below the amount required for our next destination.).
