What is meant by Total Observed Volume (TOV)?

Total Observed Volume (TOV) refers to the comprehensive measurement that accounts for not just the petroleum liquids in a storage tank but also includes any sediment or water that is in suspension within those liquids, while specifically excluding any free water that may be present. This definition is crucial for understanding the effective volume of liquid that is available for processing or transfer, as it takes into account the additional materials that can affect the usability of the petroleum products.

The significance of TOV lies in its role in ensuring accurate accounting during operations, allowing for better assessments of inventory and helping to prevent inaccuracies related to the quality and quantity of the products being stored or transferred. Understanding TOV is especially important in tankerman operations where precise measurements affect safety, efficiency, and compliance with regulations governing the handling of petroleum products.
