What is Gross Observed Volume (GOV)?

Gross Observed Volume (GOV) refers specifically to the total measured volume of all petroleum liquids, sediment, water in suspension, and free water. This measurement is crucial in the context of tankerman operations as it provides an accurate representation of the actual contents in a storage tank or during loading and unloading operations.

Understanding GOV is essential for ensuring compliance with regulatory requirements, maintaining safety during transfers, and accurately determining the amount of product that can be shipped or received. It considers all components of the volume, including any impurities or water that might be present, which can significantly affect the overall inventory and quality of the petroleum product.

The other options represent different concepts related to oil measurement and environmental considerations. The calculated volume based on average temperatures pertains to a method of adjusting measurements to account for thermal expansion or contraction, while estimated pollution from a discharge relates to environmental impact assessments. The historical volume of products held in reserve is concerned with storage capacities and inventory records, but none of these definitions aligns with the perspective of the total measured volume that GOV specifically addresses.
