SHIPMANAGER-88 uses the original ASTM formula to calculate specific gravity and volume correction factors of oil and petroleum products at observed temperatures.

It provides the ability to print the calculated results and to combine the application of the original ASTM formula and method to provide the most accurate resulting quantity of cargo on board. In the intuitive form, the user can input basic properties of crude oil and generalized petroleum products such as API gravity or density at the standard API or random temperature. It provides an ullage report in an international format, with signature-ready before-loading and after-discharge reports that are easy to be produced for terminal representatives, surveyors, vessel masters, and chief officers.
