Tank Soundings

Tank sounding tables are interesting because of the variety of formats and requirements which are encountered. Since some of those requirements are quite specific, we made a special module to handle them.

GHS also produces tank sounding tables with a considerable amount of flexibility in the makeup of the table. While the tank tables from the GHS main program are intended primarily for design work, the TS module produces sounding tables for use in the field. TS offers five table formats:

• 1) Gallons vs. Sounding in inches, arranged in vertical columns;
• 2) Gallons vs. Sounding in feet and inches, arranged in a 12-column table;
• 3) Gallons, Cubic Feet, Center of Buoyancy, Moments of Inertia vs. Sounding in feet;
• 4) Same as 3 except a Trim Correction column replaces the Longitudinal Moment of Inertia;
• 5) Cubic Feet, Gallons and Long Tons vs. Sounding and Ullage in feet and inches.

Formats 1 and 2 are more compact than any of the formats available in GHS and are therefore especially attractive for use in the field if only volumes are needed.

Formats 2, 3, and 4 meet specific US Navy requirements. Formats 3 and 4 include special interpolations at breakpoints.

Format 5 shows both sounding and ullage simultaneously.

We expect that eventually, computers will be so accessible, reliable, and common that tank sounding tables on paper will cease to be produced. Until that happens we can add new formats to the TS program to meet any special needs.
