Tank sounding tables are interesting because of the variety of
formats and requirements that are encountered. Since some of
those requirements are quite specific, we made a special module
to handle them.
The GHS main program can also produce tank sounding tables
(the TC command) 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
six table formats in either English or metric mode.
TS formats with English units:
- 1. Gallons vs. Sounding, 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
- 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
- 6. Gallons/BBls, Cu.ft., Weight, Center and FSM vs. sounding
Gallons may be either U.S. or Imperial.
TS formats with metric units:
- 1. Liters vs. Sounding arranged in vertical columns
- 2. Liters vs. Sounding in meters and decimeters, arranged in a 10-column table
- 3. Gallons, cubic meters, center and moments vs. Sounding
- 4. Same as 3 except a trim correction column replaces the longitudinal moment of inertia
- 5. Cubic meters, Gallons/Barrels and metric tons vs. sounding & ullage
- 6. Gallons/BBLs, cubic meters, metric tons, center and FSM vs. sounding
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.
TS Extensions - TSX
TSX calculates two types of tank sounding tables that show a range of trims:
1. Volumes at given sounding or ullage increments for a range of trims at a given heel.
2. Sounding corrections at given sounding increments for a range of trims and/or heels.
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.
