Command of the Week
(New or interesting aspects of GHS that you may not know about)

(Requires GHS/BHS and the Load Editor (LE) module)

These commands are comparable in that they both report the "status" of tank loads. LOAD STATUS TANKS (which is a feature of the Load Editor module) is particularly well suited to reporting loading conditions. STATUS TANKS provides loading information at a more basic level.

Let's compare how each one reports the same tank loading. To simplify this example, only cargo tanks are loaded.

First is the STATUS TANKS report followed by LOAD STATUS TANKS.

As you can see, LOAD STATUS TANKS includes soundings, which are of interest to the ship. The STATUS TANKS report, on the other hand, omits soundings and includes centers of gravity which are useful for verifying the model. STATUS TANKS omits empty tanks by default but STATUS TANKS:ALL will include them.

Note that the total weight differs slightly between the two reports. The reason for that is STATUS TANKS gets its weight from the volume at the final surface level found in the solving iteration while LOAD STATUS TANKS takes the weight straight from the LOAD setting. STATUS TANKS /NOMINAL will give exactly the same result as LOAD STATUS TANKS. If the tank geometry is adequately defined, the difference will be small.

LOAD STATUS TANKS offers a rich set of options. Here are some of them:
  • Loads can be shown as weight in any of four units or as volume in any of seven units.
  • The right-hand column can show Sounding, Ullage, Reference Point Height, or Free Surface Moment.
  • The order in which the lines are presented can be according to ascending or descending values in a given column.
  • Empty tanks are shown by default, but they can be omitted.
  • Any selection of tanks can be shown using the form LOAD (tank list) STATUS TANKS.
  • An alternate format shows gross and net volumes for petroleum products. The loading shown in the image below demonstrates this.

The STATUS command can report many other things, but when it comes to showing tank loadings in a report, LOAD STATUS has all the advantages. The only advantage STATUS has in that regard is .... Well, we couldn't think of any. However, if your GHS/BHS configuration lacks the Load Editor module, we can understand that you might view STATUS TANKS as being preferable.

In a printed report, the first LOAD STATUS TANKS above might look like this:
