Since the advent of the computers onboard most ships have a dedicated draft
calculation software.
However, as a surveyor I still carried with me, my own Excel program in a neat
pen-drive... always comes in handy when the ship's own programs do not
seem to work... or when they lack Class Approval.
I have posted it here for those who might need it as many have asked for it in
the past. It is a generic program which is adoptable to any ship using the
ship's current hydrostatic data.
The program has 5 tabs; a blank form, an initial survey form, a blank form for
final survey with initial calculations embedded, a final calculation form and
then a summery of both surveys with the cargo out-tun.
Go to Draft Calculation
For those who are more discerning officers there is an excellent maritime
package of Draft Survey Calculation, Lashing Calculation and a Route Planner on
the
XCBA.com
download site. I have used this on a bulk carrier and it is very effective.
One need to enter the ship's hydrostatics initially and thereafter life becomes
a song!
The Route Planner produces a Voyage Plan as required by the STCW-Code A-VIII/2
Part2 - Quite a neat piece of work and is handy for any 2nd Mate...

What I recommend is, take the installation package (an .exe file) on your
pen-drive when you go on board and install it on one of the machines on board -
not on the machine that runs the Loadicator please!
With the arrival of Satelite Navigation and the GPS ship's officers have lost the art
of taking a sight. But what I have noticed during my surveys is that they are
not even taking a compass error which is very important for safe navigation...
The pain of having to do ABC tables probably is the cause for this.
I have a working copy of the SightMaster for Windows which makes it extremely
easy to use with compass errors as well as identification of stars.
Unfortunately it is not possible to upload it here as it contains supporting
files in its folder.
If anyone is interested you may e-mail me and I shall gladly zip up
and send you the entire folder...
Many times surveyors skip the volume correction when calculating bunkers and
this can cost money, especially when dealing with a large quantity delivered.
Shell has a BunkerCalc Program which greatly simplyfies this task and it runs on
a PC.

I also have a Port Distance Calculator which runs on a PC. You may e-mail me
with the above link and I will send you the folder.
Happy Calculations!!!
