Ideas for Future
Development Sheet
Currently
I have recently finished a first cut at some rudimentary
spreadsheets for automating some of the calculations outlined within
this website. These spreadsheets include;
- preliminary
sizing calcs,
- hullform coefficient
estimations,
- preliminary weights
estimation,
- speed/power
estimation,
- area/volume
estimation,
- initial hullform
geometry estimate, and
- cost estimating routines.
Eventually I also hope to
eventually include;
- preliminary
seakeeping assessment information, and
- preliminary
stability assessments
In addition to this I am also
currently doing a more indepth review of some of my raw data in
the hopes of cleaning it up and perhaps trying to better develop
methods for the estimation of some of the major weight groups,
etc. One specific concept that I am considering is to try and
develop some form of "hullform parameter" that might better address
differences in the layout of different ship designs to allow the user
to assess the impacts of superstructure size and construction
materials, etc. Unfortunately currently, in using cubic number as
the ordinate in many of my weight estimating graphs, things like
superstructure size and construction material type get kind of lost in
the spread of data. By developing a new parameter (perhaps
similar in concept to the "hull equipment numeral" discussed in D.G.M.
Watson's book "Practical Ship Design" (Ref 10)) it may be possible to
better correlate things such as total structure weight and costs to
this value rather than relying on a term like cubic number which relies
solely on a vessels length, beam and depth. Unfortunately such an
effort will take some time to implement and as such is likely more of a
"far term" concept for future development. |
