Merchant ships preliminary dimensioning
In the form that appears below the user indicates the type and size of a merchant ship whose main features wants to know and getting in response, a preliminary approximation of the same.
This estimate is based on statistical analysis and regressions (Ref.1) of ships dimensions, being actual ships or designed projects, linking each of the characteristics of the ship with a single parameter describing her size ( deadweight, cargo volume, number of containers etc.). The resulting characteristics should therefore be considered as a first approximation only, which will give an idea of the characteristics of the new project or will serve as an initial basis for a more detailed definition by usual design procedures (Ref.2).
The types of considered vessels are:

The types of considered vessels are:
- Bulkcarrier (single hull)
- Crude oil tanker (double hull)
- Product tanker
- Chemical carrier
- General Freighter
- Coaster
- Reefer
- LPG gas carrier,
- Container vessel.
The initial drop-down list-box "Ship Type" indicates, for each type, the minimum and maximum allowable values of the target characteristic, Deadweight (Tm), Cargo Volume (m3) Total number of 20-foot containers (TEU). The lower limit is expressed in thousands (k) and in the case of Gas Carriers the upper limit as well.
But in all cases the number to be typed (no period nor comma ¡) is in units, not thousands.
LPG gas carriers may be pressurized or refrigerated type. Container ships between 3.500 and 4.500 TEU can be Panamax or not, as desired by the user.
