A Python package for ship Resistance estimation
Requirement: Python >= 3 and numpy, scipy.
Installation: pip install PyResis.
To estimate propulsion resistance of a ship with following dimensions at 2 m/s:
| Dimensions | Value | Unit |
|---|---|---|
| Length | 5.72 | metres |
| Draught | 0.248 | metres |
| Beam | 0.76 | metres |
| Slenderness coefficient | 6.99 | |
| Prismatic coefficient | 0.613 |
With PyResis it is easy to get a resistance estimation by:
from PyResis import propulsion_power
ship = propulsion_power.Ship(5.72, 0.248, 0.76, 2, 6.99, 0.613)
ship.resistancePropulsion power estimation:
ship.propulsion_power()
