Documentation and tutorials : https://bv-dr.gitlab.io/Snoopy

Snoopy is an open source library for marine applications. Among other things, it contains the following sub-packages

• Spectral : Routines for spectral analysis of sea-keeping results

  • Wave spectra (Jonswap, Ochihubble, spreading function…)

  • Manipulation of transfer function (RAOs)

  • Response spectrum

  • 2nd order response spectrum

• TimeDomain

  • Reconstruction of seakeeping results in time domain (1st and 2nd order)

  • Convolution for wave radiation in time domain (from added-mass).

  • Upcrossing analysis

• Fatigue

  • Rainflow counting

  • SN-Curves

  • Spectral fatigue

• Meshing

• WaveKinematics : (Linear, wheeler stretching, 2nd order…)

• Statistics

  • Peak Over Threshold

  • Long term analysis

  • IFORM contour

Example of use

>>> from Snoopy import Spectral as sp
>>> spec = sp.Jonswap( hs = 1.0 , tp = 10.0 , gamma = 1.0)
>>> spec.plot()

How to install

Snoopy is available on pypi.org and can be using pip:

pip install snoopy-bv

In case conda is used, it is recommended to install dependencies using conda (hence the –no-deps in above command line):

conda install xarray numpy scipy pandas matplotlib h5py tqdm Deprecated
pip install snoopy-bv --no-deps
