The DeRisk Database

The DeRisk database is an extensive database of long-crested (2D) nonlinear wave kinematics for computation of extreme loads on offshore structures.The database was produced by running the nonlinear potential flow model OceanWave3D [1] on a gently sloping domain. The performed computations spanned a large parameter space, defined by nondimensional water depth, significant wave height and spectral peak period. A work containing a thorough description and validation of the current computations and of the database concept is currently under preparation [2].The DataBase is openly accessible under the conditions of the present license.Routines for interacting with the database, and usage examples are located at:https://gitlab.windenergy.dtu.dk/fabpi/deriskdatabase.git[1] Engsig-Karup, Allan Peter, Harry B.
