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:
