Research on floating Oscillating Water Columns (OWCs) is still being carried on by several teams. The use of a new geometry configuration for a non-axisymmetric floating OWC is proposed. Time domain models may be used to numerically simulate the behavior of the device, however if fast computing is required stochastic analysis may be used. Mathematical modeling using stochastic analysis is presented. The algorithms needed to compute the hydrodynamic coefficients that take into consideration the air pressure oscillation inside the air chamber as well as the rigid body motions of the device are described in detail. Analytic equations for device's dynamic behavior are presented. Numerical results for regular and irregular waves are shown. Air-mass flow rate/air pressure characteristic of the air turbine, capture length, response amplitude operators, variances for relevant parameters related to device's behavior are computed.
