The aero-servo-hydro-elastic Finite-Element-Method code 3DFloat is tailored for nonlinear, coupled time-domain simulations of offshore structures in general and offshore wind turbines in particular. This article describes the theory behind the structural model, aerodynamic and hydrodynamic load modules, control system and coupling with an optimizer. The verification and validation history includes the IEA OC3/OC4/OC5 projects, two wave tank tests and participation in commercial projects.
