SIMA

SIMA (Advanced Analyses of Marine Operations and Floating Systems) suited for complicated coupled simulations. The aerodynamics of SIMA is developed in MARINTEK and implemented gradually during the past decade to make it possible for enhanced coupled analysis of offshore wind turbine, both bottom-fixed and floating.

SIMA performs coupled analysis using the Simo and Riflex. This includes
• Nonlinear time domain simulation - combined wave, wind and current loads
• Wind generated forces on rotor using the Blade Element Momentum (BEM) method
• Control of blade pitch adjustment and power take-off control
• Aero-elastic rotor and tower (nonlinear FEM)
• Hydro-elastic floater, mooring lines and power cable (nonlinear FEM)

See the attached document for more details.
