1st and 2nd order wave loads on floaters calculated from wave load RAOs and QTFs Technical Spec OrcaFlex version 9.2 Summary of key features: ✯ Best of class fully interactive GUI DATA INPUT. Fluid forces based on industry-standard Morison and cross-flow assumptions. Facilities for FFT re-construction of wave field from single point elevation time history. Slow varying water particle loads can be computed at a larger time step than structural displacements. Parallel processing to take advantage of modern multi-core and multi-processor hardware. Choice of implicit or explicit time integration methods. Element formulation is extremely robust, accurate and widely applicable. Finite element with 6 degrees of freedom at each end. Line setup wizard to set line lengths for specified tension or top angle NUMERICAL PROCEDURES. Vessel manoeuvres (forward speed and turn rate). Fully coupled tension, bending and torsion. Fatigue analysis (regular, rainflow & spectral). Contact, clashing and clearance analyses. 
Non-linear large displacement analysis, including line compression and snatch loads. Time domain dynamic analysis with ramp-up (to minimise starting transients).
