I was running static equilibrium simulation (no wind, no wave) for OC3 Hywind and i obtained that the static equilibrium position is zero valued 6D vector. I was also thinking about how the structure will remain in equilibrium and there is an overhang due the RNA. For me, there is some applied moment to counteract the overhang moment. right ? This " restoring moment "is calculated automatically by MoorDyn or its added in order to force the structure to be in equilibrium at zero?
The pretension used in OC3 Hywind exists when using MoorDyn or just used when using the linearized mooring line stiffness model ?
