Slant-Leg Unit
Jack-up with legs that can be inclined at a significant angle to the vertical. NOTE The inclination angle is typically about 5°. The benefit is that the jack-up behaves more like a braced frame and less like a portal frame, with accompanying reductions in leg axial forces and moments.
