🏗️ Offshore Lift: Ship Heave, Dynamic Amplification and Snatch Load (2D)

Side view of an installation vessel heaving on a regular wave with a crane holding a heavy payload on a steel rope that acts as a spring. Set the sea state, the vessel heave period, the payload, rope length and diameter, damping and hoist speed, and see the rope tension, the dynamic amplification, a slack rope in rough seas, the snatch load at pick-up and the safety factor against the rope breaking load. Ship response, rest tension, amplification and snatch are checked numerically, with four in-page numerical checks.
