Wind-related damage is a threat to most dockside cranes. Typically, damage is localized, but occasionally cranes collapse. Recent crane collapses have been caused by hurricane winds, usually when tie-downs fail, and by lesser winds under operating conditions.
We propose incorporating “ductile link” equalization into tie-down systems as a retrofit method for existing cranes in high-wind areas. We use an economy vs. risk approach to evaluate the need to retrofit existing cranes.
