Summary
Two vessel hatch-lifting incidents caused equipment damage without personnel injury. Webbing strops failed in one lift, allowing the hatch to fall back onto the deck; hatch hinges failed in the other. Recommendations address systematic hatch reviews, risk assessment and lifting methods that account for loads remaining attached to the vessel.
