Marine Investigation Report: Crane Wire Failure on Cargo Ship Thorco Basilisk, July 26, 2022

On July 23, 2022, about 1440 local time, the cargo ship Thorco Basilisk was discharging cargo at the Greensport Terminal on the Houston Ship Channel in Houston, Texas. While off-loading a wind turbine component, the hoisting wire rope on a shipboard crane failed, causing the component to drop onto the vessel’s cargo hold tween deck. No pollution or injuries were reported. Damages to the ship and the component were estimated at $3–5 million. The National Transportation Safety Board (NTSB) determined that the probable cause of the failure of the hoisting wire on the cargo ship Thorco Basilisk’s crane was undetected corrosion and wear in strand wires.​
