On June 16, 2019, about 1322 local time, the bulk liquid cargo vessel Dank Silver was transiting downbound on the Mississippi River, near Donaldsonville, Louisiana, when it struck the fender of the western pier to the main (channel) span of the Sunshine Bridge. No pollution or injuries to the 19 crewmembers on board the Dank Silver were reported. Damage to the vessel was about $1.05 million, and damage to the bridge was estimated at $3.5 million.
The National Transportation Safety Board determines that the probable cause of the tank vessel Dank Silver’s contact with the Sunshine Bridge was the pilot’s decision to turn the vessel off the dock instead of going upriver to gain sufficient steerageway to maneuver downriver through the bridge.
I thought this was interesting as we had just discussed strength of ship’s bitts and chocks
