Back in the day (2009), Stephen King was providing support to a customer who was involved in investigating the damage caused to a single-skinned, Greek-owned oil tanker, the Athos 1. The ship had been in the process of docking at an oil terminal on the Delaware River, USA, when the hull was punctured by an old anchor that had been left on the river bed that unfortunately, led to the second worst oil spill in USA history at the time.



A FEA Abaqus simulation was produced that resulted in the included animation. The location and extent of the tear and puncture holes were remarkably close to that witnessed. The ship makes contact with the tip of the fluke which results in a tear in the hull and a rotation of the anchor on the riverbed. This rotation then causes the palm of the anchor to puncture the hull a little way from the tear. The animation shows the general process as well as a view from inside the hull as the damage occurs. An image of the damage from the outside taken when the ship was in dry dock is included in the animation.
