- Ships large navigating the canal normally do so through pilots specialized in it provided by whoever operates the canal. And while the captain still is in control he/she delegates the control to this pilots under his/here supervision (as they are still responsible for the ship I think). So even if the captain is responsible he/she wasn't "really" navigating the ship...
- There was a unusual large sand storm, it is possible that things had been 100% outside of the control of anyone navigating the ship. Just consider a causality chain like sand-storm => engine failure(cause by it) => wind drives ship onto shore before restart of engines is possible.
So it's completely pointless to name anyone human involved until the actual causality chain is properly investigates.
A thing which tbh. should be done much more in other cases, too.
