The drama started with the grounding of a containership on July 15, which has been identified as Aeneas.
The 63,059 dwt containership grounded during its transit at about 1830 hours local time, GAC Egypt reported.
It was the 20th in the Southbound convoy of 27 vessels. Initial reports indicate that the ship suffered an engine failure that led to the grounding.
The three bulkers that followed in the convoy failed to react in time and collided.
