Two huge Hapag-Lloyd and Maersk Line container vessels collided in the Suez Canal on Monday morning.
The German owner said there was an impact between its 8,749-teu Colombo Express (built 2005) and the 8,112-teu Maersk Tanjong (built 2007) at Port Said.
The Hapag-Lloyd ship was entering the Canal at the time, it added.
No injuries or pollution have been reported.
Ship agent Inchcape Shipping Services said Maersk Tanjong was clearing the Suez Canal Container terminal to join a convoy.
Three containers have fallen from Colombo Express and the vessel has a 20-metre dent to its left side.
Some delays are expected for other traffic as a result.
Inchcape added: “The Suez Canal Authority is currently trying to pick up the dropped containers from the eastern channel and both vessels will be moored at the canal lakes until the required investigations, paper work and maintenance have been completed.”
Hapag-Lloyd said both vessels are able to continue on their voyages.
It added: “The exact course of events is currently being investigated.”
