Ferry operator DFDS says they do not yet know what caused the incident. An investigation by DFDS Seaways and the Danish maritime authorities is underway.
The damage to the ship has been investigated, and there is some damage to the hull in the front of the ship and on the bulb, and unfortunately it could not, as they had hoped, be repaired in the port.
Therefore the ship has to go to a shipyard for repairs. Available dry dock capacity was found in Bremerhaven in Germany.
Once the repairs have been completed, they will then have to be approved for safe sailing before the ship can go back into service.
"We can confirm that, following the incident on June 22 involving Sirena Seaways as she entered the port at Harwich, sailings have currently been suspended on the Harwich-Esbjerg service while the ship is being repaired. The assessment of the damage to the ferry has revealed that it needs to be repaired in dry dock. As a result, it is likely that the vessel will be out of service until at least Saturday 29 June."
