On 22 June 2013, the ferry Sirena Seaways made heavy contact with berth 3 at Harwich International Port. The impact caused considerable damage to the fore-end of the vessel, including penetrations below the waterline. The linkspan at berth 3 collapsed into the water; the supporting structures were severely damaged and were no longer useable. Sirena Seaways was subsequently moved to another berth to disembark the passengers and vehicles.
No defects were found with the propulsion control systems. It was considered most likely that the button to activate the back-up control system for the starboard propulsion system was inadvertently pressed during the early stages of the entry into the port.
Recommendations have been made to the vessel’s owner.
