A passenger ferry collided with a cargo vessel at the entrance to Belfast Lough yesterday evening.
The Stena ferry has 51 passengers and 47 crew on board but there are no reports of any injuries.
According to the Press Association, the ferry has now docked at its terminal in Belfast.
The incident happened about a mile and a half from the coastline between Carrickfergus and Helen’s Bay.
Police and the Maritime and Coastguard agency have launched an investigation into the incident.
The ferry was on its way from Birkenhead, Merseyside, to Belfast when the incident happened.
BBC reports said passengers heard a "massive bang" before the emergency sirens went off and they were issued with life jackets.
