A total of 13 fire appliances, 61 firefighters and a specialist marine response team were called to a blaze on a ferry in Belfast port on Sunday morning.
The Northern Ireland Fire and Rescue Service said the fire on the Stena Line ferry at the Victoria Terminal on West Bank Road was reported just after 5am.
A spokesman for Stena Line said a small fire in the exhaust system of the Stena Superfast VII vessel had broken out while the ship was in port in Belfast.
“It was quickly brought under control by trained Stena Line crew but in line with established safety procedures, the emergency services were alerted as a precaution.
