A fire broke which broke out on a Stena Line ferry travelling from Wexford to Pembrokeshire had led to the scrambling of emergency services.
Life jackets were worn by passengers on board the Stena Europe which was sailing from Rosslare to Fishguard on Saturday night.
The crew of the 1,400 passenger ferry which has been on the Ireland-Wales route since 2002, were able to extinguish a blaze which took place in the engine room said HM Coastguard.
The ferry operator said all 88 passengers and 59 crew were unharmed and got off safely, and the Stena Europe has been taken out of service during an investigation.
According to a passenger, Stephen Kearney, said people were "understandably nervous but very calm".
"There was an announcement to the crew, advising it was not a drill and they should take up positions," he said.
"Smoke began to circulate and I could see smoke from the funnel".
"Life jackets were issued and crew members assisted passengers with life jackets," he added.
