A 51-year-old man fell overboard on a Norwegian cruise ship in the Caribbean, hoping to find it abandoned after an “extensive” search, the cruise company said.

The unidentified passenger fell from the Norwegian Epic around 3 p.m. Thursday while the ship was traveling from Ocho Rios, Jamaica, to Great Stirrup Cay in the Bahamas.

“Authorities were immediately notified and a search and rescue operation was initiated under the direction and supervision of the Bahamas Rescue Coordination Center,” a spokesperson for Norwegian Cruise Line told The Post.

After an “extensive” but ultimately unsuccessful search that required the help of another nearby cruise ship, the Norwegian Epic ““The authorities have cleared us to continue the journey,” the cruise company said.

It was not immediately clear how the passenger fell overboard. He was traveling with a large group that included his family, who are “being cared for and supported in this very challenging situation,” the cruise line said.

“Our thoughts and prayers are with his loved ones during this difficult time,” the spokesman said.

Immediately after the passenger fell overboard, the ship dropped a flare into the sea to mark the spot where the man fell and circled the area repeatedly, according to Cruise Hive.

The Holland America Line ship Zuiderdam, which was sailing nearby, took part in the search.

Video posted on social media by a passenger on the Norwegian Epic shows passengers on their balconies scanning the sea for signs of the man.

The Norwegian Epic is currently on a seven-day Caribbean voyage after departing Canaveral, Florida, on Saturday.
