A tourist has reported that an emergency situation has arisen on a cruise ship following a “passenger overboard” incident.

Travelers aboard the Norwegian Jewel—currently voyaging from Barcelona to Miami—recount being awakened at 2 a.m. by the announcement of “code Oscar starboard” over the ship’s intercom. This is a maritime alert indicating a person has fallen overboard.

According to a passenger, the crew confirmed that an individual had indeed “gone overboard,” prompting the ship to enter “search and rescue mode” as it navigates the Atlantic Ocean in circles.

The Norwegian Jewel embarked on its journey from Barcelona on October 15.

A British traveler, who prefers to stay anonymous, recounted, “I was asleep in the cabin. The captain announced ‘code Oscar starboard.’”

“As it was transmitted into our rooms also. I thought it might be serious and googled it to find that Oscar means person overboard.

“We have just in the last 10 minutes had an announcement to confirm someone is overboard, and that is why we have been and still are circling.”

Norwegian Cruise Line has been contacted for a comment.
