Navigator of the Seas has been given the all-clear to leave Vigo, Spain, after an unscheduled overnight stop for repairs and inspection.
The ship reportedly suffered a mechanical issue involving one of its stabilisers.
A Royal Caribbean spokesman said: "We have now addressed the issue and received all necessary clearances and approvals to resume our itinerary safely and comfortably."
On Sunday, the cruise line issued a statement saying: "Navigator of the Seas is making repairs to resolve a technical issue.
"The ship is fully operational with no impact on its maneuverability or the safety of our guests and crew. However, because of time needed to make the repair, it was necessary to modify her current itinerary."
Navigator of the Seas will sail to Gran Canaria and Tenerife before returning to Southampton as scheduled on November 5.
