'In an abundance of caution, we made the decision that the safest and most prudent action was for Celebrity Summit to return to port to assess the situation,' Celebrity Cruises said in a statement.
'Our on-board team worked on the issue and the ship departed Cape Liberty at 4 a.m. on Monday. Even with the later departure, the ship’s original itinerary will not be affected.'
Celebrity Summit's seven-night cruise includes three nights at Kings Wharf, Bermuda.
