“On the evening of December 10, while departing the port of Singapore, Norwegian Star experienced a technical issue with one of the ship’s azipods”, said the company operator in official statement. “The ship has returned to port so that the azipod can be inspected further by a team from the manufacturer”, adds the statement.

Norwegian Cruise Line informed the passengers about the route changes and also made very sumptuous compensation offers, as the guests will get their entire travel price reimbursed and a 50% voucher for the next cruise."
