repairs to the Azipod units. During the refit, maintenance was performed on its bow thrusters and stabilizers, as well as the Azipod units, ballast and bilge piping were replaced, a low-resistance silicone paint aimed at increasing fuel efficiency was applied to the hull, and the release mechanisms for the lifeboat tenders were upgraded. The Norwegian Star'''s dining and entertainment spaces were also renovated and digital signage, first introduced on the Norwegian Breakaway, was installed. Norwegian Star underwent a refurbishment in summer 2018 during which it received the Sky High Bar (which replaced the Bier Garten), the Bliss Ultra Lounge (which replaced Spinnaker Lounge) and the adults-only Spice H2O. Additionally, all cabins and suites were outfitted with USB charging ports. Accidents and incidents Azipod problems Damage to the forward thrust bearing in Norwegian Stars Azipod system in April 2004 caused the suspension of trips to Fanning Island, Kiribati. Because of the damage, the ship was restricted to instead of the needed to make the journey around Hawaii and to Kiribati in the week allotted for the cruise. The stopovers in Kiribati were required under the Passenger Vessel Services Act of 1886 whereby non-U.S. flagged ships are prohibited from departing and returning to a U.S. port without first calling at a foreign port. The penalties associated with skipping a foreign port were waived for NCL on account of the damage. A revised itinerary with stops in Kailua and Lahaina was substituted until the end of April, and the repositioning cruise to Vancouver was cancelled to allow Norwegian Star to go into drydock early. Additional problems with the Azipods forced NCL take the Norwegian Star out-of-service for two weeks in April 2015, and cancel its repositioning cruise through the Panama Canal. In December 2016, problems with one of the Azipods delayed the Norwegian Stars departure from Singapore and forced the curtailing of additional itineraries. Azipod failures occurred again in January 2017 between Singapore and Bali, leading to further itinerary changes and then in February 2017, when the ship's Azipods failed off the coast of Victoria, Australia requiring it to be towed to Melbourne. New York City docking incidents On 27 April 2012, Norwegian Star struck the pier where the aircraft carrier , the centerpiece of the Intrepid Sea, Air & Space Museum, was docked while she attempted to dock at the nearby New York Passenger Ship Terminal in Manhattan.
