On November 30, 2018, while navigating south of Yemen, Marella Discovery experienced power problems, resulting in reduced cruising speed and a day late arrival in Port Muscat (Oman). In Port Dubai (UAE), the vessel remained docked for 2 days (waiting for parts and undergoing repairs).
The accident occurred during the 14-day Aqaba to Dubai itinerary (Nov 22 - Dec 6) visiting Muscat Oman (scheduled for Nov 29-30 / overnight), Khasab Oman, Mina Salman (Bahrain), Abu Dhabi, Sir Bani Yas Island, and Dubai.
The next scheduled 14-day voyage (December 6-20) from Dubai to Pulau Langkawi Island was also affected as the ship has to leave Dubai on Dec 7 (at 3 pm). The list of scheduled for calls ports included Mumbai India, Mormugao-Goa India, Mangalore India, Cochin India, Colombo (Sri Lanka), Pulau Weh Island (Indonesia) and Phuket Thailand, to Pulau Langkawi (Malaysia).
In the revised itinerary were dropped / cancelled Mumbai (replaced with 3 sea days) and Mangalore (replaced with 1 sea day). The other call ports remained as planned.
On its web page the TUI company apologized to its clients, saying that they had experienced a technical issue with the electrical systems in the early hours of Wednesday, November 28, 2018 and were able to continue safely to Dubai for maintenance at a slower speed. At present, they were still "working through final safety checks and repairs, and we will be able to set sail for India on Friday as planned, but again at a slightly reduced speed."
