All six generators are connected to a common "bus" or switchboard, that supplies every electrical need on the ship, whether propulsion or hotel. The various sized generators allow for combining them on line in various configurations to allow for maximizing the load on the generators at various operating conditions. For instance, you could use the two smaller Wartsila engines if the ship is steaming at slow speed, or one large and one small for higher speeds, and finally all four Wartsila engines for full speed. The two CAT generators are "emergency" in that they can be used in a situation like the Carnival Triumph, where the engine rooms were disabled. They can also be used to augment power when one Wartsila engine is down for maintenance, though not fully, of course. 26 minutes ago, ew101 said: I think I would feel safer on a ship with azipods turning in a fast current docking on a river vs one with fixed shafts. A modern cruise ship with bow and stern thrusters, two shafted controllable pitch propellers, and two "high lift" rudders, with the proper training can be just as maneuverable as an azipod equipped ship, in a docking maneuver. As well, if an azipod goes down, you lose not only propulsion, but steering as well, while with propellers/rudders, losing one system does not take down the other. The major advantage of azipods over conventional propellers/rudders is initial capital cost. Edited December 25, 2022 by chengkp75 2 Link to comment Share on other sites More sharing options...

spizza Posted January 1, 2023 #53 Share Posted January 1, 2023 When the captain came over the intercom to give us the bad news on missing 2 ports, he specifically said “ we have been in contact with ABB to try to resolve the issue” must have been an azipod issue. Also only 1 propellor wash was visible for the remainder of the return trip. 1 2 Link to comment Share on other sites More sharing options...
Chiliburn Posted January 1, 2023 #54 Share Posted January 1, 2023 Quantum has missed Mystery Island again today. Mystery island is the highlight of the pacific . Between Ovation and Quantum I think there has only been one successful visit this season. I wonder if somehow it’s connected to Lelepa? Link to comment Share on other sites More sharing options...

Thank you for the consistent updates which may lead to a reason for so many many missed Mystery Island port calls. 1 Link to comment Share on other sites More sharing options...
