Another Carnival Cruise Ship, Another Electrical Systems Failure

Though you'll be reading about this latest problem with cruise ship electrical systems for many days to come, I thought I'd provide a very brief advance reference to it. Another giant Carnival ship, the  Dream , carrying 4,000 passengers plus heaven-knows how many in crew, is currently experiencing a sharp reduction in its electrical power, causing toilets and elevators to stop working. But this time, luckily, all this has occurred not while the ship was at sea but safely docked in Philipsburg, St. Maarten.
After a single day of experiencing these outages, passengers have been advised they will now be flown back to the States by specially-chartered airplanes or on scheduled flights. It is not known how long they will have to wait for a flight home. And obviously, during high season, the hotel resorts of St. Maarten are unable to accommodate these 4,000-some-odd guests. So a great many Carnival passengers will be stranded in great discomfort until given the notice that a plane awaits them at the airport of St. Maarten.
Passengers will be given a refund for three days of cruising, and a 50% discount off a future Carnival sailing.
What's to conclude from all this? It's obvious that in the same way that Boeing executives failed to think through all the problems that might afflect electrical batteries placed aboard their latest aircraft, it should now be crystal clear that cruise ship executives have been rushing to complete one 4,000-passenger gigantic cruise ship after another without thinking through the need for full-scale alternative sources of power if something should happen to the main generators.
A cruise ship is like a self-contained city. Its thousands of guests are wholly dependent on the proper working of an electrical generating system. And since such systems are not always capable of working 100%, there obviously should be back-up systems in place. It is simply a mystery of how a cruiseline could take on the responsibility for 4,000 passengers, without being absolutely certain that working toilets would always be available for them. The current problem is the third such episode to be experienced by Carnival. And that's something that would-be passengers should think about.
Sorry to have spoiled your day.
