Cruise Ship Loses Power, Goes Adrift Near Canary Islands

That is what I meant to say, under these conditions the passengers were in danger but the company stated that they were never in any danger.

The PR departments are not responsible of driving the ships, but to remove negative impressions from potential clients.
The coming investigation by the Spanish or British authorities will certainly not ask the PR folks.

The still functioning bow thrusters were probably declared as “to take care of emergencies” by PR too.

The reason for the loss of propulsion will hopefully be known with the investigation report…

It is probably possible to change the direction the ship is drifting to some degree by changing the ship’s heading. Changing the wind from the beam to the quarter might alter the resultant motion vector from the beam to slightly forward of the beam.

That’s my observation from drifting when the swell changes the relative wind direction from abeam.

Yes, I thought about that too, these cruise ships having a huge ‘sail area’.

However, I could not imagine how realistic this would be in 20 knots of wind and a weight of 60000+ tons.

Big boat, possibly, bow and stern thrusters?
If so at least it could go sideways?

Thrusters are not usually on emergency power.
Diesel Electric with shafts, at least some of the main power supply was still operating.

So no power to the electric motors.
If it was a motor issue, surprising to affect both.
Power supply is very high voltage, could condensation affect this?. Would there be a common supply?

There’s got to be some pretty sckookum breakers? Possible a single tie breaker for both main shafts?
I bet they don’t have those on the shelf down at Home Depot.

20 knot winds, no idea what the operating parameters are, Ports here tend to use 25 knots. Varies with the power.

Well yes. My actual high tension experience is nil, but I’d expect one of those systems to be set up so that the merest idea of a ground leak makes it go dark. If we’re talking about an electrical component not on the engine, this makes a lot more sense.

The speed of drifting depends upon the ratio between the cross-section area below the waterline and the sail area above. A loaded tanker will be less effected by the wind than one in ballast. A car ship or cruise ships more so than a tanker.

For every ten knots of wind a car ship will drift at about 1 kt.

Diesel engines use to be highly reliable because they did not have any electronics.

Now Diesel engines are becoming highly unreliable because they are too dependent on sensitive electronics.


In my limited experience of high current and high voltage installations the buses separated in an emergency with a small explosive device. I think you would likely enjoy a long conversation with law enforcement authorities if you enquired for them at Home Depot.
