Suez Canal blocked by container ship 36

It might not be an engineering issue that started it, but I bet is going to change a few specifications.

It looks like the bow is hard aground, refloating will be an interesting exercise given the time pressure.

And when the lake doesn't freeze over, that's when they break snowfall records. Unfortunately, they've had a very mild Winter so far with just over 131 inches of snow (this is at the school in Houghton):

The year I graduated, 1971, that winter, while we didn't set a record for total snowfall (but we did get nearly 280 inches), we did set one for the longest continuous snowfall, 52 days. Now that does not mean that it actually snowed continuously, just that it snowed a legally measurable amount in a 24 hour period, every day, for 52 days. It was like living in the tropic, except instead of getting a heavy rain shower every afternoon, we'd wake-up every morning to two or three inches a fresh snow.

Now I say 'legally measurable amount' because in the state of Michigan they allocate additional highway funds for snow removal based on the number of days in which a county had a 'legally measurable amount' of snow, so keeping an accurate record of stuff like that can mean big bucks for the local county road commission.

More humidity from the unfrozen surface = more snow. Most houses in Calumet and Laurium have entrances on the second floor for winter access.

Seems there was a bit of fake news about who was the pilot.

Fair winds young lady for your upcoming exams. The guys that I know that have taken them say they are not easy or a tick in a box. .

A key one for me is that the ship in front which was reckoned to be about as big didn't have any issues with the wind...

This article I posted an excerpt from a few days ago stated that the two ships in front of the Ever Given had tug escorts.

I found these posted elsewhere but don't know what app or website generated them.

That looks like the Ventusky app.

https://www.ventusky.com/

AFAICT (I use it as my main weather app) it doesn't let you view historical data.

The icon in the upper right (showing wind speed) notes that those particular screenshots are from the DWD ICON model:

https://www.ventusky.com/?p=29.963;32.572;10&l=gust&t=20210325/1200&m=icon

So I'm not certain, but I think that data is ICON's historical prediction, not actual wind speed data.

Is that ever a neat site... thanks.

It really is.

Question. On

https://www.ventusky.com/,

wind gusts are reported as Maximum 1 hour.

The usual definition is

https://graphical.weather.gov/definitions/defineWindGust.html[/URL]]Is a sudden, brief increase in speed of the wind. According to U.S. weather observing practice, gusts are reported when the peak wind speed reaches at least 16 knots and the variation in wind speed between the peaks and lulls is at least 9 knots. The duration of a gust is usually less than 20 seconds.

If they are meaning sustained wind for 1 hour, that has a much more significant impact on the ship maneuvering, than the 20 second gust.
Increments on the time slider are 3 hours.

 

[RedSnake]

I found this historic weather report from Suez,.
If the Ever Given was going 13,5 knots against 5,94 knots north-northwest winds the actual speed was 7,56 knots or ??

Ever Givens speed 13.5 knots________Speed limit Suez 14 km/h ___________Wind 11 km/h________________________Wind gusts 15 km/h

Your getting confused with your aircraft stuff.

The ships reference is the water not the air. But they will take it against the ground reference. All the speeds on the AIS will be ground speed off GPS.

If the tide was pulling water north then that would decrease its ground speed and south it would decrease it.

The rudder authority is determined by the speed through water.

 

[RedSnake]

Thanks Alistair.
Your right I am confused
Well I guess that was to exact to be true.

You mean.
SOG, 10, Speed over ground, in 1/10 knot steps (0-102.2 knots) 1 023 = not available, 1 022 = 102.2 knots or higher.

If there hade been no wind at all and he hade been following the rules he hade been going 7,56 knots now it seems that he added the wind speed that he was going against 5,94 knots ending up at 13,5 knots.
Just coincident or is there some logic in that?

Best regards A

[Alistair_Heaton]

Ships you have to work with water speed to get the speed over ground not wind. Because the ship travels through the water

 

[dik]

We noticed that the ground speed was 0...

:-( Depends on your reference. ;-)
Standing on the moon it's not zero.

And that the wind does not come into the equation is true, as long as it isn't a Clipper Ship like the Maltese Falcon. ;-)
