Suez Canal blocked by container ship 36

[verymadmac]

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



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

Thanks IRS... I'll have to sort that out...

After reading about the evergreen my news feed is giving me marine news...

Which to be honest is no bad thing

https://www.swzmaritime.nl/news/2021/04/06/smit-salvage-team-en-route-to-listing-eemslift-hendrika/

Load shift and rough weather. This time SMIT is off to save the day.

Didn't see the point of creating a new thread.

There are some old books about sailing on boats with actual coal bunkers. "Captain Jan" comes to mind where the experienced captains were able to feel the change in roll to know when the vessel was becoming dangerously unstable. Roll on Roll Off ships are notorious for getting their ballast wrong and ending up on their sides. I am surprised there is no accelerometer based system to alert crews their ship is not stable. In this case, seeing the way the ship rolls, it may be on its side but it's seems very stable. I can understand a crew evacuation because beds and dining tables don't work at such angles, stairs become quite challenging too. It doesn't appear that the ship itself is in danger, though. That's good design.

 

[Alistair_Heaton]

Some of the load came adrift and shifted. Which appparently made it unstable.

A big work boat is now a drift after falling off.

So it might have fixed itself.

The salvage crew getting airlifted in.

I suspect that's why they need an unlimited master on a salvage crew so they can take command and drive it to somewhere safer. ?

 

[epoxybot]

An old tug-boat captain once told me of his impression of tug design.
Select the engine and prop that will do the job.
Add enough boat to keep them from sinking.

Something like this...Link

Like an iceberg, mostly underwater.
This type was popular at the mills and booming grounds on the west coast of Canada.

Taken at the Duncan Logging Museum , Canada.

There is a prop in the cage (not shown in the photo) that may be rotated 360 degrees continuously.
There is no rudder, the boat moves in the direction that the prop is pointed.
The fixed skeg at the back turns the boat in the direction the prop is pulling it.
That is why the rolling action when the boat changes direction.
I understand that some models were driven by a V8 diesel with over 300 HP.

"A master mariner is a licensed mariner who holds the highest grade of seafarer qualification; namely, an unlimited master's license. Such a license is labelled unlimited because it has no limits on the tonnage, power, or geographic location of the vessel that the holder of the license is allowed to serve upon. A master mariner would therefore be allowed to serve as the master of a merchant ship of any size, of any type, operating anywhere in the world,[1] and it reflects the highest level of professional qualification amongst mariners and deck officers."

First I've heard the expression... thanks.

[Alistair_Heaton]

dik I believe it doesn't cover the great lakes with the standard one. You need some additional exams and tickets for them.

I only know that because of pub piss taking between two holders. The Scottish none Great Lakes skipper put forward the point that the Canadian who was qualified should get the beers in because he was more senior. He claimed it was against his religion because he was French Canadian.

 

[dik]

Could be... I'd never heard of a master mariner before this thread, or a Z-drive. You'd think that if he could pilot a boat anywhere in the world... the Great Lakes would be a walk in the park... same skills involved...

We have the equivalent in aircraft

Airline Transport pilot license ATPL.

But we have to be qualified on a type.

There are very rare pilots out there which are the equivalent to unlimited in regards they don't need rated on the aircraft. But they are restricted to none public transport and geographical area that the qualification was issued in. They are part of the test pilot certification setup so you don't often meet them. I have flown with one twice in 17 years.

 

[Alistair_Heaton]

The unlimited I have met seem to cover the full range of autocratic arsehole through to hairy bummed pirate.

But it's the same in the aviation world as well.

[FacEngrPE]

The special license for the great lakes makes some sense, just from physics. The water is fresh, so any ship will sit lower in the water than it would in brackish or salt water. This changes the dynamics of the ship's buoyancy. The great lakes are also known for some seriously rough weather. The largest tonnage transported in the great lakes for years was taconite. Ore carriers by design sit very low in the water, which when combined with heavy seas creates additional challenges for ship handling.

What caused "The Wreck of the Edmund Fitzgerald?"

 

[Alistair_Heaton]

I suspect its a law exam addition. But didn't ask.

 

[waross]

FacEngrPE, Thanks for the new information in regards to the Edmund Fitzgerald.

"Ore carriers by design sit very low in the water,"
Someone thought the Great Lakes were saltwater?

 

[JohnRBaker]

My favorite Aunt (by marriage), her father was a Scottish sea Captain who, when he finally retired, was sailing the Great Lakes out of Sandusky, Ohio. And my boss, when I got my first job as an engineer, had been, before he went to engineering school, an able bodied seaman who worked the Great Lakes during the summer and the Gulf of Mexico during the winter. He was half Native American, a member of the Chippewa Nation in the UP of Michigan and back in the early 50's there weren't that many good jobs for young Indian boys so working the lakes was a good opportunity. He was eventually drafted due to the Korean War and while he could have gotten a deferment because being a able bodied seaman was an exempted occupation, he opted for the Army anyway as it allowed him to later go to engineering school on the GI Bill. He was a good boss, but the joke around the office was that he tended to swear like a sailor ;-)
