Brand new worlds largest floating crane failure.

I suspect design was just as much a problem - and it was a Liebherr!

Libherr build some proper crap occasionally

I dont think the hook broke, looking at the pics it looks like the hooks swivel housing has failed.

This may sound harsh, but in some oil industry office, folk will not be unhappy about that mishap. It looks like a heavy lift support ship, for lifting in big subsea modules offshore, but as prices are so low, deep water subsea stuff isnt good economics at the moment.
It will have been pre booked, so the dealys will mean some poor names at Lloyds insurance will end up paying out. And liquidated damages for delays paid others too.

And no matter how many layers of protection you put in place, failures still seem to happen, just the outcomes are not as severe as they were in victorian times.

She was to go on a job in Scotland, not oil related wind farm job!

Offshore cranes are rubbish, better with Huismann..

Think they need some ductape

Although every time I've worked in Germany, they still seem to think the UK are = that "Made in Great Britain" still MEANS something.

Made in Great Britain still does mean something if you can find it.
The few remaining machine tools made here are world class, bae etc etc
Now Britain’s production workers(non skilled) are dreadful

 

[Seadog]

What they needed was this

 

[Munkul]

That's a valid point. Surely they would have had proof test loads on that hook assembly BEFORE it went near the crane?

A preserved steam railway in Estonia paid a lot of money for German certified steam boiler tubes when they rebuilt a boiler, did not want Chinese, the tubes failed after 3 or 4 years, when tested they were found to be way under spec. and 99% likely Chinese but supplied with German paperwork from a German supplier...………………….. the case is ongoing.

Very very common occurrence

BAE is a joke. There’s a reason every sub is overdue and over budget.
You’ve got very very clever people, surrounded by muppets. Some of the best welders around, tied down by ridiculous rules and regulations.
I’m sure I’ve put this on here before but some time ago, they did a study at BAE.
The guys would get to work, sign out their welding consumables, by the time they got setup and welding, they done about 20m - half hour and it was tea time. Then they had to sign out fresh consumables again, then it was lunchtime, etc etc.
Everyday for two men, 3 hours of welding got done!

First thing anyone can see it that video is that it has been edited to remove the moment of the actual failing component. One assumes part of the hook assembly. A quick google suggests there will be a TON of fake news/spin being put out by all concerned to try and cast doubt on anything other than the hook failing.

Disinformation is now routinely used by global industries and of course state sponsored propaganda machines. Be interesting to see if/when the full video emerges.

It still means a hell of a lot in the right environment.

I remember a documentary that was sparked by I think Top Gear's feature on vehicles made in the UK. It was about whether manufacturing was dead in the UK and the outcome was "industrial" manufacturing was but you actually found most of the high end manufacturing in the world was still done here. I can't remember the exact race series but I think it was all the Indie 500 cars are controlled by McLaren ECUs, most of the F1 teams are based in Oxfordshire / Bedfordshire. Then you have the stuff like, as you say BAE - did you know that they designed the first ever MEMs accelerometer and about 80% of vehicles worldwide use their design for the crash sensors etc?

I do remember a talk with a foreign client when where they had a directive that they should source systems in-country rather than delegate matters of national security to a foreign entity (the UK). The response to their bosses was, fine we can do that, but we'll be going back 10 years. The response from on-high was that was unacceptable and they must have in-country technology and people to be better than the UK. To which they replied, we simply don't have the skills that the UK have - they are decades in front of us (this was small scale but high-end electronics design and manufacturing).

The main hook block failed at around 2000t, whilst load testing. It's a 5000t crane. Happened yesterday.View attachment 227940 View attachment 227941

They make a pill for that

I’m not interested in welders and those organising production. I’m interested in the avionics division.
I rebuilt a studer grinder for them for their gauge department and they demanded tolerances you couldn’t pronounce !

 

[sako243]

Produce or pronounce?

Reminds me of the guy at Cosworth when Adrian Newey told them to build the Valkyrie engine, said it had to be 1000hp N/A and 200kg. Got the power but only managed 203kg. He said if they'd been asked to make it 210kg they would have stopped at 210kg. As it was Newey knew 200kg was probably unobtainable but by specifying it they got it as light as possible.

Same lousy, stupid, egotistical management though! Still passing the buck downwards.

I would guess at some lousy planning and project management, especially the test and specifications and then being rushed or omitted due to time or contract pressures.

Meh. My money is on a materials failure. Can't blame the computers, they never make mistakes. Can't believe a designer could get it wrong. It is possible that the swivel assembly (?) might have been installed incorrectly but that seems unlikely. Most likely is a failed component due to manufacturing error. A flaw in a forged/machined component and to the sheer scale of the thing hiding a defect.
