A few Engineering shots for the Boys

[krusty]

I've been out to the Platform this morning (I'm GMT +4) to check on a few things today and took a couple of shots of the legs. Three legs in total that lift this 30k Tonne TPG (floating platform) out of the water once we're on site. The legs are about 120m long and jack the platform 15m out of the water
It's amazing how smooth the lifting operation is. The jacks don't even break into a sweat.

nice photos

I've got vertigo already...

Now THAT is a rack (no pinion... )

There was a jack up dry towed around the Cape of Good Hope a few months ago, has similar cracks in the legs.... suffice to say they fell off when in the southern ocean with all the motion induced stresses

How do they make those big racks?

Great engineering photos,along the same lines here is a pic with a Ship (Blue Martin) carrying the 40,000 ton rig on its back,incredible that they had to balance such a huge structure to within 10cm's and then carry it half way around the world.

I bet there were gangs of pikey scrapmen waiting just outside H&W gates in case it fell off...

They're cut from plate and then the two half pipes are welded either side

Nice pics, seriously big kit.

I used to work on these (jackets) at Ardersier in Scotland, the scale of engineering is amazing. While I was there the company (McDermotts Oceanic) had just commissioned the largest crane in the world, Lloyds had just signed it off when it blew over destroying itself in about 5 seconds.

Thunder Horse platform in the Gulf of Mexico, largest PDQ ever. A very very impressive piece of kit: worth a read www.bp.com/genericarticle.do?categoryId=9002799&contentId=7005415

Was it blue?

Amazing - some seriously heavy duty metalwork there. Excellent pics...!

Good thread.

I like the pics ZR1cliff posted, it amazing the load that that ship carried!.

Sure is!

The pictures in the article of how they moved it to the destination are amazing

Firstly I believe Thunder Horse was one of the platforms badly damaged during hurricane Katrina. It was moored up for commisioning, broke the moorings and ended up wedged under an overpass.
Here's a few more pics for you

can't remember the colour but it was an H shaped double jib built on a walking square frame. It was supposed to be parked facing into the wind with both blocks anchored onto enormous weights, someone thought they'd get away with one, the wind caught it and 600 ft or so all fell into a neat pile of scrap within the square of the base.......apart from one of the 25 ton blocks which buried the drivers car.

The cranes in Ardersier were Lampsons.

Thunder Horse almost sank in the wake of a hurricane.

The one that got stuck under a bridge was a drill rig in Mobile docks - broke its moorings.
