Big cranes
« on: March 04, 2013, 01:38:51 am »

I don't know if anyone else has posted on here, but does anyone fancy modelling this ship and 'cargo', that recently arrived on the Thames.
They say the cranes are higher than the London Eye.

London Eye..hmmm.   How many double-decker buses is that ? %)     Any more info on that crane, is it cargo coming ashore or does it stay on the ship ?   Must be fun on rough sea :(( .

I would imagine that the cranes are brought down to nearer deck level when at sea,
or is it just a harbor vessel?Has it got a rolling deck for stability?

I've passed plenty of these on the high seas enroute to Europe from China, and no, the booms are left as in the picture.  I have also seen them with the booms raised as you see them in port when not working!
As most of these carriers are converted tankers/bulkers, I can only assume they are suitably ballasted for stability, and their transits are weather routed.
 
Its interesting to see a port with cranes coming over the horizon in the middle of nowhere, only to see later they are a ship in transit.

I'm sure they've done their maths right, but it looks awfully wrong.

...hey, maybe they could save themselves a bob or two on fuel oil if they hung up a few acres of canvas?  {-)

In the first picture I thought that was just a ship parked next to a dock with cranes, Didn't realise they were on the ship until the next photo!


Makes you wonder how they get them off the ship, Another crane to lift the cranes off perhaps?  %)

That, just looks soooooooooooooo wrong, top heavy. Obviously it works, some very good workings out to keep that lot stable in rough seas.
Si:)

They jack them up a bit, turn the boogies through 90 degrees, and run them ashore on rails then reverse the process so they then run parallel to the quay on the rails.
All relies on perfect timing tides and ballasting to get the deck level with the dock!!

All very impressive I'm sure.
But what's the point in having the ships bridge placed in a position where it's worse than useless? That little "Crows nest" on the foc's'le might be OK for visual sighting......
Sorry, but I think the entire arrangement is just an "accident" waiting to happen. BY.

Probably a camera on the front end and a screen on the bridge.  I imagine that being able to actually maneuver without assistance at close quarters was never a real consideration.
