Stability
Talking about stability, this ship, the Zhen Hua from Shanghai, entered Rotterdam last week. The voyage lasted 2 month, the 3 large cranes have a height off 127 meters.

There was a similar ship that came into Miami, not to long ago.

Wow! And I thought some of the recently launched mega-cruise-ships looked top-heavy!

There seems to be a lot of latitude on this Forum for just exactly what the word "trawler" means. But I'll just bet that we can all agree that these are not trawlers! :-)

Reiziger,
That's unbelievable. I wonder if they can shift the weight in some way? Doing that for a beam wind could promote some excitement if the wind died quickly. Paravanes?
jwnall,
After a year here you should know we have plenty of "latitude".
Speaking of latitude could you post a pic of your interesting avatar?
Can't make out much in the tiny thumbnail.

Are they delivering the cranes for use on land at a port or do they operate off of the ship?

I'd like to see them get the cranes on and off the ship. What do they use? A bigger crane?

I suppose they gain some stability in the same way a tight-rope walker does, with the long balancing pole. But they can't raise and lower these, so ?
It's hard to believe they make long voyages with these things on the deck!

I believe they are transporting the crans e from factory to a port which will use them on land it looks like they are rolled off onto the port area .

And sometimes it goes wrong, February 2nd. 2008 the "Zhen Hua 10" was beached on the beach of Hook of Holland in a 11 Beaufort gale with an average wave height of 7-8 meters.

Those Naval Architects earned their money with those crane transports. Looks like balancing a pencil point on a razor blade.

Craig, did you notice that it looked like they flooded the tanks to get under the Chesapeake Bay Bridge. I guess they can do that to adjust the height for loading and unloading.

I didn't click any of the links above but have been involved with enough "lifts" in my career to have a decent idea of what is possible Don. Adjusting ballast
at the dock is integral to loading and unloading as I imagine they are slid from dock to ship and back again. The only crane involved in the process would be used to adjust the dunnage. Once on the dock hydraulic jacks would most likely be doing any lifting and lowering is my best guess.
Big lifts are neat to participate in when done right. The planning and coordination of them are the most stressful part.

Didn't see that shot clearly earlier on my iPhone, wow! How would you like to be a spotter on top of the crane verifying bridge clearance prepping to go under the bridge? Talk about the pucker factor.

With all that gear, it looks like they could dig their own escape channel.
