I believe the dry dock ship already exists, though it may not be in the Bahamas right now. 1 Link to comment Share on other sites More sharing options...

I have to chuckle over Carnival's announcement of this being a "first of its kind" operation, when heavy lift ships have been around for decades, having carried offshore oil rigs and platforms, and damaged vessels like the USS Cole and USS Fitzgerald. This is essentially a self-propelled floating drydock, just as if you added propulsion to any of the floating drydocks already at Grand Bahamas Shipyard. Boka Vanguard (formerly Dockwise Vanguard), which was considered at one time for moving the Concordia from Giglio to the scrapyard, is currently on its way to the Bahamas, I believe estimating arrival later today. 1 1 Link to comment Share on other sites More sharing options...

Does the Vanguard have the ability to lift Oasis class ships? Link to comment Share on other sites More sharing options...
Milwaukee Eight Posted July 5, 2019 #2007 Share Posted July 5, 2019 (edited) Well, at least it’s real. Just all the pictures we see posted here are not. Maybe we’ll get some real photos. Edited July 5, 2019 by Milwaukee Eight Link to comment Share on other sites More sharing options...

Marinetraffic shows Vanguard about 10 miles from Freeport. Vanguard's deadweight (the amount of weight she can lift) is 110,000 tons, and I've only seen estimates of Oasis' displacement at 100,000 tons, so it might be tight. Given the open bow, stern, and the extreme beam of Vanguard, they could easily fit Oasis in there, they routinely have cargo overhanging, but it would be the weight that would be close. Here is an article about heavy lift ships, with photos of loads: https://www.amusingplanet.com/2012/05/heavy-lift-ships-and-their-impossibly.html Now that I think on it, there may be an additional problem with Oasis, that she is so long, the forward part would be overhanging a lot, and without support this could bend the ship. Even centered on Vanguard, she would extend about 40 meters out each end, and I'm just not sure that would be good for the hull.

If it weren't for the length and weight issues I mention, the Vanguard is no different from any other floating drydock. 1 1 Link to comment Share on other sites More sharing options...

So I suppose that they only lift ships in areas of calm water. I'm thinking that if the lifted ship starts to tip over in rolling seas, that could be a problem. 1 Link to comment Share on other sites More sharing options...

The main deck of some of those oil rigs are 360' above the keel, much taller than a cruise ship. And don't get me started on the container cranes, though those are typically welded down. 2 Link to comment Share on other sites More sharing options...

Capt_BJ Posted July 5, 2019 #2025 Share Posted July 5, 2019 in computer programming there is something called recursion, where a subprogram calls itself in a sort of nesting operation. here VANGARD a sort of self propelled floating dry dock is used to move a 'regular' floating drydock . . . .... a floating dock weighing 11,000 tons was loaded onto the deck of the semi-submersible heavy lift ship Dockwise Vanguard for transport to Klaipeda, Lithuania. Dockwise Vanguard is the world’s most capable heavy-lift vessel with a deadweight of 117,000 tonnes. It is built with an open deck that allows it transport all sorts of large structures such as floating offshore oil and gas platforms. ****************** for the question about the effect of the seas on the dry dock work proress ... the press release about the Carnival dry docking says the VISTA will be 'loaded' off shore, and then the VANGUARD will 'move into protected waters' IOW into the ship yard where the necessary shore facilities are located: machine shops etc. IF there were sufficient DEPTH of water at open space in the shipyard, it could all be done 'inside' After all the existing (broken) floating dock is 'sunk' in exactly the same way. But VANGUARD may have a yet deeper draft to support its sailing capability. 1 Link to comment Share on other sites More sharing options...
