Oasis incident at Freeport Shipyard

Recommended Posts

VG is in Freeport ... Marine Traffic 6pm

and I'll guess that right now they are working on how to deal with shore support issues as the ship parks here, with VISTA .... in the past this area has only been used for "dockside work"

 

VISTA is still on a trip ..... no where near yet . . .

There is crane support in that area, that's about all they will need.

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.

Yep. While the drydock areas of Grand Bahamas Shipyard may be dredged to around 17-18 meters to allow the docks to sink enough for ships with 8-10 meter drafts to enter, the channel and everything in the port is only 16 meters.  Vista has a draft of 8.2 meters, there will be 1-1.5 meter tall keel blocks, and the Vanguard has a draft of 11 meters (a lot more than a non-propelled dock) in sailing mode, so she would need 21 meters of depth just to load the Vista, and you would want 3-5 meters under the keel of the Vanguard when she is submerged, so figure they need about 24 meters of water to load the ship, and then they will pump up to 11 meters, and go into the shipyard.

RCL should sail there for those of that just want to watch an engineering marvel. I would love to just watch the logistics of loading the vista and getting into port. Be a good alternate stop to all the lost Cuba stops.

...or some of us can just wait until it comes out on Blu Ray... 😁

Amazing video.  Thanks for sharing.

 

This type of dry dock must be more expensive than a "normal" dry dock.

Since Vanguard is really just a "self-propelled" floating drydock, the "days" in the dock should not be much different, but there will be a cost differential.  A shipyard charges a per day charge (maybe $20k for a dock this size), and a flat fee for "docking/undocking", which includes the cost/time/labor to set the keel blocks for the ship, pumping and refilling time, tugs, pilots, line handlers, divers, etc.  Dockwise most likely has a flat rate charter with Carnival, where the cost is calculated starting from the time the Vanguard left it's last job, wherever that was in the world, the cost of repositioning the ship to the Bahamas, the time spent setting blocks and waiting for Vista, the cost of tugs, pilots, etc to "load/unload" the Vista, and most likely the time and cost to "redeliver" the Vanguard to a mutually agreed point in the world.

I would think that the cost likely is a function of the lost revenue had Vanguard not been redeployed from another job. I doubt it sits idle for very long if at all.

Whose lost revenue?  Dockwise sets a day rate for charter that covers their operating expenses.  As I said, there will be a "mobilization" charge, and a "redelivery" charge to cover cost between the last job and the redelivery point.

Yes. wonder if they have plans for one that is large enough to handle Oasis class and larger.

Well, there were floating drydocks that were towed all around the Pacific Ocean during WW2, and this is just a "self-propelled" model.

Probably not.  The market for lifting cruise ships would be very small, especially ones bigger than Vanguard could handle, they make their bread and butter on offshore oil, and Vanguard can lift the biggest of these projects, though I do see that Dockwise has "plans" to build a larger version sometime down the road.

 

Now, something that I find incredible is this twin-hulled offshore construction and pipe laying ship:

365K tons empty, wow.

And with a million tons full load displacement, you could stack 6 Oasis class ships on her and not sink her.

What's the displacement of the largest supertankers?

The largest tanker ever, Seawise Giant, had a full load displacement of 656k, but she has gone to scrap.  The largest tanker currently operating are the "TI" class, like the TI Asia, at 509k tons.  The largest bulkers come in around the same size.

Something like 5 US Navy aircraft carriers.
