A couple of those air bag rollers would make a nice Zodiac or mount a platform on top of them and have an indestructible pontoon boat

I'm assuming divers must retrieve the supports. Very cool looking modern tanker...and Big!

Proves she's boyant . Seen side tipping by trucks but this is impressive.

What a beautiful ship. the runway slip runners ate attached to at least one side (port) for retrieval I guess.

The guy who tripped was on his own no way to stop the ship once it started to move

Alright, it's official. Ship Launches is definitely a thing. A good thing. And that includes boats and submarines too.

I think I'll get aboard after the pod is launched.

Not sure which would be more dangerous staying onboasrd ship until it sinks or having to ride that pod when it was being launched
I'll take my chances with the ship.

I've been trying to get my hands on one of those lifeboats like that. When I find them, they are to far away or to costly.

You will note the cradles are attached to the ship via cables and turnbuckles. These are released once the ship is stable and in a suitable position for crane access. Then divers, (like myself), either bring them to the surface with air bags, or attach the crane directly to the parts for retrieval. Done it numerous times.
Would love some more info on the launch of the "Tasman" as it seems to be a ship destined for Australia

Cheers Phil

Me too, I'd love to see more. The Tasman just possibly, may be destined for the Netherlands to service all those underwater baffles/louvers that control water surges & protecting that underwater country= wouldn't want all those pretty flowers drowned or clogs ruined. They have some very talented Engineers there.

Don't they typically have life boats like that on offshore oil rigs? Those guys are tough, they can handle a ride like that.

And fit a spew bag over the head. Also saves cost of going to the theme park, just in one bounce.

They are tough just like their bullet proof underwear.

Agreed. Good evidence of lax procedures. No spotters, no 2-way radios, no hand signals. One man appears to have jumped in. Hope he wasn't crushed against a pier by the wave, as it didn't seem to have surfed him back out on the pavement.

And I don't think your auto club card covers this size of towing. A Lincoln in the ditch is one thing. 130-odd ton vessels another.

Try as they might there will never be another Lucy and Ethel team.
Some things just worked like Abbot & Costello, Laurel and Hardee The Marx Bros' Lucy & Ethel to name a few. Not always just the comedy acts

Airbag ship launch fail.

I don't think that failure had anything to do with the air bags. There is no way that thing could be stable. Only about 1/5th of it's main mass was below the water and the superstructure was above even that. How could it possibly have stayed upright? One wonders if the engine was even installed yet. There was an obvious, complete lack of ballast. Unless the bottom plate was 12" thick, the center of buoyancy was far, far below the center of mass. They weren't even close.

Physics works.

Agreed that vessel was launched way too green
