How was this Naval ship raised?

I was just doing my rounds on internet news and I came across this picture of a recently sunken South Korean naval ship being raised.

Does anyone know what type of vessel is used for doing something like this?

Thanks.

I think it's called a recovery/salvage barge ... its basically a giant floating crane. I have no idea how it is ballasted in order to avoid tipping over, but the whole thing is rather impressive. You can see full shots of it in this video:

I think also in order to raise it so the crane can lift it, they use giant buoys if you like to raise it to a sufficient depth.

Thanks Spectra!
That's an awesome vid. Very impressive floating crane.

Yeah, I've heard about some serious underwater inflatable balloons to assist recovery efforts. Not sure if used here(I've heard that sometimes divers dig a channel underneath a sunken vessel to wrap chains and cables for eventual lift).
And the crane vid by Spectra rocks!
