Help in searching a manufacturer

[eng.naval]

Can anyone tell me how can I find a building berth builder(slipways,keel blocks,...etc) i.e complete equipment of a building berth.
Any keyword so I can search it will be very helpful.

Thanks

dry docks

concrete pontoons? or if building on land, just a leveled reinforced concrete slab and runway into the water (hobby build?), for larger commercial build go to a yard that can handle the size you desire to build?

Thanks Mark, but it's not dry docks. I know dry docks.
Masalai, we are actually a shipyard in Egypt, and we are looking for a company that builds a building berth,or should I say the equipment, and particulary i'm looking for a chinese company.

I think I found what I'm looking for.It's called mechanical slipway.Any help in finding a company that builds these slipways will be great.
Thanks
