People been talking about wonderful things humans invented like car, aeroplane and others, but few talk about wonders that's on the sea.

When you witness semi submersible crane vessels like Saipem 7000 brings in an offshore platform to install in the middle of the sea, you'll be amazed.
This is a platform that consist of over 4 decks: Sub cellar, cellar, main and upper or top decks. It'll rig it and perfectly position it in place even with the roughness and depth of the sea.
This is a platform with large and heavy pipings, vessels and machines like turbines, multi stage compressors and generators.

Mehhhh, who brought up the idea of designing these sea vessels to do all these was really a genius.
