Required by Soilmec , one of leading drillrig manufacturers in Italy, project G 500 came from a strict collaboration between Mr. Pietro Ferrara and me.

I learned most of what I know about offshore oil drilling from my friend Pietro, and I was very glad to collaborate to this fine concept design.
This rig featured two movable lifting guides, not rigidly linked each another, and an uncommon reeving, which allowed the drilling head to be lifted and lowered using one only or both the guides, thus achieving freedom of movement, speed regulation and a built-in heave compensation.

Furtherly developed by Studio Tecnico Pietro Ferrara, this interesting rig was inserted also in a concept design performed for SAIPEM , but it hasn't yet been completely realized.

Some experts think this design is the most advanced offshore drillrig available nowadays.

Further development included a 3D modeling to define more details.
