­When it's time for these non permanent platforms to maneuver on, the really large rigs enter the image. Criticism ranges from dire environmental warnings to considerations over how oil rigs obstruct the view on a vacation seashore journey. These rigs are designed to final decades, usually far from land and in a few of essentially the most hostile waters on Earth. But whereas mounted platform designs are rigid, compliant towers are designed to sway and transfer with the stresses of wind and sea - even hurricanes.
