7 Stunning Oil Platforms

An oil platform is a large structure used to house machinery & men who drill or produce oil & natural gas from the ocean bed. These platforms may be attached to the ocean floor that consists of an artificial island or may be floating, depending upon the circumstances.

The T. A platform is a huge platform for production of gas, it is the highest construction that has ever been moved to another position, and is among the largest and most complex engineering projects in history. Built by Norwegian Contractors for NorskeShell, the platform was a televised sensation when it was towed into the North Sea in 1996, where it is managed & run by StatoilHydro.

Natural gas is separated on-board. Most is utilized in the gas lift system, some is used for fuel and a small quantity is flared in conjunction with process control.

  1. I have to admire the efforts of the workers on oil platforms. They have to work in the middle of the ocean, far from their families, and with little protection from the weather. Yet, without them, the world might have even more serious oil problems.
