Jack up drilling rig design

Jackup rigs are so named because they are self-elevating with three, four, six and even eight movable legs that can be extended (“jacked”) above or below the hull. Jackups are towed or moved under self propulsion to the site with the hull lowered to the water level, and the legs extended above the hull. The hull is actually a water-tight barge that floats on the water's surface. When the rig reaches the work site, the crew jacks the legs downward through the water and int. [pdf]

How do rotary screw compressors work?

An oil-flooded system, the more common type of rotary screw compressor, fills the space between the helical rotors with an oil-based lubricant, which transfers mechanical energy and creates an air-tight hydraulic seal between the two rotors. The atmospheric air enters the system, and the interlaced screws push it through the compressor.
