The upper deck plan shows the overall location of machinery and equipment on board the rig. The top-most deck is the "heliport." Helicopters are used to quickly transport personnel and equipment as needed. It is located above the living quarters. The upper level of the living quarters are made up the Galley (kitchen), dining area, recreation area, the tool pusher's office suite and the company man's office and quarters. The lower level living quarters contains: crew changing areas, group shower room, crew's lockers, and toilet facilities; personnel staterooms, storage areas; and the rig's "hospital" or first aid station.

This diagram shows the location of other equipment needed for the rig's performance. Shown here are the mud tanks, mud sack storage room, mud pumping units and bulk tanks. The Cellar Deck, marked "moon pool," is where the well is drilled, and is located below the drilling floor.

The diagram shows the derrick in the raised or drilling position and in the lowered or moving position. The derrick is lowered any time the rig is being transported. The barge on which the drilling rig is built houses the motors, generators and pumps, used to operate the rig. Also located in the barge are the compartments called "ballast tanks," used to sink the barge and hold it on location. These tanks are flooded with sea water once the barge in on location. There are rubber tires mounted on steel columns, called bumpers. These protect vessels that tie up to the rig (when the weather permits) to load and offload cargo and personnel. The legs support the rig or platform and connect it to the barge. They can also be used to access the barge from the rig.
