n: an electric generator that produces alternating current.

n: (1) in designing or ordering hoisting (lifting) equipment, the maximum weight that the equipment will be able to safely lift. (2) on diesel electric rigs, the maximum amount of electric power that the generators will have to produce to adequately power the rig.

n: a part made of coils of wire placed around a metal core, in which electric current is induced in a generator, or in which input current interacts with a magnetic field to produce torque in a motor.

n: a carbon block used to make an electrical connection between the rotor of a generator or motor and a circuit.

n: a series of bars connected to the armature coils of an electric motor or generator. As the commutator rotates in contact with fixed brushes, the direction of flow of current to or from the armature is in one direction only.

n: in a pipe prover, an electrical switch activated by the displacement sphere as it moves through the U-portion of the prover. Activating the switch sends an electric current through a cable to a pulse generator.

n: the power supplied to a drilling rig by diesel engines driving electric generators;used widely. dieselelectric rig n: see electric rig. diesel engine n: a high-compression, internal-combustion engine used extensively for powering drilling rigs. In a diesel engine, air is drawn into the cylinders and compressed to very high pressures;ignition occurs as fuel is injected into the compressed and heated air. Combustion takes place within the cylinder above the piston, and expansion of the combustion products imparts power to the piston.

n: An equipment generally for marine drilling which works like this:firstly the diesel drives the generator and then the electric motor drives the rigs.
.

n: the join with a symmetric cataclinal egress bit on both sides respectively, connected to the bit and

n: a machine by which mechanical energy is changed into electrical energy, such as an electric generator on a drilling rig in which a diesel engine (mechanical power) turns a generator to make electricity (electrical energy).
