Safer, Better, Faster
With the introduction of the patented Genesis BQ series oil rig, B Robotics W Srl, an Italian oil rig manufacturer, sets a new standard for rig safety, performance, and speed.1 The Genesis Rig represents the most important advancement in new technology since 1923, when rigs transitioned from percussion to rotary systems.2
For more than 60 years, the diesel electric rig has been the stable of the industry. It utilizes a drawworks to spool a cable in and out to hoist and lower drill strings, etc.3
The Genesis Rig’s key innovation is the replacement of the drawworks with long-stroke hydraulic cylinders (installed on each side of the mast frame), which are safer, more powerful, dependable, and precise.4 The cylinders are activated by rugged gear pumps controlled by VFD modules, which alter the volume of oil delivery and traveling speed of the top drive.
The hydraulic cylinders’ fixed stroke makes possible the rig’s second major advancement – the highly reliable automation of repetitive actions, including tubular handling, string pull out and running, casing running, drilling, etc.
As a result of the hydraulic cylinders and automation, the Genesis Rig can trip in and out at a speed of more than 1.5 m/sec, compared to .5 -.6 m/sec for a conventional rig, as well as handle three range 2 drill pipes.
The Rig’s automation also is central to its ability to operate in severe hot and cold temperatures. Automation eliminates the need for workers on the drilling platform and monkey board. A single individual in the climate-controlled driller’s cabin can trip, change bits, change stabilizers, etc. Chillers prevent electric motors on the Genesis Rig from losing power from overheating in warm climates. And heated water is pumped through the system to allow the rig to operate in extreme cold temperatures.
Knowing that rig breakdowns can be costly, engineers at B Robotics W carefully selected components for the Genesis Rig based on dependability and field tests. The Rig’s systems are designed for simplicity in function, ease in understanding, and low maintenance. Redundancies are built into key components to eliminate single-point failures.
