An offshore rental company was using a patented Drill Pipe Circulation Tool. While the tool worked well, the customers wanted a few improvements to it. Within a few months, the DrawWorks Engineering Team was able to design several improvements that include: reduction of the overall length by half, 100% adjustable mounting brackets, newly designed gearbox with impact break out and clutch feature and a remote activated valve that doubled the flow area allowing them to pump more fluid. These features allowed the tool to be used on rigs that were originally not accessible. This improvement was granted a patent.
