Case Study

Drawworks for Offshore Drilling Rigs


A world-class manufacturer of transmissions for hoist and drawworks used in off-shore oil drilling and production rigs.


Multiple incumbent suppliers were not able to provide compatible sintered and paper friction gears and corresponding steel plates in a timely fashion. The customer required tier-one parts which would meet or exceed the existing suppliers’ quality. ProTec was asked to provide a reliable, cost-effective single source for multiple wet friction parts and components that were previously sourced from multiple vendors.


Working with customer engineers and production managers, ProTec delivered samples which excelled in rigorous 3 rd party laboratory testing and analysis in the first round. Production parts required sophisticated heat treatment, specialized hardening, and precise finishing.

All parts were delivered and accepted on a tight schedule. ProTec even made special international delivery arrangements which save the customer thousands of dollars in cross-border shipping fees.
