Case Study - High Speed Gearbox Overhaul
A UK facility receives and processes North Sea crude oil for use across numerous industries. Product delivery & plant availability is critical in this environment.
The customer was experiencing gear unit problems following overhaul by a third party. We were asked to investigate & quickly found gear tooth failure. We followed up with a full inspection report & a proposal to overhaul and test & certify the units, including replacing the gearing and bearings as required.
Cyrus-Bradford engineers inspected all the components recording details and specifications. The main gear components – damaged in service were inspected and gear geometry calculated. Engineering drawings prepared & approved prior to manufacture. Replacement parts were supplied in correct materials and heat treatment to suit the application.
The unit was re-assembled, test run & certified at Cyrus-Bradford workshops with the client in attendance. Condition monitoring values were said to be to finer limits those previously achieved by OEM.
The package was successfully installed & commissioned and went onto exceed anticipated running hours. The customer now sends the remainder of these units to Cyrus-Braford for scheduled overhaul on an ongoing basis.
