FOR Turbine, pump and compressor repairers and energy asset owners
Define the machine and the service commitment
Rotating equipment service can include pumps, compressors, turbines, motors and gearboxes. Identify the machine type, operating duty, repair scope and the contractor’s role in diagnosis. A company replacing specified bearings has a different responsibility from one redesigning a rotor or recommending changes to operating speed. Both may be described too loosely as mechanical repair.
Distinguish scheduled overhaul, emergency troubleshooting and ongoing condition monitoring. The owner should explain whether the machine is a single point of failure and whether a usable spare is available. Those facts affect the likely interruption after an error, even when the repair contract itself is modest in value.
Track the rotor through handling and testing
Customer components may move from a plant to a workshop, testing facility or specialist subcontractor. Record declared values, packing methods, storage requirements and custody at each stage. A precision rotor can suffer damage during handling or storage before any repair work is performed. Identify who arranges the movement and which party bears the risk of loss.
Review property-of-others, transit and rigging coverage alongside liability. Testing and high-speed balancing should be explicitly disclosed. Ask about restrictions involving prototype work, performance guarantees, customer property or the particular part being worked on. Insurance for owned workshop equipment is not a substitute for protection addressing a customer’s machine under repair.
Consider the first run after reinstallation
An illustrative alignment error leads to bearing damage during startup and then damages adjacent equipment. The claim may combine the cost of correcting the original work, replacement parts, inspection of similar machines and lost production. Separate those demands rather than treating the entire invoice as one insured repair claim. Establish who controlled installation, lubrication and the test run.
Review completed operations, professional liability for technical recommendations, and the owner’s equipment breakdown and interruption arrangements. Ask how faulty-work, wear, maintenance and performance exclusions apply. A manufacturer’s warranty may address a defective part without responding to labor, expedited freight or the owner’s lost output. Contract language should not promise broader reimbursement without deliberate review.
Make the technical evidence available
A submission should explain repair qualifications, machinery values, maximum operating exposures, subcontracted services and past failures. Include representative agreements and identify any commitments to output, efficiency or remaining service life. Describe the process for rejecting unsuitable parts or escalating findings outside the original repair scope.
Retain dimensional records, balance reports, parts traceability, alignment readings, test results and the final acceptance conditions. Record changes made by the owner after return. If a failure occurs, preserve components and operating data where safe and lawful, and notify insurers before destructive examination or settlements. The purpose is to establish a reliable chronology, not to assign blame before the technical investigation is complete.
