Mechanical, pressure and integrity
Rotating equipment engineering
Selection, assessment and reliability of pumps, compressors, turbines and drives.
Describe your projectWhat it covers
Rotating equipment engineering covers the specification, selection, assessment and reliability of pumps, compressors, fans, blowers, turbines, gearboxes and their drives. The work spans hydraulic and thermodynamic duty, rotordynamics and vibration, sealing and bearing systems, lateral and torsional analysis, and root-cause analysis of failures. The engineer can write the datasheet and specification, review a vendor proposal against the API standards, or diagnose a recurring reliability problem.
When you need it
You need a rotating equipment engineer when you are specifying or buying critical machines, when a pump or compressor keeps failing, when you see high vibration or short bearing and seal life, or when you want a reliability review before a major shutdown. They are the bridge between the process duty and the machine that delivers it.
Standards, codes and tools
Commonly used tools: Bently Nevada, Ansys, rotordynamics software.
What to look for
Look for an engineer who works to the API machine standards and who can read a vibration spectrum, not only a datasheet. Ask whether they have handled your machine type and service, because a high-speed centrifugal compressor and a slurry pump need different expertise. For a reliability problem, look for someone who chases the root cause through the bearing, seal, alignment and process, not just the symptom.

Common questions
What does a rotating equipment engineer do that a general mechanical engineer does not?
They specialise in machines with moving parts, so rotordynamics, vibration, bearings, seals and the API machine standards. A recurring vibration, bearing or seal problem usually needs that depth rather than general mechanical design.
Can you review a vendor proposal for a new compressor?
Yes. A common engagement is a technical bid review against the relevant API standard and your duty, checking rotordynamics, materials, sealing and the test plan before you commit to a machine.
