rotorsøk

Rotorsøk is a term used in Norwegian-language discussions of mechanical engineering and maintenance to describe the process of locating, inspecting, and diagnosing rotors—the rotating components within machinery such as steam and gas turbines, electric motors, gearboxes, and turbochargers. The word combines rotor with sok (search), reflecting its focus on locating and assessing rotors within complex assemblies.

In practice, rotorsøk encompasses planning, access and safety considerations, and the possible removal or partial disassembly of components to enable inspection. A typical rotorsøk combines on-site measurements with nondestructive testing to assess rotor condition. Techniques commonly involved include vibration analysis to detect imbalances or bearing faults, infrared thermography to identify hotspots, ultrasonic testing and eddy current methods for material integrity, and imaging approaches such as borescope inspections for internal visibility. Data gathered during rotorsøk inform decisions about repair, balancing, rework, or replacement.

Rotorsøk is relevant in power generation, aviation, and industrial manufacturing where rotor integrity is critical for performance and safety. It may be performed as routine maintenance, as part of fault investigation after abnormal operation, or within planned overhauls. The overarching aim is to minimize downtime, extend component life, and prevent catastrophic failure.

Safety considerations and adherence to manufacturer procedures are essential in rotorsøk, given the hazards associated with rotating equipment and during inspection and service. The term is most common in Norwegian-speaking maintenance contexts and is used alongside related concepts such as rotor balancing, non-destructive testing, and rotor replacement.
