A compressor’s seal system is the culprit of most common unscheduled shutdowns.

Turbocompressors with side streams are operated with tight tolerances on operational parameters compared to conventional compressors.

A steam turbine’s control system should ensure stable operation throughout each phase: start-up, shutdown, and parallel operation.

After a failure or unscheduled shutdown, if the root cause is not found and eliminated, it can happen again.

Gas turbines, including the air compressor and combustion chamber, face challenges such as high temperatures and the need for blade-cooling systems.

Bolt connections can be the weakest link of a turbomachine, so proper care, sizing, tension, and placement are key to avoiding leaks and other operational problems.

Considerations when selecting a lube oil include oxidative and thermal stability, viscosity, interactions with oil additives, and more.

Guidelines and technical notes for dealing with lube oil, control, and hydraulic oil systems in turbomachinery.

Disturbance speed, degradation, the surge curve, and other factors and components affect the efficiency and functionality of a turbocompressor.

The four phases of commissioning are important developmental stages for any turbomachinery package.

Knowing how and when to select an mVSD is important in the turbomachinery industry.

Why simple models estimating impact, dynamic, and blast loads provide insight.

How to operate and troubleshoot hydraulic systems for turbomachinery

VSD double-casing vs. integrally geared

Leakage sources include seals, thin shells, and bolt connections

CHALLENGES AND DIFFICULTIES OF PARALLEL OPERATION

How operation & process can affect turbocompressors

Practical issues for centrifugal fans

Real-world operational turbomachinery problems can be challenging. Fast decision making is often required.

A step-by-step guide on the turbomachinery specification process, including considerations for unusual conditions and indoor vs. outdoor installation.

Surge can be a major challenge for turbocompressors. Operation in the surge area will result in an instability, exposing the machine to destructive stresses and forces, high vibration, and even serious damage.

Many factors once considered negligible in ordinary piping may become significant for piping connected to turbomachinery.

There are many reasons for turbomachinery problems and failures. Resonance, for example, is often overlooked.
