Turbomachinery International: July/August 2023

Published on: 

In the summer July/Aug 2023 issue of Turbomachinery International, we examine gas turbine and compressor repair and maintenance trends, provide an outlook on the future of hydrogen as a gas turbine fuel, deliver a report on gas turbine sales in 2022, and more.

The gas turbine maintenance, repair, and overhaul market continues to show signs of growth due to an aging fleet of gas turbines and government interventions designed to reduce carbon emissions. The cover story of the July/Aug 2023 issue of Turbomachinery International explores the emerging market dynamics that continue to play a role in the turbomachinery repair and maintenance landscape. Inventive and modern methodologies that include virtual tools, predictive and preventative maintenance, 3D printing, and precision measurement technologies are taking repair and maintenance to the next level. And, as a complement to our cover story, Turbo’s assistant editor took a trip to Bethlehem, PA, to visit Rotating Machinery Services’ facility to get an inside look at their in-shop repair and maintenance operations.

Our summer issue also explores the four phases of commissioning turbomachinery with Amin Almasi in his Turbo Tips column. This issue also presents a case study by Saudi Aramco that details the investigation of a spare magnetic drive pump that was producing abnormal sounds in a sulfur-treating unit.


Further, former editor Drew Robb delivers a report on gas turbine sales in 2022, which rebounded to 50 MW worldwide, up 47%, although 2023 sales are expected to be lower.

We also have a special feature by Jason Neville of ENTRUST US on the future of hydrogen as a gas turbine fuel. He dives into the ins and outs of running traditional gas turbines with hydrogen, including a comparison to natural gas and how it will impact the various gas turbine specifications and components.

The Myth Busters tackle dual drives—a combination of an electric motor and a gas turbine to power a centrifugal compressor—and how they play on the individual strengths of each driver in a single package.
