Maintenance & Repair

The Turbomachinery News Network, for the week of October 20, 2025, covers news from NextDecade, Everllence, Doosan Enerbility, ExxonMobil, and Capstone Green Energy.

The motor pipeline compressor design eliminates the need for dry gas seals and lubrication systems, leading to higher reliability and minimized lifecycle costs.

This win marks the company’s first overseas export deal for gas turbines, with Doosan Turbomachinery Services performing maintenance at its Houston-based location.

The Turbomachinery News Network, for the week of October 13, 2025, covers news from EthosEnergy, Mitsubishi Power, Ebara Elliott Energy, and Shell.

With the energy transition accelerating and much of the existing infrastructure reaching the end of its operational life, modernization has become essential for the gas transmission sector to maintain safety, capacity, and environmental performance. One standout example is the recent Cab Infrastructure Project undertaken by Braden, a global leader in gas turbine auxiliary equipment for Gas Turbine Systems. Tasked with revitalizing a Gas Turbine compressor unit at a critical site in the South of England, Braden delivered a solution that not only extended the unit’s operational life but also prepared it for a cleaner energy future.

Thin-wall casings and shell bodies play a critical role in turbomachinery, but their susceptibility to imperfections and buckling raises leakage and failure risks.

The new infrastructure includes a new power line, main 138-Kv breaker, 100-MVA power transformer, and numerous capacitor banks to allow full-speed, full-load testing.

Using a proprietary mix of sand and other particles, the dust-ingestion testing aims to replicate how parts may withstand flight conditions in harsh operating environments.

The September/October 2025 issue covers steam turbine optimization, a pump-centric conversation with the Hydraulic Institute, hybrid grid technology for stabilization, and much more.

In addition to servicing critical oil and gas safety systems, EthosEnergy’s Approved Repair Facility designation will enable faster turnaround times and localized support.

The refurbishment covers engineering studies, manufacturing, on-site dismantling, installation, and long-term maintenance operations for Unit 1 at Cernavoda Nuclear Power Plant.

By using a fast-starting independent gas power plant, data center operators may come online faster with increased energy security and electricity to the grid.

The Turbomachinery News Network, for the week of September 29, 2025, covers news from Mitsubishi Power, Kawasaki Heavy Industries, Baker Hughes, bp, and Rotating Machinery Services.

The company’s compressor testing suggested that single-piece rotor manufacturing enables higher tip speeds, which maintains an optimal pressure ratio for compressing hydrogen.

The new headquarters will house advanced capabilities such as laser scanning, virtual assembly, metrology, and much more, allowing RMS to serve Gulf Coast customers quickly.

The key liquefaction equipment, including Frame-7 turbines and centrifugal compressors, allows Sempra Infrastructure to expand LNG export capabilities in the United States.

The non-contacting, gas-lubricated seal offers simplicity of maintenance, reduced downtime, and significantly minimized power consumption—up to 90 – 95% less usage.

Mechanically sealed pumps are subject to cavitation damage, thermal shock, and more when operating with ammonia, so operators deploy sealless designs to counter corrosive effects.

The plant will capture, purify, and liquefy up to 30,000 tons of CO2 per year, which is then transported via tanker for use in the food industry.

The European Union’s Clean Aviation Joint Undertaking aims to transform aviation toward decarbonization, sustainability, and new propulsion concepts.

Dr. Eric Petersen, Director of the Texas A&M Turbomachinery Lab, discusses a focus on centrifugal compressors, vibration and reliability, and new short courses at TPS 2025.

Facing rising demand, decarbonization targets, and supply chain volatility, John Crane’s Nico Schmaeling urged turbomachinery professionals at the 2025 Turbomachinery & Pump Symposium to address the energy trilemma—security, affordability, and sustainability—through smarter design, efficiency upgrades, and cross-industry collaboration.

A major ethane transmission company installed the Type 8628VL seals on inconsistent pump equipment, achieving non-contact performance, low leakage, and zero failures.

With the new Flex selective catalytic reduction system, ship operators may reduce their physical footprint by up to 42% and cut NOx by 75% compared to IMO II limits.

The new gas turbines, steam turbines, and auxiliary equipment will increase power generation capacity to meet rising industrial and residential electricity demand.
