Axial gas turbine technology is the dominant and appropriate configuration for large gas turbines. Major power plants and industrial plants deploy axial gas turbines to provide power and heat for district heating, process, facilities and electricity to the grid. Less discussed, though, are the lower power ranges where both axial and radial gas turbines are available. It is worthwhile to compare axial and radial turbines where the technologies overlap.
Suppliers often differ on the best way to control turbomachinery. Some advocate plant-wide controls operated by Programmable Logic Controllers (PLC) and Distributed Control Systems (DCS), while others opt for proprietary black box or software-based solutions.
Mitsubishi Heavy Industries, Ltd. (MHI) has concluded an agreement with United Technologies Corporation (UTC) of the U.S., under which MHI will acquire Pratt & Whitney Power Systems (PWPS), the small and medium-size gas turbine business unit of Pratt & Whitney (P&W), an aero-engine manufacturer.
The Cidade de Angra dos Reis MV22, a production, storage and offloading (FPSO) vessel owned by Petrobras, is operating in over 2,000 meters of water above the Tupi Field in the Pacific Ocean. It has to process a mixture of natural gas and CO2 in operating pressures that exceed 500 bar.
Steam and gas turbines were first developed for power generation – a pioneer industry in many aspects – and then adapted for mechanical drive applications such as compressor or pump drive services. As a result, many well-known gas turbine mechanical drive models have been adapted from power generation.
Algeria has set aside $1.06 billion towards setting up a 1,200 MW combined cycle power plant in the northeastern town of Ain Amat. The contract has been awarded to a South Korean consortium, and the deal is expected to ease the North African country's acute power shortage, according to consortium member Daewoo International.
Plant machinery safety and reliability begins during the project phase. Input from lessons learned and incorporation of the resulting best practices into the earliest phase of the project will ensure a plant that it enjoys optimum safety and reliability for its usable life.

A strong fourth quarter in fiscal 2012 has enabled the German manufacturer Siemens to fulfill expectations and achieve one of the best years ever, according to Peter Löscher, President and CEO of Siemens AG. The company has achieved a seven percent gain in revenue and a strong profit in the fourth quarter.
The gas turbine marketplace will undergo significant changes in the decade between 2012 and 2021, according to Forecast International. The biggest gains will be in the maintenance, repair and overhaul (MRO) space where the current global total of $7.8 billion is expected to double within 10 years.
New regulations from the U.S. Environmental Protection Agency (EPA) and the low price of natural gas were the two most powerful forces affecting current and planned U.S. coal-fired generation in 2012 and 2013. At this point, we see both forces continuing to shape coal generation over the next few years.
Dresser-Rand has entered into a service agreement with NuScale Power, LLC.
The agreement allows for an integrated delivery model that includes design, engineering, U.S.-based manufacturing, and operational support from Dresser-Rand’s worldwide service center network. The goal is to ensure optimum performance of the turbine generators that will be paired with NuScale Power’s small modulator reactors (SMR).
Below is a case study from the paper, \"Babbitted bearing health assessment,\" by John Whalen of John Crane, Thomas Hess of Dupont Engineering, Jim Allen of Nova Chemicals, and Jack Craighton of Dupont Engineering at the 41st Turbomachinery Symposium in Houston, Texas.
The case study involves a large centrifugal compressor in charge gas service in an ethylene plant. The unit was running fine when a power outage shut the plant down. The train came down fine but when brought back up it was noted that one bearing exhibited high levels of vibration.
Siemens plans to divest its solar business activities and is currently holding talks with potential buyers on this subject. Siemens intends to focus its renewable energy activities on wind and hydro power. As part of this reorganization, the Energy Sector will be slimmed down and the Solar & Hydro Division will be discontinued. Strengthening the company’s focus on core activities is one of the five main points of the new company program 2014, the broad outline of which was recently announced to the public.
At its management conference in Berlin, Siemens AG presented the basic structure of its new company-wide program to some 600 top executives. The emphasis on cost cutting and organizational restructuring has led to fears over job losses across divisions. But Siemens executives promise that the new program's goal is not to cut jobs.
GE Oil & Gas will supply gas compression trains for Cheniere Energy’s Sabine Pass liquefaction expansion project in Cameron Parish, La., about 170 miles west of Baton Rouge. Adding liquefaction capabilities will transform the existing Sabine Pass LNG terminal into the first LNG terminal capable of importing and exporting liquefied natural gas (LNG) in the U.S.
The 2012 Turbo Symposium took place in Houston in September with attendance up slightly on last year, according to Dr. Dara Childs, Director of Texas A& M’s Turbomachinery Laboratory which organizes the event. Consisting of technical sessions, a large exhibit hall and short courses, it attracts the main players in the oil & gas field each year.
