LNG aeroderivatives

The Darwin LNG Facility is the world’s first liquefaction facility to use aeroderivative gas turbines for its refrigeration compressors. The application of aeroderivative engines allows a significantly lower CO2 footprint of 20-30% compared to the use of simple cycle industrial (heavy duty) gas turbines.

Kobelco plant

Kobe Steel, Ltd. has announced that subsidiary Kobelco Compressors America, Inc. (or KCA) is opening a new $20 million factory complex that will double its manufacturing capacity of compressor systems.  KCA has also moved its headquarters to the new facility.


LNG seal

John Crane GmbH has announced today it has been awarded a significant new contract to supply engineered sealing technology solutions to a major Liquefied Natural Gas (LNG) production project in AustraliaJohn Crane will supply 96 of its Type 28 gas seals for first fit applications to Siemens AG, which will provide compressors for the upstream section of the AP-LNG project in Queensland.

The market

A year ago, Axford Turbine Consultants (www.axfordconsulting.com) predicted that GT orders for U.S. job sites would be down 9 percent and worldwide orders would rise by 7 percent.


In waterwashing, the water pressure and temperature are controlled and chemicals added to maintain water quality, which is crucial to the cleaning action. Recent waterwash skids, however, incorporate Moisture Recovery Units (MRU) that generate pure water. The conductivity of water is a good measure of its purity. The less conductive the water is, the more pure. An MRU can provide the required megaohm level needed to assure foreign film deposition extraction during the 10 to 20 minute (turbine size) wash sequence.


Mega utility

Duke Energy Corp. and Progress Energy, Inc. have filed applications seeking regulatory approval of the merger the companies announced Jan. 10. An application to the N.C. Utilities Commission (NCUC) filed today outlines numerous customer benefits that will occur as a result of the merger. They include:


Bog-down control

Gas turbines are commonly used to drive large compressor systems that are used, for example, in the refrigeration cycles of processes for liquefying natural gas. In order to maximize the efficiency of such turbine/compressor systems, the gas turbines are typically operated at or near their maximum rated speed and load. Various changes in the operating parameters of a turbine/compressor system may cause the turbine to slow down.

7FA validation

GE has employed an incremental approach for the 7FA.05 gas turbine, which is the latest evolution of its F class. The gas turbine produces over 180 MW in simple cycle. Only existing proven technologies are used in the machine. These include: 


Aviation heritage compressor design utilized on Heavy Duty Gas Turbines  (GE5, GE10, 5002E, 6C ) 

GE buys converteam

GE Energy has entered into an agreement to acquire approximately 90% of

Converteam, a leading provider of electrification and automation

equipment and systems, for approximately $3.2 billion. 


IGCC sequential combustion

A patent has been awarded to Adnan Eroglu, Jaan Hellat Felix Guethe and Peter Flohr (Assignee: Alstom Technology Ltd.) for a method to operate a gas turbine with sequential combustion to an Integrated Gasification Combined Cycle (IGCC) plant. Alstom gas turbines, such as GT24 and GT 26, feature sequential combustion with reheating by a second combustion chamber. This offers the possibility of operating each of the combustion chambers with different fuels.
