TWO NEW GAS TURBINES FOR OIL & GAS

I believe that GE Oil & Gas’ additive manufacturing facility in Talamona, Northern Italy, uses laser technology. Haven't seen anything to suggest EBM units but these turbines have low pressure turbines very similar to the kind used in jet engines. The increased production rate that EBM delivers on complex parts is a positive compared to the laser technology.

LM9000 continues the tradition by drawing on the unparalleled global flight experience of GE Aviation's GE90-115B, Boeing's 777 engine since 2004. GE has announced that they're incorporating EBM components in current and future GE90's. There's been no mention if the additive components are also being utilized in the LM9000 but there's no reason to believe that those technology advancements wouldn't be included - especially considering the continuing mantra of "The GE Store". And the fact that Mohammad Ehteshami, GE's Vice President - Additive Integration, spent six years developing the GE90 jet engine.

TWO NEW GAS TURBINES FOR OIL & GAS - March 18, 2017

At the Annual Meeting, the company unveiled the NovaLT12 as the third product of this new line. The standard model delivers 12.6 MW. But there will be future design options for power requirements from 10.5 MW to 13.9 MW.

This turbine has been designed to have higher efficiency and lower total cost of ownership than market peers, said Christie, and provides over 80% efficiency in cogeneration applications. But it will have a focus on oil and gas midstream operations — both mechanical drive and power generation.

Christie added that it would do well in various upstream and downstream applications. This includes its use as a generator drive in industrial power generation, combined heat & power (CHP), offshore power generation and mechanical drive (pipeline). Industrial applications are likely to include pulp & paper, cement, chemical, petrochemical, steel, biogas and district heating.

Due to standardization of design and modularization features, the company is advertising 36 weeks from order placement to delivery and an 8-week installation. The turbine’s fuel burners are manufactured using 3D printing technology at GE Oil & Gas’ additive manufacturing facility in Talamona, Northern Italy, which began production in 2016.

“Additive manufacturing (AM), together with automated manufacturing techniques, allows us to develop parts and products more efficiently, with better performances and more cost-effectively; this accelerates the speed at which we can bring product to market,” said Christie. “Compared to traditional production techniques, AM offers the possibility to realize any form in a single piece without having to join pieces.”

The improvements are significant from the point of view of the characteristics of the base materials: Production by successive layers offers detailed control of the structure as well as the homogeneity of the part. Production times are also reduced. The finished product can be obtained in weeks instead of months. In addition, additive manufacturing enables the company to optimize the design of gas turbine combustion components to suit tailored requirements, such as low emissions for NOx and CO2.

At gereports.com, Mohammad Ehteshami's work on the GE90 jet engine is mentioned - An Epiphany Of Disruption: GE Additive Chief Explains How 3D Printing Will Upend Manufacturing - Mar 6, 2017

At GE, he spent six grueling years developing the GE90 jet engine, the world’s largest and most powerful jet engine in service. He had one last idea for getting the nozzle made.

For many years, GE engineers had been using the bespoke machines in Morris’ workshop to print prototypes of new engine parts and rapidly iterate new designs. But Ehteshami and others involved in the project now wanted to know whether Morris would be able to use 3D printing for mass production of a complex part, something nobody had tried before.

They swore Morris to secrecy and sent him the computer file with the drawing of the intricate nozzle tip. He printed it from a nickel alloy and invited the team over a few days later. “I remember that day like today,” Ehteshami says. “I was excited but also disturbed. I knew that we found a solution, but I also saw that this technology could eliminate what we’ve done for years and years and put a lot of pressure on our financial model.”

The nozzle met the team’s wildest expectations. Morris’ machine not only combined all 20 parts into a single unit, but it also weighed 25 percent less than an ordinary nozzle and was more than five times as durable. “The technology was incredible,” Ehteshami says. “In the design of jet engines, complexity used to be expensive. But additive allows you to get sophisticated and reduces costs at the same time. This is an engineer’s dream. I never imagined that this would be possible.”

The beam enables the machines to print faster and fuse layers as thick at 100 microns, twice the width of what a laser can print. It also can grow parts from wonder materials like titanium aluminate (TiAl), which is 50 percent lighter than steel but very hard to shape. Image credit: Mark Trent for GE Reports
