The customer is a joint venture between Petrofac and GS E&C on behalf of Abu Dhabi Gas Industries Ltd. (GASCO), responsible for the fractionation of natural and associated gas from onshore oil operations in the emirate of Abu Dhabi. Siemens will be the main electrical contractor for GASCO’s Ruwais 4th NGL train, located in the city of Ruwais, UAE. The train is scheduled to go into operation in March 2012.
As main electrical contractor (MEC) for the NGL fractionation plant, Siemens will provide power- and distribution transformers, high-, medium- and low-voltage switchgears, and motor control centers. The company’s scope of supply will also encompass a power management system, medium- and low-voltage motors, and various other items of equipment. The order also includes engineering, installation, commissioning and supervision of the complete electrical equipment. Benefits of the ‘one-stop’ MEC approach are the reduction of interfaces, project management simplification, better communication, risk reduction and the leveraging of core competencies. Beyond this, the use of Siemens Oil and Gas standard and modularized solutions is expected to reduce lead, installation and commissioning times resulting in a more robust plant with improved overall operability and better economics.
“This order is a breakthrough for our integrated solution capabilities and a door-opener for further projects as it demonstrates our ability to engineer and deliver the entire power solution scope from a single source,” said Tom Blades, CEO of the Oil and Gas Division of Siemens Energy. “More and more we see customers turning to Siemens early on in projects to find innovative ways to reduce risk and costs while accelerating completion.” Siemens had already been successfully involved in the previous NGL trains at the Ruwais plant in providing smaller packages and components.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
