In the ODELIA study for the European Commission an assessment of the outdoor equipment noise directive 2000/14/EC and its amendment 2005/88/EC has been performed. The directive requires noise marking for 57 types of equipment used outdoors, and sets noise limits for 22 of these. Since the limits have remained unchanged for many years, there is now a compelling need to revise the existing limit values, potentially add new ones and introduce new equipment types where justified. Also the test codes for the many different machines types have been reviewed. Proposals have been made taking available documents and data into account from 2007 until the present. Criteria applied in the assessment included member state requests and information, environmental impact, stakeholder information from industry, notified bodies, authorities and NGOs, technical progress including databases of declared values, economic impact, and quality of the test codes. Tighter limits were proposed for 9 equipment types and new limits were proposed for 28 types currently without limits. 13 new equipment types were proposed to be included in the directive. In this paper the findings, justifications and recommendations of the study are summarised. © 2016, German Acoustical Society (DEGA). All rights reserved.

Hybrid power plants represent an important intermediate step on the way to an energy supply structure based substantially on renewable energies. Natural gas is the preferred fossil fuel for hybridization of solar thermal power plants, due to its low specific CO2-emission and technical advantages by means of integration into the power plant process. The power plant SHAMS ONE serves as an exemplary object of this study. In order to facilitate peaker gas turbines in an economical way to a combined cycle approach, with the SGT-400 an industrial gas turbine of the 10-20 MWel class have been integrated into the base case power plant. The concept has been set up, to make use of the gas turbine waste heat for power generation and increasing the overall power plant efficiency of the hybrid power plant at the same time. This concept represents an alternative to the widely used concept of combined cycle power plants with solar heat integration. Supplementary, this paper also dedicates the alternative to use gas engines instead of gas turbines. © 2017 Author(s).

Whilst many of Germany's neighbors apply probabilistic safety and risk analyses along with the corresponding valuation criteria, this is not yet the case in Germany. Nevertheless risk analyses are carried out in Germany as well. Some of these applications are described in this article. Furthermore possibilities are pointed out for using probabilistic analyses as a complement of the proved deterministic procedure. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The inspections according to § 14 of the German plant safety ordinance (Betriebssicherheitsverordnung) to be performed by an accredited inspection body (ZÜS) are an important milestone within the commissioning phase of a power plant. In the commissioning phase of unit D of the Lingen CCGT plant, the corresponding actions of the manufacturer with its notified body on the one hand and the plant operator with its ZÜS on the other hand were in interaction. The relevant interfaces and scopes of work have been defined through early coordination.

To assess technical installations proactively and decide whether special inspections are necessary to protect employees and third-parties based on the potential risks they pose, a research project called Criteria to assess the risks posed by technical installations was performed. It looks at the effect that potentially dangerous installations can have beyond the immediate surroundings and to what extent inspections can affect how safe technical installations are based on the quality and frequency of the inspections. The results can help determine which technical installations are so dangerous that they require additional monitoring by third-parties and which safety measures for handling these installations should be regulated by law. © 2011 Wiley-VCH Verlag GmbH & Co.

Both in national and in European regulations and rules defaults are contained of the technology for the installation of fire detection and fire fighting systems in rolling stock. These contain however no requirements regarding the verification for functionality, effectiveness and reliability of these systems. For this reason guidelines have been compiled by the "Arbeitsgemeinschaft Brandmelde- und Brandbekämpfungstechnik in Schienenfahrzeugen (ARGE)", which are presented in this publication. The experience shows that the proof procedures are practicably, at relative expenditure feasible and necessary. The ARGE guidelines achieved a large acceptance and are now an important component for the fire protection-technical evaluation in the permission process of rolling stock.

The increasing use of magnesium castings for automotive components and the number of newly developed alloys raise the question of suitable recycling processes. Remelting offers a high potential of energy saving and thereby improves the live cycle balance of magnesium components. Effective recycling processes are likely to involve the mixing of different alloys but little is known about the interaction of alloying elements. In order to approach this issue, the influence of strontium, silicon and calcium on phase formation and mechanical properties of magnesium alloy AM50 has been investigated. After strontium addition, X-ray diffraction demonstrated the formation of the Al4Sr and the Mg 17Sr 2 phases. However, after simultaneous alloying with strontium, silicon and calcium the ternary Zintl phase Sr 6.33Mg 16.67Si 13 was detected. This phase forms preferably instead of Al 4Sr,Mg 17Sr 2 andMg 2Si. Compared to the two strontium-containing phases, precipitates of the ternary Zintl phase exhibit a rather compact morphology. This results in a higher elongation-at-fracture under tensile stress. © 2012 Springer Science+Business Media, LLC.
