            ENVIRONMENTAL COMPATIBILITY TESTS - In line with natural laws
            Given our long-standing and extensive experience in the assessment of installations and in licensing management useful synergy effects are available during the conduct of the environmental impact study (EIS) or the environmental impact assessment (EIA). We offer all the necessary services on a one-stop basis even for complex projects.

            NOISE PROTECTION - Noise estimates
            On the basis of our many years of experience and measurement equipment, we can help you satisfy the legal requirements and implement your special needs. The respective measures are optimised and assessed while taking economic factors into consideration. 

            SAFETY AND INCIDENT CONCEPTS - Well prepared with sound safety
            In order to allow system operators to effectively minimise their technical risks and to ensure that they are ideally equipped for emergencies, we develop safety concepts for the sites, equipment, framework conditions of the authorisation law, technical regulations, and disaster prevention.

            ODOUR ESTIMATES - The right insight

            For a forecast, odour emissions are projected from odour-relevant system data or agricultural companies (operating times, source levels, number of animals, quantity of exhaust air, etc.) published values and odour-specific data from a variety of measurements of odour emissions taken by our experts. Together with site-specific meteorological data, we conduct a propagation calculation to calculate the odour emissions in the system's environment. These odour emissions tell us how often a system is smelled in neighbouring residential homes. This frequency forms the basis of the assessment as to whether the odours could present a significant nuisance level.

                                • Services for Profitable Wind Power Generation

                                • In wind energy TÜV NORD is serving almost all international manufacturers of wind turbines as one of the leading accredited certification bodies’ world wide. Certifications are carried out according to all international certification guidelines like IEC, EN, GL, Danish approval scheme, DIBt and TAPS. During the certification process TÜV NORD assesses the design of the whole wind turbine including the load assumptions, the safety concept and all components
                                  which gives certainty to the design departments of wind turbines manufacturers. Furthermore TÜV NORD undertakes the required manufacturing evaluation including the quality management system (ISO) – which is necessary for a type certification – as well as different measurements within the type testing. The certification can also be done for separate components like gear boxes, rotor blades, generators and more and therefore helps the manufacturers of these to get access to the wind market. The necessary gear box prototype test can be carried out on our own gear box test stand being operated by our TÜV NORD group sister company DMT.

                                  Wind farm planners, operators or financers make use of the broad experience of TÜV NORD and enjoy the whole spectrum of project related assessment services from one hand:

                                    • Geotechnical Investigation

                                    • A safe and economic foundation design is the basis for all construction projects, not only for wind turbine. The reliability of all further structural components and service installations depend on a successful foundation design. During the last
                                      20 years rotor diameters of wind turbines have increased from 20 m to 120 m, hub heights from 30 m to 130 m and the electrical power production from 75 kW to 5.000 kW. Modern wind turbines with their large hub heights and large rotor diameters produce extremely high bearing loads and have stringent requirements which must be fulfilled by the subsoil. This must be carefully checked by geotechnical experts; otherwise the consequences might be damage to the foundation base or the loss of the wind turbine itself.

                                      TÜV NORD Group has a lot of experience and references in the field of site investigations and foundation design consultancy for wind farm projects.

                                • Winning over customers

                                  Manufacturers of electrical products for industry who want to win over customers have to focus increasingly on energy efficiency. A particularly important aspect is the electrical efficiency factor, which relates to energy consumption during operation. With “Efficiency tested” certification, TÜV NORD CERT offers manufacturers of electrical machinery, uninterruptible power supply (UPS) equipment and other industrial items the opportunity to demonstrate the good ecological design of their products.

                                  More environmental protection – lower costs

                                  All equipment that is driven electrically or converts electrical energy is eligible for the certification process. Measurements are based on Directive 2009/125/EC regarding ecodesign of energy-related products and further standards such as the new IEC 60034-30 for electric motors. Independent testing by TÜV NORD CERT and the associated test mark offer prospective purchasers a reliable means of comparison and show at first glance that energy-saving aspects were considered in the design of the equipment. This not only makes a contribution to environmental and climate protection, but also helps to reduce operating costs.
