  • Safe power from the sea: TÜV SÜD certifies innovative offshore wind-turbine generators for ESTEYCO

    Offshore wind turbine generators (WTGs) provide an important source of sustainable energy. When the Spanish engineering and consulting company ESTEYCO came up with a breakthrough method to make offshore WTGs far more cost-effective, it was TÜV SÜD’s job to develop a certification procedure and give the thumbs-up for structural safety. 

    The job proved challenging: The special conditions for the installation of sea turbines require innovative technologies. The ELISA/ELICAN pilot project, led by ESTEYCO, combines a telescopic tower and a gravity-based foundation that acts as a floater during transport. The entire structure can be assembled from pre-cast parts on a dry dock. For transport and installation, no costly special installation vessels or cranes are needed. During sea transport, the foundation acts as a floating barge and the telescopic tower is retracted to ensure stability while floating. For installation, the foundation of the support structure is lowered to the seabed and the telescopic tower extended. 

    That is where TÜV SÜD came into the game. TÜV SÜD experts of Industrial Service’s wind energy departments from Hamburg and Munich developed a certification procedure that ensures the safe and reliable use of this innovative support structure, both during installation and during operation. In a close collaboration between naval architects and structural engineers, TÜV SÜD performed independent calculations with hydrodynamical and structural models to back up ESTEYCO’s design. 

    The team could draw on their extensive experience in all types of design evaluations, inspections and certifications that are required within the scope of international on- and offshore projects. TÜV SÜD is accredited by the German Federal Maritime and Hydrographic Agency (Bundesamt für Seeschifffahrt und Hydrographie, BSH) for the certification of offshore wind farms and as a certification body for offshore and onshore wind turbines and their components. 

    With the handing over of the TÜV SÜD certification, the pilot project was good to go, and could begin providing environmentally friendly energy for 3000-odd households.



  • Siemens Energy receives first “H2-Ready” concept certification from TÜV SÜD

    Hydrogen fuels is expected to soon start disrupting many carbon-based energy systems, particularly at natural gas-fired combined cycle power plants (CCPP), including ones already planned or being built. Utilities that plan to purchase this type of power plant will expect a statement on the plant's ability to use hydrogen as a fuel. Until now, there hasn’t been a clear definition of what this term means.

    Therefore, TÜV SÜD has developed a guideline describing the requirements resulting from a switch from natural gas to hydrogen as fuel supply for CCPPs. The guideline covers all major systems and components of these type of plants. It describes how plants can be converted over time to co-fire hydrogen or even burn pure hydrogen.

    Siemens Energy has become the first company worldwide to receive a “H2-Ready” certification from TÜV SÜD for their H2-Readiness concept of new-built combined cycle power plants.  The independent third-party certification is now being offered to original equipment manufacturers (OEM) and engineering, procurement, and construction (EPC) companies.

    As climate goals must become more drastic, TÜV SÜD has ensured this certification can be applied to many solutions, enabling other kinds of power plants outside of just CCPPs to make the switch to hydrogen.

  • TÜV SÜD Korea assessing safety of new hydrogen trams in massive, collaborative infrastructure project

    A new project from TÜV SÜD Korea is seeking to build hydrogen fueling stations for hydrogen trams and start mass production for the vehicles. This comes as a part of the hydrogen-electric tram demonstration project from the Ministry of Trade, Industry and Energy (MOTIE) of South Korea, who want to expand their environmentally friendly hydrogen mobility infrastructure.

    MOTIE will begin discussion of the hydrogen-powered public transport with local governments before branching out in overseas regions that have demand from trams such as Europe and Southeast Asia.

    The main goal of this project is to establish the core technologies that will make commercialization of the hydrogen tram possible, and TÜV SÜD is partnering with specialist companies. 

    As the expert provider of TIC services, TÜV SÜD Korea will closely verify whether the hydrogen-electric trams meet domestic and European railroad safety standards. 

    The project partners will work on developing hydrogen fuel systems for use on trams, rather than hydrogen cars, including developing fuel cells and flexible, high-pressure tubes to connect hydrogen storage tanks.


  • Green energy for public electricity: TÜV SÜD experts take over project management and engineering for French large scale offshore wind park

    TÜV SÜD’s experience in the offshore sector had French contractor RTE trust our experts with a multifaceted project. The scope: project management for the marine connections of three offshore wind farms.

    Our contractor RTE is responsible for the management, design and realization of connections – both on land and underwater – for windfarm projects at sea.

    The project, which is running until 2023, comprises three windfarms in different areas of France that will supply the public in their areas with renewable energy. As assistant to the project owner, our experts provide offshore project management, risk management of UneXploded Ordinance (UXO), and the monitoring of work at sea and on land, supporting the execution of the submerged connections to the offshore wind farms.

  • NEOM: Saudi Arabia presents a blueprint for smart urbanity as part of the Vision 2030

    With NEOM Saudi Arabia offers a glimpse into the future of sustainable and smart urban planning – and TÜV SÜD is providing technical advisory for various sectors. Since 2020 TÜV SÜD is a partner in the project and supports NEOM stakeholders in achieving their strategic targets and implementation roadmaps. All projects are closely linked to TÜV SÜDs focus on green energy and sustainability services and demand cross-divisional expertise.
