HIGHVOLT Prüftechnik Dresden GmbH

With the ongoing boom in Offshore Wind accelerating it is critical for operators and insurers to have confidence in the cable system and it’s accessories. The installation process can be complex with many challenges this increases the risk significantly to the system. Installations are carried by 40+ skilled Fibre Optic, MV / HV technicians. Quality of workmanship is a critical factor to the success of the installation, controlling this offshore is imperative. The final commissioning requires robust test techniques to provide confidence the Assets life expectancy can be met.

Ross Piercey studied Electrical Engineering at Anglia Ruskin University, Cambridge. Responsible for all assets required during the installation & Repair of Oil & Gas Umbilical’s and Renewable Subsea Inter Array Cables in EMEA for JDR Cables. Ross is approaching 10 years with JDR Cables having worked in construction before that. He has worked with many OEM’s to bring new technologies into the industries and has recently provided input into a Carbon Trust Study into Inter Array Testing Technologies having used VLF & Damped AC on projects, and understanding the challenges that the environment presents. During the past 3 years he has supported HIGHVOLT with the development of their first Offshore Resonance Test system and overseen it’s delivery to JDR. The system is currently conduction AC Resonance Testing Offshore on a UK Windfarm.

Regarding a trustable windfarm internal grid the subsea cable plays an important rote. lt has to be well designed, produced, tested and installed. To perform retesting to determine the condition of the grid or locate faults some test results of the testing after installation shall be reproduceable without stressing the grid components. Challenges must be solved onshore, offshore components must be fitting and operational.

Detlef Herzog has studied electrical engineering with a focus on power supply at the University of Applied Sciences Wilhelmshaven. Since 1991 he then worked as grid engineer at EWE AG for electric, natural gas, telecommunication, drinking water supply and wastewater treatment grids. From 2005 to 2009 as electrical engineer in the power supply and renewable energ department of EWE AG (wind, solar, biogas power plants and emergency generators) responsible for development, construction, commissioning and grid connection of EWE owned renewable energy power plants. In 2007 with the alpha ventus project he started his offshore activities as Senior Electrical Engineer. In 2014 all EWE Offshore activities were transferred to EWE Offshore Service and Solutions GmbH (EWE-OSS). EWE-OSS in 2020 was transferred to Omexom Renewable Energies Offshore GmbH belonging to Vinci Energies.

In the recent years, offshore wind has become a cheap and reliable source of energy and forms one of the pillars of our future energy system. We are working to move forward on this way, supplying the offshore wind industry with the services and information they need.

Michel Greiner studied Mechanical Engineering at the University of Applied Sciences in Aachen and International Production Management at the Technical University in Hamburg-Harburg and graduated as Master of Science in 2007. Parallel to his study courses, he worked for the wind turbine manufacturer DeWind GmbH on optimization of mechanical subsystems and damage analysis of wind turbines. Following graduation, he served at German Certification Body DEWI OCC GmbH as mechanical engineer, but later focused on wind turbine rotor blades, production quality management and offshore wind farm certification. From 2016 to 2020, he worked for EWE Offshore Service & Solutions GmbH and was responsible for the wind turbine package of the offshore wind farm TWBII, ranging from initial contract negotiation to final wind turbine commissioning. After an internal transfer in 2020, Michel Greiner now works for Omexom Offshore as technical wind turbine specialist and deputy head of the newly installed Inspection Body.
