Proper and effective operation and maintenance (O&M) management of wind energy is crucial to the energy yield of the wind farm. Lowering the cost of O&M is becoming more of a challenge and at the same time, a necessity for the modern and competitive wind energy market. Daniel Perkowski, CEO at Wind Audit sp. z o.o., Szczecin, Poland shares his ideas with PES on how to achieve this. A wind turbine, as any complex high-tech device, should be adequately maintained in order to do its work safely and with maximum efficiency. Some good practices in maintenance management can reduce the overall cost of the O&M, meaning less lost energy production and to ensure that a wind power plant is in tip top technical condition. Regular preventive maintenance The regular service of wind turbines is the primary preventive thing to do. It is performed once or twice a year, depending on the manufacturer and type of wind power generator. During preventive maintenance services, there are things done, in accordance with maintenance service checklist. These include: hydraulic filters replacement, pressure measurement, battery exchange, electrical measurement and so on. As a result, the wind turbine is maintained at an appropriate level, which may or not be

Synergies are better than my way or your way. It is an efficient combination and results in our way. The last years in the offshore wind industry, which is similar to oil and gas, have shown that each project and/or location has its own, individual logistic concept and needs an exclusively chartered vessel or even vessels. To reduce cost and increase efficiency this concept has to be questioned. Alternative solutions such as vessel pooling or shared logistic runs might be an alternative option to establish. First concepts are on the trial and wind park owners are willing to forward responsibilities to their suppliers having more clients and therefore the possibility to share vessel cost over a few projects. Looking back to the beginning of offshore wind, specialised vessels were rare and mostly found in the oil and gas industry. The high priced tonnage made it difficult for the wind farm owner to find an economical business plan in other words - the whole industry was pioneering its way through the tangle of the offshore wind jungle. Subsidised parks were developed and soon became the test areas for all kind of trials. Starting with simple environmental experiments, on site as well as onshore and with

Six years ago, ZF Wind Power took the challenge to set the benchmark in the industry pioneering wind gearboxes to power the new giants of the sea. The project started with an early cooperation between the customer and ZF with one main focus: reliability. Dr. Dirk Strasser, Manager Wind Gearbox Design at ZF Wind Power, Witten, shares his reflections with PES, on the project from an engineering perspective and points out the resultant benefit for the customer.. Development projects for the wind industry usually are characterised by short development times and gearboxes developed to specification. The 8 MW development started with a different focus. A reliable drivetrain at competitive costs was the objective, with reliability being recognised as one of the most important contributors to the turbine’s competitiveness. Before starting detail design, ZF cooperated closely with the customer in order to cover all gearbox requirements in the interface specifications. This means, on the one hand, a sound mechanical design on the rotor side, delivering a mechanical torque of minimum 8,000 kNm whilst keeping parasitic loads small, and on the other hand, meeting mechanical and electrical requirements on the generator side prescribed by the integrated drivetrain layout.

While German wind turbine manufacturers have become active in nearly all markets in the world, in Germany it is facing a profound upheaval. Now that renewable, decentralised energy transition technology has become a major pillar for power generation in this industrial nation. Matthias Zelinger, Managing Director of the Power Systems trade association and VDMA (German Mechanical Engineering Industry Association) gives PES the benefit of his insight. Since the beginning of the year the federal government has started organising the expansion of new installations by implementing a tendering system, following a major, international trend. This increases competition and cost pressure, along the process chain. At the same time, they are striving to achieve fair conditions on the world market and develop a new integrated energy system in Germany. The expansion of wind energy in Germany was very successful over the last three years. 2016 saw a capacity increase of approximately 4,600 megawatts onshore and 800 megawatts offshore. With more than two gigawatts going online, 2015 was a record year for offshore wind energy. The reason for this great leap was in fact due to a delay: the completion of a number of offshore grid connection points in 2015 meant that an unusually large
