PES ESSENTIAL Implication of European/ German energy policy on the development of the wind industry Words: Urs Wahl, Energy Policy, VDMA Power Systems On a European level, two significant breakthroughs were achieved in energy policy during the summer: the European target for the share of renewable energies in the electricity supply will be increased to 32 percent by 2030. In addition, EU-member states are obliged to submit detailed plans by the end of 2019 regarding the deployment of renewables to contribute to achieve the EU-wide target of 32 percent.

The combination of larger loadsdedicated self-propelled feeder jack-up, the wind, places high demands on a jacking and increased flexibility, if not addressedNG-3750C as an alternative solution.At that time, when the future US pipeline ofwork was less visible than it is today, themain concern was whether a largeinvestment in a unit like the NG-9800C-UScould be justified. In response GustoMSCput forward the SEA-3250-LT as lower cost,non-self-propelled jack-up capable ofinstalling these same turbines (but notfoundations) at a minimum investment cost.The projected price was a ¼ to a 1/3 of theprice of the NG-9800C-US.Next generation solutionsWith time progressing, the expected sizeincrease of future offshore wind turbines isbecoming more and more apparent. Also,newly proposed lease areas of theMassachusetts and New York coasts are inincreasingly deeper waters, with waterdepths averaging over 45m and maximumdepths going up to 65m. Dedicated offshorewind turbine installation jack-ups for the USmarket, which have a lifetime of at least 20years, need to be able to cope with theseexpected future turbines and larger waterdepths. As such GustoMSC’s focus hasmore and more shifted to its next generationdesigns; namely the NG-20000X, theNG-14000XL and the NG-8000X.What these next generation designs allhave in common is that they apply jackingsystems on truss legs. The open legstructures provide reduced load andincreased stiffness in deeper waters, whencompared to circular leg designs. As suchthese designs are capable of working inwater depths of up to 60 to 70m meters.These units comprise a GustoMSCtelescopic crane with a capacity of 1,250mtin extended mode at hook heights ofapproximately 150m above main deck,thereby enabling the installation of nextgeneration (>12 MW) turbines. Where thesedesigns differ from each other is theirpayload capacity and crane capacity inretracted mode.At the higher end of spectrum (in terms ofcapacity), the NG-20000X is able to carry5-6 turbines and install foundations with www.peswind.com 17

Well-substantiated decisions can be made to replace components in good time. By adding ZF Wind Power’s unique ‘dynamic load monitoring’ sensor solution, it is possible to make sure that the loads applied to the gearbox are always within specifications – thus, avoiding damage and extending the operational life of the gearbox. Increasing the energy output The data from the ‘dynamic load monitoring’ sensor can also be used to increase the output of the turbine. By feeding this information into the turbine controller, active torque control can be used to increase the load on the gearbox maximally without causing any damage. This will help turbine owners get the most energy out during high wind conditions or at high grid demands. Digitalization and modularity for an optimized LCOE ‘SHIFT’, ZF Wind Power’s modular approach, goes hand-in-hand with digital technology to optimize the LCOE. The platform’s standardized building blocks offer more flexibility in gearbox development and it integrates intelligent gearboxes as digital solutions. The gearboxes contain integrated sensors that combine all the data needed to optimize the energy yields and operational costs of wind farms. Let’s illustrate this with an example of the loads that turbines might experience. Thanks to load monitoring data, we know which gearbox variants are needed on specific wind sites. ‘SHIFT’ lets you optimize the gearbox to site-specific loads or even mix the different variants at a single wind site. This way, project development costs will improve while the product lifetime increases. Cloud Access ZF Wind Power provides consumed lifetime calculations and analytics for drive train dynamics as a cloud service.

TALKING POINT Enhancing project returns through optimised deployment of wind monitoring technologies Words: Phil Horton, Managing Director, Dulas High-quality wind resource data is essential for investors and developers looking to guarantee the accuracy of financial modelling – all the more so as the decline in subsidy tariffs, both in the UK and further afield, leave little margin for error.

THINK TANKFigure 2: Wavelength of backscattered light (Source: Febus optics) The model consists of algorithms that simulate the fibre temperature along the power cable. The calculation starts with simulating the temperature response of the cable by calculating the heat generation in the cable, based on the measured cable load (time series of amps), the cable thermal properties and cable inductive and capacitive effects. In a following step, the heat propagation in the soil is simulated taking into account the cable surface temperature calculated in the previous step, the sea bottom temperature, the soil thermal and geotechnical properties and an estimate for the depth of burial of the cable. Next, the heat propagation in the soil and cable are combined to calculate the temperature at different points in the thermal chain, including the temperature at the fibre location.Figure 3: Block diagram of the Burial of Depth calculation model This calculated signal is compared with the actual measured temperature in the fibrethe constant amplitude of the Raman is a main drive of the total thermal (Figure 4).

In the middle of this box, one type ofoffshore power cable was positioned,which could be heated in a uniform way tosimulate the offshore power cable heating.Around the cable, at various distances fromthe centre, thermocouples were installed tomeasure the temperature of the soil.Furthermore, thermocouples were installedinside the power cable. During theexperiment, the heat generation in thecable was controlled and varied while thewater was kept at a constant temperatureof 4°C. By doing so, the heat propagationthrough the soil could closely be monitored.The experiment was repeated for differentburial depths, by changing the height of thesoil package on top of the cable and fordifferent soil types by changing the soiltype in the box from fine sand to verycoarse sand.The measured temperatures inside thecable and at different distances, were thencompared to the outcome of CFD-modelsand our model algorithms.
