Power & Energy Solutions

The premier renewable energy publication

The price per megawatt used to be the sole decision-making criteria in sustainable energy sources. Now the tide is beginning to turn – the whole energy value chain needs to be taken into account when assessing feasibility. Power purchase agreements are on the rise. Most active are those energy intensive players who see sustainability and a low carbon footprint essential for their future business success. Many of them have an ambitious goal to use renewable energy sources only. You might argue that this is something that is reserved only to the big boys such as Google, Facebook and likes. But be assured, the rest of the business will follow these trailblazers. Call it good corporate citizenship, call it sound business sense. The fact remains the same; there is a growing demand for low carbon footprint energy solutions. For example, Facebook has signed a 294 MW wind power purchasing agreement with Vattenfall. The power for their data centres in the Nordics will come from the Norwegian Bjerkreim wind farm. ‘Bjerkreim wind farm is built on our rock foundations, which will help Facebook to reach their renewable energy goals,’ says Kari Tuominen, the business director for Peikko wind turbine foundations. Google is also a prime example. ‘The 148

The combined expertise of DNV GL and WeatherTech will enable the development of an innovative new icing model, which can be applied globally to better predict the performance of wind turbines in cold climates Stockholm, Sweden - 13th September 2018 – DNV GL, the world’s largest resource of independent energy experts and certification body, today announced that it has joined forces with Swedish atmospheric science experts, WeatherTech. The combined expertise of both companies will enable the development of the most advanced icing model for wind turbines available on the market, allowing customers to better predict the performance of turbines in cold climates. In cold climates, the performance of wind turbines is significantly reduced by ice accretion, the gradual build-up of ice on the turbine blades. The impact of ice on turbine performance is a major challenge for developing and operating wind farms in cold climates, where production loss can exceed 50% during winter months, and surpass 10% over the course of a year. WeatherTech enjoys a renowned reputation in the Nordic wind resource market and is one of the specialist companies at the forefront of cold climate issues. The partnership between DNV GL and WeatherTech will enable innovation in the renewable energy

Maritime transport company Meriaura Ltd. has signed a long-term contract with Aalto Shipping Company Ltd of time chartering dry cargo vessel ’Airisto’. M/V Airisto’s capacity is 8700 tonnes and 12700 cubic meters. She is significantly larger than the vessels operated by Meriaura until now. Because of her large cubic capacity, the ship is suitable especially for large volume bulk cargoes, such as various biofuels, wood and sawn timber. The ship has two separate cargo holds and partial tween decks that allow transporting of part cargoes and project cargoes. "With this vessel type we respond to customer needs and to changing material flows in the Baltic Sea. Carrying products of bio and circular economy has always been part of the core business of our company. Now we are able to carry larger cargo quantities,” says Beppe Rosin, Vice Managing Director of Meriaura Ltd. The long-term time charter arrangement complies with the strategy of Meriaura Group. The strategy is based on a mix of owned tonnage and long-term time charter contracts. “Expanding our fleet is a clear target. We are continuously looking for potential candidates for purchase or time charter, also the in size of M/V Airisto”, comments Beppe Rosin. MV Airisto will be delivered

Aberdeen, September 13th, 2018: This year the UK-office of Deep Sea Mooring (DSM) - a Vryhof company - has considerably strengthened its presence in the offshore energy hub Aberdeen, Scotland, with the opening of a strategically extremely convenient deep water quayside facility. This follows the opening of the UK office in April 2017. The Port of Aberdeen is an economic driver for the whole region. As a global leader in providing secure, innovative and high quality mooring solutions to mainly E&P (exploration and production) companies and drilling operators, DSM’s aim is to become a strong local partner for its international clients in that area, by delivering excellence in the broadest sense of the word. The office is headed by UK Managing Director Mo Tafazzoly and was established more than a year ago in response to growing demand for DSM’s services and solutions, across the North Sea. “We started our search for a suitable base in the middle of last year and are very pleased to have found this unique facility with indoor and outdoor storage areas,” said Mo Tafazzoly. “There is minimal impact in terms of tidal dependency.

Berlin/Varel, 13 September 2018. The Federal Maritime and Hydrographic Agency (BSH) has announced that in future it will no longer be necessary to periodically renew the yellow full-surface paint covering the substructures of offshore wind turbines. The agency considers the requirements for the initial coating to be sufficient to comply with international recommendations and standards. The markings are intended to increase maritime safety. Generally, all offshore installations had until now been required to undergo inspections for damage to the paint coat and compliance with colorimetric requirements in accordance with the specifications of the Directorate-General for Waterways and Shipping (GDWS). Non-compliance with these specifications would result in mandatory repainting of the substructures concerned. In the BMWi funded project "Implementation initiative of cost reduction potentials in offshore wind energy (UKOW)", German Offshore Wind Energy Foundation – in cooperation with industrial partners – investigated expected costs, prepared risk analyses and conducted comparative international studies. The anticipated costs for required repainting of existing offshore wind turbines in Germany were estimated at up to 400 million euros. In addition, the foundation had the benefits of the yellow paint cover for marine traffic investigated by a DNV GL study. This study demonstrated that marking the foundations with yellow

ZF is a leading pioneer in cost-efficient wind turbines. The reduction of Levelized Cost of Energy (LCoE) is their principal aim. The SHIFT platform concept means it’s now possible to optimize gearboxes for specific-site loads. PES wanted to know more. LCoE of wind energy happens with big evolutions in wind technology. Big is important. There are a couple of ways to produce more power from the wind in a given area. The first is with larger rotors and blades to cover a wider area. That increases the capacity of the turbine, i.e., its total potential production. The second is to situate the blades higher, where the wind blows more steadily. That increases the turbine’s ‘capacity factor,’ i.e., the amount of power it actually produces relative to its total potential. The more variable a source is, the more backup is needed to firm it up and make it reliable. By making wind less variable and more reliable, higher capacity factors reduce backup costs. With increasing capacity factors wind can spread its energy out over a longer period, easing wholesale price pressure during low demand. By extending its hours of operation, a high-capacity-factor turbine is more likely to be producing during demand peaks, when power is
