In this, first of four articles, we look at how ActSafe Powered Ascenders are making wind turbine maintenance quicker and more efficient. We are all familiar with the adage “time is money”, and in offshore wind energy nothing could be more true. Getting people and material onsite quicker and allowing work tasks to be completed more efficiently can save thousands of euros per annum. ActSafe Powered Ascenders are helping to make wind turbine construction and maintenance cheaper by enabling personnel to get themselves in difficult to reach places and manage tools and components more easily, saving both time and material costs. Personnel access and work positioning In wind energy, it is imperative that maintenance and construction personnel can reach their place of work. The technicians need to be able to perform tasks, as efficiently as possible, to reduce work time and get tasks completed during available weather windows. Although many tasks can be performed from existing access platforms, there are still some areas of a wind turbine that are difficult to reach. These include; The interior of the transition piece The exterior of the nacelle The exterior of the spinner Wind turbine blades The exterior of the tower Some areas of the interior of

Offshore wind turbines suffer from severe corrosion and with limited access to them, the choice of the right corrosion protection is crucial. The most widely used protection methods are anti-corrosion coatings, often in combination with cathodic protection (in the submerged zone). However, these coatings often suffer from premature failure due to mechanical damage, application errors or the wrong choice of coating system. (Insert image  failure of original coating in atmospheric zone). These failures need to be addressed during service life to ensure the integrity of the structure. The lack of accessibility results in high repair costs up to €2000 per m². Therefore it is important to choose a high performance repair system that will last for the remainder of the service life and can easily be applied in the extreme conditions encountered offshore. The high repair costs should be reduced by selecting a system which saves on surface preparation and application costs. This translates directly in a coating that is surface tolerant and reduces the amount of layers. Another concern is the environmental impact of offshore wind farms. Wind turbines are known to create disturbances (e.g. increased noise levels) that affect marine life. The environmental impact of the corrosion protection should be considered

A new innovative approach to windfarms could, at last, make them more popular and community friendly. Bringing the benefits and the profits home to local communities. Daniel Dubbelhuis, Account Manager Netherlands at Lagerwey tells us how. Large multi megawatt parks in concentrated areas developed by and for the local community, anonymous big developers - ensure further anonymization of wind turbines. Local residents feel that they get saddled with a problem that they have not asked for, resulting in a growing resistance to on land wind turbines. The last 10-20 years have shown how not to develop wind projects. The parties ultimately end up in court, each trying to get their own way. In the meantime sustainable energy becomes a conflict between developers and local residents. Why do we develop both large and small wind farms in this way? Why with each project achieved do we create more resistance to wind power? Shouldn’t the sustainability aspect also be reflected in the relationship between all the actors in a project?

SgurrEnergy, part of Wood Group’s clean energy business, has supported the 115MW Santiago Solar PV plant in Chile to financial close. The leading renewable and grid integration consultancy was appointed by Santiago Solar S.A. to undertake technical due diligence during the financing period at the site which is located in Til-Til, Santiago.  SgurrEnergy’s scope of work included site assessment, project schedule review, equipment and technical design reviews, independent solar resource assessment and energy yield prediction. The team of engineers and consultants also undertook a review of grid connection arrangements, engineering, procurement, and construction (EPC) and operations and maintenance contracts, technical inputs to the financial models and provided ad-hoc support to the project lenders before moving on to the construction monitoring phase of the project Vincent Burgmeier, consultant at SgurrEnergy, said: “SgurrEnergy is delighted to have supported the Santiago Solar PV project to financial close. This is one of a number of key projects being delivered in Chile and we’re looking forward to supporting the project through the construction phase, on its road to operation.” The Santiago Solar PV plant which is owned by EDF Energies Nouvelles (50%) and Andes Mining and Energy (50%) will be constructed throughout 2017 and is estimated to commence operation at the end of

GRS Global Renewables Shipbrokers, OWS Off-Shore Wind Solutions and A1 Offshore Solutions announce the Sale of the DP2 Walk-to-Work Vessel OCEAN ZEPHYR. GRS has developed and arranged the sale of OCEAN ZEPHYR (incl. Ampelmann A Type) from Emden based OWS Off-Shore Wind Solutions to Denmark based A1 Offshore Solutions. The delivery took place on the 24th of March 2017 in Emden and the vessel will continue a charter for a German Wind Farm under its well-known name OCEAN ZEPHYR. The OCEAN ZEPHYR is the first DP2 Walk-to-Work Vessel in the fleet of A1 Offshore Solutions. Her long solid track record and proven capability over the last four years within the offshore wind business matches perfectly with the excellent track record of the new owner A1 Offshore Solutions and their existing fleet of PSVs trading currently mainly on German Wind Farm projects. OWS Off-Shore Wind Solutions has been very happy with the proceedings of the sale and with the performance of Global Renewables Shipbrokers as well as with the buyers. “We are happy that the GRS driven Tender Sale Process could obtain this high interest in the market for our divestment of the Ocean Zephyr”, said Sellers Management. “This purchase is part of our

Hamburg, 5 April 2017. The Nordex Group is widening its range of efficient solutions for medium and light-wind locations with the addition of two new models. The N131/3900 is an enhanced version of the N131/3600 from the Generation Delta range. With the N131/3900, Nordex is raising the nominal output of its most powerful light-wind turbine by 8 percent, thus enabling yield gains of between one and four percent to be achieved depending on the location. Despite the increased output, acoustic emissions could be kept at low106.2 decibels by using serrations at the rear edges of the blade. Moreover, noise-optimised operation modes are available for the turbine, meaning that it can also be used in sound-sensitive locations. Nordex is offering the N131/3900 with hub heights of up to 134 metres. The turbine will be available in North America as well as large parts of Europe from January 2018. The first N131/3900 will be installed in Germany at the end of 2017.
