The latest UAV (unmanned aerial vehicle) technology allows swift, thorough inspections to assess turbines. Drones can be used either as part of routine reporting or for detailed inspections in preparations for rope access teams. This has many significant health and safety benefits for the technical teams in terms of assuring all anchor points are secure and preparing in advance for any repair work that will need to be done at height. Here, UAVONIC Ltd, shares the fundamentals of a typical aerial inspection and how wind O&M teams can benefit. UAVONIC works closely with inspection engineers to give the UAV Operators a good understanding of the wind turbine’s structure. So when on site with a client, pilots can understand the issues most commonly discovered upon inspection and what is required for the inspecting Engineer. When doing an inspection on a wind farm usually an inspection Engineer from the site would be present with the UAVONIC UAV team. There may be specific issues he is already aware of that he will want the pilot and camera operator to focus on, but all project plans will look similar consisting of the following scope of work:

Words: Thomas Arnold and Thomas Zirngibl, TÜV SÜD Industrie Service GmbH The recently revised TR6 Technical Guideline of the German Public Association of the Renewable Energy Sector (Fördergesellschaft Windenergie (FGW)) is designed to ensure the provision of reliable yield forecasts. Wind reports based on the Guideline play a critical role for producing reliable estimates of the profitability of a wind-farm project. In the past, turbines have often been shown to deliver lower energy levels than their reported estimates. The ninth revision of TR 6  now specifies methods that will help to produce realistic forecasts of actual on-site wind conditions. Wind speed and direction at the proposed site of a wind farm are critical factors in determining whether wind farm operation will be cost-effective over the long term. Previous practice has shown that measurements and evaluations of wind and weather data may be over-optimistic, favouring the stakeholders’ own interests. At least two wind reports issued by third-party organisations are therefore necessary to convince banks and investors of the profitability of a wind-farm project in order to secure financing. Independent accredited assessors are therefore commissioned to verify the yield forecast of a planned project. As these forecasts are always based on varying project-specific facts, figures

PES talks to Rick Huntley, Director of Safety and Compliance, at Sentinel Aviation and discovers exactly how important safety is in this company. Two of the directors are ex-military and bring this added experience. He also explains that this relatively new industry is already entering a cut throat price war due to the number of players in the market. PES: Welcome to PES Wind magazine. Thanks for talking with us. Would you like to begin by explaining a little about the background of your organisation and how you currently serve the wind industry? Ricky Huntley: My two fellow directors established Sentinel Aviation in 2014 to exploit opportunities in the Unmanned Aviation Systems (UAS - drone) sector. One of the directors spent 18 years in the British Army before leaving to become a commercial pilot, flying corporate business jets, bringing a wealth of military and commercial aviation safety and risk management processes to the business. The other director founded and built a leading environmental contracting company, which required the highest levels of safety and risk assessment practices when working with the country’s largest energy providers on very high profile energy, nuclear power infrastructure, railway and motorway projects. Safety and risk reduction is an

Words: Lindsay Roberts, Senior Policy Manager, Scottish Renewables Renewable energy is now our largest source of power and with over 5.5GW installed onshore, wind provides the lion’s share of that capacity. Can the Scottish and UK Governments work with industry and regulators to remove a series of barriers as suggested in a report by Everoze and explained here by Lindsay Roberts, Senior Policy Manager at Scottish Renewables? The sector has delivered hugely impressive cost reductions, leading some commentators to claim that it is already the cheapest form of new electricity generation plant on the market. It’s perhaps not surprising then that the appetite for further development remains undiminished, with another 7GW of capacity waiting in the wings. That pipeline, however, faces an uncertain future without a viable route to market. What is certain is that a successful future depends on our ability to reduce costs even further. Earlier this year (2016) Scottish Renewables commissioned energy consultancy Everoze to examine just how low the cost of onshore wind in Scotland could go and the steps needed to get us there.

The Dutch Government’s offshore wind energy programme is making significant waves in the energy sector, after Dong Energy bid a record-low price for the contract to build and operate the first two projects offered in the country’s five-year tender programme. That could only happen because of the steps taken by the State in designing an offshore wind plan and tender system that alleviates risk for the industry, as Ruud de Bruijne, Project Manager, Offshore Wind Energy, Netherlands Enterprise Agency (RVO.nl) explains. Under the Netherlands Energy Agreement for Sustainable Growth, the Dutch government has set a target of 14% of all energy to be generated from renewable sources by 2020, rising to 16% by 2023. Offshore wind power is central to achieving that and, as a country, we are determined to make the Netherlands a leading force in the sector. Under our Government’s plan, there should be 4500 MW of offshore wind plant operating in the Dutch North Sea by 2023, up from the 1000 MW currently operating or under construction. Specifically, the plan will see 3500 MW of new capacity installed across two wind farm zones (Borssele and Hollandse Kust), broken down into five 700 MW tender rounds. Critically, the plan actively

The Race Bank Wind farm is being constructed by DONG Energy approximately 27 kilometres off Blakeney Point on the North Norfolk coast and 28 kilometres off the Lincolnshire Coast and Chapel St Leonards. It covers an area of 7511ha. Export cables bring the power from the wind farm to the substation onshore. These export cables run through the Wash and come ashore east to the mouth of the river Nene and approximately 6 km northeast of Sutton Bridge. The cables ashore run further in a southerly direction to the connections point at the existing Walpole Substation. The two export cables are both approximately 70km long and the two Offshore Substations (OSS) are linked with an interconnector of 4km. In March 2015 Jan De Nul was awarded a contract for the installation and burial of both export cables and the interlink cable.    Here we focus on the installation of the intertidal parts of the export cables and its special challenges. Environment The intertidal areas of The Wash compromise up to 10% of England’s saltmarshes and form one of England’s most important natural habitats. Mitigating any potential for the installation works to impact on these habitats is a key priority and measures to ensure that works
