Renewable energy, primarily wind and solar, will represent the largest source of electricity growth over the next five years, driven by falling costs and aggressive expansion in emerging economies. Globally, progress continues to be strong with increasing annual installed capacity and investments. As solar power becomes more economical, wind systems have to become competitive to continue to grow. Consequently, development of new technologies which reduce turbine maintenance and life cycle costs, improve reliability and lower levelised cost of energy (LCoE) will result in wider adoption of wind power generating systems. LCoE is one of the utility industry’s primary metrics for the cost of electricity produced by a generator. Key inputs to calculating LCoE include capital costs, fuel costs, fixed and variable operations and maintenance (O&M) costs, financing costs, and an assumed utilization rate for each generator. Wind asset operators understand that O&M costs must be minimized to maximize energy generation. Thus, turbine reliability and high energy throughput are a critical measure of wind generation. Although all components in a wind turbine must work reliably, a turbine’s wind pitch system, whether electric or hydraulic, is a key component required for optimum blade pitch control under adverse wind conditions; to maintain turbine

After a difficult period, the heavy lift industry is making changes and diversifying. PES finds out how one such company is meeting the challenge head on. All the know-how and expertise is already in place for what looks like the beginning of a heavy lift revival. HANSA HEAVY LIFT, which specialises in heavy lift, super heavy lift and project cargo, is stepping up its involvement in the offshore industry with a strong focus on transportation and installation (T&I) in the subsea oil and gas market, as well as the offshore wind farm sector. Wholly owned by the investment company Oaktree, the shipping line manages a fleet of 17 vessels and operates a dynamic positioning class 3 (DP3) construction vessel, which is ideally suited for offshore installation projects. With the heavy lift industry in a state of flux and still recovering from a period of overcapacity, HANSA HEAVY LIFT sees much potential for the future in the offshore T&I market. The carrier notes there was a steep drop in investment in the project and heavy lift market in 2016, and very little activity going forward for new projects.

For the past 3 years, ALL NRG has combined the strengths of several leading Danish energy service providers to create a solid base for further development. PES went to find out how this has been achieved and why there is optimism in the air. Collecting industry know-how from its individual business segments, such as high voltage, mechanical wind, and inspection and advisory services has given ALL NRG the strength to develop their business in the right direction to respond to the latest market conditions. Until recently, the market consisted of smaller service providers offering fragmented solutions to manufacturers and developers in the wind-power industry. Now companies are gathering their forces as the market demands a turn towards large tender processes and full scope projects. In addition, the increasing demands for higher Health, Safety, Environment, and Quality (HSEQ) levels has made it difficult for smaller companies to compete. First mover Even though the ALL NRG name is still fairly new to the industry, the companies behind it are far from newcomers to the business. The integrated ALL NRG has a list of references with which it is hard to compete. Having worked on more than 90% of the world’s municipally sponsored offshore wind turbines, the

Words: Peter Hearn, Operations Manager, ActSafe In this, second of four articles, we see how ActSafe Powered Ascenders can be used for material lifting in the wind energy industry. What is an ActSafe Portable Powered Winch? A Portable Powered Winch is a Li-ion battery or petrol powered lifting apparatus that is certified for lifting both loads, personnel and for lowering operations. The winches use readily available, 11mm kernmantle ropes so only rope length limits the lifting distances. The Working Load Limit is 200 and 250kg so these winches are a flexible tool that makes it possible to lift a wide variety of cargo and facilitate positioning operations. Nacelle In wind energy maintenance time is money, particularly when offshore, where weather windows are short. What happens when your crew arrive onsite, with a restricted time opportunity to get the turbine back online and they are unable to get tools and material into the turbine because the installed lifting equipment is not fit for purpose? An Actsafe portable battery powered winch, with a lifting capacity of 200Kg will ensure your maintenance teams can complete the task. This will reduce the risk of prolonged downtime. It also means it’s not necessary to have a permanent chain hoist fitted to

In October 2016 PES brought you the newly baptised Vol au Vent. It has certainly been a winner for Jan de Nul, with ongoing projects and planned improvements to increase the crane’s capacity and available deck space. The Blyth Offshore Demonstrator Project During the third quarter of 2017, Jan De Nul Group’s vessel Vole au Vent will start the installation of 5 MHI Vestas 8.3 MW turbines at the Blyth Offshore Demonstrator Project. This new project is located 5.7km off the coast of Blyth, Northumberland, UK. The Jan De Nul Group was awarded the contract in March 2016 after FID was achieved by EDF Renewables UK. The Blyth Offshore Demonstrator wind farm will have an initially installed capacity of 41.5MW of electricity, which is enough to provide approximately 34,000 homes of renewable energy. Third in a row This project will be the third project in a row for the Vole au Vent since it was acquired by Jan De Nul Group in 2015. The previous projects were the Bligh Bank Phase II project and the Tahkoluoto project in Finland. By the time the new project starts, the two previous projects will have been completed.

The demand for safe, clean reliable renewable power is growing at an ever increasing rate. Today PV technology is not only ecologically, but also economically a sensible alternative for power generation. A large scale PV power plant has to be competitive against conventional energy sources as well as other PV projects. With the elimination of government subsidies for this kind of energy generation in many regions and markets, the focus has now shifted to the plant’s overall efficiency. In the face of increasing cost-consciousness within all industrial sectors, the downward pressure on costs as well as on BOS components (balance of system) are becoming more and more crucial. Due to this, profitability has been lagging, so companies try to optimise CAPEX costs mainly and safe money on these components – often even during the design phase. But the real keys to improvement are both better capital and operational efficiency. The determining factor concerning favourable conditions for investment loans and credits is the profitability of a project during the operation period on the basis of reliable partners, components and an adequate operation and maintenance. When it comes to the profitability and the return on investment of a PV project, a low LCOE
