The fundamental standards for manufacturing semiconductors and solar cells are as concise as they are clear – they demand absolute protection of people and the environment against chemicals, while simultaneously protecting ultrapure chemicals from contamination. Lately of course, the requirement for highly efficient processes has been added. It is surprising that still little is known about how this can be achieved simply and economically by using modern dispensing systems. And in addition, there is potential for substantial savings during the various process steps. Dispensing chemicals more quickly, more safely and more efficiently There are very good reasons why the QC-System, produced by AS, has emerged over decades as one of the leading dispensing systems worldwide for ultrapure and aggressive chemicals. Customers including prestigious chemical manufacturers and end customers in various industrial sectors benefit from a highly flexible precision tool in more than 100,000 variants for almost any imaginable operational purpose. It is completely free of metals and made from 100% ultrapure, high-performance plastics, including a patented coding system that prevents product mix-ups. It includes a Quick-Connect System, every last detail of which is designed to maximize safety and purity during production. The QC-System: many ideas for maximum safety The QC-System undergoes continuous further development and improvement to

Leonardo Botti, Global Head of Product Management ABB, reviews the impact of Blockchain and how digitalization can support the technology’s adoption. In 2009 a new disrupter finance model was launched- BitCoin. It heralded a new era in how currency and transactions were made and transferred globally. The emergence and rising popularity of this new cryptocurrency market reached a defining point in 2017 when the number of B2B enterprises adopting Bitcoin trebled and suddenly attracted the attention of global investors. But what does this decentralized digital currency have to do with the changing energy market? To answer this question we need to look at the technology that underpins BitCoin - ‘blockchain’. Blockchain is based on a peer-to-peer platform that has created new ways in which we can transact with one another. The underlying transaction model moves us away from a centralized architecture towards a more direct and decentralized system between peers. This reduces the need for a central server, authorization and authentication of transactions by one single authoritative body. For the energy market, it is presenting new opportunities for innovation within utilities and amongst homeowners. It is redefining how our energy is supplied and potentially creating a sustainable energy community. Role of the prosumer Energy transactions

The renewables market, particularly wind, is a key sector for ALE. Building on experience in the power sector, we have used our knowledge and expertise to develop smarter solutions to the challenges created by the increasing heights of wind turbines and associated components. In relation to the on-shore wind enery market, ALE offers a bespoke Transport, Crane and Installation (TCI) package for the wind energy sector. The transportation phases of projects include route assessments, liaising with local authorities, providing specialist transportation equipment and facilitating the removal and replacement of any street furniture or structures that may obstruct the route. We own a fleet of specialised equipment that is specifically used for projects in this sector, such as ` blade trailers and low profile wind tower adapters. Our qualified electrical and mechanical installation teams have the knowledge and experience to provide the most efficient solution, on a project by project basis.

Times have changed over the last 50 years in our industry. PES has had the pleasure to witness the ever improving quality, health, safety, environment (QHSE) implemented in company policies both on and offshore. Read on to find out what is happening at Glomar Offshore. In Glomar Offshore, as an owner and operator of 20 offshore support vessels, varying from, lower end of the market: guard vessels, to standby safety and Emergency Response and Rescue (ERRV), to high specification, subsea and offshore accommodation and access units, we deploy our fleet in both the Renewables and O&G industries on approximately a 50-50 ratio. Whilst these two sub segments, constituting the bulk of activities for the median Northern European ship owner, alongside dredging, salvage and governmental/institutional support, are considered quite distinct, this is far from reality. As such, the experience, QHSE record, skillset and technology used are the same. In our industry, it has to be in every company’s policy to prevent incidents in all activities carried out by the shore-based and shipboard personnel. This includes external personnel, subcontractors, as well as assets from third parties employed for a specific project. All companies should aim for a culture of commitment to safety, accountability and responsibility. Safe

PES is delighted to bring you this latest advanced technology solution from ZF Wind Power. Over the last few years total wind turbine noise, which is mainly generated by the interaction of the wind and the wind turbine structure, has changed from being one of the properties of a wind turbine to a true differentiator between different wind turbine OEMs: the less noise the wind turbine generates, the more wind turbines can be placed on the same piece of land without violating the prevailing noise regulations. To achieve this, wind turbine OEMs are investigating among other things reducing overall noise levels by utilising optimised low noise blade design using e.g. serrations and improving controller strategies to include a wide variety of low noise modes. As the overall wind turbine noise is used to mask the noise coming from the mechanical components inside a wind turbine such as the generator and the gearbox, these noise sources also need to be optimised. The low noise blade designs, which are still being studied, have a direct impact on the overall wind turbine noise and thus require the mechanical noise to be reduced at the same pace. Next to that, the increased number of low

Following the recent news, widely published in the industry and national press regarding a number of offshore wind farms, it seems that last year’s end of warranty inspections highlighted unprecedented amounts of offshore wind turbine, blade leading edge erosion, across several offshore wind farms in Europe. As the offshore wind industry enters the 2018 season blade repair campaigns, there is much to be considered. Early intervention is imperative for the quality and longevity of repairs. PES asked WTG to give us their view on this problem. It is an issue the industry has long been aware of and there are many initiatives in place looking to tackle the issue, such as the Offshore Renewable Energy (ORE) Catapult’s Blade Leading Edge Erosion Programme. Is this the Benchmark for future blade inspection and Integrity management during warranty? The following extract applies: If the expected lifetime of the surface coating is less than the lifetime of the blade, suitable inspection and maintenance intervals should be specified. Inspection and maintenance intervals shall be planned to provide adequate assurance that no significant deterioration in the condition of the installation may arise in the interval. The design should take into account the practicability of carrying out inspections of relevant components

S&P Global Ratings rated its first onshore wind project in 2003. Since then, the renewable energy sector has undergone tremendous expansion. In the past decade alone, its compound annual growth rate has totalled 20%, thanks largely to the rising awareness of how using fossil fuels for power generation contributes to climate change. In Latin America in particular, where most renewable capacity comes from large hydro plants, onshore wind power sources are playing an increasingly important role. Oaxaca, a region in Mexico, for example, is considered one of the best regions worldwide for onshore wind farms. Its geological formation creates a corridor with consistently strong winds. So, the favourable wind resource, in combination with lower operation and maintenance cost, resulted in the upside of the credit outlook in the region. A global outlook Last year alone, onshore wind added approximately 53 gigawatts (GW) to the global capacity grid – bringing the total to around 540 GW. This is partly due to higher capacity factors and falling prices throughout the wind turbine supply chain, both of which are fostering onshore wind power’s rapid development. However, the sector’s growth isn’t without serious challenges. Wind resource availability has often failed to live up to the initial estimations made
