Meeting today’s demands As the sizes of wind turbines grow, towers need to be built bigger and made out of heavier structures. This means increasing heights, diameters and plate thicknesses, which naturally brings more challenges and a headache for the production line. In order to get the most out of the offshore winds, it is crucial for tower manufacturers to team up with an experienced technology partner that is capable of providing automated heavy fabrication solutions. During the past couple of years, welding and production automation providers have focused on developing advanced applications in order to meet the production demands of offshore foundations and towers. Today, offshore manufacturers are able to find extensive turnkey solutions that include each essential process, from plate joining and section assembly to implementation and production services. Enabling efficient plate joining When working with diameters this big, the challenge of having plates long enough becomes inevitable. Pemamek has gained extensive knowledge, in designing and implementing different types of plate joining lines thanks to 25 years’ experience in numerous shipbuilding projects. As a result, Pemamek has managed to develop and refine its technologically advanced plate joining solutions for the offshore wind energy sector.

Offshore wind will be one of the main pillars of India’s energy transition, as was proven in June 2018 when the Ministry of New and Renewable Energy (MNRE) set national targets for offshore wind power of 5GW by 2022 and 30GW by 2030. The first 1GW tender, expected to be launched off Gujarat later this year, has attracted some of the biggest international offshore wind players together with many Indian renewables’ developers. The spectacular cost reductions achieved by the offshore wind industry in Europe have attracted the attention of many countries, including India, interested in exploring offshore wind as a viable source of energy generation. Offshore Wind Consultants (OWC) and Tata Consulting Engineers have been developing a paper on India’s offshore wind outlook reviewing the policies and risks and presenting the key risks offshore wind developers and OEMs will face navigating the Indian offshore wind market. Among those risks, the study of soil conditions is a major driver for foundation and wind turbine generator designs and, hence, project economics. This article aims to summarise and shed more light on the soil conditions developers will find in the most advanced Indian offshore wind regions: Gujarat and Tamil Nadu.

The use of digital technologies such as cloud computing, big data management and predictive analytics are changing the status quo of the energy market. An increasing number of wind farm operators are starting to implement these techniques, so as to control their costs. But, if the implementation of predictive maintenance is one of your digital business transformation goals, how will you make sure it works? Early stage failure detection by real-time predictive analytics When talking about predictive analytics, one of the core features is detection. Beyond that, the real need is data reliability in order to detect failures and relevant anomalies to schedule a maintenance intervention. But, is the required wind turbine data quality good enough? Let’s start with an overview of the wind energy market grading. This analysis has been carried out by taking a representative sample of data coming from European wind farms. The following figure represents the wind industry grading mix from a typical European utility, which represents the sample for the analysis of this article. This grading takes into consideration the evolution of wind industry technology both, on turbine operations and the data variety needed for big data and predictive analytics services. 90% of the wind turbine technology mix comes from assets

Wireless technology brings the industry together Wireless technology has transformed the way we live. Every day, people depend on wireless systems to communicate at work, at home and when on the move. In fact, with advances in technology, it wouldn’t come as a surprise if in a few decades from now, we were all living in a virtually wire free world. The potential benefits of wireless systems for offshore applications are clear. Long-range radio modems and gateways have enabled people to communicate in even the world’s most challenging, far-flung seas. Through the development of its own patent-based communication products nCentric can offer disruptive technology and has a well-defined competitive advantage, both in term of technology and commercial contribution, compared to other competitive telecommunication technologies e.g. satellite and classic operators.

Offshore wind market is reliant on key global markets The offshore wind power industry continues to grow at a steady pace. It is expanding to new markets as cost reductions in the technology and demand for renewable energy become increasingly attractive to governments, power utilities, and other stakeholders. While the onshore wind market is larger in terms of total megawatt plant capacity added annually, offshore wind is growing quicker and offers a unique value proposition. It is an abundant clean energy solution for many coastal load centers where a greater proportion of population and energy demand is located—often areas where the onshore wind resource is more difficult to develop. Other key factors for offshore wind project development include higher wind speeds, higher plant load factors, more stable power generation, and rapidly declining costs. This article provides forecasts and insights into the offshore market through 2027. As of mid-2019, Navigant Research estimates there to be over 14.9 GW of offshore wind capacity in various stages of construction globally. This includes over 6 GW in China where, after years of delay, the offshore sector is reaching the massive scale expected of this market. The UK also has a large amount of capacity, with 4.8

The drivetrain of a wind turbine generator is an expensive but important component of the energy generating system. It’s composed of the main bearing, main shaft, gearbox, brake, generator shaft, and generator. The multi-physical complexity of this arrangement and the expense involved in downtime and maintenance due to failure, ensures that it is both recommended and normal for turbines to have several measures in place to monitor the health of the components. The most common remote monitoring systems are SCADA and vibration monitoring, collectively known as a condition monitoring system (CMS). SCADA offers an excellent approach for analysis of low frequency signals coming from sensors measuring temperatures, pressures, particle count, current, shaft speeds, and so on. A good analyst will filter the data and trend the results to look for anomalies across a wind farm, or to detect differences in data across a reference, for example, wind speed. Specifically, within a gearbox sump an oil particle count and temperature events at relatively low data rates can provide invaluable information regarding the wear of components and subsequent friction that would occur as a result of contaminated oil. A system will contain limit settings, that when breached will trigger an alarm and

As the world looks for competitive, zero carbon energy sources that can be deployed at scale and in relatively fast time frames, offshore wind is in greater demand than ever before on the world stage. The market will become truly global over the next five years. Capacity will grow, especially in Asia and the first largescale offshore installations are expected in North America towards 2022 or 2023. So, whilst currently, eight per cent of the new installations are offshore, we expect this share to jump to 22 per cent by 2023. To achieve or even exceed this growth ambition, we are focusing a large part of our activities on promising markets and providing guidance on wind potential, technical development and regulatory structures through the Global Offshore Wind Task Force. Chaired by Alastair Dutton and supported by offshore wind energy pioneer Henrik Stiesdal, the Task Force convenes some of our industry’s greatest minds on offshore technology, consisting of leading developers, investors and manufacturers in the sector, as well as technical experts and inter-governmental organisations.
