UK subsea services company, Rovco has announced the successful completion of an underwater survey of the Amazon Reef, off the northern coast of Brazil, for leading environmental organisation, Greenpeace. The Bristol-based firm carried out a full 3D seabed survey, deploying its SubAtlantic Mojave and Seaeye Cougar ROVs while using its latest 3D reconstruction technology. The project also required Rovco to mobilise a survey grade, fully redundant Ultra-Short Base Line (USBL) system for accurate subsea positioning. Findings revealed the existence of coral reef near the mouth of the Amazon, which extends further than previously thought. The calcareous ecosystem which supports fish and other reef creatures lies inside a recently licensed exploration block, approximately 28km from an exploration well in the Foz do Amazonas basin. The project was completed within six weeks by Rovco’s survey party chief, ROV supervisor and ROV pilot on-board the Greenpeace Esperanza ship. The mobilisation took place in Bordeaux, France, and work commenced offshore Brazil before concluding in French Guiana. The demobilisation will be conducted in La Rochelle over the coming weeks. Rovco is already in discussions with Greenpeace about using similar 3D survey techniques to protect other sensitive environments around the world. Brian Allen, chief executive and founder of Rovco, said: “We

range for global offshore – number of offshore wind farms is growing Hamburg, 14 June 2018 – The offshore sector of the wind industry has made headlines in recent months. It has progressed rapidly, both in technical innovation and in the competitiveness of offshore energy in the electricity market. Many of the companies active in the offshore wind market are presenting their portfolios at WindEnergy Hamburg, the world’s leading expo for onshore and offshore wind energy, from 25 to 28 September. The expo will be held in parallel with the global conference of WindEurope at the Hamburg Messe site – together they comprise the Global Wind Summit, the biggest and most important meeting of the wind industry worldwide. WindEnergy Hamburg is expecting some 1,400 exhibitors from all parts of the world, with about 40% of them showcasing products or services for offshore wind farms. The range covers the whole of the value chain, from turbines, towers and foundations to gearboxes, generators, bearings, shafts and lubes to O&M solutions and installation vessels. Global world market growth Besides main offshore wind market Europe, other geographical regions of the world might start experiencing quick growth too in the next years says GWEC in its 2017 Global Wind Report.

Paramedics will be working on two offshore wind projects off the East of England coast in new contract awards for pioneer SSI Energy. The first company to supply highly-trained life-saving dual role technicians has won its first long-term offshore contract as part of the operations and maintenance team on the Greater Gabbard Offshore Wind Farm (GGOWF) off the east coast. The company has also landed a contract to supply paramedics during construction of the 714MW £2.5bn East Anglia ONE with renewable energy vessel specialist Turner Iceni after the success of its offshore wind contract on the Galloper Offshore Wind Farm construction. Employing the paramedics, who have undergone technician training, means lives can be saved offshore in the “golden hour” in medical emergencies such as strokes, heart and asthma attacks and anaphylactic shock, as well as the full range of traumatic emergencies including open fracture, and falls from height. Duncan Higham, SSI Energy managing director, said it provided a significantly higher-grade service to that offered currently by technicians with first-aid training. It also allows the incident of false reporting to be cut significantly. “This can make significant cost-saving to operators as paramedics are far more capable of diagnosing correctly and have a significant protocol of drugs

Work recently got under way on the Institute’s latest construction project with digging a whole for the heavy-duty foundations of a 250 m2 hall in the direct vicinity of IWES´s nacelle test bench. If all goes to plan, a new test stand for minimal systems – comprising a high-speed generator and converter system – is set to open there in spring 2019. This test facility is being financed in the scope of the HilGridCop project funded by the German Federal Ministry for Economics Affairs and Energy (BMWi). The aim of its use is accelerated electrical certification testing of wind energy turbines at considerably lower costs than those associated with the testing of a complete nacelle. The new test stand and the DyNaLab will share a virtual grid, which will be expanded substantially so as to allow additional and more advanced functions. Construction projects so close to the port quay in Bremerhaven bring with them special requirements: in order to be able to lay resilient heavy-duty foundations with a 15 cm-thick steel plate in the sandy ground, there are 30 piles measuring 15 meters in length in place to secure the foundation plate. This results in a load-bearing capacity of 650 tonnes. The costs

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

Achieving the correct bolt pretension is essential in assuring bolted joint integrity. Bolted joints are critical when ensuring the safe operation of wind turbines or other similar bolted connections. In this context, ultrasonic measurement has proven to be a very accurate and cost-effective solution when installing new bolts, as well as when evaluating existing bolts as part of determining the lifespan of wind turbines. R&D explains why to PES. In recent years, wind energy has become an important source of electricity production. As with any other technology, wind turbines have a limit to their time in functional operation. Currently, wind turbines are designed to be efficient and reliable for 20 years, with the possibility of extending beyond that. Continuous inspection of wind turbines is important as it can maximise the turbines’ life expectancy as well as minimise the risk of failure. In this context, the importance of correct bolt pretension is frequently underestimated, as incorrect installation can increase the risk of partial or total failure in wind turbines, since these bolts hold critical components together in the turbine as well as the tower. A fully tightened bolted joint can sustain millions of load cycles without any problems, whereas a joint consisting of untightened
