Long standing heavy lift specialist company BigLift Shipping, member of the Netherlands-based Spliethoff Group, is more and more engaged with developments in the renewable energy markets in Europe, and also in the US and Asia. Where wind turbines used to be relatively small, new generation turbine parts, particularly monopiles, are now so heavy and large that a state-of-the art heavy lift vessel is required for their transportation. BigLift has a track record when it comes to the transportation of wind-turbine related cargo, such as monopiles, transition pieces, jackets, nacelles, and wind blades. The new generation wind turbine is increasing in size and weight and brings with it a growing need for heavy lift vessels to transport the, also, growing turbine-pieces. BigLift’s Happy S-types and MC-Class Heavy transport vessels – the latter added to the BigLift fleet in January – are eminently suitable for such cargoes. Nacelles and tower sections for Merkur wind farm Starting in 2017, BigLift has made eight voyages for the construction-ready Merkur wind farm, located approximately 45 km north of the island of Borkum, Germany, in the North Sea. The wind farm will consist of 66 wind turbines and once complete will generate approximately 1,750 GWh annually, enough clean energy to

The renewable energy market is undoubtedly on the rise, particularly in Europe, where wind power is now the second largest source of electricity behind gas-fired power plants. According to a recent report from Wind Europe, the number of onshore and offshore wind turbines added a record 15.6GW of new energy capacity last year and the industry group also reported that 2017 was a record year for investment in future wind farms with agreements to build another 11.5GW of new capacity, worth around £19.8bn. While the number of renewable energy projects continues to grow, countries early to the renewable revolution such as Germany have older, aging fields that now require integrated inspection and repair programmes to maximise productivity. There is now a greater need for specialists in this field to provide the skills and experience to not only support installation of high quality wind farms, but also to maintain them throughout the full lifecycle. Enhanced lifecycle management Sparrows Group is a global provider of expert equipment and integrated engineering services to the energy and industrial industries. Last year the company acquired Alpha Offshore Service A/S in a deal that significantly strengthened the group’s operations and maintenance capabilities in the wind energy sector. There was a

In Europe alone, tens of thousands of wind turbines produce energy for countless households. Turbine maintenance or servicing is fundamental to ensure it stays this way. Because employees regularly work at great heights they cannot manage without fall protection systems - for example, when climbing a tower by means of a fall arrest system. PES went to find out about how SKYLOTEC ensure the safety of their employees and the training they offer both in house and globally. Leading manufacturers of fall protection equipment, such as SKYLOTEC, develop solutions for working at heights on wind turbines, with cleverly designed details, which enable simplified application and reduce the risk of an accident. Nevertheless, even if the equipment is intuitive to operate, regular training courses for rescuing colleagues involved in an accident are vital. In Europe, whenever maintenance or servicing work is due to be carried out on the wind turbines, fall protection for employees is mandatory. This does not just apply to once they have already reached the nacelle or the high external areas. In many cases, employees belonging to the maintenance firms or the operator can only reach these work areas by means of a fall arrest system, such as a

24SEA has been involved in various projects over the last years all focussing on foundation monitoring. Typically, up to 10% of the foundations within offshore wind farms are equipped with a Foundation Structural Health Monitoring (FSHM) system, consisting mainly of installing accelerometers and strain gauges in the transition piece. In the recent projects, for both the Belgian wind farm Nobelwind and the UK wind farm Galloper, 24SEA teamed up with TUBS and Com&Sens, to equip monopiles with optical strain gauges over the entire length of the monopile. With this innovative set-up, the projects aim to better understand the subsoil dynamics and to validate new design methodologies for the soil structure interaction. In addition, the subsoil sensors can be used to access the lifetime directly near the critical welds and validate the concept of virtual sensing below the mudline, where strains over the entire substructure are predicted using accelerometers only. In this piece, we will discuss the first results obtained from the optical strain gauges installed on the monopile. Motivation Offshore wind turbines (OWTs) are some of the most dynamic civil structures. The substructures of OWTs are loaded by both wind and waves, and agitated by the rotations of the wind turbine on

Global wind capacity is set to double by 2027, and the United States is in the midst of the most lucrative time to increase production of wind energy. Renewable companies are fueled by an urgency to capture tax subsidies and currently in many parts of the country; wind is the cheapest source of new electric generating capacity. Even with the many environmental benefits of wind farms over traditional sources, wind still faces opposition across the U.S., especially in rural areas. South Dakota has been expecting dramatic growth in wind energy production for some time now, but the contentious debates surrounding the approval of new wind farms has created a drift between residents and caused the state to lag. Although in most cases wind turbines will create a minimal impact on the landscape, some residents feel the turbines are too unsightly, loud, and disruptive to wildlife, ignoring the many benefits, such as tax revenue, the project will bring to the state and local communities. Despite the local opposition, there has been recent good news from the federal government for offshore wind projects, as the Trump administration announced it is pushing ahead with building wind turbines off the Atlantic coastline.

Wind power technology is advancing at a fast pace. The demand for full scale test systems is on the rise. All investors and manufacturers in the wind power industry want to make sure that turbines function flawlessly. A malfunctioning turbine is a nightmare, especially on offshore wind farms. PES brings you the latest from the new Peikko and R&D Test Systems partnership, which combines expertise and know-how, giving added value to the customer. ‘Repairing a turbine in offshore conditions is both difficult and costly. That is why the turbines are put through a series of vigorous tests in a controlled environment,’ says Lasse M. Stephansen, Senior Project Manager at R&D Test Systems. R&D Test Systems is an international engineering company with a strong track record within turnkey test bench solutions for manufacturers and test facilities. End-Of-Line Test is a procedure which every single turbine has to pass. However, it is the Highly Accelerated Life-cycle Test that makes the engineers’ pulses quicken. ‘During HALT, the machinery is subjected to strain equivalent to an entire 25-year life cycle. This puts the equipment under an enormous amount of stress and loads the test bench more than you can imagine,’ Lasse M. Stephansen explains. Foundation first With the increase
