In Europe today, it is standard to equip newly built wind turbines with service lifts. These allow technicians easy access to all levels of the tower. Many older turbines do not have this advantage and require operations and maintenance personnel to ladder climb instead. On such wind farms, there are countless soft tissue injuries due to the repetitive motion of climbing. These injuries lead to sick days, reduced motivation and can stress the operation efficiency of the project. 3S Lift offers specialized retrofit solutions for existing turbines that allow technicians to ascend towers more quickly and protect their health against the strain put on the body by climbing. This way, they can reach the top rested and start their work right away. Over the last 20 years, 3S Lift has become a leading global wind turbine tower internals (WTTI) solution provider. With locations in China, India, Europe and the US, the company supplies a wide range of products to wind turbine manufacturers, tower manufacturers, service providers and wind farm owners across more than 40 countries. Retrofitting existing wind turbines with these solutions can add considerable value, improving both, health & safety and economic performance. That’s why a number of large developers are

With two new vessels a Danish shipping company has broken records within both safe, reliable and cost-efficient crew transfers in the offshore wind industry. But this is not all… PES is delighted to bring you a preview of MHO-Co’s ‘green’ hybrid vessels of the future, which are in the pipeline at this very moment. The two sister vessels ‘MHO Gurli’ and ‘MHO Esbjerg’ were designed by the CEO of MHO-Co Mik Henriksen, who founded the shipping company in 2015. He has a long career in the industry, having built both aluminium ferries and crew transfer vessels, and with he has never concealed his ambitions to challenge and push boundaries within safe and reliable crew transfer, whilst minimizing both the financial and environmental costs of sailing to and from offshore wind farms. Measuring 39m, holding up to 65 tons of cargo and with enough room for 24 technicians, these sister vessels are the largest offshore wind farm taxis in the world. And indeed, ‘Gurli’ and ‘Esbjerg’ were met by scepticism from the industry, when they were set afloat in January and May 2019, respectively. A scepticism which has long been put to rest. ‘Of course, there were teething problems with a completely redesigned

The global offshore wind industry is developing the next generation of offshore wind turbines. These turbines can be more than 270 metres high and are fitted with blades of 120 metres long. Offshore installation vessels currently available on the market are facing increasing difficulties to install these types of turbines due to the turbines’ sizes and installation heights, as well as the ever-increasing foundation dimensions. PES brings you the latest update from the Jan De Nul Group. Based on the above findings the Jan De Nul Group decided to design and order the Voltaire earlier this year. The Voltaire is a revolutionary offshore jack-up installation vessel, named after the French writer, historian and philosopher François-Marie Arouet, known by his pseudonym Voltaire and as an icon of the European Enlightenment of the 18th century. Both Voltaire and our jack-up vessel are pioneers within their field of expertise. This is the third vessel of its kind in the Jan De Nul fleet, after the Vole au vent and the Taillevent. With an unrivalled crane capacity of over 3,000 tonnes, this jack-up vessel will be able to support the renewable energy industry to build the future wind farms at sea. ‘Upon her delivery in 2022,

The Port of Thyboron is a one-of-a-kind industrial port on the Danish coast. Given its unique position, the port is developing with rising cargo transportation, lucrative maritime and fishery sidelines and has the potential to increase together with the rise in the offshore wind farm activity in the North Sea as wind farm site and hub. Thyboron Port is an independent port, owned by Lemvig Municipality. Located on the Danish North Sea coast inside the Limfjord, it has 5.5km of quay line at water depths varying from 3.5m to 9m. ‘Yes, we are very busy,’ reflected Port Director Jesper Holt Jensen. ‘But the unique atmosphere around the port, the companies that support each other and the projects we are embarking on, just adds to the one-off can-do attitude that you will rarely find elsewhere across Europe’s ports. ‘We might be small in stature, as the tenth biggest cargo port in Denmark, but we are big on getting the job done. Unstinting cooperation between all companies within the port is renowned. It is the port’s DNA.’ Indeed, the word ‘unique’ crops up many times when talking about the activities, the positioning and the overall performance of the Port of Thyboron. Founded by

Solaxess SA is a Swiss company specializing in the design of materials for the photovoltaic (PV) industry, intended for the realization of architectural projects. Thanks to technology developed by CSEM, and three years of reliability and certification, Solaxess contributes significantly to the aesthetic improvement of photovoltaic panels. Now, they are an integral part of buildings, whether on facades, terraces or roofs. The company is active in distributing its products to PV panel manufacturers around the world. Our films, 0.1 to 0.5 mm thick, are integrated onto standard PV modules during their manufacturing process. This means it’s possible to obtain a white, grey or other light-coloured PV panel that is completely uniform. The main innovation is the capacity to maintain optimal performance, with excellent aesthetics. This specificity is essential for the development of so-called ‘active’ facades in the field of BIPV (Building Integrated Photovoltaics). Our films allow builders, developers, and architects to treat PV panels as a new building element in their own right. These new photovoltaic panels are totally invisible, even from close up. They could be mistaken for aluminum, Eternit or lacquered metal panels. Solaxess has now moved in to new premises specially adapted to its development.

Solar photovoltaic systems, once an emerging technology, are rapidly moving towards becoming a mainstream source of electricity throughout the world. However, less than a decade ago the solar industry was undergoing a difficult period of transition, with the price of PV panels decreasing globally, driven partly by an increase in competition from China. Many solar companies were struggling to survive. It was around this time, that five friends decided to enter the market: Guy Sella, Lior Handelsman, Yoav Galin, Meir Adest and Amir Fishelov. With backgrounds in electrical engineering and research and development, the five friends recognized that there were technical difficulties holding the industry back. While less recognizable than the solar panels, the inverter is one of the most important components within a PV system as it acts as the brain of the PV system. Inverters convert the direct current (DC) electricity generated by the solar panels into the alternating current (AC) used by the grid and in our buildings. They also manage the power output from each of the panels within a solar system. However, each of the panels within a system typically performs at a different level from the others. As a result, an overall maximum output for each
