Offshore wind turbines are the giants of wind power and their construction is an impressive spectacle. Extremely heavy, massive components are moved on the water by even more powerful equipment. Over the past decade, the German company Schmidbauer GmbH & Co. KG has established itself as a logistics partner for the offshore industry. This company has not only continuously expanded its fleet of crane vehicles to meet the needs of the industry, but also invested in the service know-how of its personnel. New 6-axle Scheuerle SPMTs were purchased last year alone. So the crane and heavy-load expert is therefore in action at numerous European feeder ports and ports involved in the construction of offshore wind farms. Heavy load logistics for the Merkur offshore wind farm One of the current projects: the transhipment of transition pieces (TPs) for the Merkur offshore wind farm, at the Orange Blue Terminal in the Dutch port of Eemshaven. 66 ‘Haliade 150’ GE-type wind turbines, which should achieve a standard capacity of approx. 1750Gwh per year, are currently being constructed in the North Sea, about 45 kilometres north of the island of Borkum. The work for the construction of this wind farm started at the beginning of 2017 and it is expected

Readunit is a new, flexible, tool management software system, designed with the wind industry in mind. This is a time saver for companies and once set up, all stock movement, mandatory testing becomes automatic and with the option of RFID, via the telephone or tablet APP. PES had a lot of questions for Torben Kofoed the owner. PES: Hi Torben, welcome to PES Wind magazine. Thanks for talking with us. Would you like to begin by explaining a little about the background of Readunit and the importance of the wind industry to you? Torben Kofoed: We are a software company, founded because we saw the need for a good system to keep track on regulatory inspections and documentation. We want to help companies move from manual work in excel, or access-based systems, to a real software designed exactly to meet the needs in the wind industry. From the start Readunit was based on the idea of creating an easy to use software that can and will be used in day to day work, not just another software, never to be used. It is a tool for the users, who want to make their daily work easier. At the same time the company as

Carsten Aa, chief executive officer of LINDØ port of ODENSE in Denmark, talks to PES about his vision for the site, and its expansion into a specialist cluster supporting the offshore wind industry. PES: Welcome to PES Wind magazine, it’s great to talk with you. We would like you to begin by explaining a little about the background of LINDØ port of ODENSE and the importance of the offshore wind industry to you? Carsten Aa: The port is owned by the local municipality. At the beginning of 2014 we bought the former shipyard, which had been owned by A.P. Moller-Maersk Group, and began to transform it from a shipyard into a port area specialising in heavy load, and in particular supporting the area’s offshore wind cluster. We merged the two former companies, the old port and shipyard, into one new company, which we called LINDØ port of ODENSE (LPO). The port specialises in supporting the wind industry, and has nearly 200,000 square metres of production halls and storage buildings, and some of the largest cranes in Europe. We have now re-built and renewed most of the area, and are close to completing its transformation into the most modern port area in Europe for the

When you look ahead are you able to say with confidence that your business, organization, or community is truly prepared for a radically different future of energy? It’s the time of year when demand on the world’s energy systems peak. Summer in many parts of the world means that electrical grids are working overtime to power the cooling and ventilation systems that keep large cities safe from sweltering urban heat. And yet, in other less developed parts of the planet, temperatures will reach deadly levels from which there is no escape, and people will die. Our survival is totally dependent on our ability to continue to power the world we live in. But because energy is a limited resource, it’s not equally distributed. Most views of the ‘almost probable certain future’ show this situation being addressed slowly over the next five decades – and way too late for many who will perish for lack of a reliable energy supply. But what if we could embrace a fundamental shift in thinking, reset our priorities and investment plans, and set ourselves on a very different path to the future? In The Future Reinvented – Reimagining Life, Society, and Business we look a wide range

Years of experience and a large fleet of vessels mean that Northern Offshore Services are well placed, as leading operators in crew transport vessels (CTV) primarily in the offshore wind industry. David Kristensson, the CEO, got together with PES to catch us up on the latest developments and give us his outlook on the future. PES: Welcome back to PES Wind magazine. Thanks for talking with us. For the benefit of our new readers would you like to begin by explaining a little about the background and experience of Northern Offshore Services and the importance of the wind industry to you? David Kristensson: The background and the experience of Northern Offshore Services (N-O-S) is that we have roots in the shipping industry and come from a maritime culture. We have been working with shipping and vessels for generations and ten years ago we started a new company that has become Northern Offshore Services. In this company our focus is the niche market in specialised shipping. Our biggest business is crew transfer vessels for offshore wind, so the wind industry, is of course, very important to us. Today, as one of the leading operators in this sector we operate approximately 40 vessels. PES: Has there

When CEO Mik Henriksen founded MHO-Co in 2015, he could not have known that in only three years, his vision of designing vessels of the best reliability and safety in the industry, and at a low cost, would be a reality. Today, boasting five vessels, having already reached the 2020 target, MHO-Co covers the demand for transportation between shore and wind farm in the ‘greenest’ and economically viable way. PES discovered the strategies necessary to fulfil the dream. With roots in working with aluminium ferries dating back to 1993, Mik Henriksen has dealt with all operational aspects since, maintenance, operation and commercially, and has been involved in designing and building fast ferries and CTVs. Previously COO for KEM-Offshore ApS (Esbjerg), a role in which he thrived and converted a 13-manned business to one of 70, Mr Henriksen has gained qualifications in both MBA (2013) and CBA (2015), which inspired him to create MHO-Co in October 2015. The goal was to primarily provide services to the wind farm industry, transporting personnel and equipment back and forth to offshore wind farms with the best reliability and safety in the industry, and low cost. With the expert team at MHO-Co sharing its knowledge of equipment,

Since 2016 MegaWindForce has been working on a special type of wind turbine with remarkable characteristics. The team found a way of improving electricity production by leaving off 1/3 of the blade! Innovative carbon production methods make this attainable. A worldwide patent was granted on this invention. With the growth of the size of turbine rotors, the driving torque at the blade root section increases more than linearly, with the length of the blade. In the case where the same materials and concept are being used, the weight increases cubically with size, demanding heavier structures to withstand forces. The low rotational speed meant the hub needed to be bigger, for the direct drive generators and heavy gearboxes. By replacing the main shaft with a ring-shaped generator-support combination, the disadvantages of classical up scaling are eliminated. The Concept The rotor area, close to the rotor centre, contributes only a small part to the energy production of a ‘classical’ wind turbine. This area plays a crucial role in supporting the blades and absorbing the driving forces of the generator system. In the MWF concept, forces are spread equally over the large surface of the ring, avoiding stress concentrations. Since the ring is sized 1/3 of

Data can be our crystal ball. With advanced analytical tools, we can harness the flow of data from turbines, solar cells, dams, our organisations and even external sources, such as energy markets, to optimize performance and earnings. You can look into the future, now. Businesses thrive on predictability. Stable demand, stable supply, stable operations and, if we’re doing it right, stable growth and positive development that leaves us, and all our stakeholders, with stable smiles on our faces. However, renewables are unpredictable. The supply of energy we convert is inherently unstable – it fluctuates according to the whims and fancies of a power beyond our control, that of Mother Nature. Hydropower is perhaps the exception, as dams offer operators a steady means of power storage and production. All we have to do is, quite literally, turn on the tap. Nevertheless, unpredictable weather patterns, such as prolonged dry periods, can impact upon even this most proven and reliable of renewable sources. So, how do we bring predictability into this new energy arena? We can’t tame Mother Nature, but we can learn from her, from ourselves, from our equipment, and from the energy market to continually adapt and optimize our assets and operations. In doing
