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

Jan De Nul Group was contracted by Ørsted to transport and install 36 monopile foundations and the scour protection works around all 56 foundations for the Borkum Riffgrund 2 offshore wind farm. The cable installation works connecting the OWF to the offshore substation were also executed by Jan De Nul on behalf of TenneT. Thus, proving the efficiency of a bolted connection between MP and TP. Germany continues to invest in green energy. By early 2019 approximately 460,000 additional households will be provided with sustainable wind-generated electricity by the Borkum Riffgrund 2 Offshore Wind Farm. Borkum Riffgrund 2 counts 56 Vestas turbines of 8MW each, resulting in a total capacity of 450 MW. Twenty turbines were installed on 50-metre-high jackets with 10-metre-high suction buckets. Thirty-six other turbines were placed on top of monopile foundations. In the summer of 2016, the owner and developer Ørsted Wind Power A/S awarded the contract for the installation of the monopile foundations to the Jan De Nul Group. The scope comprised the temporary storage, transport and installation of 36 monopile foundations (MPs), 36 Transition Pieces (TPs) bolted on top of the MPs, and the anode cages. The Jan De Nul Group was also responsible for the supply,

Some years ago, the offshore wind industry was primarily a high-priced and tough European adventure. But, mainly as a consequence of intense private-public collaborations in the key countries nearby Irish, North and Baltic seas, this situation has dramatically changed. Nowadays, the offshore industry is widely recognized as a key component for the future generation mix, proudly showing a flourishing market with a new range of turbines, well-built supply chain and continuously optimized costs. As a result of this recent market progress, other countries beyond Europe have focused on offshore solutions too, arranging plans for gross spread of this industry mainly in North America and Asia. As an example, more than 1GW of offshore was installed in China during 2017 and determined programs for offshore expansion, have recently been set in the US for the next decade. The Indian government has recognized that both the demand for electricity and the need to decarbonize is going to rise steadily and so has defined forceful objectives for 2022. Thus, offshore wind is set to become a relevant sector in the medium and longer-term plans. The areas of Gujarat and Tamil Nadu have already been identified, as places where strong and steady resources of clean energy, can be
