Offshore wind is all the rage right now, competing without subsidies, floating into deeper waters with new foundation designs and bigger turbines. For all its promise, however, offshore wind remains mostly a European affair, with more than 15 gigawatts of capacity installed in European waters by the end of 2017 and less than two gigawatts elsewhere. Slowly but surely the picture is beginning to change. The US, and Asian countries including Taiwan, are progressing ambitious offshore wind plans. Leading European energy companies want to benefit from this ambitious mood. PES invited Vladimir Nicolaas, innogy Head of Offshore Growth & New Business, and Chris Willow, innogy Business Development Manager Offshore Wind, to give an insight into innogy’s global offshore growth aspirations. With more than 1,000 megawatt of installed capacity (pro rata), innogy is one of the world’s leading operators of offshore wind farms, trailblazing the industry since 2004. Together with investment partners, the company owns seven operational wind farms off the UK, German and Belgian coasts. ‘Our strong European footprint is the backbone for our global growth plans,’ Chris explained. ‘Our aim is to actively pursue and unlock opportunities worldwide,’ Vladimir added. ‘We plan to do this by entering into partnerships with

Lindø Industrial Park saves time and manpower by replacing heavy polyester slings with lightweight Dynamica SafeLift slings manufactured in Dyneema®. The industrial park on Funen has a great experience with the handling and shipping of large components for the offshore and heavy industry. The industrial zone in Odense is, amongst other things, a collection point and a storage depot for jackets for offshore wind turbine foundations. Jackets are 63m tall steel structures with a weight of up to 665t per piece. This figure corresponds to the weight of 27 fully loaded lorries! A gantry crane with a capacity of 1,000 t is used several times, both to gather the jackets and then to move them around for storage or shipping. The process involves lifting of so-called 3D structures, which have a height of 55m and a weight of approx. 500t per piece, where rigging needs to be done at a height of some 50 or 60m. A lifting sling is lowered down along the foot of a jacket, pulled underneath two stiffs, and then guided back up to the beam. Lindø Industrial Park has used polyester slings for this type of lifting until very recently. In this case a standard polyester sling had

Blaaholm designed and manufactured the Davit Crane because of the increased weight of future wind turbine components, which puts greater demands on crane capacity and the demand for savings on service costs from their customers. PES sat down with Torben Blaaholm to find out more about this crane’s innovative features. The new crane offers the following key features: a lifting capacity of 1000kg to 2000kg, automatic and manual overload protection systems and special features for easy access for the servicing. We also provide a special service through a partnership with Fanø Kran-Service, which provides great benefits for our customers. We developed the Davit Crane in cooperation with our customers in the wind industry, due to the increased weight on future components used in wind turbines, which places greater demands on the current onsite crane capacity. It’s is new to the market and the reduced service costs and competitive prices have secured early success. There are already signed contracts and we have been invited to tender on a significant number of offshore wind projects. Located in Esbjerg, Denmark, Blaaholm has developed and produced lifting equipment for the wind industry since 2008. We supply solutions worldwide within 4 business areas: tower production, wind industry, automation &

The offshore wind market is set to grow six-fold by 2030. A recent report states that the UK, Germany, The Netherlands, and China will drive forward the development of new fields over the next decade, while Taiwan and the US will become more prominent gigawatt markets. The latest wind farm to be developed in Europe is now under construction off Aberdeen’s coastline. The European Offshore Wind Deployment Centre (EOWDC) is Scotland’s largest offshore wind test and demonstration facility and is being developed by Vattenfall-owned Aberdeen Offshore Wind Farm Limited. It will comprise of eleven turbines and is expected to be operational in summer 2018. Such innovative developments, as well as the upkeep and maintenance of existing offshore wind farms, require the safe transfer of personnel and cargo between turbines or offshore substations and vessels. Ampelmann has been a pioneer of Walk to Work (W2W) gangway systems for more than a decade. The company is enhancing its motion-compensated gangway systems to create even greater operational efficiencies for offshore wind projects. Innovation in action Using technology inspired by the flight simulator industry, The Netherlands headquartered company boasts a wide range of gangway systems to compensate all six degrees of freedom of a vessel. This enables the transfer

It is well known that on large scale PV farms clean panels are essential in order to produce peak yields. The Italian company Messersì has been offering PV cleaning solutions for 7 years. Their product, Roboklin 25, is a fully automated machine and it delivers efficient cleaning to large PV farm operators. The company’s main business is actually building special vehicles for construction and agriculture, the Roboklin 25 was developed as a solution for cleaning solar modules. 40 units have been sold worldwide so far. During 7 years, working in many different conditions around the world Messersì acquired a lot PV cleaning experience. The tracked vehicle is powered by a turbocharged diesel engine from Kubota and has a maximum cleaning capacity of 1MW in five hours. The telescopic arms have maximum lengths of 4 and 6.5m. Two washing systems can be mounted on them. There is either a sprinkler system with a maximum pressure of 40bar or a rotating brush: 3 sizes of 2.2, 3.6 and 4.2m long. Both systems are supplied from a tank with a capacity of 2400l. Cleaning is controlled through ultrasound sensors, which ensure that the distance between the modules and the cleaning system is always the same, automatically

In this day and age when downtime prevention, maintenance and cost reductions are key, remote surveillance must be one of the top ways to improve all three. PES went to find out the latest developments from Moventas who have remote surveillance centres in Finland, Italy, UK and the US to monitor over 2,500 wind turbines globally. The Moventas Condition Management System (CMaS) gathers critical data on turbines in operation, which is analysed by a team of experts to help ward off unexpected failures. CMaS operates on all gearbox types. Thus Moventas provides surveillance for turbines deploying a range of different gearbox brands. A broader view of the whole drivetrain with CMaS and its intelligent sensors CMaS was developed to monitor how the gearbox and other drivetrain components in a wind turbine perform. It anticipates possible upcoming failures and it guarantees the continuity of their energy yield. Traditional condition monitoring products focused mainly on measuring vibrations from rotating components. CMaS, on the other hand, is based on a profound understanding of the various failure modes of the drivetrain as whole. For example, it is possible for early changes in oil lubrication properties to be visible, long before they can be measured in vibration. CMaS technologies

In 2002 the first ever offshore high voltage substation was delivered by HSM Offshore. This was under an EPCI contract from Eltra/Energinet, for the Horns Rev A project, off the Danish West coast. Things have gone from strength to strength since then, as this report to PES shows. Earlier this year the company signed the EPCI contracts for the TenneT TSO B.V. Borssele Alpha and Beta Substations. It really is remarkable to see the growth in transformer capacity lead to larger topsides and substructures. Lately we have also seen further increases in inter array and export voltages, as well as significant growth in the supply scope for EPCI contracts. The Horns Rev A Substation featured a transformer capacity of 160 MW and topside weight of 1,100 mt and was placed on a multiple pile foundation. The Asian Hercules II floating sheerlegs and the IB 909 jack-up were used for the installation. In 2007 there was another EPCI contract for the same customer, for a 250 MW Substation, featuring 1,300 mt topside and this time, with a jacket weighing 1,000 mt, the installation of both were undertaken by the Matador 3 floating sheerlegs. The 325 MW Thornton Bank Substation was HSM’s first Substation project in
