The offshore wind installation industry, is faced with the challenge of investing in next generation installation equipment, for the installation of wind turbines that are still on the drawing board. This brings a lot of uncertainties. What we know for sure is that in the past the growth rate of turbine size and weight consistently outpaced the predictions. As a consequence, the main challenge is striking the right balance: invest in a jack-up that can do all; you may be too expensive in the first few years to be competitive. Or, invest little and start off with a smaller jack-up; you may be out of business soon for not being able to handle the increasing size and weight of the future wind turbines. GustoMSC has a strong position in the renewable business, and in particular in the design of offshore wind installation jack-ups and delivery of the key equipment to those vessels, such as the jacking system and main crane. GustoMSC explains how only with proper balancing of requirements and smart innovations, the outward spiral of increasing size, weight, carbon footprint and cost can be mitigated. GustoMSC’s role is to provide its clients with well-balanced solutions, which must include robustness to

According to the World Economic Forum, the Internet of Things (IoT) which focuses on the extension of internet connectivity to everyday physical devices will be the driver of the fourth industrial revolution1. The Internet of Things represents a new reality, the data collected from internet devices can be used to enhance efficiency, develop new services, fine-tune decision making, solve intricate issues and create innovative solutions. For the energy market, the IoT has brought a new insight, by including new capabilities to support a wide range of vertical markets, from industrial controls to data centres alike. Furthermore, this translates to greater flexibility to accommodate more energy resources, better management of assets and operations, further improvement in reliability, as well as security and better customer service. Introduction IoT has the potential of solving the main problems associated with renewable energy such as intermittency, variability, energy wastage and storage. IoT enables objects, which are part of a larger distributed system to communicate effectively over the internet. Hence, renewable energy sources in different locations can interact through an energy cloud, to feed information to the electric grid, when there is an excess or shortfall in energy supply or demand. Examples of these applications include the Tesla Power

Abstract: The continuing increase in rotor diameters is pushing the structural load-carrying capabilities of turbine blades to the limit. In order to ensure reliability and structural integrity, representative testing and validation methods are now more important than ever before. Development in wind turbine blades Wind turbine manufacturers are continuing to increase rotor diameters with the aim of boosting annual energy production (AEP). Due to the high installation costs per turbine, this is especially true for offshore blades, but onshore turbines are also increasing in size, as multi-megawatt turbines are being developed for lower wind speeds. Direct scaling of blade dimensions would result in a cubic relationship between blade mass and blade length. However, this is certainly too conservative for some areas of the blade, for example the skin panels, which need to scale with the blade surface area. Thus, a theoretical scaling exponent below three is expected. In the past, this ‘square-cube law’ has repeatedly been beaten due to both design and material innovations, and scaling factors between 2.2 and 2.4 have been reported. This illustrates how structural load carrying capabilities are pushed to the limits. Put simply, mechanical loads on wind turbine blades can be categorized into flapwise loads, which

Andrew Wickham, Managing Director at Buoyant works, has been involved in impact protection design, engineering and manufacture for the past 25 years. Developing and creating brands such as Hippo Marine and Manuplas, both long standing manufacturers of fendering, booms, buoys and other impact absorbing structures, has pioneered a new design. WindShield is a long-term protection system for the boat landing piles on offshore wind turbines, using established seaworthy materials that will work with the bow fender systems of the Crew Transfer Vessels (CTV). Coating failures on the landing piles of offshore wind turbines are beginning to cost O&M firms increasing sums of money to maintain and repaint. These are critical structures used to facilitate the safe transfer of maintenance crews onto the turbines. The failure of a coating can result in corrosion of the steel structure, accelerating wear and reducing its lifespan. Crew transfers may become compromised, potentially unsafe and could lead to further damage of the turbine and the crew vessel. The three participants in the crew transfer process are the crew, the turbine and the pilot vessel. All of them need to work together to create the safest possible environment. Operations need to be efficient and effective to

Offshore wind structures are exposed to an extremely corrosive environment. As a result, corrosion rates of steel are high, >0.5 mm/year, and coating systems must perform extremely well. Jo van Montfort from Bjond, gives PES his professional viewpoint on some of the pitfalls of the current certification processes and outcomes. This means all stakeholders involved need to increase their level of knowledge in this area. The most important requirement for a coating system for an offshore wind structure in the leading directive, DNVGL-RP-0416, is as follows: ‘Sufficient attention must be paid to the design life of the structure and the economic aspects of repairing the coating if necessary (and realistic).’ In our opinion this means 25 years maintenance free, because repairing/maintaining a coating system under offshore conditions is undesirable, almost impossible and very expensive (x1000 versus a paintjob onshore). Therefore, the durability ranges in the latest leading coating standard EN ISO 12944 have been revised. Now a very high (VH) durability range has been included, which means the first maintenance work should not be necessary for 25 years. In the former version and until now this was for 15 years. The question is how to achieve that? Current situation In the offshore wind industry,
