The role foundations play in the deployment of larger, heavier, more powerful wind turbines, in deeper waters and further from shore, has perhaps not received the attention it deserves. But it is crucial in driving down offshore wind’s levelised cost of energy to the point where it can compete with fossil fuel and nuclear sources. Technology and costs compared Fixed foundations, whether monopile, jacket or gravity base designs, now support towers and turbines that weigh well over 1,000 tonnes and have a tip height of more than 200 metres. The foundations need to be able to do this, in high winds and heavy seas, for at least the 25 years of the turbine’s anticipated operating life. Monitoring the structural integrity of the foundations, especially in the critical areas of greatest strain – just above and below the seabed – requires high expertise and state of the art test and measurement technology. This is a field where industry development has outstripped design standards. There is no easy guide for offshore developers. In this report, technology leader HBM Test and Measurement compares resistive and fiber-optical gauge systems for offshore wind foundations. To help design verification, or as a system to provide long-term assurance that the foundations

As the wind industry continues to grow and mature, O&M models for the servicing of wind farms are becoming more diversified. With increasing competition and margins under pressure, it’s crucial to adopt an O&M model that is cost-efficient while securing high availability. Over the last decade, while the wind industry was still maturing, most development companies had a clear focus on portfolio growth. This resulted in a quick build-up of competencies around project development and construction, with less focus on O&M strategies. But as more owners in the industry became industrial – overseeing GWs rather than MWs of installed capacity – the need for more strategic asset management became apparent. Like other industry players with roots in the conventional energy sector, EC&R adopted the proven approach that has been applied to hydro, coal, gas and nuclear assets for over 100 years: performance optimization during operational lifetime, and lifetime extension to maximise returns on both past and future investments. Choosing the right O&M model Today, there are three main wind O&M service models available in the market: OEM services, Independent Service Provider services and self-perform/in-house O&M: Buying a wind turbine from a manufacturer typically comes with an OEM (full) service contract. Such a contract is

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

More and more with the growth of wind farms in the North Sea, depots in convenient locations that offer fast and efficient services are imperative to ensure continuous power generation in the face of an emergency or breakdown. PES wanted to find out more about Cargostore, who as the world’s largest operator of DNV 2.7-1 certified Reefer Cargo Carrying Units (CCUs), are providing such a service. Utilizing DHSS quay side yard space at Eemshaven, Cargostore Worldwide Trading Ltd’s dedicated CCU depot provides round the clock service to wind farm projects. Holding a full range of DNV 2.7-1 certified equipment, wind farm project managers can now access reefers, hazardous goods containers, rigging lofts, storage units, workshops and toolboxes, 365 days of the year, 24/7.

Over the years, Jo van Montfort, from Bjond b.v.b.a. has convinced PES that the wind industry needs to look beyond standards and protocols to reduce the maintenance costs of turbines. It seems incredible that companies don’t seem to realise that they are not getting the best out of their coatings, despite what the tests say. Definition The best definition of a protective coating system is: ‘Transparent or coloured product that forms a film and protects the surface on which it is applied against influences from the environment.’ This means a barrier is created between the steel and environment in order to prevent corrosion. This barrier is applied as a liquid material that adheres to the steel substrate and forms an oxygen, chemicals (‘salts’) and water or moisture proof film. In most cases, this film is less than 1mm thick and more than 300μm. In many cases this thin film needs to protect the steel for more than 20 years, preferably maintenance free. Type of failures The main failure of a coating system when properly applied is losing its main barrier function. This means the coating cracks. When the cracks grow through the coating oxygen, water and chemicals (‘salts’) can reach the steel substrate, resulting in
