The present invention provides a foundation for a wind turbine. To reduce set-up time and to allow complete alignment of the platform which carries the base flange of the tower construction, the invention provides a foundation with a cage structure having an upper stress distribution flange connected by a plurality of tensioned anchor bolts to a lower flange. The flanges are separated by a number of distance elements whereby the shape of the cage structure becomes fixed by the combination between tensioned bolts and distance elements. Since the cage structure has a fixed shape, the upper stress distribution flange can be aligned before the cage structure is embedded in concrete, and it becomes unnecessary to wait for the concrete to harden.

In order to unlock the full potential of Europes offshore resources, network infrastructure is urgently required, linking off-shore wind parks and on-shore grids in different countries. HVDC technology is envisaged but the deployment of meshed HVDC offshore grids is currently hindered by the high cost of converter technology, lack of experience with protection systems and fault clearance components and immature international regulations and financial instruments. PROMOTioN will overcome these barriers by development and demonstration of three key technologies, a regulatory and financial framework and an offshore grid deployment plan for 2020 and beyond. A first key technology is presented by Diode Rectifier offshore converter. This concept is ground breaking as it challenges the need for complex, bulky and expensive converters, reducing significantly investment and maintenance cost and increasing availability. A fully rated compact diode rectifier converter will be connected to an existing wind farm. The second key technology is an HVDC grid protection system which will be developed and demonstrated utilising multi-vendor methods within the full scale Multi-Terminal Test Environment. The multi-vendor approach will allow DC grid protection to become a plug-and-play solution. The third technology pathway will first time demonstrate performance of existing HVDC circuit breaker prototypes to provide confidence and demonstrate technology readiness of this crucial network component. The additional pathway will develop the international regulatory and financial framework, essential for funding, deployment and operation of meshed offshore HVDC grids. With 35 partners PROMOTioN is ambitious in its scope and advances crucial HVDC grid technologies from medium to high TRL. Consortium includes all major HVDC and wind turbine manufacturers, TSOs linked to the North Sea, offshore wind developers, leading academia and consulting companies.

The overall concept of MANTIS is to provide a proactive maintenance service platform architecture based on Cyber Physical Systems that allows to estimate future performance, to predict and prevent imminent failures and to schedule proactive maintenance. Maintenance is no longer a necessary evil that costs what it costs, but an important function that creates additional value in the business process as well as new business models with a stronger service orientation. Physical systems (e.g. industrial machines, vehicles, renewable energy assets) and the environment they operate in, are monitored continuously by a broad and diverse range of intelligent sensors, resulting in massive amounts of data that characterise the usage history, operational condition, location, movement and other physical properties of those systems. These systems form part of a larger network of heterogeneous and collaborative systems (e.g. vehicle fleets or photovoltaic and windmill parks) connected via robust communication mechanisms able to operate in challenging environments. MANTIS consists of distributed processing chains that efficiently transform raw data into knowledge while minimising the need for bandwidth. Sophisticated distributed sensing and decision making functions are performed at different levels in a collaborative way, ranging from local nodes to locally optimise performance, bandwidth and maintenance; to cloud-based platforms that integrate information from diverse systems and execute distributed processing and analytics algorithms for global decision making. The research addressed in MANTIS will contribute to companies assets availability, competitiveness, growth and sustainability. Use cases will be the testing ground for the innovative functionalities of the proactive maintenance service platform architecture and for its future exploitation in the industrial world. Results of MANTIS can be utilised directly in several industry areas and different fields of maintenanance.

The LASIMM project aim is to develop a large scale flexible hybrid additive/subtractive machine based on a modular architecture which is easily scalable. The machine will feature capabilities for additive manufacture, machining, cold-work, metrology and inspection that will provide the optimum solution for the hybrid manufacturing of large engineering parts of high integrity, with cost benefits of more than 50% compared to conventional machining processes. For large scale engineering structures material needs to be deposited at a relatively high rate with exceptional properties and excellent integrity. To ensure this the machine is based on wire \ arc additive manufacture for the additive process. A unique feature of the machine will be the capability for parallel manufacturing featuring either multiple deposition heads or concurrent addition and subtraction processes. To facilitate parallel manufacturing the machine architecture is based on robotics. To ensure that the surface finish and accuracy needed for engineering components is obtained for the subtractive step a parallel kinematic motion robot is employed. This robot is also used for application of cold work by rolling between passes. This ensures that material properties can be better than those of forged material. A key part of this project is the development of ICT infrastructure and toolboxes needed to programme and run the machine. The implementation of parallel manufacturing is extremely challenging from a software perspective and this will be a major activity within the project. To deliver this extremely demanding and ambitious project a well-balanced expert team has been brought together. There are ten partners comprising six companies, two Universities and two research institutes. Two of the companies are SMEs and there are three end users from the renewable energy, construction and aerospace sectors. The consortium also features the whole of the supply chain needed to produce such a machine.

RAMPup aims to improve European SME production competitiveness by effectively decreasing the integration effort needed for automating small production lines. A framework and infrastructure for modular industrial automation systems will be developed and applied to eight use-cases from four European end users, carefully selected to require a broad range of processes. Technologies for automating these processes exist, but are too inflexible and expensive for the business case for automation to be viable, certainly in SME contexts. Four demonstrators will be realized and brought to TRL7 proving their performance in real operational environments at end user sites. The methodology involves creating manufacturer-independent process modules which are self-contained: hardware, software and process functionality; wrapped to be plug-n-play with all other modules in the set and with the framework platform. We anticipate that many modules will be based on existing technologies, completed and wrapped to become RAMPup modules. A repository of process modules at this level, accepted as usable by SIs, will greatly reduce the customization needed for new automation installations, thus reducing the cost to end-users. Modularisation also allows physical reconfiguration of the workcell and re-use of component modules across very different product variants. Beyond the technical realization of the modular automation framework, RAMPup aims to open a new market allowing developers of automation solutions to deploy, distribute and commercialize their products. RAMPup will demonstrate the business perspectives within the project and thus convince module developers and system integrators to enter the new market. The ambition in RAMPup is thus not only to create eight functioning robot workcells at end-user sites but also to provide a fast-track for SME robot developers to get their technologies to market.
