Project Name: Deutsche Bucht Demonstrator

Acronym: DBOD

Coordinator: Universal Foundation A/S (DK)

Partners: Harland & Wolff Heavy Industries Ltd(UK), SIF Group BV (NL)


Universal Foundation and partners will demonstrate new technologies for offshore foundations. The offshore foundation to be demonstrated is the Mono Bucket; next generation novel foundation concept for offshore wind farms. The project will conduct full scale designs and installations of the Mono Bucket with WTG, including demonstration of the innovative Mono Bucket Design Configurator -and Integrated Design Model prepared by Universal Foundation, bringing the Mono Bucket ready for commercialization by advancing TRL for the Mono Bucket from TRL5 to TRL7.

The project addresses in particular the industry target of cost reductions up to 40% by 2020 and the need for new technology to move to deeper water (25- 55 meters), further from shore (+150km) and with bigger turbines (+6MW class), aiming to demonstrate a significant delivery of CAPEX reduction for foundations and a correspondingly significant impact on Levelized Cost of Energy (LCoE).

The project further seeks to demonstrate the Mono Bucket’s unique ability to install a foundation and a turbine in the same installation run and hence have the possibility to generate first power within weeks instead of today’s industry standard of ½-1½ years.

Finally, the project will demonstrate new products and solutions aimed at cutting O&M costs in relation to corrosion and scour protection.

DEMOWIND funded projects

Project Name: Compact High Efficiency Generator

Acronym: CHEG

Coordinator: Magnomatics (UK)

Partners: ORE Catapult Development Services Ltd (UK), GL Garrad Hassan Nederland (NL), Newton Derby (UK), EDF Energy R&D UK Centre Ltd (UK), JL Mag (NL)


As the market for large offshore wind turbines increases, the requirement to reduce the cost of energy becomes more important. The installed base of offshore wind turbines is expected to rise by up to 5 gigawatts per year through 2020.

This project aims to advance the state of the art in wind turbine generator technology by reducing the cost of the turbine and increasing the efficiency of the generator to reduce cost of energy. The generator and gear box are major turbine components and constitute a major part of the cost, complexity and failure modes of wind turbines. The use of the innovative pseudo direct drive (PDD) generator within wind turbines will reduce the capital cost of such installations and subsequent decommissioning and have a positive impact on operation and maintenance costs.

The Compact, High Efficiency Generator (CHEG) project will deliver a pseudo direct drive (PDD) machine based around Magnomatics innovative magnetic gear technology which brings significant advantages in efficiency and reduced costs of maintenance due to its method of transmitting torque through the magnetic gear without the physical contact and subsequent requirement for lubrication required by traditional mechanical gearing.

Preliminary overall Cost of Energy (CoE) modelling shows significant advantages from the PDD system when compared to other current machine topologies, with notable advantages in increased efficiency, reducing cost by 2% taking worst case scenarios, high relative annual energy output, reduced mass and reduced maintenance costs.

It is accepted by the consortium that the technology being developed, whilst potentially ground breaking in reducing cost of energy, must be affordable to potential end users once serial manufacturing volumes are achieved. It is estimated that the proposed technology with be within 2.5% of the cost of the current state of the art technology when manufactured in similar volumes for a similar output turbine.

Project name: Wind integrated platform for 10+MW power per foundation

Acronym: WIP 10+

Coordinator: EnerOcean S.L. (ES)

Partners: INGETEAM Services (ES), Ghenova Ingeniería S.L (ES), Tension Tech International Ltd (UK)


The project WIP 10+, “Wind integrated platform for 10+ MW power per foundation” will demonstrate at sea and at significant scale a fully integrated offshore wind floating platform Wind2Power that holds a couple twin wind turbines of up to 6 MW each, and that it is also able to host additional functions due to its size.

The objectives of the innovation are:

1)      To provide a floating foundation for high installed wind capacity

2)      To optimize the O&M procedures

3)      To prove that cost reduction is possible acting both on capital and O&M costs

4)      To improve sea space management

The project addresses the need for cost reduction in offshore wind by providing a light but large semisubmersible platform able to host two 5-6 MW wind turbines for a total of 10-12 MW per platform.

Specific expected results are: validation of numerical and laboratory estimations on forces and motions, proof of engineering design including moorings and wind vanning platform concept. More comprehensive expected results are survivability of the platform through winter conditions in real sea environment, quantification of cost reduction compared to two floating wind turbines, and optimization and validation of specific installation, operation and maintenance procedures.

Project name: Cost of Energy Reduction-Driven Development, Manufacturing and Infield Validation of the World's Largest Offshore Wind Turbine Blade

Acronym: XL-BLADE

Coordinator: ORE Catapult Development Services Ltd (UK)

Partners: LM Wind Power S.L. (DK), Adwen (ES)


Achieving the ambitious EU target of 27% renewable penetration by 2030 requires step-change technological innovations across all sectors of renewables, paving the way for industrialization and scale. Within this context, offshore wind has proven its viability as a mature utility-scale contributor to the EU energy mix, with substantial cost reductions achieved over the past decade, and a similar trajectory as onshore wind towards grid parity.

Within an offshore wind turbine system, the rotor set is one of the most influential ways to reduce total cost of energy. The overarching program objective of the consortium is to reduce the overall offshore wind cost of energy by merging the technological leadership of three offshore industry leaders across three participating countries to design, validate and deploy the world’s largest offshore wind turbine blade.

Specific technological objectives are design, manufacturing and in-field validation of blade approaching 90m in length with aggressive weight targets:

·         Definition of the optimum fibre, resin and laminating process with respect to structural properties, weight and             cost.

·         Tackling industry-plaguing issue of blade erosion through development of new coating and application systems.

·         Characterisation of offshore atmospheric conditions affecting blade erosion, to enable the development of new            coatings.

·         Defining real-scale laboratory tests that reproduce relevant environmental conditions over the operating lifetime          of the blade.

·         Demonstration of the blade technology readiness at the test bench level.

·         Demonstration of project results via field validation in a full-scale offshore wind turbine prototype.

Project name: Wind turbine life-minded production management


Coordinator: Gamesa Innovation and Technology (ES)

Partners: Romax Technology (UK)


The objective of this project is to provide the customers and Wind Farm Operators with extended elasticity so that they can adapt the operation and O&M activities to:

·         The actual Wind Turbine Generator (WTG) wear condition produced by the specific site conditions of the wind          farm and

·         The evolution of electricity prices.

The customer would have the capability to temporarily overpower the wind turbine or alternatively reduce the rate of life consumption in their WTGs to extend actual WTG life expectancy and increase energy production respectively. On top of this the price of electricity would be taken into account so that overpower is preferably applied in times of high prices and fatigue load reduction strategies would be preferably applied in times of low electricity prices.

These new capabilities would provide the customer with increased margins.

In order to achieve this goal new technical developments are going to be integrated and tested in this project:

·         Monitoring of the critical components of the WTG and generation of maps representing life consumption vs              operation conditions, which would provide the WTG control with the information about the wear condition of the        component relative to the expected one.

·         Control strategies aimed at overpowering the WTG and control strategies aimed at reducing fatigue loads on the      WTG components.

·         A control layer aimed at automatically managing the operation of the WTG depending on its wear condition,            electricity prices and wind conditions in order to safely fulfil the general strategy selected by the customer (extend      actual life time of the WTG or maximize the short term economic return)

Lastly, the increased knowledge of the component state achieve through monitoring and the capability to protect the components from excessive wear will reduce the O&M costs as the O&M provider will be able to better adapt their resources and O&M plan to the actual condition of the facility. Additionally, it is expected that the number of critical failures and the number of large corrective actions in the WTG components will be reduced which contributes to the O&M cost reduction and implies an increase of availability.

Project name: Development and demonstration of 'float and submerge' gravity base foundations (FSF) for offshore wind turbines

Acronym: FS FOUND

Coordinator: Blyth Offshore Demonstrator Limited (UK)

Partners: ODSL (UK), EDF R&D (UK), BAM Van Oord JV (NL)


The exploitation of float-and-sink gravity base foundations (FS GBF) has the potential to impact positively upon the development of deep-water offshore-wind farms (>35 metres), resulting in a reduction of the Levelised Cost Of Energy (LCOE) and an increase of deployment of Wind Turbine Generators (WTGs). The project supports the objectives of the EC Wind Energy Technology Roadmap under the SET-Roadmap, which seeks to develop offshore technology through the development of ‘new stackable, replicable and standardised substructures for large scale offshore turbines….and gravity based structures’.

The industry to date has predominantly utilised monopile solutions with jackets and GBFs requiring specialist installation equipment. These foundation types, even if suitable for deeper waters, present a number of challenges to the development of the sector, for example: piling, piling noise, availability and cost of specialist installation vessels. While GBF have been used previously no FS GBF solution has been installed for an offshore wind turbine. It is widely accepted that this type of solution will be required to exploit the potential of offshore wind globally.

The successful demonstration of an FS GBF project would prove the technical feasibility of the solution and enable further refinements of the design for mass manufacture and deployment. The potential benefits of using a FS GBF solution include:

·         Lower installation costs by employing standard tugs and self-buoyancy rather than specialised vessels.

·         Reduced costs deriving from the elimination of piling

·         Reduced environmental impacts through noise mitigation techniques.

·         Lower costs in the mass-manufacturing phase, as personnel costs will be lower in this process.

·         Lower costs during the operational phase as a result of reduced inspection and maintenance.

·         The option to manufacture and deploy the FS GBF in physical proximity to the offshore site.

·         Increased deployment of WTGs in sites where piling is not technically feasible.

DEMOWIND2 funded projects

Project name: Forthwind Offshore Demonstration Project


Coordinator: CIERCO (UK)

Partners: New Waves Solutions (UK), SAITEC (ES)


This first offshore demonstration of the ground-breaking CIERCO technology will provide the opportunity for the validation of some of the key design choices offered by the CIERCO technology, specifically related to foundation optimisation, installation methodology, operation and maintenance process validation and future design scoping for commercial stages of deployment.

The overall technology approach is one which is derived from an integrated design philosophy, focusing on reducing the cost of energy at every phase of wind farm life, from component supply, through installation and commissioning, to operation and maintenance. Radically different design choices have been made, resulting in a reduction of the LCoE of up to25%.

A key component of the integrated design strategy is the novel three-legged truss support structure. The ‘full jacket’ concept delivers an “integrated” design between the normally separate elements of foundation and tower. This project will focus on deployment of the structure with the 2-blade downwind turbine in an offshore environment for the first time. This process will allow for demonstration and assessment of the following:

·         Design, Demonstration and Assessment of the performance of the support structure in combination with wave            domain and turbine loads, including assessment of component lifetime to support the 40-year pro-active O&M          strategy

·         Design and Demonstration of the simplified installation process and assessment of the impact on installation costs

·         Analysis and assessment of the deployment of the CIERCO with different foundation techniques, in different              geological conditions and water depths with the development of an integrated floating design in partnership with      Saitec for full scale deployment in Phase 2 of the Forthwind project.

·         Detailed design, trials and certification of the integrated helideck and Helicopter Landing process to allow                validation of the O&M approach

·         Validation of potential LCOE savings for the large-scale deployment of the technology

Project name: Offshore Wind Accelerator - Wind Farm Control Trials

Acronym: WFCT

Coordinator: Carbon Trust (UK)

Partners: Frazer-Nash Consultancy (UK), Innogy UK (UK), Windar Phototonics A/S (DK), DTU Wind Energy (DK), ECN Wind Energy (NL)


The aim of the Offshore Wind Accelerator Wind Farm Control Trials (OWA WFCT) project is to implement Wind Farm Control (WFC) on an existing full scale offshore wind farm (OWF) and demonstrate better lifetime economic performance through increased power production, reduced O&M costs, and increased availability and lifetime extension of existing and future assets. Recent projects (FP7 ClusterDesign, FLOW program, NREL activities, OWA projects) report promising results with WFC schemes.

The proposed project is designed to combine experts who have played a leading role in concept generation to date (DTU, ECN, Frazer-Nash) and to investigate a range of different WFC approaches in full scale testing. Several measurement systems will be installed, including strain gauges, multiple nacelle LiDARs and one scanning LiDAR. Based on existing experience it can be expected that pitch- and yaw-based WFC will together result in a 0.5-3.5% increase in energy yield and enable load reductions of up to 50% for some wind turbine components. These promising figures are only based on simulation results changing set points and do not require any modifications to the turbine itself: this brings the enormous advantage of the control strategies being realisable on today’s wind farms. However, no solid experimental evidence has yet been publicly disclosed about the performance of WFC schemes in real-life.

Despite the wealth of evidence showing the potential benefits of this technology, technical and economic risks pose a real challenge for bringing this technology to market. The offshore wind industry therefore requires the OWA WFCT project as a catalyst to demonstrate WFC schemes in an operational setting before they can be adopted in the wider industry. Once proven, the concept can be rolled out to operational OWF without any need for further technology development, strengthening the competitiveness of the European offshore wind market.

Project name: Improving Safety and Productivity of Offshore Wind Technician Transit

Acronym: SPOWTT

Coordinator: ORE Catapult Development Services Limited (UK)

Partners: Siemens Gamesa Renewable Energy (UK), Specialist Marine Cons. Ltd (UK), University of Hull (UK), BMO Offshore (NL), Energy Research Centre of the Netherlands (NL), MARIN (NL)


Offshore technicians perform essential service of offshore wind turbines, which is sometimes planned and sometimes an unplanned response to faults. Planning this O&M is challenging because it is difficult to predict the weather accurately enough to judge if the sea conditions will allow the crew transfer vessels (CTVs) to sail and deliver the technicians to the turbine. Currently there is limited information for making this decision. An added challenge is ensuring the safety and wellbeing of the technicians as they are transported in what can be very rough sea conditions, because they have to perform complex tasks once transferred to the turbine.

This project takes a novel approach by using digital technology to create a decision-making tool. Applying psychological and physiological methods from other sectors the wellbeing of technicians as they transit in different sea conditions will be assessed. In parallel the motion of the boat and the underlying sea state will be measured. These data will be combined to create a model, and then a tool, that will support the authority that makes the decision to 1) launch, 2) not launch, or 3) to launch but only with certain control measures.

Optimising how CTVs make use of the ‘weather window’ to deliver technicians will improve O&M productivity and lead to increased turbine availability. When combined, it is estimated that this innovation will lead to a 0.7% reduction in the levelised cost of electricity; equivalent to additional revenue of >€1.2m a year for a 500MW wind farm. Importantly this innovation will not require substantial capital investment by the industry in order for it to have an impact. To make uptake as rapid as possible the ‘model’ created will be open access and will be promoted for use across Europe across the existing and future CTV fleet.

Project name: Offshore Demonstation Blade

Acronym: ODB

Coordinator: Offshore Renewable Energy Development Services Ltd (UK)

Partners: Aerox (ES), National Renewable Energy Centre of Spain (ES), University Cardenal Herrera of Valencia (ES), Siemens Gamesa Renewable Energy (ES), Bladena (DK), DIS (DK), Technical University of Denmark (DK), GEV Wind Power (DK), Netherlands Organisation for Applied Scientific Research (NL)


The economic deployment of offshore wind is a key opportunity to achieve the EU targets for 2030 regarding competitive, secure and low carbon energy supply. The EU-wide target of 27% renewable contribution requires research innovations capable of providing a significant breakthrough in the Levelised Cost of Energy (LCOE). In offshore wind, Operation and Maintenance (O&M) costs represent 16-23% of LCOE (sources: Tavner, Offshore Wind Turbine Reliability; & BVG Associates). Rotor O&M represents an important share of these costs, specifically blade erosion and blade structural integrity. These aspects are tackled by the innovations demonstrated in this project.

Furthermore, rotor aerodynamic performance is a key handle to reduce LCOE, with estimated 1% increase in Annual Energy Production (AEP) trading to 1% reduction in LCOE.

The objective of this project is to reduce the Cost of Energy of offshore wind by demonstrating a set of blade technologies aimed at increasing the rotor energy performance and reducing its O&M costs.
The specific objectives are to integrate in the blades of a research wind turbine the following novel technologies:

CENER - technology#1: aerodynamic low drag add-ons
ODSL - technology#2: leading edge insert for erosion protection
Bladena - technology#3: structural stiffener to prevent damage due to shear distortion
TNO - technology #4: fibre optic sensors to monitor and validate structural stiffener performance
TNO - technology #5: fibre optic sensors to detect leading edge erosion and top coating performance
Aerox - technology #6: High-performance hybrid coating for leading edge protection
Gamesa - technology #7: aerodynamic next-gen blade 100% retrofitable add-ons to increase AEP (decreasing                    LCOE).

The technologies #1 through #6 will be retrofitted to ORE Catapult’s 7MW 171m diameter Levenmouth Turbine. The technology #7 will be tested in a Gamesa turbine (location TBC).

These technologies combined will reduce LCOE by 4.7%.

Project name: Compact Holistic Efficient Floating Turbine

Acronym: CHEF

Coordinator: Seaplace SL (ES)

Partners: Norvento Wind Energy UK Ltd. (UK), Magnomatics Limited (UK)


Floating wind turbines are becoming industrialized solutions, and will prevail with depth as turbine capacity increases, since fixed structures are less effective for depths above 50m. Nowadays the first floating wind turbines are operating, but to have a real impact in the Wind Energy market the main challenge is to reduce their cost.

This project aims at a holistic consideration of a floating wind solution from an early design stage, which will lead to vast savings in the LCOE, in the order of 30% and beyond as it is mass produced. The project will combine a floating platform, the Reduced-Draft (RD) Spar, and a new state-of-the-art 8MW generator, the Pseudo-Direct Drive (PDD) generator, leading to significant savings in foundation, installation, O&M, and decommissioning, also increasing the generator efficiency.

Seaplace and Magnomatics have worked together for some time and decided to join forces in a combined solution. Both concepts (RD spar and PDD generator) compliment in every aspect. The construction is cost-effective (and feasible in floating docks). Assembling can occur at port and transport of the whole unit is feasible in its upright position (mostly due to the reduced draft). Installation is simplified (no sheerleg cranes needed). Maintenance is reduced due to the low accelerations of the RD spar, and the low wear of the PDD. Efficiency is increased thanks to the PDD, the Active Heeling-Compensation system, and the high operational windows of the RD spar. No mechanical gear is needed, and the PDD is so light and compact that reduces the dimensions and therefore the price of the RD spar. Major repairs and decommissioning are also simplified.
