collaboration by sharing operational windfarmdata to support improvements in the availability, reliability and performance of offshore wind assets. SPR and Vattenfall are active contributors to the project and SPR will be sharing operational data fromitsWoDS windfarm(once fully operational later) in 2014. The impact of this project will be greater sharing of knowledge across the industry to improve offshore assetmanagement and reduce the cost of energy. [I2,I6,S5] {ii,iii}


3.2.4 Package specific action:


 First significant deployment of the latest state of the artWTGs: Each of the turbines shortlisted by EA1 has not been deployed offshore yet and each incorporates significant levels of technical innovation and should reduce LCOE (compared to lower ratedWTGs) by between 10% - 15%. Examples of innovation are summarised in Annex 2.[redacted] [I1,I2,I3,I4] {ii, iii}


 Nacellemounted LiDAR: A notable innovation by the shortlistedWTG suppliers is the prospect of trialling nacellemounted LiDARs to provide amore accuratemeasurement of the wind speed in front of the rotor which can be linked with theWTG controller to potentially reduce fatigue thrust loads which could result in a reduction in foundation costs.[I2] {ii, iii}


Foundation design, fabrication & installation 3.2.5 Industry wide actions


 Monopile chalk deployment research: SPR is the lead project partner in establishing a collaboration with Imperial College London and Geotechnical Consulting Group to develop new design procedures for the use ofmonopiles and jackets in chalk and has been successfully awarded grant support fromthe Technology Strategy Board’s (TSB) “Infrastructure for Offshore Renewables” call. Such new design standards will be particularly beneficial for future offshore wind development in Northern Europe where chalk is a common ground condition. [I2] {ii, iii}


 Suction bucket foundation: SPR is supporting the first full scale demonstration of a suction bucket jacket foundation to be installed in 2014. This foundation offers a potential cost saving alternative to jacket pile installation solutions and could be employed in future EA Zone projects. [I4] {ii, iii}


 Pile soil analysis project: SPR is playing a leading role in a Pile Soil Analysis project through its connectionwith the OWA with the aimof improving design standards for XLmonopiles to enable this solution to be used in deeper water with larger turbines which has significant cost reduction potential. This project also offers the potential to improve jacket design standards. [I4,I6] {ii, iii}


3.2.6 Package specific actions EA1 will foster innovation in the foundations package via the following: [I2,I4,I5,I6] {ii, iii}


 Placing one of the largest ever orders for jacket foundations in themarket with up to two suppliers, this will help support the investment plans of certain fabricators to increase capacity and purchase state of the art tooling equipment


 Collaborating closely with the chosen fabricator(s) to investigate how the design can be optimised for fabrication & steel weight


 Workingwith suppliers to introduce volumemanufacturing techniques andmethods to reduce production times,manufacturing efficiency, quality and reduce LCOE.


 Using lessons learned fromthe Ormonde project to informEA1’s approach to design standards and promote a serial production ethos to fabrication


 Maximising the opportunity within the tier 2 and 3 supply chain to standardise their offering for primary and secondary steelmaterial (pipes & tubes)


 Challenging its installation provider to optimise the installation plan using the latest vessels and installation techniques


Array cable EPCI 3.2.7 Industry wide actions


 OWA Cable TechnicalWorking Group: SPR and Vattenfall are part of this work group focused on array cable innovation. This project aims to qualify a number of 66kV cables so they are commercially available by the end of 2015 which will be beneficial to projects such as EA1 amongst others [I1, I2] {ii, iii} Page 19 of 30
