A Scoping Study On: Research Into Changes in Sediment Dynamics Linked to Marine Renewable Energy Installations

Thorne3, Judith Wolf3 April 2009 1British Geological Survey Murchison House West Mains Road Edinburgh EH9 3LA [email protected] www.bgs.ac.uk 2Partrac Ltd 141 St James Rd Glasgow G4 0LT [email protected] www.partrac.com 3Proudman Oceanographic Laboratory Joseph Proudman Building 6 Brownlow Street Liverpool L3 5DA, www.pol.ac.uk 2 EXECUTIVE SUMMARY This study scopes research into the impacts and benefits of large-scale coastal and offshore marine renewable energy projects in order to allow NERC to develop detailed plans for research activities in the 2009 Theme Action Plans. Specifically this study focuses on understanding changes in sediment dynamics due to renewable energy structures. Three overarching science ideas have emerged where NERC could provide a significant contribution to the knowledge base. Research into these key areas has the potential to help the UK with planning, regulation and monitoring of marine renewable installations in a sustainable way for both stakeholders and the environment. A wide ranging consultation with stakeholders was carried out encompassing regulators, developers, researchers and other marine users with a relevance to marine renewable energy and/or sediment dynamics. Based on this consultation a review of the present state of knowledge has been produced, and a relevant selection of recent and current research projects underway within the UK identified to which future NERC funded research could add value. A great deal of research has already been done by other organisations in relation to the wind sector although significant gaps remain, particularly in long term and far-field effects. -

Agenda Item No. 5 Pieter Montyn E.ON Climate & Renewables UK Cabinet Member for Highways and Transport Rampion Offshore Wind Limited Cabinet Office Westwood Way Ground Floor Westwood Business Park County Hall Coventry West Midlands Chichester CV4 8LG West Sussex www.eon-uk.com PO19 1RZ Chris Tomlinson 01273 603 721 3 December 2013 07815 141 008 Dear Mr Montyn, Rampion Offshore Wind Farm Thank you for your letter dated 14 November 2013 seeking clarity on issues regarding the Rampion offshore wind farm. I respond to each issue in turn. 1. Benefits and facilities for local people The overarching benefits of the Rampion Offshore Wind Farm are to create safe, secure, clean energy to help secure our energy supplies and keep the lights on, while tackling climate change through reducing carbon emissions and creating jobs during construction and operation. In addition to these core benefits, our policy is to ensure that we are a good neighbour to the local community, to continue our track record on existing offshore wind farms of working with communities and supporting local projects and education initiatives. To achieve this, we will develop relationships with Sussex communities and consider the potential to provide initiatives through community benefits funds. Our plan to deliver community benefits is intended to support initiatives in those communities associated with the offshore and onshore elements of the Project. The exact geographical scope and distribution of such initiatives need to be very carefully considered in view of the spatial extent of the Project. We intend to consult the wider community through a number of existing communication channels that we established for the Agenda Item No. -

Community Benefits from Offshore Renewables: Good Practice Review
Community Benefits from Offshore Renewables: Good Practice Review David Rudolph, Claire Haggett, Mhairi Aitken, University of Edinburgh Executive Summary Overview This project evaluates existing practices in community benefit models for offshore renewables. We identify and evaluate national and international case studies of different community benefit models, and provide evidence of how community benefits are delivered and distributed. In particular we consider the key relationship between how communities are identified, how impact is perceived, and how benefits may therefore be apportioned. We then assess the different mechanisms and schemes of benefit-sharing to identify good practice and key points of learning for Scottish policy and planning. The full report can be found at Community Benefits from Offshore Renewables: Good Practice Review. Key findings Evidence for community benefits from offshore renewables is rare. The UK leads the way in delivering benefits, although this is largely ad hoc, voluntary, and varies between developers. The Scottish Government is alone in explicitly considering distribution of the local and national benefits beyond the delivery of supply chain benefits. The way in which community, benefit and impact are understood are crucial in determining whether or how benefit should be apportioned and delivered; and these definitions are closely connected to each other. We detail in the report the range of ways in which benefits are provided; and find that community funds are the most common approach. ClimateXChange is Scotland’s Centre of Expertise on Climate Change, supporting the Scottish Government’s policy development on climate change mitigation, adaptation and the transition to a low carbon economy. The centre delivers objective, independent, integrated and authoritative evidence in response to clearly specified policy questions. -

Structural Integrity of Offshore Wind Turbines
TRANSPORTATION RESEARCH BOARD Structural Integrity of Offshore Wind Turbines SPECIAL Oversight of Design, Fabrication, and Installation REPORT 305 Special Report 305 Special Report The United States is poised to begin building its first offshore wind energy power projects. To facilitate the orderly development of offshore wind energy and support the stable economic development of this nascent industry, the United States needs Structural Integrity a set of clear requirements that can accommodate design development. In this study, sponsored by the U.S. Department of the Interior’s Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE), the committee recom- of Offshore mends that BOEMRE develop a set of performance requirements that establish goals and objectives with regard to structural integrity, environmental performance, and energy generation. Because the committee found that the risks to human life and the Structural Integrity of Offshore Wind Turbines Wind Turbines environment associated with offshore wind farms are substantially lower than for other industries such as offshore oil and gas, it suggests that an approach with significantly less regulatory oversight may be taken for offshore wind farms. Under this approach, indus- Oversight of Design, try would be responsible for proposing sets of standards, guidelines, and recommended Fabrication, and Installation practices that meet the performance requirements established by BOEMRE.

However, any large construction project will have environmental impacts so it is imperative that they be located and built in an environmentally responsible way. As interest in constructing renewable energy generation facilities in offshore locations increases, regulators need to ensure that adequate measures and controls exist to keep adverse marine environmental impacts to a minimum. Regulators in different countries are facing the same challenges but to date have been progressing on their own with very little exchange of experiences. This has led to duplication of effort and the unintentional withholding of important data sets from the wider scientific community. This workshop of 63 delegates was convened to bring together for the first time regulators, NGOs and other stakeholders with an interest in marine environmental impact assessment from around Europe to share experiences and discuss best practice for offshore renewable technologies. Although it had the broader heading of offshore renewable energy the discussions focussed on wind power as this
