Overview of Offshore Renewables
Nick Medic, RenewableUK ‘United Kingdom: the world’s leading offshore wind energy market’ is an overview of the sector in the UK, with emphasis on understanding the achievements and challenges, and the actions being undertaken by industry and Government to ensure offshore wind energy achieves its full potential.

Renewable Energy Cable Industry – Going the Distance
Rob Grimmond, OMM A summary of the Cable Renewable Industry requirement of cable survey, installation and additional requirements. This will summarise the lessons learnt on the cable industry and some techniques within the cable. It will give you an understanding of the offshore renewable cable industry that is dealing with the offshore operational requirements of todays market.

14:00– 14:20
Lunch & Exhibition PM SESSION Metocean Requirements for Near-Shore Wave Farms
Ian Harris, Aquamarine Power An accurate knowledge of the wave climate is fundamental to all areas of wave farm development and operation. In the development stage, an understanding of the long term climate is critical for design, energy production estimates and installation planning. This information is provided through long term hindcast models.
In the operational phase, high accuracy forecasts are required in order to plan operations and maintenance activities, provide advance warning of extreme wave events, tune the device to optimise performance and provide power generation forecasts to the grid.
Wave farm developers will therefore be required to transform the wave climate from the deep water forecasts into the near-shore. This will promote a market in fully spectral wave forecast data.

Scour of OWT Foundations
Duncan Talbert, MMI Engineering A wind farm operator commissioned research into the consequences of scour around offshore wind turbine monopile foundations. The depth of scour raises two issues; firstly a potential reduction in the overall stiffness of the foundations, which could in turn lead to problems due to resonance of the turbine and structure; and secondly the structure’s overall stability may be compromised.
The collected data included; design parameters, accelerometer outputs from the turbine’s condition monitoring systems and topographical information gathered by divers in the field. Computer models of the structures which were then calibrated using observed data to give increased confidence in their accuracy. The results from the resonance analysis were used to define scour limits such that the vibration of the OWT remained within allowable limits contained in design standards. The strength analysis defined a further set of scour limits such that the foundation retained the required capacity. The study also concluded that there is the potential to gather further information regarding the depth of scour and the vibration of the OWTs to facilitate refinement of the model.
Preparation of a Geophysical/Geotechnical Guideline to aid Mitigation of Commercial and Safety Risks in Offshore Renewable Energy Developments – an update
Mick Cook, Director, MCL and Chairman, IECO The exponential increase in offshore wind (and to a lesser extent waves and tidal) renewable developments that has occurred over the past few years is probably the most significant change to sea area use since the offshore oil and gas boom of the 1970’s and 1980’s. A critical part of any such development process is the understanding of the shallow soils and foundations both for turbines/structures and power cables and for their design and subsequent installation. The Society for Underwater Technology (SUT), Offshore Site Investigation and Geotechnics (OSIG) committee is currently preparing industry guidelines for the use of geophysical and geotechnical data for offshore renewable project development. This paper will provide an update on progress to date . The presentation will also indicate where this new guideline has built on the information included in pre vious offshore site investigation guidelines for other, different applications. It will also highlight some of the unique issues that have been identified in offshore renewable projects and how these are being addressed in the guideline.
Ocean fronts as an indicator of marine animals: expediting site selection and survey for offshore renewables
Peter Miller, PML We have studied the distribution of oceanic fronts observed by satellite as a proxy for enhanced pelagic biodiversity. These maps can then be applied to assist in the designation of Marine Protected Areas (MPAs) and site selection for marine renewable energy installations (MREIs). It is already known that frequent front zones are associated with higher abundance and diversity of phytoplankton, zooplankton, certain pelagic fish and megafauna such as cetaceans and basking sharks. A 10-year time-series (30,000 satellite images) was processed and aggregated to generate a front climatology of the UK continental shelf, indicating the regions where strong fronts are most frequently observed during each season. A UK government (Defra) project has used these results to advise the selection of potential MPAs.
Renewables Training Network
Steve Green , RenewableUK With the opportunity for employment growth in Renewable Energy over the coming decade, The RTN is engaged in a range of activities designed to ensure that skills gaps do not become a barrier to growth. This presentation will outline some headline figures, alongside providing a background into initiatives already being undertaken to address this key issue
