SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

  1. 1. Photo: Max Hurdebourcq Welcome back! Session 2, 21st May 2013
  2. 2. Martin Syvret of Aquafish Solutions Ltd. on behalf of Co-location Project Team May 2013
  3. 3. Reasons & Origin for Project: Why Offshore & Why Wind Farms? North Hoyle Trial; Agreements – Logistics – Results Project Structure: Funding - Project Partners – Duration Deliverable: Aquaculture Opportunities Report Deliverable: Guidance Manual Co-location Case Study Challenges & Follow-on Work Conclusions & Close…
  4. 4. Why Offshore Shellfish Culture: Environment; Increased water flow leading to higher phytoplankton levels & dispersal of detritus Generally superior water quality - Classifications Less impacts of diffuse pollution e.g. faecal run-off from agricul. Lower shellfish disease/pathogen load e.g. oysters Food Safety; Less norovirus / microbial contaminants / HABs Economics & Operational; Inshore = Lack of sites / Competition for space / Visual impact Greater economies of scale with large farms EU & Govt. Stance; Importance now recognised ASP
  5. 5. This is the question that is asked by this sector… Raises revenue for The Crown Estate Efficient use of the marine space Food security Less large traffic through wind farm sites Known environmental and bathymetric parameters Potential exclusion of other activities
  6. 6. Deepdock Ltd. initiative with assistance from Seafish Agreements and procedures: Mussel cultivation trial proposal / Method statement Code of Practice / Operational plan Marine emergency response plan / Risk assessment Vessel Insurance Permission from CCW / Permission from Welsh Government
  7. 7. Mare Gratia operating in the North Hoyle Wind Farm during the 2010 trials
  8. 8. A comparison of the size of mussels taken from samples (around 500) during deposition (20th July 2010) and harvesting (29th September 2010) 0 10 20 30 40 50 60 10 20 30 40 50 60 No. of mussels Mussel size (mm) 20th July 29th September More structured multi-partner approach to future trials agreed…
  9. 9. Funding: Welsh European Fisheries Fund (EFF) & WG 50:50 ratio of Funding to Time CIK from Project Partners 45 days dedicated to deliverable production Project Partners: Includes renewable energy companies, renewable support organisations, conservation agencies, Welsh Government, aquaculture industry + support & trade organisations, NGOs, research organisations, landowners, UK Government organisations Duration: 9-10 Month Project Start date: 01 Oct. 2012 / End date: June-July 2013 Deliverables: Two main reports - Reports guided by Project Meetings, one-to-one interviews, small workshops, planning case-study…
  10. 10. Advisory Group & Stakeholder input on: 1. What the review should cover? 2. Known past studies & trials 3. Identify suitable forms of shellfish aquaculture 4. Permission & tenure 5. Requirements for a safe & compatible approach to shellfish culture in wind farms 6. Nature conservation interests 7. Key policy drivers from all sectors  End point = guidance / recommendations on what shellfish culture types most suitable now or in near future – not MUPS!
  11. 11. Offshore Locations; Site choice dependent on temp. regime, water quality, plankton resource, seed availability, substrate type, depth, current velocity, other uses etc. Farm size likely to be in 10km2+ sites? Offshore Technology; New & innovative equipment designed to operate under extreme environmental conditions Larger spaces allows low density & therefore low impact farm operations with lower unit production costs Increased potential for mechanisation Scale of Production; High capital outlay for these systems means that high output levels required if farms to be economically viable
  12. 12. Buck et. al., 2010
  13. 13. Advisory Group & Stakeholder input on: 1. Infrastructure for shellfish cultivation & installation 2. Husbandry types including deposition and harvesting methods 3. Safe access & development of a Safe Access Protocol 4. Operational compatibility of shellfish cultivn. & wind farm operation 5. Shellfish cultivation & nature conservation interests 6. Emergency procedures  End point =  A practical Manual on how to safely cultivate shellfish in Welsh offshore wind farm sites  Takes into account requirements of wind farm operators & nature conservation designations
  14. 14. 50m Zone 1 - Inner Exclusion Zone MANDATORY Zone 6 - Vessel manoeuvrability Offset RESTRICTION Vessel turning circle Zone 5 - Emergency Response Offset RESTRICTION Distance travelled whilst deploying anchor Zone 4 - Condition Specific Offset RESTRICTION Mooring line length (windage) Zone 3 - Site Specific Offset RESTRICTION Mooring line length (depth/currents) Zone 2 - VMS Offset RESTRICTION Vessel length Note: Zone sizing for illustrative purposes and not to scale. Zone scaling to be vessel, site and condition specific Turbine Structure Principal: There is a need to develop a system for setting risk-based restriction zones Includes: 1 =Inner exclusion core; 2 =Length of vessel; 3 = At anchor drift due to current speed/depth; 4 = Windage/wave induced; 5 =Distance before anchor deployment in emergency; 6 = Vessel turning circle
  15. 15. 650m 850m OPERATIONAL ZONE RESTRICTION ZONE EXCLUSION ZONE X4 turbines for illustration Turbine separation W-E = 850m Turbine separation N-S = 650m 650m
  16. 16. WFO risk perception with ‘Christmas tree’
  17. 17. Key: Fixed gear aquaculture Seabed culture (e.g. seed mussel) Scour protection (AR ranching – e.g. lobster) Fishing – dredging zone Conservation – monitoring zone
  18. 18. Marine parks and nature conservation spatial pressures are drivers for co- location or multi-functional use Marine Spatial Planning is advanced and has shown how limited the space resource now is in German waters Many Wind Farms 60km+ offshore and so face challenges with depth
  19. 19. Dredging not allowed within offshore sites & so targeting fixed gear aquaculture e.g. rope-mussels, cage culture of oysters Mussel spat availability is constant when settling on ropes Connecting equipment to and away from wind turbines has been considered
  20. 20. Figure (A) shows map of the area displaying18 offshore wind turbines & 6 single mussel plots designated by wind farm company Figure (B) presents a design of a single mussel plot within a group of four wind turbines (not to scale) (Source: Buck, B. H. , Ebeling, M. and Michler-Cieluch, T. (2010). Mussel Cultivation as a Co-Use in Offshore Wind Farms: Potentials and Economic Feasibility, Aquaculture Economics and Management 14(4):, pp. 1365-7305 ) Construction: Was due 2011, now planned for 2015, permit may be sold…
  21. 21. Limitations; No risk assessments carried out of WFO vs. aquaculture e.g. drifting rope-mussel lines Experience so far is only with working at Pilot-scale studies i.e. extrapolation to commercial-scale is still theoretical Environmental impacts, nutrient flux research etc. is through tank-based research only Research Need; Commercial-scale research trial required to provide real data: To test theoretical assumptions of environmental & ecological research To ground-truth models and economic predictions To investigate operational practises and test equipment and techniques To investigate the potential for Co-Management International co-operation & funding to meet this need?
  22. 22. Policy Drivers - German experience; Lots of discussions about benefits of co-location but for years there has been no progress on implementing practical projects Recently changed due to the introduction of a law/regulation WFDs must investigate prospects for co-location when submitting an application for a permit to develop a wind farm No investigation (even if result is negative) = no permit Demonstrates the need for Top Down intervention!
  23. 23. Why should the WFDs/WFOs get involved; What is in it for them? “The challenge to developing offshore co-location is not technical but revolves around the ability to persuade WFDs/WFOs to work with the aquaculture sector” (Prof. Bela Buck, AWI Institute) How to persuade the WFOs to co-locate; Socio-economic study: ‘Community Benefit Fund’ applicability informed by study Scoping overview for this socio-economic study is planned and seeking funding WFDs to become the developer of choice!
  24. 24. Successful Co-location of WFs & Aquaculture TOP DOWN APPROACH Policy drivers – Requiring and/or Incentives – Encouraging Role for Defra / WG / MMO / TCE BOTTOM UP APPROACH Requires - Industry Interest / Investment / Know-how Investment – Supported by Funding Commercial-scale Trials to test; • Theories/Models • Environ. impacts • Operational aspects • Technical challenges • Ecosystem services • Economics Socio-Economic Study to; Highlight & Quantify potential wider benefits of co-location
