  1. Seasteading – Floating Cities on the High Seas The Seasteading Institute Mission: To further the establishment and growth of permanent, autonomous ocean communities, enabling innovation with new political and social systems. Presented by George L. Petrie Director of Engineering The Seasteading Institute November 30, 2011 San Diego, CA

  2. The Grand Vision – Mega-Cities on the High Seas

  3. Seasteading – First Steps • 2008 – The Institute is Founded by Patri Friedman • 2009-2010 – Developing Strategies to Meet Key Challenges • Engineering • Legal and Political • Economic and Business • 2010-2011 – Activity on Multiple Fronts • Movement Building – over 1,000 contributing members • More than a dozen white-papers and research reports • Extensive national and international media coverage; • CBS, CNN, NBC, BBC, Forbes, Wired, Yahoo.com, etc. • Outreach projects; • Magellan Network, Ephemerisle, Design Contests, Volunteers and Internships

  4. Confronting the Engineering Challenges • Feasibility – Habitability, Maintainability, Sustainability • Configuration – Hull form, Size, Material • Scalability • Modularity • Service life • Cost • Performance – Comfort and survivability at sea • Station keeping – Long term, open ocean • Mooring • Dynamic Positioning • Lazy station-keeping • Protection from extreme seas – Large Floating Breakwater • Renewable energy sources – Solar, Wind, Wave, OTEC • Communication – Wireless, Satellite, Subsea cable, Other? • Location – Finding the most suitable sites

  5. First Feasibility Study - ClubStead • 200-guest floating offshore resort/hotel • 400’ x 400’ cable-stayed superstructure; modular construction

  6. Parametric Analysis of Candidate Configurations • Compare Barge, Ship-shape and Semi-submersible Hull Forms • CapEX and OpEx cost comparisons for four different sizes of each

  7. Operational Limits and Performance Assessment • Compare Barge, Ship-shape and Semi-submersible Hull Forms • Evaluate Comfort and Endurance Limits at Different Locations

  8. Seasteading – Location Study Criteria • Physical environment • Wind speed – average, 90th and 99th percentile • Significant wave height – average, 90th and 99th percentile • Current speed – average, 90th and 99th percentile • Bathymetry • Air temperature – average, 90th and 99th percentile • Sea surface temperature (future enhancement) • Economic and business environment • Proximity to urban areas (assuming high-speed ferry) • Land-based data-link access (possible use of repeater buoys) • Proximity to sub-sea data cables • Per-capita GDP of nearby countries • Regulatory burden of nearby countries • Proximity to shipping lanes (future enhancement) • Legal and political environment • Legal Status (freedom from claim by other nations) • Dangerous regions (pirate-infested waters)

  9. Location Study – Environmental Criteria

  10. Location Study – Overall Results for 2 Scenarios

  11. Near-term Strategy – Conversion of an Existing Hull

  12. New Life for an Old Rig - Stylistic Concept

  13. Extreme Makeover

  14. All The Comforts of Home – in 600 square feet

  15. Dare to Dream!
