  • 3. Float Inc. PSP Primary Design as a Deep Ocean Offshore Floating Platform  Defense Advanced Research Project Agency (DARPA)  Confirmation of PSP technology (1995 – 1996)  Office of Naval Research (ONR)  Validation of PSP technology characteristics (1997 – 1998)  Float Incorporated Pneumatically Stabilized Platform (PSP) technology chosen for inclusion in a national R&D program U.S.A. - Department of Defense “Mobile Offshore Base Program” 02Oct2012 www.floatinc.org 3
  • 4. Float Inc. PSP Technology Characteristics Validated & Confirmed  Stable with Variable Deck Loads Capabilities   Wave attenuation    At-sea motion stability and structural loads mitigation by decoupling the “hull” from ocean wave pressures through the use of air buoyancy, which is both compressible and mobile within the PSP platform cylinders. Tank testing incident wave Heights up to 20meters Range of transmitted wave reduction = 50% to 94% Modular   PSP cylinders assembled into modules (25 cylinders) Modules assembled into PSP platform configuration  02Oct2012 Modules assembly can be accomplished in Sea State 3 levels www.floatinc.org 4
  • 5. Float Inc. PSP Technology Characteristics Validated & Confirmed  Monolithic platform   Extensible   PSP can be repositioned to a different area/zone as the PSP is simply retained in position by the appropriate anchorage system Long life   02Oct2012 PSP modular construction permits extension of existing PSP without interruption of existing activities onboard Mobile   Modular construction and assembly PSP is constructed of post constraint, reinforced concrete having a useful life exceeding 50-years. No dry-docking required, and requires no significant maintenance of the basic hull. www.floatinc.org 5
