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”


Float Inc. PSP Technology

Characteristics Validated & Confirmed

Stable with Variable Deck Loads Capabilities

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.

Wave attenuation

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

Modules assembly can be accomplished in Sea State 3 levels


Float Inc. PSP Technology

Characteristics Validated & Confirmed

Monolithic platform Modular construction and assembly

Extensible PSP modular construction permits extension of existing PSP

without interruption of existing activities onboard

Mobile PSP can be repositioned to a different area/zone as the PSP is

simply retained in position by the appropriate anchorage system

Long life 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.

Some pics/ideas for

Oceans Offshore Energy System

Offshore Ocean Energy System proposed and presented by


Float Inc Offshore Ocean Energy System (OOES)

accommodates onboard the

Pneumatically Stabilized Platform (PSP)

Offshore Wind Energy

Offshore Wave Energy

Offshore Ocean Current Energy

Potential Energy Storage (PES)

Ancillary Applications: Aquaculture & related

activities

Desalination plant

LNG Liquefaction & Re-gasification Facilities

Offshore Ro-Ro and/or Container Port

NB: Not an exhaustive list

All on the same Platform - PSP


Offshore Wind Turbine Farm

onboard the Float Inc

Offshore Ocean Energy System (OOES)

Structural stability that allows any standard Offshore Wind Turbine to be easily deployed.

Wind Turbine foundations same as onshore

Access, maintenance and operation similar to onshore

Transformer station in-the-dry

Storage of spare and repair parts

No new specialized vessels needed to transport equipment or personnel directly from ports to platform
