Abstract:

A large deck area floating platform with wave attenuating outriggers provides equivalent payload and deck operating area to a fixed, piled, and jacketed platform alternative for coastwise and offshore applications. The floating platform integrates large deck areas for industrial applications with a main ship-shaped hull and a submersible system of outriggers and column risers to form a stable, transportable, and structurally sound industrial facility that may be tuned hydro-dynamically to attenuate wave forces on the moored structure. The platform provides from 2 to 10 acres of weather deck and associated superstructure space, a ship-like hull, and direct subsea access via enclosed areas between the main hull and outriggers. Through the medium of differential ballasting, the displacement and freeboard of the facility may be adjusted to maintain hydro-dynamic tuning for changing wave conditions or to provide additional freeboard for storm survival.
