The SSP (Sevan Stabilized Platform) is basically a mono-hull with circularshape, depending on the same stability principles as a ship-shaped vessel. TheSSP-300 refers to one SSP hull size, capable of storing 300,000 barrels ofcargo. Differently than the SPARs, the SSP is wider than her vertical height, with an operational draft that is typically less than one third of herdiameter. The circular shape dispenses the unit of any heading changes, sincethe seas face the same vessel hydrodynamical resistance, whichever directionthey are coming from. Consequently, the SSP does not need turrets nor swivels, in order to handle the incoming oil flow, having the option of receiving therisers through a central moon-pool, while maintaining a spread-mooring systemseparately deployed from her outer hull. The design also includes important safety features, like double bottom anddouble sides, which allows for segregated ballast and offers structuralstrengthening. The highly symetrical shape is also conducive to modularity anda good stress distribution throughout the hull, preventing fatigue stressconcentration and doing away with the need of using high grade steel. Theresult is that the hull is composed of a small number of different constructionmodules, used repeatedly, and a lower steel density for the hull, whichtranslates readily into smaller construction cost and yard time. The SSP not only offers all the advantages of a regular ship-shaped vessel -like large storage capacity, big deck load, and spacious deck area - but hasmotion behaviour similar or better than a semi-submersible hull. Constructionis facilitated by the intrinsic symmetry, which also offers access to all tanksfrom a central position, thus reducing piping and cabling. This paper willaddress these, and other features of the SSP (including the structuraleconomies allowed by the design), describing a concept design that can beconstructed virtually anywhere, and with enough robustness to competesucessfully in a wide range of applications, throughout the world.
