Sevan Marine AS has developed a new mono-column concept for an FPSO. Its circular shape assures that, no matter from which direction the weather might come, the hull will always present the same surface area to it, becoming indiferent to environmental forces direction changes. The SSP has being through extensive model testing and has shown exceptionally low movement characteristics, and since she is based on the same flotation principles of a ship the SSP is, besides intrinsecally stable, of easy construction and low cost, allowing for great variable deck loads and storage. The SSP also features double hull, and no piping in the tanks, allowing for safe and environmentally friendly operations.
