Integrated production complex on a gravity-based structure (gbs)

1:

• A production complex for hydrocarbon processing which comprises a gravity-based structure (GBS) and topside modules with process equipment located on it, the GBS has a rectangular top slab and a rectangular base slab, an intermediate horizontal slab, vertical walls, at least one compartment with a tank to store hydrocarbon and/or processed product, and at least one ballast compartment, the GBS top slab has supports, on which the topside modules are mounted, wherein the GBS has a central part and a protruding part, with the central part having form of a rectangular prism with the said top slab, and the protruding part stretching along the central part sides all around its perimeter and having external vertical walls, the GBS protruding part and central part share the said base slab, with the protruding part being lower in height than the central part, the GBS central part has longitudinal and transverse walls that form compartments, at least one of which accommodate the said tank, while some of which are ballast compartments, and the protruding part has internal walls that are perpendicular to its external walls and form compartments, some of which are ballast compartments.
