Framework and offshore support structures made thereof

A floatable, toroidal-segment pontoon configured for building a toroidal floating body constructed from a plurality of the toroidal-segment pontoons, the toroidal floating body having a torus eye containing a torus axis of rotation, wherein each of the plurality of toroidal-segment pontoons comprises:

• connecting means on two substantially flat side surfaces of each of the plurality of toroidal-segment pontoons, wherein the connecting means are designed in such a way that adjacent pontoons of the plurality of toroidal-segment pontoons can be joined in a positive-fitting manner in an axial direction, with the connecting means configured on a first side surface as at least one groove extending substantially radially, axially or obliquely in a radial direction, and on a second side surface opposite the first side surface the connecting means is configured as at least one substantially complementary tongue opposite the at least one groove;
• receiving areas on at least one radially inner pontoon surface for receiving a component in the torus eye;
• and
• retaining means arranged on at least one radially outer pontoon surface for holding adjacent pontoons of the plurality of toroidal-segment pontoons together in a torus circumferential direction and in the radial direction;
• wherein at least one of the retaining means and the receiving areas is configured in a form of a groove or a slot extending circumferentially from the first side surface to the second side surface on the at least one radially outer pontoon surface or on the at least one radially inner pontoon surface, respectively;
• and
• wherein each of the plurality of toroidal-segment pontoons is made of plastic.
