摘要

Floating platform structure comprising a deck section and a support section supporting the deck section. The floating structure is manufactured in the shape of a trussed girder having an upper chord and a lower chord which are connected with one another by girder members and having a vertical cross section substantially in the shape of a triangle having an apex pointing downwardly, the deck section of the platform structure being provided by the upper chords of the girder. The buoyancy means of the platform structure are found in the upper portions of the girder members and the ballast means in the lower portions of the girder members and optionally in the lower girder chord. The support section comprises groups of at least three girder members each, said members converging from the deck downwardly towards a common point and being fixedly connected with one another in a junction point in or adjacent the convergency point. In an advantageous embodiment of the invention each group of girder members comprises four members presenting an upside down orientated pyramid, and two of the girder members in each pyramid meet two corresponding girder members of an adjacent girder member pyramid or group at the deck section.
