FIELD: transport.
SUBSTANCE: invention relates to sea gravity platforms for exploration of oil and gas deposits at continental shelf. Proposed platform comprises submersible offshore platform composed by bottom and top bearing plates, sidewalls and internal bulkheads. Bell consisting of separate sections is hinged to submersible platform bottom part. Every said section comprises vertical wall, stiffness ribs and guide pipes. Stiffness ribs have support elements at the points of abutting on bottom plate. Submersible platform sidewalls includes element for attachment of said bell in transport position and recesses to accommodate retainer pints.
EFFECT: higher stability, low draft, fast assembly and disassembly.
