FIELD: oil and gas industry.
SUBSTANCE: platform consists of a cylinder-shaped semisubmersible hull placed vertically above and below the sea level. The platform hull has a concave part, which reduces its cross-section area. The concave part is formed discretely at the outside peripheral surface of the platform hull, at that the depth of the platform submersion is regulated so that in extreme sea conditions the water line is at the concave part level.
EFFECT: preventing vertical resonance of the platform in extreme sea conditions due to increase of free oscillation period for the platform heaving.
