FIELD: construction.
SUBSTANCE: platform comprises a body, a foundation part with a bottom slab equipped with ribs embedded into the foundation soil. At the same time the foundation in its lower part along the entire perimeter at the outer side is equipped with ploughshares with depth of submersion and distance between them determined on the basis of the given expression. The ploughshare width is also made from the mathematical expression.
EFFECT: reduced material intensity in development of a marine gravity platform, reduced volume of ballast for provision of ribs embedding into the foundation soil, increased stability and bearing capacity of the soil foundation, increased reliability and reduced risk of loss of gravity platform stability during the period of operation under action of combined external impact of loads.
