Abstract

A self installing offshore platform 1, designed for use in the sea as a substation for offshore wind parks but also usable in oil and gas recovery, of the type that includes multiple lower pontoons 5 arranged in a spaced relation or connected, e.g. in a ring, and at least three columns 10 mounted in the lower end regions thereof to the pontoons 5 and mounted in the upper end regions thereof to a platform deck structure 15. A ratio of the volume of pontoons 5 to the volume of columns is in the range of 0.8 to 1.5.
