A marine platform comprises a caisson unit adapted to be placed onto the submarine ground at a desired offshore site. A tower-like tubular structure comprising a plurality of columns extends vertically upwardly from said caisson unit and with their lower ends integrally fixed to said caisson unit. A deck unit adapted to be provided with petroleum drilling equipment or the like is integrally fixed to the upper ends of said columns. A floating unit is adapted to be displaceably and removably fixed to said columns.
