FIELD: hydraulic engineering; applicable in development of continental shelf, mainly, on shallows. SUBSTANCE: platform has within its outline, rectangular displacement pontoon and trestle with equipment mounted thereon. Displacement pontoon length equals at least 0.25 and not above 0.48 of the total length of pontoon, and its width exceeds the pontoon width on its maximum midsection. The total length of pontoon amount at least eight depths of sea in point of platform operation. EFFECT: reduced metal specific content of platform and higher operating reliability of platform landing on ground due to shape of displacement pontoon. 3 dwg
