Tube of riser has one end capable of resting against sea bed and upper part of tube is tailored for passage through limiting hole in bottom of platform. Tube includes unit of ball-and-socket joint and coupling anchored for withdrawal in bottom of platform, in limiting hole, and branch pipe fixed with center part in ball-and-socket joint. Tube of riser located in branch pipe is fitted with liners compensating for wear. EFFECT: installation of support with riser on bottom of platform that can be easily removed or replaced. 5 cl, 6 dwg
