Abstract

Flytende plattform for boring, produksjon, lagring eller andre anvendelser, særlig egnet for isutsatte farvann, hvilken plattform omfatter - et skrog med ytre sidevegg som i hovedsak er rotasjonssymmetrisk rundt en vertikal senterakse i plattformen og i en nedre ende er lukket med en bunn, - et dekk i en øvre ende av skroget, utstyrt hensiktsmessig i henhold til den påtenkte anvendelse, idet plattformens dypgående er vesentlig mindre enn plattformens diameter og plattformens oppdriftssenter for den neddykkede del ligger lavere enn plattformens tyngdepunkt, særpreget ved at den i hovedsak rotasjonssymmetriske ytterside av skroget inkluderer minst tre seksjoner regnet fra skrogets øvre ende: - en vannlinjeseksjon som har avtagende diameter i retning nedover langs senteraksen, i hvilken vannlinjeseksjon havets vannlinje skal ligge ved operasjon i isutsatte farvann, - en mellomseksjon med sylinderform, og - en underseksjon som har økende diameter i retning nedover langs senteraksen. Fremgangsmåte for operasjon i isutsatte farvann av plattformen.Liquid platform for drilling, manufacturing, storage or other applications, particularly suitable for icy waters, which includes - a hull with outer side wall which is substantially rotationally symmetrical about a vertical center axis of the platform and closed at the bottom with a bottom, - a tire at an upper end of the hull, suitably fitted in accordance with the intended use, the depth of the platform being substantially smaller than the diameter of the platform and the center of buoyancy of the submerged portion being lower than the center of gravity of the platform, characterized in that the substantially rotationally symmetrical surface of the platform includes at least three sections counted from the upper end of the hull: - a waterline section having a decreasing diameter downward along the center axis, in which the waterline section of the ocean waterline shall lie in operation in icy waters, - an intermediate section of cylinder shape, and - a subsection of increasing diameter in a downward direction along the center axis. Procedure for operation in exposed waters of the platform.
