Abstract

Et halvt nedsenkbart fartøy (10) er innrettet for å motstå stampebevegelse, og innbefatter et antall bæresøyler (16) som hver har en øvre ende (19) og en nedre ende (23) . Et dekk (3 9) er forbundet mel-lom antallet bæresøyler (16) ved posisjoner på søylene (16) som befinner seg i nærheten av de øvre ender (19). Dekket (39) er en kasseformet struktur. En ringpontong (43) er forbundet med antallet bæresøyler (16) ved posisjoner i nærheten av de nedre ender () av hver av søylene (16). Hver bæresøyle (16) har en langsgående akse (29) som skråner oppover og inn-over fra ringpontongen (43) til dekket (39), og den langsgående akse er orientert hovedsakelig radialt fra et midtpunkt (13) for fartøyet (10). En helningsvinkel for bæresøylene (16) nærmer seg minst 5 grader fra vertikalen. Ringpontongen (43) har en rektangulær form, og er i en variant hovedsakelig kvadratisk formet og har hjørnepontongpartier (49) som er forbundet med hverandre ved hjelp av langstrakte pontongpartier (56) . Den kvadratisk formede ringpontong har en senterlinje (73) som skjærer midtpunktene (79) for vertikalt tatt tverrsnitt (76) gjennom den kvadratisk formede pontong (43) . De langstrakte pontongpartier (56) omfatter fire kasseformede strukturer (59), som hver har en hovedsakelig firesidet form i et vertikalt tatt tverrsnitt.A semi-submersible vessel (10) is adapted to resist tamping movement, and includes a plurality of support columns (16) each having an upper end (19) and a lower end (23). A tire (39) is connected between the plurality of support columns (16) at positions on the columns (16) located near the upper ends (19). The tire (39) is a box-shaped structure. An annular pontoon (43) is connected to the plurality of support columns (16) at positions near the lower ends () of each of the columns (16). Each support column (16) has a longitudinal axis (29) which slopes upwards and inwards from the ring pontoon (43) to the deck (39), and the longitudinal axis is oriented substantially radially from a center point (13) of the vessel (10). An angle of inclination of the support columns (16) approaches at least 5 degrees from the vertical. The ring pontoon (43) has a rectangular shape, and in a variant is substantially square shaped and has corner pontoon portions (49) which are connected to each other by means of elongate pontoon portions (56). The square-shaped ring pontoon has a center line (73) which intersects the midpoints (79) of vertically taken cross-section (76) through the square-shaped pontoon (43). The elongate pontoon portions (56) comprise four box-shaped structures (59), each of which has a substantially four-sided shape in a vertically taken cross-section.
