A fluid contact tray (10) for a mass transfer column, in particular a vapor-liquid contact tray suitable for the use in an offshore fractionation column, comprises: - a tray deck (12) comprising an active mass transfer surface (20) suitable for contacting two fluids of different densities, wherein the active mass transfer surface (20) comprises one or more orifices (18) for the passage of a fluid, and wherein at least two at least partially radially extending separation walls (22) and/or at least one separation weir are arranged on the active mass transfer surface, which divides the active mass transfer surface into at least two sections, - an annular channel (26) suitable for collecting fluids, which is arranged at the peripheral area of the active mass transfer surface and at least partially embraces the mass transfer surface, - a central downcomer (34) for collecting and discharging a fluid from the annular channel and - at least one conducting means (40) for transferring fluid collected in the annular channel from the annular channel to the central downcomer. This fluid contact tray is in particular useable for offshore applications, such as for a fractionation column located on a FLNG or FPSO vessel.
