The invention relates to a flexible suspension arrangement for counteracting bending moments of a riser (3). The suspension arrangement (1) comprising at least three plates (12, 13, 14) of which a middle plate (13) is located between a top plate (12) and a bottom plate (14), said top plate (12) is hingedly connected to said middle plate (13) and are adapted to tilt about a first horizontal central axis (21), said bottom plate (14) is hingedly connected to said middle plate (13) and adapted to tilt about a second horizontal central axis (20) arranged perpendicular to the first horizontal central axis (21). The upper middle plate (13) having an upper plane (13a) defined by the upper limitation of the middle plate(13), said middle plate (13) having a lower plane (13b) defined by the lower limitation of the middle plate (13). The first and second horizontal axis (21, 20) are arranged in horizontal planes arranged at said upper plane (13a) and at said lower plane (13b) or arranged in between said upper plane (13a) and said lower plane (13b). The invention also relates to a jacking system for use with the flexible suspension arrangement. The jacking system comprises at least four levelling jacks (16) located between the top plate (12) and bottom plate (14), said levelling jacks (16) are fixed in a first end to one of said top plate (12) or said bottom plate (14). In the other ends the levelling jacks (16) are adapted to abut the opposite of said top plate (12) or said bottom plate (14), without being attached thereto.
