A floating construction (11) such as for instance a SPAR buoy, which is connected to the seabed (32) by tethers and/or risers (15, 16). At the top part the floating construction (11) comprises a displacement member (17') mounted on a mounting frame (17). Two risers (15, 16) and/or tethers that are placed on respective sides of a vertical center line (22) of the mounting frame (17) are connected to the displacement members for causing oppositely directed and substantially equal displacements thereof upon tilting and/or the sideways excursion of the floating body (11). Hereby a substantially similar tension in the connecting elements (15, 16) is maintained. In one embodiment displacement member comprises a pivotable arm (5) or pivotable deck structure connected near the upper end of the floating body to provide a dry tree. Alternatively the displacement member may comprise pressure fluid cylinders (39) or a cable construction (51, 52). Preferably the floating construction is at its lower end provided with a pivotable guide casing to cause a gradual bending of the riser and/or tethers.

1. Floating construction (1,11,58) comprising a floating body (9,13,61,92) having a lower part (18,67,100) extending below water level and an upper part (14,36,66,97) extending above water level, the floating body being connected to the sea bed by means of at least two substantially parallel connecting elements (3,4; 15,16; 59,60,64,65) extending in a substantially straight line between the sea bed and the floating body, characterised in that the floating body comprises a mounting frame (6,17,35) to which upper parts of the connecting elements are movably attached so as to be movable relative to the mounting frame, and a displacement member (5,17'; 39,40; 50,51,52; 56,63) attached to the mounting frame and to end parts of the at least two connecting elements (3,4; 15,16; 43,44; 59,60; 64,65) that are placed on respective sides of a vertical center line (22,41,106) of the mounting frame, the displacement member being adapted to cause oppositely directed and substantially equal displacements of the connecting elements, in the length direction thereof, relative to the mounting frame upon tilting of the floating body to maintain a substantially similar tension on the connecting elements, the upper part remaining above water level.
