Abstract (en)
[origin: WO8304061A1] Artificial island or work platform comprising a pontoon or work floor (2) and at least three columns (3), displaceable in vertical direction with respect to the pontoon respectively the work floor (2) and attachable thereto. The columns (3) have in essence a multi-angular horizontal cross section and comprise a toothing on at least on vertical longitudinal rib (9), cooperating with locking beams of a clutching and clamping mechanism (4, 5, 14) movable into respectively out of the holes (8) between the teeth of said toothing. The clutching and clamping mechanism (4, 5, 14) is connected to the pontoon (2) or work platform, as well as an elevating mechanism (20) functioning in vertical direction in relation to the clutching and clamping mechanism. The toothing is embodied as a series of recesses (8) made at regular mutual distances into the throughgoing angled profile at the vertical longitudinal ribs (9), which recesses (8) are each extending over a predetermined distance from the corner.
