Definitions
- the present invention relates to a structure for transporting, installing and dismantling a bridge of an offshore operating platform.
- the invention also relates to methods for transporting, installing and dismantling a bridge of a platform at sea using such a structure.
- the bridge is mounted on a support structure consisting of at least one support column resting on the seabed or anchored thereto.
- the first of these limitations is the capacity of the hoisting cranes that may require the bridge to be made up of several elements, which significantly increases the cost of manufacturing this bridge and the cost of installing and dismantling the bridge. of the platform.
- the second limitation lies in the fact that this method requires a relatively large window of favorable time to be able to carry out the various operations of transfer at sea in good conditions.
- a second method is to install the deck deck in a single block on the support structure by floating it above it.
- the bridge is arranged on this structure by a ballast-deballasting system.
- a ballasting-deballasting system the deck of the platform is supported by a floating support consisting in particular of two barges.
- the deck of the platform must be manufactured and assembled on the same manufacturing site and then transferred from the manufacturing site to a transfer barge by known means.
- This transfer barge supporting the bridge is then towed to another site to transfer the bridge to two transport barges.
- the transfer barge supporting the bridge is close to one of the transport barges which comprises fixed support means of the bridge.
- the bridge of the platform comprises on its sides, complementary means of engagement with the fixed support means of the first transport barge. These complementary engagement means are engaged on the fixed support means by moving the transfer barge to the first transport barge.
- the second transport barge which also comprises similar fixed support means is moved towards the opposite side of the deck of the platform so as to engage the additional engagement means on the fixed support means of the second barge of transport.
- the transfer barge is then ballasted to transfer the entire load of the bridge on the two transport barges.
- the transfer barge is then evacuated and the two transport barges supporting the deck are towed to the operating site.
- the bridge is then transferred to the support structure which, in the case of a floating structure is then deballasted to transfer the bridge to this support structure.
- the two transport barges can then be reused for another transport.
- the installation of the bridge on the support structure takes place in the open sea and the sea conditions are never perfect and a residual swell remains permanently. Therefore, one of the problems with this method of installation lies in the fact that the elements of the barges supporting the bridge hit the bridge under the effect of the swell causing these elements in a movement back and forth.
- US Pat. No. 6,374,764 discloses a third method of installing a bridge on a support structure which consists in equipping this bridge, on two opposite sides, with legs supporting a barge. Each leg secured to the bridge is associated with a drive mechanism for lifting said bridge when the barges are floating to move it above the support structure.

- the mechanical means for driving each shuttle comprise at least two opposite assemblies, carried by the corresponding shuttle and each formed by a pinion driven in rotation and adapted to cooperate with a rack carried by the corresponding column, and
- the means for temporarily connecting the shuttles with the bridge comprise complementary interlocking members carried by said shuttles and said bridge and locking members of the bridge on the shuttles.
- the invention also relates to a method for transporting and installing a deck of a platform at sea on at least one support column by means of a structure as defined above, characterized in that it comprises the following steps: a) transfer the bridge from an assembly platform to a transfer barge, b) move the transfer barge carrying the bridge and place the transfer barge between two barges of the structure of transport, c) the shuttles are moved upwards on the columns to secure these shuttles with the bridge by the temporary connection means, d) the bridge is raised by the shuttles to move it away from the transfer barge, e) on hold the columns on the sets of support legs and remove the transfer barge, f) lower the shuttles carrying the bridge and fix the bridge on the barges, g) move the barges to bring the bridge to the site operating system comprising said at least one column, h) the bridge is separated from the barges, i) the bridge is raised by the shuttles, j) the barges are moved to place the bridge above the at least one support column, k) the shuttles
