摘要:
The invention relates to a structure for transporting, installing and dismantling a fixed oil platform provided with framework elements which are substentially formed by a bridge and at least one supporting pillar. The inventive structure comprises a floating U-shaped shell (11) provided with at least three lifting legs (12) adapted for resting upon the bottom of the sea and a shuttle (30) movable along the lifting legs (12) for displacing a platform element. Said shuttle consists of at least three elements (31) each of which is associated with the lifting leg (12) and is provided with mechanical means for driving on the corresponding lifting leg (12) in a manner independent of the shell (11) of the structure (10) and with means for connecting to displaceable framework element. Methods for transporting, installing and dismantling the bridge or the supporting pillar of a fixed offshore oil platform are also disclosed.

The invention relates to a method and an installation for loading and unloading compressed natural gas on ships (24), said ships being suitable for sea navigation and comprising receiving means (28), said compressed natural gas being storable in tubes (30), installed on said receiving means (28). The installation comprises fixed containers (26) for housing said tubes (30), support means (10, 12) to hold a container (26) supported above the sea surface at a given height, means for lowering said receiving means (28), such as to carry the same below said fixed container (26) and to lift said receiving means (28) such as to lift said fixed container (26) above said given height such as to support the same on said receiving means (28).

摘要:
The invention relates to a device for extracting a material from the bed of a body of water and to the associated method. The device (10) includes a surface apparatus (18), a bed unit (22) comprising material-collection means (34) and a pipe (42) for conveying said material, which connects the surface apparatus (18) to the bed unit (22). The device (10) includes at least one functional line (18) which is flexible along almost all of the length thereof. The surface apparatus (18) includes at least one drum (68) around which the functional line (44) is wound. The carrier pipe (42) is also flexible along almost all of the length thereof, each functional line (44) being disposed around the carrier pipe (42) in order to form a flexible pipe (24). The carrier pipe (42) and each functional line (44) can be deployed together between a rest configuration in which they are wound around the drum (68) and a deployed configuration in which they are deployed towards the bed (14) of the body of water (12). The invention is suitable for earthwork and mining on sea beds.
