AN UNDERWATER FLUID TRANSPORT APPARATUS (10) TO TRANSPORT A FLUID BETWEEN A SEA BED (12) AND THE SURFACE (14) OF THE SEA VERTICALLY ABOVE THE SEA BED. A RISER (20) IS CONNECTED TO A FLEXIBLE PIPE (32) LEADING TO THE SEA SURFACE (14). A RETAINING FLOAT (24) IS INSTALLED AROUND THE RISER IN ORDER TO MAINTAIN THE RISER (20) IN A STRETCHED SUSPENDED POSITION BETWEEN THE SEA BED (12) AND A SUBSURFACE REGION SITUATED BETWEEN THE SEA BED AND THE SURFACE (14) OF THE SEA. THE FLEXIBLE PIPE (32) EXTENDS IN A CATENARY CURVE BETWEEN THE RISER (20) AND THE SEA SURFACE. AN ADDITIONAL FLOAT (28) IS INSTALLED BETWEEN THE RISER (20) AND THE SEA SURFACE (14). THE RISER (20) IS ATTACHED TO THE ADDITIONAL FLOAT (28) TO INCREASE THE BUOYANCY OF THE RISER. (FIGS. 1 & 3) |
