| 摘要 |
A method for laying tubular conduits on an underwater surface located at a depth P, particularly an ocean bed, by means of at least a first floating support. The method includes the steps of loading onto the first floating support a length of flexible tubular conduit which is greater than depth P; from said support, laying a length of rigid tubular conduit (5) of which the free end is held by said first floating support; connecting a first end of said flexible tubular conduit (15) having a length greater than the water depth P to the free end of said rigid tubular conduit (5); lowering the rigid tubular conduit (5) and the flexible tubular conduit (15); halting the lowering operation once the first end of the flexible tubular conduit connected to the end of the rigid tubular conduit has reached the bottom (7) while a second end of the flexible conduit (15) is still on the first floating support (1).
