Abstract
A device for laying flexible tubular conduits from a floating support comprises rigid accessories the outer diameter of which is greater than the outer diameter of the conduit. It comprises main, linear winch-type tensioning means (6) for normal lowering of the flexible conduit (3) to be laid. The linear winch has an essentially vertical axis and comprises the last means for guiding the flexible conduit at the level of the floating support (1) and auxiliary holding means (19) which hold the flexible conduit by means of an accessory (21) mounted on the flexible conduit, such as an end fitting or an auxiliary accessory, and enable the main tensioning means (6) to clear a section of flexible conduit on which the accessory (21) is mounted.
