A combined feed-out/feed-in device (20) serves to feed a coilable tubing (12, 12') out or in, respectively, in relation to a rotatable drum (10) during uncoiling and coiling, respectively, of the coilable tubing (12, 12') on the drum (10). The drum (10) is placed on a rack part (16) which is pivotally disposed in relation to a support rack (18) about an axis parallel to the rotational axis (14). In order to obtain a positioning of the feed-out/feed-in device (20), the drum (10) and the coilable tubing (12, 12') in mutual positions of readiness entailing an absolute minimum rigging time, the feed- out/feed-in device (20) is placed on the drum's (10) support rack (18), and an outer end connector (30) is permanently mounted on the outermost end of the coilable tubing (12, 12') after the tubing has been passed through said through-going passage (20').
Un dispositif combiné de chargement/déchargement (20) sert à enlever d'un tambour rotatif (10) ou à amener sur ce tambour rotatif (10), respectivement, un tube d'intervention enroulable et ce, durant les opérations de déroulement et d'enroulement dudit tube enroulable (12, 12') sur le tambour (10). Ce tambour (10) est installé sur un élément de bâti (16), lequel est placé, de manière à pivoter, sur un bâti de support (18), autour d'un axe parallèle à l'axe de rotation (14) du tambour. Afin de positionner le dispositif de chargement/déchargement (20), le tambour (10) et le tube enroulable (12, 12') à des emplacements réciproques n'exigeant qu'un temps minimal de manoeuvre, le dispositif (20) est monté sur le bâti de support (18) du tambour (10) tandis qu'un raccord d'extrémité extérieure (30) est monté à demeure sur l'extrémité la plus éloignée du tube enroulable (12, 12') après que celui-ci a franchi le passage traversant (20').
