Title
(EN) A DEVICE FOR MOVING ALONG A CYLINDRICAL STRUCTURE AND ITS USE, AND A METHOD FOR WORKING A CYLINDRICAL STRUCTURE

Abstract
(EN)
A device (1) for moving along a cylindrical structure (5), for example pipe-structures in support jacket of an offshore platform. The device (1) comprises a first clamping unit (2A) and a second clamping unit (2B), which are configured for selectively clamping around the structure to hold the respective camping unit (2A, 2B) fixed to the structure. Each of the clamping units (2A, 2B) comprising a substantially U- formed rigid segment (8) forming a gap (23) for taking up the structure (5) inside the gap (23) against rollers (6, 6') oriented transversely for rolling the device around the structure (5). The two clamping units (2A, 2B) are connected to each other by a plurality of longitudinal actuators (3) arranged for acting synchronous in parallel for varying the distance between the two clamping units (2A, 2B) when the device (1) is moving along the structure (5) according to an inchworm principle.
(FR)
L'invention concerne un dispositif (1) de déplacement le long d'une structure cylindrique (5), par exemple de structures-conduits d'un treillis de support d'une plate-forme en mer. Le dispositif (1) comprend une première unité de serrage (2A) et une seconde unité de serrage (2B), qui sont conçues pour serrer sélectivement la structure de façon à maintenir l'unité de serrage respective (2A, 2B) fixée à la structure. Chacune des unités de serrage (2A, 2B) comprend un segment rigide sensiblement en forme de U (8) formant un espace (23) servant à maintenir la structure (5) à l'intérieur de l'espace (23) contre des rouleaux (6, 6') orientés transversalement de façon à rouler le dispositif autour de la structure (5). Les deux unités de serrage (2A, 2B) sont reliées l'une à l'autre par une pluralité d'actionneurs longitudinaux (3) conçus pour agir de manière synchrone en parallèle pour faire varier la distance entre les deux unités de serrage (2A, 2B) lorsque le dispositif (1) se déplace le long de la structure (5) selon un principe de vis sans fin.
