Abstract (en)
A tool for running in and securing a tubing string includes three concentric mutually rotatable sleeves (15,16,17,18,19). The inner sleeve is formed in upper and lower telescopic parts (17,18,19). When these parts are extended rotation can be transmitted from a landing string (14) via both inner sleeve parts for connection to the hanger. When the two inner sleeve parts are retracted there is no direct drive between the parts but rotation of the upper inner sleeve part by the landing string is transmitted via a sun gear on the upper inner sleeve part, planetary gears on the central sleeve (16), and a ring gear (33) on the outer sleeve (15), for rotating a locking ring (36) to expand a split ring (39) to secure the hanger (10) to a spool (3). <IMAGE>
