摘要

Operations for returning to an underwater station equipped with a well apparatus. The device comprises a rectangular frame formed by tubes 1 and at the four corners of which are fixed vertical fixed tubes 2. Four diagonally disposed radial arms 4 extend from each corner and are fixed to tubes 2. In the longitudinal axis of the frame there is fixed to the arms 4 a well head connector 6 carried by a train of rods 7. One of the arms 4 carries a funnel 8 for guiding the frame. Inside tubes 2 are slidably placed weighted tubes, 11, whose upper part has a shoulder 13, inside which comes to bear an olive 14 crimped to a cable 12, which passes through tubes 2 and 11 and carries at its lower end a guide line connector 10 intended to be locked to a guide post 24. With the device, four guide lines may be positioned and connected simultaneously without being hindered by the encumbrance around the well head.
