The present invention relates to a canister guiding system. The purpose of the present invention is to provide a canister guiding system which supports the vertical movement of a thruster canister, and is able to conveniently and safely repair or replace a pad by allowing the pad to be exposed to outside at a certain position without separating a sliding rail from a guiding rail. The canister guiding system of the present invention comprises a lower guiding rail (11) installed in a structure that is extended in the vertical direction from the lower end of a ship body (20`) forming a trunk of a drill ship; an upper guiding rail (112) positioned on the identical line to the lower guiding rail above the lower guiding rail (111) and installed in the ship body (20`) to be separated at a predetermined gap with the lower guiding rail to form a maintenance space (S) between the lower guiding rail and the upper guiding rail (112); a lower sliding rail (121) combined to the lower guiding rail (111) and installed on a canister to support the movement of the canister (11); and an upper sliding rail (122) positioned on the identical line to the lower sliding rail above the lower sliding rail (121) and installed in the canister (11) to be separated from the lower sliding rail at a predetermined gap. The upper sliding rail (122) maintains the combined state to the upper guiding rail (112) when the lower sliding rail (121) is positioned in the maintenance space (S) to be exposed, and the lower sliding rail (121) is formed to be combined to the lower sliding rail (121) when the upper sliding rail (122) is positioned and exposed in the maintenance space (S). |
