A carrier roller of an S-shaped stinger used in deepwater comprises a support sleeve and a connecting shaft of a carrier roller box, wherein the support sleeve is sheathed at the outer part of the connecting shaft of the carrier roller box; the bottom of the connecting shaft of the carrier roller box is provided with a buffer spring, the lower part of which is sequentially connected with a buffer medium and a pressure measuring device in series; the support sleeve is provided with a plurality of slots and a plurality of adjustable slot holes; and a plurality of bolts with fixed height penetrate through the plurality of adjustable slot holes, and are connected with the connecting shaft of a carrier roller box. As for the carrier roller, all the parts are movable relatively, and the acting force by a load can be automatically adjusted; and simultaneously, the pressure measuring device can record the variation of data, therefore, in-time measurement of the carrier roller with load is achieved; and the load on the carrier roller can be uniform basically, therefore, the stress concentration condition in pipe paving operation is reduced.
