The invention aims to provide a submarine pipeline bearing device which comprises a lifting limiting device and a bearing limiting device. The lifting limiting device comprises hooks, upper limiting lantern ring portions, lower limiting lantern ring portions and supporting blocks, the upper limiting lantern ring portions and the lower limiting lantern ring portions are connected with one another by lantern ring connecting bolts to form limiting lantern rings, the limiting lantern rings sleeve two submarine pipelines which are preliminarily connected with each other, the hooks are fixed onto the upper limiting lantern ring portions, supporting block connecting bolts are mounted at the upper ends of the supporting blocks, threaded holes are formed in the upper limiting lantern ring portions, the lower ends of the supporting blocks cling onto the outer walls of the submarine pipelines, and the supporting block connecting bolts are mounted in the threaded holes; the bearing limiting device comprises transverse support frames, horizontal guide rails and oblique support frames, the transverse support frames are mounted under the horizontal guide rails, and the oblique support frames are mounted on the sides of the horizontal guide rails; the lower limiting lantern ring portions are mounted on grooved portions of the horizontal guide rails. The submarine pipeline bearing device has the advantages that the submarine pipeline bearing device can be used for connecting and fixing the submarine pipelines and is particularly applicable to accurately arranging underwater pipelines.
