The utility model provides a sea transport's of module fixing device, includes: the fixed shaped steel in the fixed shaped steel in upper portion, lower part that being used for on the supporting seat limited pipeline lateral movement is installed to a supporting seat, symmetry, wherein, installs the axial stopper between the fixed shaped steel in the upper portions of two symmetry installations for restriction pipeline axial displacement's position. The utility model discloses not only satisfy the pipeline and fix the atress requirement on not equidirectional temporarily, solved the module at the sea transport in -process, problem that the pipeline of module was retrained, and, the operation of need not getting angry on structure thing formal, greatly reduced the welding interim fixed, repair the influence that leads to the fact to the module paint later stage.
