Ship structural stress real-time monitoring system (SSSRMS) achieves real-time monitoring and evaluation of the ship structure strength by implanting strain sensors on the hull structure. The method of the selection of stress monitoring points in SSSRMS was studied. The response functions of structure stress under external loads were obtained through the method of the whole ship structural finite element analysis. The monitoring points were selected in two methods which are finding the monitoring points on the area of high stress and considering the information of sea states. Then the method of strain sensor arrangement was presented according to the stress characteristics of the selected points. Finally, an application example was given.
