Abstract: The invention relates to providing an ice load monitoring system (500) for monitoring ice-induced loads on a structure of a vessel (501). The vessel structure comprises typically at least a shell plate (102), vertical frames (106) essentially normal to the shell plate (102) and longitudinal frames (104) essentially in the horizontal plane and normal to the shell plate (102). Further the ice load monitoring system comprises a combination of stress sensors (F, S, P) each of which is adapted to convert deformations of the structure into a signal proportional to the deformations. The combination of sensors comprises at least frame bending stress sensors (F), plate stress sensors (P) and frame force sensor (S). The ice load monitoring system (500) comprises also a data processing unit (506), and an information network (508) connecting the sensors (S, P, F) and the data processing unit (506). The data processing unit (506) is adapted to collect the signals from the sensors (S, P, F).
