A method of detecting a failure in a pressure compensation system, in which a group of pressure compensators (10, 20) compensate volume changes of a liquid in a chamber (112) of a subsea device, is provided. The group of pressure compensators includes at least a first pressure compensator and one or more further pressure compensators. The pressure compensators (10, 20) in the group are biased so that the pressure inside the pressure compensators is larger than a pressure prevailing in a medium surrounding the subsea device. Based on the detection of drift in a displacement measured for at least one pressure compensator, it is determined whether the first pressure compensator has failed or whether one of the further pressure compensators has failed, thus determining the location of the failed pressure compensator. |
