Abstract: An uninterruptible power supply, UPS, arrangement for subsea applications, including a container arranged and configured for subsea operation, and the following main modules arranged inside the container: at least one battery module of a predetermined battery capacity; at least one UPS module governing the battery module, the UPS module having a predetermined UPS capacity; at least one control module configured for interfacing and managing the battery module and the UPS module. The UPS arrangement is arranged and configured to vary its overall capacity based on at least the number of battery and UPS modules, wherein the at least one battery module and the at least one UPS module are internally arranged such that the heat losses from the UPS module are used to heat the battery module.

Abstract: A method for estimating the remaining useful life of a pressure compensator of a subsea arrangement, the method including determining displacement data related to displacements of the pressure compensator during a time period; and estimating the remaining useful life of the pressure compensator in relation to a failure mode of the pressure compensator based on the determined displacement data of the pressure compensator. A system including a subsea arrangement and a control system, a computer program product, and a computer program, are also provided.
