Abstract: The present invention relates to a power supply system, especially for a floating vessel, comprising at least two segregated power sections, each constituting a main redundancy group, and each comprising at least one of a power generator adapted to generate an electrical power to a main switchboard and a power consumer, such as a propulsion unit, drawing power from said switch board, and a bus-tie connecting the main switch boards of each redundancy group. The system also comprises at least to segregated directly powered thruster redundancy groups, each including a thruster drive, each being connected to the main switch board of a corresponding one of the main redundancy groups, respectively, the thruster redundancy groups including AC/DC converter means and a DC interconnection connecting the thruster redundancy groups thus proving a loop structure, the thruster redundancy groups being able to draw power from both main switchboards.

Abstract: Energy storage system suitable for retrofitting into a power supply system as well as method and power allocation system related to this. The power supply system comprises at least two segregated power system sections, each constituting a redundancy group, each comprising an AC switch board and at least one of a power generator adapted to generate an electrical power to the switch board and/or power consumer drawing power from said switchboard. The energy storage system is configured to be coupled to the AC switch board in each of the at least two redundancy groups, the unit constituting a common and autonomous energy storage system, the energy storage system including an energy management system adapted to distribute additional power between the energy storage system and redundancy groups, and/or between the redundancy groups through the energy storage system, thus providing an additional segregated power source.
