A fault protection system of a power system of a dynamically positioned vessel is provided. The power system has a power distribution bus having three or more bus subsections, electric connections including bus ties which connect the bus subsections in a ring configuration, and circuit breakers connected between the bus subsections. The fault protection system includes a generator circuit breaker for coupling a generator to a bus subsection, feeder circuit breaker(s) for coupling load(s) to the bus subsection, a first circuit breaker for connecting one end of the bus subsection to a bus tie that provides an electric connection to another bus subsection, the first circuit breaker being a bus tie breaker, a second circuit breaker for coupling another end of the bus subsection to a further bus subsection, protection relays for operating the circuit breakers, and communication links between protection relays that exchange information via said communication links.
