“…-zonal ship/platform design, which means that the network is divided in several zones in such way that operation of electrical equipment is not affected by malfunctions appearing in a different zone [6] -utilization of several distributed generators (e. g. diesel or gas-turbine driven) [8], connected to minimum 2 bus bars -flexible architecture of the network, using various CBs (Circuit Breakers) or tie-breakers, so in faulty conditions the power is transmitted using alternative paths [9] New maritime applications introduce higher generation and load levels, power electronics based consumers [9] [10], more complex networks and higher voltage levels [11]. Moreover, operation of the protective relays may be disturbed by the high start-up currents of motors [3] or by the harmonic generation of the power electronics based devices [9]. All these challenges need to be addressed by the power system protection of the maritime applications.…”

“…Maritime applications are islanded power systems [3] and their protection system is challenged by the specific issues of the maritime sector [4]. Every maritime application needs to fulfill the requirements of one classification society: Lloyd's Register, Bureau Veritas, Det Norske Veritas & Germanischer Lloyd, American Bureau of Shipping or other.…”

An electric fault that is not cleared is harmful in land applications, but in marine and offshore sector it can have catastrophic consequences. If the protection system fails to operate properly, the following situation may occur: blackouts, fire, loss of propulsion, delays in transportation, collision with the cliff, reef or other ships and electrical shocks to humans. In order to cope with the unwanted effects of a fault, several protection strategies are applied, but complexity of the marine and offshore applications is continuously increasing, so protection needs to overcome more and more challenges. As result, development of new protection techniques that can offer improved functionalities compared to the actual solutions for marine and offshore applications is needed. This paper reviews the network topologies in such applications and presents the requirements of a system able to protect them. Also, a brief overview of the protection principles for a generic power system is presented.
