This paper elaborates the key technology for the electrical design of DP-3 offshore vessel, including categorization of the operating equipment in electrical load calculation, determination of their working conditions and analysis of their performance; as well as electrical load calculation for normal operation and the operation under single fault. The total installed capacity is determined according to normal operation and the result of single fault load analysis; the influence of the number of engine room on both the total capacity of power station and the number of generator set is analyzed to determine the number of engine room, the number of generator set and the capacity of each generator. Then, composition of the power system, short circuit capacity of the bus-bar, voltage level, ring type,etc. are determined with comprehensive considerations. In addition to this, the load of each bus-bar on the switch board under both normal operating condition and single fault condition are checked; the redundant power supply for propulsion under single fault condition, the transitional power supply for high load operation and the redundant design of auxiliary power equipment on board DP-3 vessel are considered in the electrical system design. The configurations, functions and necessities of power management system for full electrical propulsion vessel is discussed.
