In an unmanned ship, it is important that the electrical power and propulsion system can remain workable even though fault has occurred to maintain the operation until it reaches the destination on port. This paper provides an overview of the key components such as power converters and motors in the system and also the design and control options for enhancing the availability and reliability of electrical power and propulsion system. Most of these articles have been written by independent authors or organisations, focusing only on their area of expertise. Hence, this paper has provide the compilation of many individual research papers under the literature reviews of power converters and motors which includes the fault tolerance, fault isolation and the different types of fault that will possibly occurred in the system. The comparison of power converters topology, different types of motor and also the control approach will also be discussed and proposed in this paper. To meet the requirements given from Rolls-Royce, Park’s vector approach will be proposed under comparison of the other different kinds of control approach. It can diagnose the fault by the use of analyzing the vector that is already being calculated as part of the drive control. With this, it will ensure that the system remains operational even after the failure.
