Safe return to port (SRtP) has become a key core design requirement for the large passenger ships due to their large and dense passenger capacity. The electric propulsion system configuration and division arrangement of a large passenger ship have been designed in combination with the SRtP of the International Maritime Organization (IMO). It discusses how the integrated electric propulsion system should meet the design requirements for SRtP in the case of the flooding or fire accidents within the safety limit. It can provide the design reference for the passenger ship designers and the design of the other relevant systems of passenger ships.

The design pattern and application of the shore power cable management system are quite different according to the different ship type, voltage and capacity. The shore power cable management system of bulk carriers and ro-ro vessels are examined to analyze its application and the existing problems in the various ship types. The conclusion and discussion can provide references for the design and construction of the shore power cable management system on board and the formulation and improvement of the standard.
