It has been known for a number of years that operation with closed bus i.e. connected sections and sub-sections in different engine rooms, will allow for significant reductions in fuel consumption and running costs of the engines. Operating a system with only two engines will allow operation on higher power per individual engine where the fuel economy will be better.
The disadvantage of running the system in closed bus interconnected mode may make system more vulnerable to faults, so any fault e.g. short-circuit or generator failure may make a total vessel blackout. Our presentation highlights the current technical solution of fault tolerant power systems, and also discusses the significant risks associated with this type of power system.
