With two sides of an ABS-R2 power system in parallel, the ship would have no power if both sides have failed. For such a system, we multiply the unreliability (probability of failu... Read more
The power system is configured with equipment in series. In a long chain of equipment, system efficiency and reliability both suffer in the following way. System efficiency = Multi... Read more
Connecting the ship to the shore-side power source in-port with the ship’s machinery shut down. Availability of fast plug connections and seamless load transfer without blackout al... Read more
Engine starting system for the emergency generator. It typicallyincorporates two electrical lines and one hydraulic line. It has redundant engine starting capability to start and t... Read more
The widespread use of power electronics converters for pump and propulsion motor drives in ships has introduced power quality concerns. The power-frequency current and voltage chop... Read more
For an even higher degree of redundancy on board, the redundant power system ABS-R2S is not only physically separated, but also has each propulsion motor built with two stator wind... Read more
During navigation in rough seas, the main engine tripped as a result of the actuation of themain engine overspeed trip induced by racing. After resetting it, crew members made atte... Read more
A ring-bus architecture is often used in high-power ships.It has four generators connected in parallel in a ring bus configuration and no emergency generator. Ship without emergenc... Read more
Typical power system architecture for a large cruise ship with integratedelectrical propulsion. The main generators power the propulsion motors and all service loads from one main... Read more
The podded propulsion system is the largest step forward as propulsion unit in the recent years. The concept is not yet fully developed for all market and power applications, and t... Read more
