Protecting electric ships with rapid DC switching

Potentially critical faults in the high-power DC powertrains increasingly found in ships, particularly ferries, must be isolated as quickly as possible to minimise damage and allow the rest of the system to continue operating as normal (writes Peter Donaldson). Key to this is the application of solid-state power electronics in the form of switches based […]

Ferries to launch with fast charging

Five electric ferries are set to operate around the clock across the North Sea Canal in Amsterdam using a fast charging system developed by ABB (writes Nick Flaherty). They will replace a diesel-powered fleet that dates back to the 1930s, and will be used on three busy North Sea Canal routes that transport more than […]

High-speed marine motor addresses critical need

Rapid acceleration may not be the first thing that comes to mind when considering marine vehicles that serve the offshore industries, but it is important because it increases their operational limits, enabling them to be deployed for longer in higher sea states (writes Peter Donaldson). That is one of the key selling points of Walker […]

Cressall unveils liquid-cooled brake resistors

In electric and hybrid vehicles, regenerative braking is a very effective means of recovering energy by recharging the battery, but sometimes it recovers more energy than the battery can accept (writes Peter Donaldson). This is particularly true for large vehicles such as trucks, buses and off-highway machines on a long run downhill that start with […]
