BairdMaritime reports the Chinese are building an all electric vessel for their Maritime Safety Administration, to be used “as a command ship for use in emergency pollution response, particularly in instances of pollution involving dangerous gases at sea.”
- Length: 78 meters (256 feet)

- Design speed: 18 knots
- Range 1,000 nautical miles
Reportedly ower is to be provided by two sets of 650kWh high-performance lithium battery packs.
Maybe there is an error here? That only amounts to 1,743.3 HP/hours. My estimate would be that that would allow only about a half hour at 18 knots, an hour at 14, and two hours at 10, perhaps four hours at six. Appears it would take about 75,000kWh to go 1000 miles at 10 knots. Why would it even have a stack if there is no diesel engine?
