One of the more interesting vessels in the port of Los Angeles. An emissions barge.
A tall crane mounted on the barge reaches to the exhaust stacks of the diesel engines on ships.
The exhaust is captured and funneled through flexible piping to a dry treatment pollution destruction system also mounted on the barge.
Approx 90% of the diesel pollutants are successfully treated, greatly alleviating air pollution from ships that do not have the capability to turn off their auxiliary engines and plug into shore-side power while at dockside.
