https://www.siliconvalley.com/2021/11/12/new-ship-queue-system-aims-to-cut-congestion-pollution-at-ports-of-la-long-beach/ > A new queuing system will soon require cargo vessels that arrive early to the Ports of Los Angeles and Long Beach to anchor and wait 150 miles off the California coast — rather than hugging the coastline in a large group packed within a 40-mile perimeter — in an effort to reduce ship congestion and the pollution idling ships produce. > The effort, supporters said, will “dramatically reduce the number of backlogged ships at anchorage” off the two ports as the nation deals with an unprecedented supply-chain bottleneck.
