In covering the recent San Francisco Bay Bridge incident I have noticed most (but not all) of the news articles have made a small error in terminology. In describing the incident where the Cosco Busan hit the Bay Bridge many prominent news organizations referred to event as a collision when in fact it was an allision.

For clarification: A vessel collides with another moving vessel…. A vessel allides with a fixed object (unless it is submerged) and is presumed at fault.

“At 8:30 am this morning, the Cosco Busan, an 810-foot container ship, collided with the base of one of the towers of the San Francisco-Oakland Bay Bridge while the ship was under the control of a Bar Pilot. The crash created a huge gash in the side of the ship and triggered an oil leak that created an environmental mess in San Francisco Bay.” More to come but Telstar Logistics has the full story from a local perspective LINK.

In related news New York’s Ambrose Light experienced an allision earlier this week but this one seems to be part of a trend. I don’t have specifics on this particular incident but the previous ones we’ve heard of were due to failed crash astern tests, a requirement of the port, that were conducted too close to the pilot station. Gothamist has the details on this one LINK.
