The U.S. Coast Guard has opened an investigation into an alleged "near-miss" with the Nashville Avenue Wharf in New Orleans late last month after a large cargo ship lost power.

The Coast Guard also confirmed this week that the probe would include allegations that the same ship, a British-flagged cargo ship named Anglo Marie Louise, was nearly hit by another ship, which had lost power, while it was docked in Convent the day before the New Orleans near-miss.

A Coast Guard spokesman, Petty Officer 3rd Class Anthony Randisi, confirmed the investigations after The Advocate provided the agency with a social media post with detailed and animated vessel traffic data by a marine dispatcher for Moran Towing Corp.

"The Coast Guard understands the potential magnitude of both situations. We acknowledge they occurred, and we are looking into both instances as appropriate," Randisi wrote in response to questions from the newspaper late last week.

Kind of a dumb question, but does the OT know if the bridges in Louisiana are designed to take a hit from these larger ocean freighters? I know the big bridges in Louisiana like the CCC, Huey P Long, and the I-10 bridge are designed to handle barge hits pretty regularly. They do get hit sometimes by those barges. And I know we've seen the superstructures or cranes on board smack the bottom of some of the bridge decks, but they get repaired without any major issue.

Would really suck to lose a busy bridge for a week for repairs (or worse...full replacement after a tragic, deadly accident).

They get 700-800' vessels as far north as Exxon in Baton Rouge pretty regularly. They certainly look big enough to inflict some serious damage.

If the bridge goes in BR, just divert traffic to the loop.

So two ships losing power? After that ship in Baltimore lost power and hit the bridge?

Is hijacking/cutting a ship's power some new terrorism tactic or something?

How in the hell is an E-4 considered a spokesman for the Coast Guard?

The bridge incident in Baltimore had all the Facebookers losing their shite about driving on bridges...

Trolling through my wife's FB page, I've never seen so many posts about the Causeway bridge.

Goes to show you what social media has done to society.

I directed this exact question to an engineer who was involved with the Huey P Long widening project. He said the HPL bridge piers were originally greatly over-engineered because they didn’t have a clear understanding of the true abilities of steel and concrete and the accompanying design.

His opinion was that the GNO or HPL Bridges piers could withstand any empty ship collision with them and probably a strike by any up-bound vessel.

What would be trouble (in his opinion) is a strike from a loaded large ship down-bound, most especially in high river. Too much kinetic energy.

most have impact barriers but those get destroyed in glancing hits. it they were to take a direct hit of one of these full tankers i bet something similar to the Baltimore incident would happen.

do you? did you specifically say "barge" for a reason. Barge impact loads are completely different than tanker loads.

so you are just grabbing at straws. Both recent impacts werent not "Major issues". They were and we lucked out we had great engineers to figure out a fix and it worked.

near-miss


Stupidest phrase ever. If you nearly miss something that means you hit it. It should be a near-hit.
