Two Whistle approach?

Yikes, in broad daylight with excellent visibility can that even happen by accident? Was this some planned close 'drive by' collision avoidance drill?

You can watch San Diego bay on a live feed on YouTube!
 
This will likely be human error (a competency error). I hope the Navy investigates it. The causal factors and root causes of a "high value near miss" can often be the same as a "Hit" (incident). About 20% of Near Miss Occurrences have the potential to provide key "lessons" to avoid an incident. It It would be interesting to hear the radio coms for passing arrangements and to know if there were any passing whistle signals used (US Inland Rule 34). Typically vessels do not meet starboard to starboard-but can if they agree.
 
Did you hear the radio communication embedded in the Twitter video in the story? Is that what you are referring to? Is that a horn? Or warning alert sound?

More here for more context. Fascinating and wow 😮

Yes I heard that. But they are REQUIRED by the Rules of the Road (US Law) to exchange passing arrangements well before the last minute radio call. Typically this is done about 5 minutes apart or even longer. It's not supposed to be a guessing game. If the larger ship decided to go right (which is typical), the two ships would have collided. Normally you pass port to port. If youre going to pass Starboard to Starboard, prudent mariners will talk to the other ship well in advance. What does the CIC team do regarding traffic? Nothing?

SWOs': do warships use Pilots in San Diego?

Good question. The CO of my ship would be ripping that bridge team apart long before that situation developed. I wonder if the COs were on the bridge.

It's absolutely mind boggling...having run merchant deep draft ships for 18 years. I just can't imagine this. Do warships use Bridge Resource Management techniques? They are lucky both ships were proceeding so slowly.

This is in broad daylight too. What about a transit through a busy merchant shipping lane overseas on a dark night with no visible horizon? Or a stationing maneuever at night in a large ship formation. Things that go bump in the night, or day, are not good.

I have a headache watching this. Future SWOs: Call the other ship on the VHF well in advance and make "passing arrangements"...don't ask the CO or anyone else. Just do it.
 
Wow. The radio exchange I heard was last minute and sounded like fear in the voice of a JO. There seems to be plenty of space on the red side. And the green side towards the end of the video.
Edited to add OldRetSWO clarified that the wind played a factor.

The Momsen has a pilot onboard per the hotel flag.

Lots of discussion on my SWO community site. The LSD was standing out and going slow and this is a ship with LOTS of sail area and not easy to turn.
General Impressions:

Folks who know the area and LSDs say that the wind was blowing the LSD to the side of the channel where the inbound DDG needed to be. The DDG is MUCH more powerful/manueverable and thus a Stbd to Stbd passage was the best COA.

By the way, the aspect of the picture makes it look a lot closer than it was in actuality
 
In the air force flying world, we call that a "near miss."

Somebody needs a flogging...

The "like" was for the "cat of nine tails." They use that in the Air Force? Had I been in a helo, I would have been doing a serious "over run." I know you guys "under run." Collisions aren't cool at sea or in the air.

Thanks. That puts it in some context. However, if you know the sail area will cause lots of sliding (in wind)...it should be a consideration in the approach...the late VHF call seems to tell a lot.
 
Just saw some additional info that pertains.
Harpers Ferry (the LSD) had been right of track due to prior meeting situation with Tripoli (carrier) and most
likely overcorrected on its turn which placed her on the wrong side of the channel. Lots
of internal discussions ongoing about the incident.

@OldRetSWOP Does USN take near miss occurrences, like this, and use them in simulator training for new OODs/SWO and CO;s? This case has a lot of "free" lessons. Free in the sense there was not contact.

I'm not positive but I don't think they'll be in the sims anytime soon. much more likely to see it discussed with students
as well as various wardrooms and Squadron CO meetings.
