Even worse. Fitz should have seen her running lights, but apparently didn't.
I would be quite surprised if no one on the Fitz saw her running lights. Possible but unlikely.
My guess, speculation. which could be crap.
Typically a Navy vessel has quite a few people on the bridge. I think I saw posts earlier. referring to OOD JOOD CON so up to three officers, My Guess a QM or whatever the navy call the dude steering, and at least a couple of ratings as look out.
According to AIS info.
The ACX was initially on a heading of just under 090 say 088 or 087.
She altered to 070.
According to ACX approx. 10 min prior to Collison. ACX had the Fitz about 40 deg to Port X about 3 miles.
It is quite probable the look out Saw and reported the ACX long before the alteration from around 090 to 070.
I would be wondering if it would occur to a relatively junior lookout to report again when the ACX altered from around 090 to 070. Quite possibly not.
According to the ACX. Around 10 minutes prior to the Collison. The Fitz made a sudden change in course and or speed. Resulting in a collision course.
The ships would be quite close at this time and closing quickly.
Would it occur to a relatively junior rating on look out to report the ACX was on a steady bearing. Or is it quite possible The look out might have thought, I've ready reported the container ship, Its not a new sighting to be reported, Its getting kind of close, But the officers know its there.
So If I was to ask the look out, Did you see the container ship? I would not be surprised if he or she said yes.
If I asked the look out did you see it getting closer, I would not be surprised if he or she said yes.
If I asked the look out did you report it was getting closer, I would not be surprised if the answerer was. No. Why not? I thought the Officers knew it was there and knew what they were doing.
Did you see the flashing light, I would not be surprised if the look out said yes I reported the flashing light.
Unfortunately the flashing light and alteration to Starboard by the ACX appear to have been only about 3 or 4 minutes before impact.
The Collision is virtually imminent both ships are realising what's happening but its already to late.
The above is pure guesswork.
I don't know anything about how a Navy bridge works.
I have seen reports where commercial bridge teams have been asked those kind of questions .
he answer from the look out or QM. Did you see it? Yes. Did it look right? No. Did you say any thing? No. Why Not? I thought he knew what he was doing? Why did you think he knew what he was doing? Because he's the Captain or Because he's the Officer.
Next Question. have you ever had BRM training? Surprising how often the answer is. Yes. We just did that.
The ACX altered from around 090 to 070 because of the line on the chart or ECDIS as per passage plan.
This alteration significantly reduced the CPA with the Fitz but did not result in a collision co.
The OOW on the ACX may or may not have taken the FITZ into account. Quite probably not.
Shortly after the ACX alters from around 090 to 070.
The Officer navigating and or conning the Fitz. Has a reason to alter Co. Why? who knows? Traffic? passage Plan? orders?
Around this time The Officer navigating, conning the Fitz is distracted by something, What who knows? Possibly the reason for his alteration?
Unfortunately he misses the alteration by the ACX.
The Officer navigating, conning the Fitz, Alters to starboard without realising the ACX has just altered almost 20 deg to port.
Unfortunately this now is a collision co.
This maneuver is not challenged.
Nobody else on the bridge notices the problem? Possible.
Or Nobody else on the bridge realises the officer conning the Fitz does not know the ACX has altered Course.
Other members of the bridge team assume the officer conning the Fitz is aware of the ACX. It looks odd but an assumption is made he knows what he is doing.
The action continues to go unchallenged. Quite possibly until the report of the flashing light. If it is ever reported.
By the time the light flashes collision is almost imminent.
According to the ACX about 10 min before the collision the Fitz was about 3 miles 40 deg to port.
The closing speed to have a Collison in about 10 minutes, would be about 18 knots, Closing by about 1 mile in about 3 minutes.
A civilian IMO approved ARPA, can take up to 3 minutes after an alteration to give accurate information.
The ACX altered, The Fitz apparently altered, at least once. during the last 10 minutes before the collision.
Possibly contributing to the Officer navigating/conning the Fitz not realising they were on a Collison Co until possibly only the last few minutes prior to impact.
By the time the situation is assessed and acted upon its to late.
Last minute desperate actions by both ships may have even changed a very near miss into a hit.
Might be complete Bollocks and totally wrong
