New Evidence on Theory of 'Black Box' Being Switched Off | SY News Ep314

The fact that the police were able to shut the bridge down 30 seconds after they were notified is truly amazing. They very likely saved multiple lives with their quick action.

Just for clarification, "the VDR stopped recording information" means the INPUTS to the VDR stopped sending data, not that the VDR was in anyway offline, as confirmed by the continuous BVR recording..

Thanks for this. It’s extremely useful for those of us with very little direct experience of shipping. Plus it’s an antidote to the conspiracy nonsense.

This has to be the channel offering true facts and not guesstimate. Excellent.

Thank you eSysman. Not only for the time getting the facts straight and putting them here, but for your explanations which apply to ALL manner of 'news and events' of why primary sources are so important, as well as how easy it is to promote misinformation even without bad intentions. As always, your videos are professionally done, and good to watch. Hope you have a terrific Easter weekend, and get plenty of rest. Obviously you've been needing to burn the midnight oil in order to keep these videos coming at such a rate. One added thought, your technical expertise is very useful here.

It is probably more correct to say “During the blackout period the VDR recorded that there was no sensor data being received.” Easy to explain as you said as there wasn’t any sensor data.

I respect your expert opinion on a difficult and complex subject, very much appreciate, your Vlog, well done.

Seeing social media about the recorder drove me nuts. The NTSB press conference was on their YouTube channel. It still recorded voice even when the power went out since all the sensors were without power

I am an ex Marine Engineer, sailed on different types of vessels inclusive Cape size bulk carriers. I also involved in ship building for about 5 years and now retired. To my knowledge when a blackout experienced on board a cargo ship, either the emergency generator or standby main Auxiliary engine should start within 30 seconds or if a battery bank is equipped, system should start and power must be stored within 45 seconds as per SOLAS. At the same time all emergency equipments (ie: Navigation lights, Radio equipments, VDR, emergency lighting in ECR, Bridge, Steering room and other essentials) must be operative. But I do not see any lights switched on this ship after the first or second blackout. Ships are equipped with emergency manuring system and they may have not attempted same. On the other hand ship was heading through a narrow channel without tug assistance causing this disaster which could have saved billions of dollars.

I love this channel because the moderator is so clear and balanced in his comments. I really come away with a better understanding of what is going on. Thank you.

Your information makes a lot more sense than all of the "theories". Bravo E!

This is really great commentary. It is also very commendable that you go back and correct/update information from your previous video when you discover new information. Very respectable.

I'm perplexed. for a number of years I was a Power and Control Systems Tech on an FPSO, which was converted from a norwegian build super tanker. With all the backup DC systems on board on a modern vessel I struggle to believe that the loss of AC power would stop the status signals updating from the various critical systems. I just cant believe that the Voyage Data Recorder would be so vulnerable to AC loss.

the VDR will still be on when the ship was alongside as crews don't turn them off. May help understand the blackouts the ship had when in port.

Outstanding metaphor with police and drivers — who is in command? Perfect.

eSysman Super Yatchs, I have extensive training in marine operations for large vessels of up to 180,000 DWT, which is as much as twice as the M/V Dali 90,000 DWT. According to my knowledge and understanding of this type of departure operation of a vessel motoring on a channel and a fairway clear of traffic, It looks very odd what happened to the M/V Dali. I would suggest to further the ongoing investigation the NTSB is doing, and clear out all of the possible causes of that accident, bst rgs

You always provide the most accurate information which is why I look for your posts. I appreciate that you explain any discrepancies of interpretation quickly and thoroughly. While this is a sensational story and is bound to have all sorts of theories and lots of blame, it was the conclusion of a series of unfortunate mechanical issues and not enough time to correct them. My initial thoughts were that tugs should remain with the vessel until it passed under the bridge but, if it is normal to be at 8+ knots at that point, tugs would not be very effective at correcting the heading in time either. It is fortunate that traffic was light at the time and that the call was made to prevent access to the bridge before the crash! Thoughts and prayers for the families of those who were lost and injured!

Spot on commentary. Very informational.

the follow up came so quickly I never watched the first Black Box video. Keep up the good work!

Thank you , Thank you, Thank you. Finally somebody noticed and corrected a huge misinterperation of what the NTSB said and what the various commenters put out there. Awesome
