    I had 2 uncles who served in the Navy during WWII and at every cookout when I was growing up they would argue the difference between a boat and a ship. After a few PBR’s it would get pretty heated. Both served on what they called Battlewagons.

    RIP uncle Frank and Al thanks for your service. 

    LoL I'll bet that got a bit heated at times! Admittedly the definition is a bit vague!

    you would think with all this for warning from the ship the bridge workers would have been told first ,, seems funny no 1,,, told to close both ends of the bridge to traffic ,,, at 1.30 there is no traffic funny no 2 ,, seems like pilot had more than enough time to put plans in motion before first black out , how did he know funny no3,,, power out ship is still going straight , inmo should have missed , funny no 4 ,, second power out ship fires engines back up and turns into bridge pilling[ was going straight] funny no 5,, blow hole joe gets on  tv states no terror attack , what took him a year to go to ohio , funny no 6, something not right here , when dose this idiot volunteer to pay for everything,, funny no 7  he made the rail rd cough up for ohio  funny no 8  could it be u krane dosent have there monthly check yet , and its a we will show you joe hmmmmm  not funny anymore ,, pilot is a U KRANE

    Back down hard with a fixed pitch wheel and the boat will yaw signigantly. This is a known handeling characteristic and often times its counted on for manuvering.

    I forget what it was for variable pitch propellers, something like from full speed ahead (30 knots) to full stop i want to say it was suppose to be somewhere around 2 1/2 times the length of the ship to come to a full stop..... Shakes like a MoFo in the stopping process.

     

     

     

     

    Most boats do crash stop testing or at least the marine architects calculate it. I wonder what the Dali's distance was for various displacements if she was tested?

    Ive never sailed eith anything but a fixed wheel so I would t know from expirence but I have heard they(cpp) are nice.

    I just looked up the Dali's Wikipage and according to that she has a fixed pitch wheel. She also has 4 gensets for power and 3,000hp bow thruster.

    Reality is this shouldn't even be capable of happening.   This is going to cost billions and billions and could have been easily avoided with some common sense steps put in place prior. 

    The NTSB and USCG will almost certainly recomend that escort tugs be with ships until well clear of any hazzards. Also I bet the port inspections of forign ships will be increased as well. Depending on what specifically caused the dark ship situation, there will likely be some changes to the mechanical/electrical systems as well. Sadly many of these changes will seem to be obvious from the get go.

    @Kivalo his does this sound

    Neal

    It sounds quite plausable to me. Pretty much all comercial vessels have multiple power sources and it makes sense that a ship that size would have 4 or 5. I was talking with my captain about just that this morning at watch handover. It'll  be interesting to see what caused this power outage.

    The only thing I would add to the Chief's assesment is when you go hard astern on on a single screw you will introduce signifigant yaw into the equation. Actually with a single screw there is always yaw whenever there is throttle input. This yaw is definitely pronounced enough to turn the vessel, as it appears it did. In my opinion, other than the rudder, this had the most impact on the vessel's heading. JMO though.

    Edit: if it had a variable pitch prop that yaw wouldnt be as bad and possibly even counter act the thruster. Too many unknown to say with any certainty yet.

    When the boat can't fit on a ship....... :thumbsup:

    Use to get yelled at for calling a ship a boat........ a boat goes on a ship and we use to always say well this boat will fit on a ship..

     

    The USS Stark placed on a sea going floating dry dock after being hit with a Missile in the Persian gulf

    This is correct.  :bc:

    Why does my gut tell me they will be making changes all around the US, any cargo ship over X size and X Tonnage will have to have X amount of Tugs along side while navigating with in a certain distance of any bridge. 

    Yeah thats pretty much a given.

  10. I will almost certainly write in my Buddy Rob for Pres. and this retarded guy Donnie for VP.  Donnie was a regular at this dive bar I used to frequent before I was 21. We used to pay him a dollar to eat lit cigarettes.

    I haven't worked on ships in 25 years, but what I spoke of was my personal experience on ships internationally, and on tugs and barges in this country, including Baltimore. We did not have anchors ready to drop when maneuvering. Not that it isn't a bad idea though. Either it is a newer requirement since I was a Merchant Marine, or it is a best practice you are doing.

    Now that you mention it, that might be just for us in fuel delivery.  I am fairly certain its for all ships though. I will have to look it up.

    Sometimes it is a lot harder to drop the anchor without power. Often there is a riding pawl that locks the chain in. In that case it needs to be brought in a touch to release, or with more difficulty and dangerous, needing to be pried out.

    I found out I have a college classmate that is in charge of the NTSB investigation of this. 

    It won't take long to figure out what happened. There are event recorders in the engine room as well as the bridge. The bridge likely has voice recorders also.

     

    Terrible accident.

    No its not harder. We are required to have the anchor ready for immediate deployment specificaly for such a case of loss of power or control of the vessel. The anchor would be made ready in all respects for freewheeling.

    You cant drop the anchor if you have no power and the anchor may or may not stop a ship that size when in motion, that river bottom is more than likely a muddy mess and anchor is to hold you in place when stopped.

    You absolutely can drop the anchor without power. We are required to have our anchor ready for immediate deployment when manuvering for just such a reason.

    I was wondering if the anchor deployment was a cause of the course change into the bridge support.  :dunno:

    Neal

    It could, yes. Backing down hard, which now seems likely, would also have a profound effect on ships yaw.

  14. For those of you interested in this, a guy on youtube, Sal Marcogliano runs a channel called "Whats Going On With Shipping". He does a great job breaking these incidents down. I havent had a chance to check yet but if he doesnt have a video up yet he will soon.
