Titanic - new detailed scans
« on: April 08, 2025, 03:11:50 pm »

Some new very detailed images of the Titanic wreck which shed new information on the sinking.

They may be available elsewhere on the web.

This type of story comes round every couple of years, no doubt followed by yet another documentary, haven't we all had enough of Titanic stories.

Yes we have but there is some new info here and the scans were done a while back. There is still a lot of interest in the ship.

When I was a lad 60 years ago my Dad took me to the Titanic Engineers Memorial in Southampton. None of them survived and they kept the lights on to almost the end. These latest scans indicate that some of the boilers were still powering the electrical installation when the ship went down. They were brave men and worth remembering.

If you are not interested in the Titanic then please click away now and don't clog the topic with disparaging remarks.

For those who do have an interest, the respected Oceanlliner Designs website has a 'flyover' video of the stern section of Titanic based on the latest 3D scans. It looks like this facility will be made generally available shortly to anyone with a computer so you can do your own viewing. There is a lot of new information.

Underwater wrecks are always interesting as they are a time capsule for when the ship sank. This can be very informative in correcting commonly held conceptions. For example, the Jutland Wrecks book by Innes McCartney, which found many of the ships that were sunk in the battle, demonstrated that eyewitness accounts of the sinkings were frequently wrong. As an example HMS Defence was believed to have disintegrated at the time in a huge explosion but the detailed scans subsequently showed the wreck to be largely intact. Many of the wrecks were discovered to be miles away from their originally plotted positions which called into question the accounts of the battle.

It is all interesting and historical stuff.

Well said Colin
There are Many members on this forum who have been informed by your postings over many years but there will always be a few who just cannot stop having a good old moan, who just cant  read and let it go.


I for one look forward to your postings.

Although I am not entirely interested in the Titanic, I was very excited when they first discovered her.  Some of the following documentaries etc., have been quite interesting, what interests me with this one is, all them years ago when I was at sea - I was told that the purple bands on our epaulets represented the blood of the engineers who stayed aboard the Titanic to keep the lights on.  So, I wonder if this belief would ever be proven.

It seems my reaction to the BBCs announcement of this development of scanning underwater wrecks has been misunderstood.   
I apologise to anyone, especially Colin, who may have taken my statement as a personal criticism.
I have followed the progress of Titanic's discovery since being given a copy of Ballards original book 25 years ago.
It is my own personal opinion that the wreck should be left alone, simply respected.

My personal view is that Titanic should be treated in the same way as Naval wrecks. Look but don't touch and don't retrieve artifacts as there is little if anything to be learned from them. The wreck is only a century old and only just out of living memory. I'll make an exception for Hood's bell partly as it did not originally belong to Hood.

The particular problem with Titanic is that it has become a tourist attraction supporting commercial moneymaking. It will have totally dissolved before very long which is ironic when you consider the ancient wooden wrecks still being discovered are over 2,000 years old. Those in the Black Sea are in an amazing state of preservation.

Something like the Mary Rose is different as it is almost five times older and the ship and the items recovered with it have added greatly to our understanding of life in Tudor times. Vasa is a little younger but again a valuable historical time capsule.

Just my own personal opinions of course...

We shouild be glad the Titanic is at a near unreachable depth or it would be getting "salvaged" by Chinese scrap merchants as has happened to many sunken war graves in the far east.

Hi Colin, I understand the morbid curiosity of wrecks, the bigger and greater the loss of life increases the curiosity. The most interesting insight to this sad sinking was some time ago on t/v when they went through her build, it was suggested that as her rivets were made off caste iron, that when the bow hit the berg the rivets snapped allowing the plates to open up and allow water in. Also when a section of her plate was tested with a hammer blow at the cold temperature then it shattered. As most of the forward underwater hull is below the seabed, everything is conjecture, though the Captain probably committed suicide by walking back into his wheelhouse because he knew he would stand trial for gross negligence and go to prison.  Talking of the Defence at Jutland she suffered the same fate as most sunk that day because off an Admirals insistence off loading twice their designed ammunition stores, consequence the shells were easily stowed below, but the more dangerous Cordite was stowed where ever they found space, on the battle cruisers the anti flash doors were fixed open and they had spare bags lying about the barbet. It was reputed by some that the Defence and the others of her class attached to the former even had them stowed on deck, which would explain that huge flash and she was gone. There was a t/v programme not so long ago about this overloading and consequences, Admirals can course more problems than most and usually Jack Tar suffers.

Hi Dodes,

I have just found the detailed analysis of the wreck of HMS Defence which includes the text from Innes McCatrney's book plus some other material. It supports what you say about cordite being stored where it should not have been and therefore contributed to the rapid sinking. It confirms that both the forward and aft magazines exploded blowing off the bow and the stern but that the ship is otherwise substantially intact and not blown to pieces as was thought at the time. The rapid sinking is likely to have been due to the bow and stern being detached and maybe the keel blown out as well. It makes fascinating reading.

I would doubt that the rivets would have been made of cast iron as it is not ductile but brittle. Rivets need to deform during the riveting process, cast iron even if red hot would likely shatter when hammered.

Well I can only reiterate what was said in the programme, it would not surprise me in the least as in those days metallurgy as we know it was not known, remember not many years before the Tay bridge collapsed because of caste metal fittings on wrought iron. It would be very difficult to make thousands off wrought iron rivets because of the nature of making wrought iron where upon you can easily make thousands of caste iron rivets quite cheaply and fast. Remember you build ships for profit and then all the regs we take for granted now did not exist then and if you built the Titanic now as built it would not be allowed out of the fitting out dock let alone go to sea, she was basically an old fashion sailing ship hull fitted with engines rather than sails.

I forgot to mention when I was working on M.o.D. moorings, some of the older moorings were made of  caste iron and the shackle bolts at the mooring centre were hammered into mushroom heads, these were eventually lifted for scrap followed by wrought iron moorings being replaced with steel. The old caste iron and wrought iron material dating back to early 20th century, the weakest was wrought iron, because of the puddling method of making it used to rust down and in its grain while caste was like steel purely surface rust.
