That of the Titanic is a story with many dates. There is that of the firm that made its construction possible, in July 1908, that of its launching, at the end of May 1911, and that of the beginning of its maiden voyage, on April 10, 1912. The most famous of all is, however, the most tragic and the one that has turned it into a legend: April 14, 1912. That day, minutes before midnight, the brand new White Star Line ship collided with an iceberg off the coast of Newfoundland. The impact was so brutal that it took only a few hours for the ship to sink. Now, more than a century later, the Titanic writes another new chapter. One that allows us to understand the courage with which his crew acted. What has happened? What science has given us a new perspective and fascinating of the Titanic. Although the remains of the liner rest a few 3,800 meters deep, in the icy waters of the Atlantic, a group of researchers has carried out an exhaustive 3D mapping of the wreck with which they have been able to generate a ‘digital twin’. A unique copy to date. The work was carried out by Magellan Ltd during the summer of 2022 with the help of remotely controlled submersibles. For more than 200 hours a team of experts analyzed the pediment from top to bottom and produced more than 700,000 images taken from different angles. Thanks to them we have a 3D replica that has already been used for the documentary ‘Titanic: the digital resurrection’from National Geographic and Atlantic Productions and released last year. Why is it important? Firstly because it offers us a unique vision of the wreck, which in turn opens a world of possibilities for researchers. in words by Rebecca Morelle and Alison Francis of the BBC, the scan allows us to observe the liner “as if the water” around it had been drained. It may seem like a simple anecdote, but despite the enormous attention it has generated and the number of studies dedicated to the Titanic over recent years, all the unknowns surrounding its sinking have not yet been resolved. “There are still questions, basic questions that need answers,” recognize BBC News Parks Stephenson, an expert on the ship’s history. The 3-D model is important because it allows researchers to go one step further, abandoning the realm of speculation and theories to rely on evidence, something that until now was complicated by the environment in which the wreck rests. Its depth, temperature and lack of light have made it very difficult for researchers, who have had to settle for fragmented images. And what does it show us? Of everything. From the structure of the ship, split in two during the sinking, to much more detailed details. For example, the number of series of one of the propellers, the damage to the deck where the lifeboats traveled or even the debris scattered around them. “Every square centimeter has to be mapped, even the least interesting parts. For example, in the debris field you have to map the mud. It is necessary to fill the gaps between all those objects,” confessed in 2023 to the BBC Gerhard Seiffert, a member of the expedition. Has it been of any use? Yes. Thanks to all the material collected and computer simulations, experts have confirmed that what probably precipitated the sinking were the perforations that can still be seen in the hull. It is just one of the many clues collected by researchers and which, although they may seem minor, complete the chronicle of the wreck. For example, scanning a porthole shattered during the collision confirms to historians that ice entered some cabins. Another conclusion relevant, achieved thanks to computational models, is that the impact with the iceberg left a series of perforations that extended in a straight line along the hull. Can we go further? Again the answer is ‘yes’. The scan has allowed researchers to ‘sneak’ inside the ship itself, revealing part of the mysteries of the internal chronicle of the sinking. One of the most fascinating chapters is the boiler room. The experts focused specifically on one of its installations, located at the rear of the stern section, right where the ship broke up when submerged, which has made it easier to scan. Again it might seem like a curiosity, but it is not: experts have found evidence that part of the boilers were still working when they were submerged in the icy waters of the Atlantic. And that is important. He tells us a story of sacrifice and bravery about the last hours of the Titanic. What story? During their work, investigators found two clues. One is what we mentioned before: that at least part of the boilers never stopped working, something that can be deduced from their condition. The other was left by a valve located on the deck of the aft section. The 3-D scan reveals that it is open, suggesting that the system that generated electricity on the ship probably remained operational during the most tragic moments. Does that matter? A lot. The activity of the boilers allowed them to continue generating electricity and this, in turn, made it possible for the crew members to have light when they were looking for a way to save their lives. If we take into account that the impact with the iceberg occurred in the middle of the night and that the Titanic sank at dawn, it is not a minor detail. More lighting probably translated into greater chances that passengers could get into boats and survive. Was it that important? “They kept the lights and electricity running until the end to give the crew time to launch lifeboats safely with some light and not in complete darkness,” Stephenson reflects.. “They managed to contain the chaos for as long as possible. And all of that was represented in that steam valve that was in the stern.” … Read more
