Everyone took their most valuable belongings with them before they evacuated. [79] A photograph of a drawing in a company prospectus, found in the Welte-legacy in the Augustiner Museum in Freiburg, proved that this was the organ intended for Britannic. SS Britannic (1874) - Wikipedia It is not possible to scuba dive to view the Titanic which is in a much poorer condition than the Britannic because its resting place is so deep: around 12,500 feet under the sea. Did Britannic's starboard propeller become inoperative. Why it was there at the time, or for what ship it may have been originally intended, is the subject of speculation. A group of panic-stricken stewards and some sailors rushed immediately and occupied the two lifeboats. That being the case, Titanic may well have been fitted with a three-bladed central propeller.An extract from a notebook retained by Harland & Wolff giving the engineering particulars of the propelling machinery of vessels that were built by the company.There are several similar books, giving details for no fewer than 747 of the companys vessels. SERVICE NUMBER: 35188. It may have been the case that Olympics three-bladed central propeller paid the price for increased efficiency at the expense of increased vibration, and so the shipbuilders subsequently reverted to a four-bladed one. So, to get an acceptable level of balance with much less vibration, a two-bladed propeller, practically speaking, is the most efficient. In Britannic's case, not only is a four-bladed propeller visible in period photos, but this propeller is also visible today on the wreck. [24], Britannic's keel was laid on 30 November 1911 at the Harland and Wolff shipyard in Belfast, on the gantry slip previously occupied by Olympic, 13 months after the launch of that ship, and Arlanza, launched seven days before. 2023 NYP Holdings, Inc.

As blades are added, efficiency decreases, but so does the vibration level. [7], Externally the largest visual change was the fitting of large crane-like davits, each powered by an electric motor and capable of launching six lifeboats which were stored on gantries; the ship was designed to have eight sets of gantry davits but only five were installed before Britannic entered war service, with the difference being made up with boats launched by manually operated Welin-type davits as on Titanic and Olympic.[8][9]. [47] The first four watertight compartments were filling rapidly with water,[47] the boiler-man's tunnel connecting the firemen's quarters in the bow with boiler room six was seriously damaged, and water was flowing into that boiler room. The History of WWI Hospital Ship, the HMHS Britannic - ThoughtCo With the dive being so deep and challenging, you tend not to think about the casualties when youre down there: Its more important to monitor your life support [and] breathing equipment, he explained. At six o'clock, the patients were awakened and the premises were cleaned up. The force of the explosion damaged the watertight bulkhead between hold one and the forepeak. [42], Life aboard the ship followed a routine. In 1915 and 1916 she served between the United Kingdom and the Dardanelles. Festschrift zur Einweihung der Welte-Philharmonie-Orgel; Sammlung Heinrich Weiss-Stauffacher. (Bruce Beveridge collection. The flagship had four turbine-driven propellers with four blades, a diameter of 16 feet, 5 inches, a pitch of 15 feet and an area of 119 square feet, revolving at 180 revolutions per minute at her designed service speed. The four-bladed central propeller installed during her post-war refit is plainly visible. Rick Ayrton, 63, a retired dentist from Bristol, England, snapped photos of the wreckage of the once-882-foot shiplost in 1916 during a dive off the Greek island of Kea back in May. Work began on the third and final Olympic-class liner, Britannic, on the 30th November, 1911, on the same slipway that Olympic had vacated on the 20th October, 1910, just over one year earlier. After all, if it was entered incorrectly then it would be a simple matter to cross out the 3 and then replace it with a 4.. This image is of a page in a notebook kept by Harland and Wolff showing the propeller specifications for some of the ships . Beaumont, hailed it as the most wonderful hospital ship that ever sailed the seas, according to Lost Liners, a PBS documentary and a companion book of the same name, by Robert D. Ballard and Rick Archbold. It sank after a giant explosion occurred onboard, presumably from hitting a mine, off the coast of Kea on Nov. 21, 1916. The efficiency difference between a two- and a three-bladed propeller is considered less significant than the vibrational difference. [32] On 23 December, she left Liverpool to join the port of Mudros on the island of Lemnos on the Aegean Sea to bring back sick and wounded soldiers. [82] In 1976, Cousteau entered the wreck with his divers for the first time. "Titanic's sister ship Britannic could become a diving attraction in Greece", "24 Apr 1912 WHITE STAR'S NEXT GREAT LINER. A document similar to the British registry entries, giving Olympics technical specifications, printed after 1921 but before 1928, refers to Olympics propellers as they presumably were post-1925. Despite those gory deaths, all other passengers reached safety, and the sinking did not gain the same press attention as that of the Titanic where 1,503 people lost their lives. Water poured in through the portholes as the Britannic headed toward Kea. Time was cut short when silt was kicked up, causing zero visibility conditions, and the two divers narrowly escaped with their lives. Video of the expedition was broadcast by National Geographic, BBC, the History Channel and the Discovery Channel. She could stay afloat (motionless) with her first six watertight compartments flooded. Breakfast was served at 6:30 AM, then the captain toured the ship for an inspection. Many Greek citizens and officials attended the funerals. Upon its completion, the ship measured approximately 882 feet (269 metres) in length and had a gross tonnage of 48,158. The photographic record is therefore of no assistance to us. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Thanks for contacting us. In August 1914, before Britannic could commence transatlantic service between New York and Southampton, the First World War began. In May 1915, Britannic completed mooring trials of her engines, and was prepared for emergency entrance into service with as little as four weeks' notice. It has been assumed that these referred to the propeller configuration following the post-war refit in 1919-20. This story has been shared 399,907 times. The sinking of the ship was dramatised in a 2000 television film called Britannic that featured Edward Atterton, Amanda Ryan, Jacqueline Bisset and John Rhys-Davies. Violet Jessop, the 20th Century Lady Jonah: Part 7 - Impressions There is no reason to question that the port and starboard propellers, driven by the reciprocating engines, were three-bladed on every one of the sisters throughout their lives.2 [30], In April 2007, the restorers of a Welte organ, now in the Museum fr Musikautomaten[de] in Seewen, Switzerland, detected that the main parts of the instrument were signed by the German organ builders with "Britanik". Corrections? More than 1,030 were saved. Intriguingly, when Olympic returned to service for spring 1913, her original four-bladed propeller had been replaced with a three-bladed one. And to be honest its a totally worth it game for the price as well for what it is. HMHS Britannic | Atlantic Liners The third ship was added later, and it was planned to be larger and more luxurious than its sister ships. It might be the case that another document will surface in the future, contradicting this source, and recording that Titanic was indeed equipped with a four-bladed central propeller just as historians have believed all along. Our editors will review what youve submitted and determine whether to revise the article. Since the ship was still moving as fast as it could, the boats were sucked into the propellers, killing those on board. Titanic, Britannic and the Olympic. Please refer to the appropriate style manual or other sources if you have any questions. This story has been shared 165,929 times. Britannic was the largest ship lost in the First World War.[3]. With a gross tonnage of 48,158, she surpassed her older sisters in terms of internal volume, but this did not make her the largest passenger ship in service at that time; the German SSVaterland held this title with a significantly higher tonnage. [citation needed], In total, out of the 1,066 people on board, 1,036 people survived the sinking. What was the explosion that sank the Britannic? The Ephorate of Underwater Antiquities later recognised the importance of this mission and extended an invitation to revisit the wreck under less stringent rules. [12], Construction of the Olympic and the Titanic began in 1908 and 1909 respectively. Harland & Wolff appears to have followed a logical procedure of moving all three propellers to the ship prior to installation, and then fitting them within a short space of time. As Titanic was improved compared to Olympic when she entered service in 1912, so Olympic was im-proved when she underwent her extensive refit in 1912-13. She was operated as a hospital ship from 1915 until her sinking near the Greek island of Kea, in the Aegean Sea, in November 1916. (Authors collection). At this point, Bartlett concluded that the rate at which Britannic was sinking had slowed so he called a halt to the evacuation and ordered the engines restarted in the hope that he might still be able to beach the ship. Encyclopedia Titanica (2008) The mystery of Titanic's central propeller (Titanica!, ref: #6105, published 5 May 2008, generated 2nd May 2023 12:29:50 AM); URL : https://www.encyclopedia-titanica.org/mystery-titanic-central-propeller.html, Editor's Note: This article, originally published in 2008, is related to. [32] The medical equipment was installed on 12 December 1915. [4] It was discovered on 3 December 1975 by Jacques Cousteau, who explored it. (While the Titanic took 2 hours and 40 minutes to founder, the Britannic was lost in about 55 minutes.) [98], After Germany capitulated at the end of the First World War followed by the Treaty of Versailles, Germany handed over some of its ocean liners as war reparations, two of which were given to the company. [75] The A Deck of the ship was devoted in its entirety to the First Class, being fitted with a salon, two veranda cafes, a smoking room and a reading room. Lapland, Harland & Wolffs yard number 393, had propellers with a diameter of 19 feet, 6 inches; Laurentic, yard number 394, had wing propellers with a diameter of 17 feet, 6 inches and a central turbine-driven propeller with a diameter of 10 feet. While every effort has been made to follow citation style rules, there may be some discrepancies. The Britannic, sister ship to the Titanic, sinks in the Aegean Sea on November 21, 1916, killing 30 people.More than 1,000 others were rescued. [58], Compared to Titanic, the rescue of Britannic was facilitated by three factors: the temperature was higher (20C (68F)[60] compared to 2C (28F)[61] for Titanic), more lifeboats were available (35 were launched and stayed afloat[62] compared to Titanic's 20[63]) and help was closer (arrived less than two hours after first distress call[62] compared to three and a half hours for Titanic. Diver captures haunting images of Titanic's sunken sister ship [64]), The first to arrive on the scene were fishermen from Kea on their caque, who picked many men from the water. Survivors were sent home and few arrived in the United Kingdom before Christmas. However, with the start of World War I in 1914, the Britannic was requisitioned as a hospital ship in 1915. "Deep Secrets". After collecting some 3,300 casualties, the ship departed for Southampton, England, and arrived there on January 9, 1916. ADDITIONAL INFORMATION: He was born at Walsall, Staffordshire. He also has authored a number of articles on various related subjects. D/2805/SHIP/8A-E]). Nearly all racing propellers are presently either three- or four-bladed.6Olympic Class Propeller Specifications, 1911-25.Sources include the Andrews notebook, the Harland & Wolff engineering notebook, as well as Britannic propeller specifications, which are partially confirmed by entries in Engineering, February 1914. Charles Alfred Bartlett | Titanic Wiki | Fandom In fact, they were about average in terms of their diameter, if compared with the propellers fitted to smaller liners at the time.In Southamptons floating dry dock once again, some time after the 1928-29 refit, Olympics propellers are visible in this unique view. Thirty men lost their lives in the disaster[68] but only five were buried; others were not recovered and are honoured on memorials in Thessaloniki (the Mikra Memorial) and London. [66] At 14:00 the light cruiser HMSForesight arrived. [10] The ship carried 48 lifeboats, capable of carrying at least 75 people each. The captain ordered the port shaft driven at a higher speed than the starboard side, which helped the ship move towards the island. Aquitania was diverted to hospital ship duties in August (her place as a troop transport would be taken by Olympic in September). It seems that Harland & Wolff had already found the optimal design and was unable to improve upon it, although they did not know that at the time. The Britannic's keel was laid at the Harland and Wolff shipyards in Belfast, just five months before the Titanic was launched. She was laid up at her builders, Harland and Wolff, in Belfast for many months before being requisitioned as a hospital ship. It also wasn't installed on Olympic or Majestic since White Star Line didn't want it. Seewen: Museum fr Musikautomaten, 2007. Omissions? The eerie images show one of the ships baths, complete with corroded taps reading Hot and Cold.. Lunch was served at 12:30 PM and tea at 4:30 PM. Most propellers are made with three blades as a compromise for vibration, convenient size, efficiency, and cost. It does not seem to be waiting to be installed. [84], The giant liner lies on her starboard side hiding the zone of impact with the mine. Before he could do so, two lifeboats were put onto the water on the port side. He maintains a website at www.markchirnside.co.uk. [83], The forecastle machinery and the two cargo cranes in the forward well deck are well preserved. On November 30, 1911, construction began with the laying of the keel. However, at present, no known photos appear to exist showing Titanic's propellers in place and, given that the central propeller is not visible on the wreck, this raises an intriguing question. [9] The acquisition of the ship was planned to be at the beginning of 1914. a ( Artist - Ken Marschall) At 8:35 am, Captain Bartlett gave the order to abandon ship and the crew members started the drill to lower the lifeboats for evacuation. [48] The explosion was on the starboard[48] side, between holds two and three. Britannic certainly had a four-bladed one. Under the glass dome was a white wall above the first-class staircase instead of a clock and a large painting. What is less well know is that the Titanic's sister ship, the Britannic was also lost during the course of the First World War on 21 November 1916. The first to sail were Cunard's RMSMauretania and RMSAquitania. The Admiralty paid the companies for the use of their ships but the risk of losing a ship in naval operations was high. The foremast is bent and lies on the seabed near the wreck with the crow's nest still attached. The crew's quarters in the forecastle were found to be in good shape with many details still visible. Britannic: Patroness of the Mediterranean. (See Halpern, Sam. Further research established that this soldier was a Britannic casualty and his remains had been registered in October 1919 as belonging to a certain "Corporal Stevens". At least one other photo shows the blades of the wing propellers lying beside the Thompson dry dock. Blade pitch: 14'-6" In Britannic's case, not only is a four-bladed propeller visible in period photos, but this propeller is also visible today on the wreck. To judge from the entries for yard numbers 400 and 401, Olympic and Titanic respectively, the records for the ships were written prior to Olympics 1913 refit. The change does not appear to have been a success, since it had certainly been replaced by a four-bladed version by 1919, but its original installation on Olympic highlights the very real possibility that Titanic had been fitted with a three-bladed central propeller in February 1912. The second, the Columbus, renamed the Homeric, compensated for other ships lost in the conflict.[99]. The starboard propeller didnt break, they stopped it in order to use the port propeller to turn the ship because the rudder was unresponsive. (Authors collection), A single-blade propeller would be the most efficient if vibration could be tolerated. [101], The Gigantic is the apparent setting of the 2009 escape-room game Nine Hours, Nine Persons, Nine Doors.
