RMS Titanic
RMS Titanic (/taɪˈtænɪk/) was a British passenger liner that sank in the North Atlantic Ocean in the early hours of 15 April 1912, after colliding with an iceberg during its maiden voyage from Southampton to New York City. There were an estimated 2,224 passengers and crew aboard, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history. RMS Titanic was the largest ship afloat at the time it entered service and was the second of three Olympic-class ocean liners operated by the White Star Line. It was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, her architect, died in the disaster.[2]
Titanic was under the command of Edward Smith, who also went down with the ship. The ocean liner carried some of the wealthiest people in the world, as well as hundreds of emigrants from Great Britain and Ireland, Scandinavia and elsewhere throughout Europe who were seeking a new life in the United States. The first-class accommodation was designed to be the pinnacle of comfort and luxury, with an on-board gymnasium, swimming pool, libraries, high-class restaurants and opulent cabins. A high-powered radiotelegraph transmitter was available for sending passenger "marconigrams" and for the ship's operational use.[3] Although Titanic had advanced safety features such as watertight compartments and remotely activated watertight doors, Titanic only carried enough lifeboats for 1,178 people—about half the number on board, and one third of her total capacity—due to outdated maritime safety regulations. The ship carried 16 lifeboat davits which could lower three lifeboats each, for a total of 48 boats. However, Titanic carried only a total of 20 lifeboats, four of which were collapsible and proved hard to launch during the sinking.[4]
After leaving Southampton on 10 April 1912, Titanic called at Cherbourg in France and Queenstown (now Cobh) in Ireland before heading west to New York.[5] On 14 April, four days into the crossing and about 375 miles (600 km) south of Newfoundland, she hit an iceberg at 11:40 p.m. ship's time. The collision caused the hull plates to buckle inwards along her starboard (right) side and opened five of her sixteen watertight compartments to the sea; she could only survive four flooding. Meanwhile, passengers and some crew members were evacuated in lifeboats, many of which were launched only partially loaded. A disproportionate number of men were left aboard because of a "women and children first" protocol for loading lifeboats.[6] At 2:20 a.m., she broke apart and foundered with well over one thousand people still aboard. Just under two hours after Titanic sank, the Cunard liner RMS Carpathia arrived and brought aboard an estimated 705 survivors.
The disaster was met with worldwide shock and outrage at the huge loss of life and the regulatory and operational failures that led to it. Public inquiries in Britain and the United States led to major improvements in maritime safety. One of their most important legacies was the establishment in 1914 of the International Convention for the Safety of Life at Sea (SOLAS), which still governs maritime safety today. Additionally, several new wireless regulations were passed around the world in an effort to learn from the many missteps in wireless communications—which could have saved many more passengers.[7]
The wreck of Titanic was discovered in 1985 (more than 70 years after the disaster), and remains on the seabed. The ship was split in two and is gradually disintegrating at a depth of 12,415 feet (3,784 m). Thousands of artefacts have been recovered and displayed at museums around the world. Titanic has become one of the most famous ships in history; her memory is kept alive by numerous works of popular culture, including books, folk songs, films, exhibits, and memorials. Titanic is the second largest ocean liner wreck in the world, only beaten by her sister HMHS Britannic, the largest ever sunk. The final survivor of the sinking, Millvina Dean, aged two months at the time, died in 2009 at the age of 97.
Dimensions and layout
Titanic in 1912
All three of the Olympic-class ships had ten decks (excluding the top of the officers' quarters), eight of which were for passenger use. From top to bottom, the decks were:
- The Boat Deck, on which the lifeboats were housed. It was from here during the early hours of 15 April 1912 that Titanic's lifeboats were lowered into the North Atlantic. The bridge and wheelhouse were at the forward end, in front of the captain's and officers' quarters. The bridge stood 8 feet (2.4 m) above the deck, extending out to either side so that the ship could be controlled while docking. The wheelhouse stood directly behind and above the bridge. The entrance to the First Class Grand Staircase and gymnasium were located midships along with the raised roof of the First Class lounge, while at the rear of the deck were the roof of the First Class smoke room and the relatively modest Second Class entrance. The wood-covered deck was divided into four segregated promenades: for officers, First Class passengers, engineers, and Second Class passengers respectively. Lifeboats lined the side of the deck except in the First Class area, where there was a gap so that the view would not be spoiled.[21][22]
- A Deck, also called the Promenade Deck, extended along the entire 546 feet (166 m) length of the superstructure. It was reserved exclusively for First Class passengers and contained First Class cabins, the First Class lounge, smoke room, reading and writing rooms and Palm Court.[21]
- B Deck, the Bridge Deck, was the top weight-bearing deck and the uppermost level of the hull. More First Class passenger accommodations were located here with six palatial staterooms (cabins) featuring their own private promenades. On Titanic, the À La Carte Restaurant and the Café Parisien provided luxury dining facilities to First Class passengers. Both were run by subcontracted chefs and their staff; all were lost in the disaster. The Second Class smoking room and entrance hall were both located on this deck. The raised forecastle of the ship was forward of the Bridge Deck, accommodating Number 1 hatch (the main hatch through to the cargo holds), numerous pieces of machinery and the anchor housings.[b] Aft of the Bridge Deck was the raised Poop Deck, 106 feet (32 m) long, used as a promenade by Third Class passengers. It was where many of Titanic's passengers and crew made their last stand as the ship sank. The forecastle and Poop Deck were separated from the Bridge Deck by well decks.[23][24]
- C Deck, the Shelter Deck, was the highest deck to run uninterrupted from stem to stern. It included both well decks; the aft one served as part of the Third Class promenade. Crew cabins were housed below the forecastle and Third Class public rooms were housed below the Poop Deck. In between were the majority of First Class cabins and the Second Class library.[23][25]
- D Deck, the Saloon Deck, was dominated by three large public rooms—the First Class Reception Room, the First Class Dining Saloon and the Second Class Dining Saloon. An open space was provided for Third Class passengers. First, Second and Third Class passengers had cabins on this deck, with berths for firemen located in the bow. It was the highest level reached by the ship's watertight bulkheads (though only by eight of the fifteen bulkheads).[23][26]
- E Deck, the Upper Deck, was predominantly used for passenger accommodation for all three classes plus berths for cooks, seamen, stewards and trimmers. Along its length ran a long passageway nicknamed Scotland Road, in reference to a famous street in Liverpool. Scotland Road was used by Third Class passengers and crew members.[23][27]
- F Deck, the Middle Deck, was the last complete deck and mainly accommodated Second and Third Class passengers and several departments of the crew. The Third Class dining saloon was located here, as were the swimming pool and Turkish bath.[23][27]
- G Deck, the Lower Deck, was the lowest complete deck that carried passengers, and had the lowest portholes, just above the waterline. The squash court was located here along with the traveling post office where letters and parcels were sorted ready for delivery when the ship docked. Food was also stored here. The deck was interrupted at several points by orlop (partial) decks over the boiler, engine and turbine rooms.[23][28]
- The Orlop Decks and the Tank Top below that were on the lowest level of the ship, below the waterline. The orlop decks were used as cargo spaces, while the Tank Top—the inner bottom of the ship's hull—provided the platform on which the ship's boilers, engines, turbines and electrical generators were housed. This area of the ship was occupied by the engine and boiler rooms, areas which passengers would have been prohibited from seeing. They were connected with higher levels of the ship by flights of stairs; twin spiral stairways near the bow provided access up to D Deck.[23][28]
Features
Power

The two reciprocating engines were each 63 feet (19 m) long and weighed 720 tons, with their bedplates contributing a further 195 tons.[31] They were powered by steam produced in 29 boilers, 24 of which were double-ended and five single-ended, which contained a total of 159 furnaces.[33] The boilers were 15 feet 9 inches (4.80 m) in diameter and 20 feet (6.1 m) long, each weighing 91.5 tons and capable of holding 48.5 tons of water.[34]
They were heated by burning coal, 6,611 tons of which could be carried in Titanic's bunkers, with a further 1,092 tons in Hold 3. The furnaces required over 600 tons of coal a day to be shovelled into them by hand, requiring the services of 176 firemen working around the clock.[35] 100 tons of ash a day had to be disposed of by ejecting it into the sea.[36] The work was relentless, dirty and dangerous, and although firemen were paid relatively generously[35] there was a high suicide rate among those who worked in that capacity.[37]
Exhaust steam leaving the reciprocating engines was fed into the turbine, which was situated aft. From there it passed into a surface condenser, to increase the efficiency of the turbine and so that the steam could be condensed back into water and reused.[38] The engines were attached directly to long shafts which drove the propellers. There were three, one for each engine; the outer (or wing) propellers were the largest, each carrying three blades of manganese-bronze alloy with a total diameter of 23.5 feet (7.2 m).[34] The middle propeller was slightly smaller at 17 feet (5.2 m) in diameter,[39] and could be stopped but not reversed.
Titanic's electrical plant was capable of producing more power than an average city power station of the time.[40] Immediately aft of the turbine engine were four 400 kW steam-driven electric generators, used to provide electrical power to the ship, plus two 30 kW auxiliary generators for emergency use.[41] Their location in the stern of the ship meant they remained operational until the last few minutes before the ship sank.[42]
Technology
Watertight compartments and funnels
The interiors of the Olympic-class ships were subdivided into 16 primary compartments divided by 15 bulkheads which extended well above the waterline. Eleven vertically closing watertight doors could seal off the compartments in the event of an emergency.[43] The ship's exposed decking was made of pine and teak, while interior ceilings were covered in painted granulated cork to combat condensation.[44] Standing above the decks were four funnels, each painted buff with black tops, (though only three were functional—the last one was a dummy, installed for aesthetic purposes and also for kitchen ventilation)—and two masts, each 155 feet (47 m) high, which supported derricks for working cargo.Rudder and steering engines
Titanic's rudder was so large—at 78 feet 8 inches (23.98 m) high and 15 feet 3 inches (4.65 m) long, weighing over 100 tons—that it required steering engines to move it. Two steam-powered steering engines were installed though only one was used at any one time, with the other one kept in reserve. They were connected to the short tiller through stiff springs, to isolate the steering engines from any shocks in heavy seas or during fast changes of direction.[45] As a last resort, the tiller could be moved by ropes connected to two steam capstans.[46] The capstans were also used to raise and lower the ship's five anchors (one port, one starboard, one in the centreline and two kedging anchors).[46]Water, ventilation and heating
The ship was equipped with her own waterworks, capable of heating and pumping water to all parts of the vessel via a complex network of pipes and valves. The main water supply was taken aboard while Titanic was in port, but in an emergency the ship could also distil fresh water from seawater, though this was not a straightforward process as the distillation plant quickly became clogged by salt deposits. A network of insulated ducts conveyed warm air, driven by electric fans, around the ship, and First Class cabins were fitted with additional electric heaters.[40]Radio communications
Marconi company receiving equipment for a 5 kilowatt ocean liner station.
The radio room was located on the Boat Deck, in the officers' quarters. A soundproofed "Silent Room", next to the operating room, housed loud equipment, including the transmitter and a motor-generator used for producing alternating currents. The operators' living quarters were adjacent to the working office. The ship was equipped with a 'state of the art' 5 kilowatt rotary spark-gap transmitter, operating under the radio callsign MGY, and communication was conducted in Morse code. This transmitter was one of the first Marconi installations to use a rotary spark gap, which gave Titanic a distinctive musical tone that could be readily distinguished from other signals. The transmitter was one of the most powerful in the world, and guaranteed to broadcast over a radius of 350 miles (563 km). An elevated T-antenna that spanned the length of the ship was used for transmitting and receiving. The normal operating frequency was 500 kHz (600 m wavelength), however the equipment could also operate on the "short" wavelength of 1000 kHz (300 m wavelength) that was employed by smaller vessels with shorter antennas.[50]

Titanic was laid out in a much lighter style similar to that of contemporary high-class hotels—the Ritz Hotel was a reference point—with First Class cabins finished in the Empire style.[51] A variety of other decorative styles, ranging from the Renaissance to Louis XV, were used to decorate cabins and public rooms in First and Second Class areas of the ship. The aim was to convey an impression that the passengers were in a floating hotel rather than a ship; as one passenger recalled, on entering the ship's interior a passenger would "at once lose the feeling that we are on board ship, and seem instead to be entering the hall of some great house on shore".[52]
Among the more novel features available to first-class passengers was a 7 ft. deep saltwater swimming pool, a gymnasium, a squash court, and a Turkish bath which comprised electric bath, steam room, cool room, massage room, and hot room.[52] First-class common rooms were impressive in scope and lavishly decorated. They included a Lounge in the style of the Palace of Versailles, an enormous Reception Room, a men's Smoking Room, and a Reading and Writing Room. There was an À la Carte Restaurant in the style of the Ritz Hotel which was run as a concession by the famous Italian restaurateur Gaspare Gatti.[53] A Café Parisien decorated in the style of a French sidewalk café, complete with ivy covered trellises and wicker furniture, was run as an annex to the restaurant. For an extra cost, first-class passengers could enjoy the finest French haute cuisine in the most luxurious of surroundings.[54] There was also a Verandah Café where tea and light refreshments were served, that offered grand views of the ocean. At 114 ft. long X 92 ft. wide, the Dining Saloon on D-Deck was the largest room afloat and could seat almost 600 passengers at a time.[55] Third Class (commonly referred to as Steerage) accommodations aboard Titanic were not as luxurious as First or Second Class, but even so were better than on many other ships of the time. They reflected the improved standards which the White Star Line had adopted for trans-Atlantic immigrant and lower-class travel. On most other North Atlantic passenger ships at the time, Third Class accommodations consisted of little more than open dormitories in the forward end of the vessels, in which hundreds of people were confined, often without adequate food or toilet facilities.
The White Star Line had long since broken that mould. As seen aboard Titanic, all White Star Line passenger ships divided their Third Class accommodations into two sections, always at opposite ends of the vessel from one another. The established arrangement was that single men were quartered in the forward areas, while single women, married couples and families were quartered aft. In addition, while other ships provided only open berth sleeping arrangements, White Star Line vessels provided their Third Class passengers with private, small but comfortable cabins capable of accommodating two, four, six, eight and 10 passengers.[56]
Third Class accommodations also included their own dining rooms, as well as public gathering areas including adequate open deck space, which aboard Titanic comprised the Poop Deck at the stern, the forward and aft well decks, and a large open space on D Deck which could be used as a social hall. This was supplemented by the addition of a smoking room for men and a General Room on C Deck which women could use for reading and writing. Although they were not as glamorous in design as spaces seen in upper class accommodations, they were still far above average for the period.
Leisure facilities were provided for all three classes to pass the time. As well as making use of the indoor amenities such as the library, smoking rooms, and gymnasium, it was also customary for passengers to socialise on the open deck, promenading or relaxing in hired deck chairs or wooden benches. A passenger list was published before the sailing to inform the public which members of the great and good were on board, and it was not uncommon for ambitious mothers to use the list to identify rich bachelors to whom they could introduce their marriageable daughters during the voyage.[57]
One of Titanic's most distinctive features was her First Class staircase, known as the Grand Staircase or Grand Stairway. Built of solid English oak with a sweeping curve, the staircase descended through seven decks of the ship, between the Boat Deck to E deck, before terminating in a simplified single flight on F Deck.[58] It was capped with a dome of wrought iron and glass that admitted natural light to the stairwell. Each landing off the staircase gave access to ornate entrance halls paneled in the William & Mary style and lit by ormolu and crystal light fixtures.[59]
