Titanic

RMS Titanic was a British ocean liner that sank in the early hours of 15 April 1912 as a result of striking an iceberg on her maiden voyage from Southampton, England, to New York City, United States. Of the estimated 2,224 passengers and crew aboard, approximately 1,500 died, making the incident one of the deadliest peacetime sinkings of a single ship. Titanic, operated by White Star Line, carried some of the wealthiest people in the world, as well as hundreds of emigrants from the British Isles, Scandinavia, and elsewhere in Europe who were seeking a new life in the United States and Canada. The disaster drew public attention, spurred major changes in maritime safety regulations, and inspired a lasting legacy in popular culture. It was the second time White Star Line had lost a ship on her maiden voyage, the first being in 1854.
Titanic was the largest ship afloat upon entering service and the second of three s built for White Star Line. The ship was built by the Harland and Wolff shipbuilding company in Belfast. Thomas Andrews Jr., the chief naval architect of the shipyard, died in the disaster. Titanic was under the command of Captain Edward John Smith, who went down with the ship. White Star Line's chairman, J. Bruce Ismay, survived in a lifeboat.
The first-class accommodations were designed to be the pinnacle of comfort and luxury. They included a gymnasium, swimming pool, smoking rooms, fine restaurants and cafes, a Victorian-style Turkish bath, and hundreds of opulent cabins. A high-powered radiotelegraph transmitter was available for passenger use. Titanic had advanced safety features, such as watertight compartments and remotely activated watertight doors, which contributed to the ship's reputation as "unsinkable".
Titanic was equipped with sixteen lifeboat davits, each capable of lowering three lifeboats, for a total capacity of 48 boats. Despite this capacity, the ship was scantly equipped with a total of only twenty lifeboats. Fourteen of these were regular lifeboats, two were cutter lifeboats, and four were collapsible and proved difficult to launch while the ship was sinking. Together, the lifeboats could hold 1,178 people - roughly half the number of passengers on board, and a third of the number of passengers the ship could have carried at full capacity. The British Board of Trade's regulations required fourteen lifeboats for a ship of 10,000 tonnes. Titanic carried six more than required, allowing 338 extra people room in lifeboats. When the ship sank, the lifeboats that had been lowered were only filled up to an average of 60%.

Background

The name Titanic derives from the Titans of Greek mythology. Built in Belfast, Ireland, in what was then the United Kingdom of Great Britain and Ireland, RMS Titanic was the second of the three s—the lead vessel was and the final ship in the class was. They were by far the largest vessels of the British shipping company White Star Line's fleet, which comprised 29 steamers and tenders in 1912. The three ships had their genesis in a discussion in mid-1907 between the White Star Line's chairman, J. Bruce Ismay, and the American financier J. P. Morgan, who controlled the White Star Line's parent corporation, the International Mercantile Marine Co..
White Star faced an increasing challenge from its main rivals, Cunard Line—which, with the aid of the Admiralty, had recently launched the twin sister ships and, the fastest passenger ships then in service—and the German lines Hamburg America and Norddeutscher Lloyd. Ismay preferred to compete on size rather than speed and proposed to commission a new class of liners larger than anything that had come before, which would be the last word in comfort and luxury. The new ships would have sufficient speed to maintain a weekly service with only three ships instead of the original four. Olympic and Titanic would replace of 1889, of 1890 and of 1907. first departed from a new home port in June 1907 along with the Teutonic, Majestic, and the new Adriatic on the Southampton-New York run.
The ships were constructed by the Belfast shipbuilder Harland & Wolff, which had a long-established relationship with the White Star Line dating back to 1867. Harland and Wolff were given a great deal of latitude in designing ships for the White Star Line; the usual approach was for Wilhelm Wolff to sketch a general concept, which Edward James Harland would turn into a ship design. Cost considerations were a relatively low priority; Harland & Wolff were authorised to spend what it needed on the ships, plus a five per cent profit margin. In the case of the Olympic-class ships, a cost of £3 million for the first two ships was agreed, plus "extras to contract" and the usual five per cent fee.
Harland and Wolff put their leading designers to work designing Olympic-class vessels. The design was overseen by Lord Pirrie, a director of both Harland and Wolff and the White Star Line; naval architect Thomas Andrews, the managing director of Harland and Wolff's design department; Edward Wilding, Andrews's deputy and responsible for calculating the ship's design, stability and trim; and Alexander Carlisle, the shipyard's chief draughtsman and general manager. Carlisle's responsibilities included the decorations, equipment, and all general arrangements, including the implementation of an efficient lifeboat davit design.
On 29 July 1908, Harland and Wolff presented the drawings to J. Bruce Ismay and other White Star Line executives. Ismay approved the design and signed three "letters of agreement" two days later, authorising the start of construction. At this point, the first ship—which was later to become Olympic—had no name but was referred to simply as "Number 400", as it was Harland and Wolff's 400th hull. Titanic was based on a revised version of the same design and was given the number 401.

Dimensions and layout

Titanic was long with a maximum breadth of.
The ship's total height, measured from the base of the keel to the top of the bridge, was. Titanic measured and and with a draught of and displaced 52,310 tonnes.
All three of the Olympic-class ships had ten decks, 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 Titanics 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 above the deck, extending out to either side so that the ship could be controlled while docking. The wheelhouse stood within the bridge. The entrance to the First Class Grand Staircase and gymnasium was 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 Second Class entrance. Just forward of the Second Class entrance sat the kennels, where the First Class passengers' dogs would stay. 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.
A Deck, also called the promenade deck, extended along the entire length of the superstructure. It was reserved exclusively for First Class passengers and contained First Class cabins, the First Class reading and writing room, lounge, smoke room, and Palm Court.
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 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, numerous pieces of machinery and the anchor housings. Aft of the bridge deck was the raised poop deck, long, used as a promenade by Third Class passengers. It was where many of Titanics 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.
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.
D Deck, the saloon deck, was dominated by three public rooms—the First-Class reception room, the First-Class dining saloon and the Second-Class dining saloon. The first- and second-class galleys were also located on this deck. 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.
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.
F Deck, the middle deck, mainly accommodated Second- and Third-Class passengers and several departments of the crew. The Third Class dining saloon was located here, as was the First Class bath complex, containing the swimming pool and the Turkish bath.
G Deck, the lower deck, had the lowest portholes, just above the waterline. The first-class squash court was located here along with the travelling 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 decks over the boiler, engine and turbine rooms.
The orlop deck, and the tank top below that, named because of the water tanks and ballast tanks stored in the ships double bottom,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 two flights of stairs in the fireman's passage; twin spiral stairways near the bow provided access up to D Deck. Ladders in the boiler, turbine, and engine rooms provided access to higher decks in those compartments.
